Apply putty to plasterboard ceilings correctly. Do-it-yourself plaster and putty on a plasterboard ceiling Putty on the corners of a plasterboard ceiling for painting

Any repair carried out independently requires certain skills and knowledge. After all, even the most insignificant, at first glance, mistake can affect the final result. Work with drywall is no exception, because it is not enough to install it beautifully, you need to carry out the final finishing correctly and efficiently. Plasterboard ceiling structures are very popular. They make it possible to disguise defects with minimal effort and cost. In this article we will look at how to putty ceilings with your own hands.

Preparing for work

Before starting work, you need to take care of purchasing the missing tools and materials. If something is missing during the process, it may affect the overall quality of the ceiling. Therefore, you need to take care of all materials before you putty the ceiling. You will need:

• Container for mixing putty.
• Wide brush (maklovitsa).
• Perforator with mixing attachment (mixer).
• Painting knife.
• Spatulas of different sizes.
• Sanding float with paper.
• Serpyanka tape (for hiding and fastening seams).
• Primer, putty.

Before you putty the ceilings, it is important to prepare the room for comfortable work. The floor should be covered with oilcloth or paper and items unnecessary for repair should be removed.

Preparing drywall for putty

Finishing of the ceiling structure should begin one to two weeks after installation. If you do the work right away, the putty may crack. Therefore, before you putty the ceiling, you need to wait for the structure to acclimatize.

Operating procedure:

1. We check the screws. We run a spatula over the surface and look for the presence of unscrewed screws; if found, tighten them to the end. You also need to make sure that there are no half-tightened screws. If there are any, they should be twisted side by side and the holes covered with putty. You need to twist at a distance of at least 5 cm from the overtightened hole.
2. Remove dust with a brush.
3. We cut the joints. To do this, make cuts along the entire length of the seams using a painting knife.
4. Mix putty to seal seams and screws.
5. After puttying and drying the joints, we glue the serpyanka.
6. We sand all putty areas on the ceiling.

After final drying, we clean everything from dust and impregnate our structure with a primer. This process is important and should definitely be followed. Depending on the final decorative finishing A primer may be required before and after you putty the ceilings.

Primer selection

Primer of the ceiling, before putting putty on the plasterboard ceiling for painting, is a mandatory stage of work. The primed surface has increased adhesive properties and does not absorb moisture as much.

Primer consumption on plasterboard structures is significantly lower than on other surfaces. Therefore, very little of it will be used for putty.

Most best option- This is an acrylic primer, it is low cost and excellent for drywall. Drying time depends on the room temperature and is usually indicated on the packaging.

The approximate consumption will be 1 liter per 10-15 square meters. m (when applied in 2 layers). That is, we will need 1-2 liters before puttingty on the ceilings, and 2-4 liters before painting.

Choice of putty

Now there is a fairly large number of different putties on the construction market. You can buy either ready-to-use putty or a dry mixture.

What to consider when choosing putty:

• The level of humidity and temperature in the room should be taken into account. It is recommended to choose putties with the most strength characteristics.
• It is worth paying attention to the drying speed and environmental friendliness of the mixture.
• If you have any doubts or difficulties, consult with the seller to select the most suitable option.

Preparation of putty mixture

Dry putty mixture is different from finished product First of all, the cost, it is several times cheaper. The difference also lies in the timing of use. The dry mixture is suitable for use within the first hours after mixing. The finished putty can be used for several weeks after printing.

Preparing dry mix is ​​a simple process. The proportions vary from manufacturer to manufacturer and should be read on the label. After this, pour in the required amount of water and add the mixture. Beat with a mixer until creamy. To control the consistency, add mixture or water.

How to putty the ceiling correctly?

Since the plasterboard ceiling is quite flat, we apply the finished mixture in one layer (so as not to weigh down the structure).

Stages of work:

1. Using a small spatula, apply the solution to a long spoon or spatula. It should be evenly distributed throughout the fry.
2. It is better to apply the solution with a large spatula. By stretching it across the ceiling, we get a wide and even layer. The layer thickness should not exceed 2 mm.
3. After stretching, remove the remaining mixture from the spatula and reapply the solution evenly.
4. Often, puttying plasterboard structures can be done without applying building regulations. To eliminate minimal unevenness, inexperienced workers can use this tool.
5. The required amount of mixture is mixed as needed. In this way, putty is applied to the entire perimeter of the ceiling.

If the first time it is not possible to lay a layer of 1.5-2 mm evenly, we apply it over the same place several times. Excess putty may appear along the edges; remove it with an empty spatula. When pulling again, the direction of movement of the tool should be the same as the first time.

Ceiling putty for painting

Above is a universal technology for how to putty a ceiling with your own hands. In cases where the finishing coat is paint, we do everything according to the described technology, but in this case it is not necessary to prime, it is enough to remove the dust with a brush.

The peculiarity of the putty technology for painting is that the surface must be perfectly flat. While other types of finishes can hide imperfections, they will remain very noticeable when painted. If the sheathing with plasterboard sheets is uneven, it is allowed to increase the putty layer to 3-4 mm.

The putty dries within 4-7 days.

Putty consumption

In advance, before you putty the ceiling for painting, you need to make an approximate calculation of the material consumption. A small amount of putty is used on the flat surface of the plasterboard sheet. The average consumption will depend on the skills of the technician, the type of putty and the type of surface. With a layer thickness of 1 mm, the consumption will be approximately 0.5-1 kg per square meter. m.

To calculate the total amount of mixture required, for example in a room of 20 square meters. m, multiply the quadrature of the ceiling by the flow rate and get: 20 sq. m x 1 kg = 20 kg of putty mixture. If we are making a ceiling for painting, we need two layers. We multiply the resulting result by 2 and get 40 kg. Approximate consumption is indicated on the packaging.

Puttying internal corners

Plasterboard ceiling structures can have several tiers and imply the presence of external and internal corners. To fully answer the question of how to properly putty a ceiling, you need to study the nuances associated with the corners.

To finish the internal corners, plastic perforated corners are used, onto which the mounting grid is attached. If you don’t have such a tool, you can use a special spatula to make it even.

Before puttying, you need to make sure that all connections are secure. The slightest play in the system will lead to cracking and shedding.

The putty technology is as follows:

• A serpyanka (mounting mesh) is laid in the center of the joint.
• Putty is applied over the entire surface of the mounting grid.
• The corners are smoothed using a corner spatula.

At each stage of work on installing metal or plastic corners, fastening putty is used. The final one is applied on top.

Putty on external corners

The design of external corners is done by joining two sheets. If there is no indentation on the coal, after puttying it will visually stand out from the general appearance. It can be corrected with a large layer of material. In the process of finalizing such corners, a number of factors should be taken into account:

Grinding

Experienced builders rarely sand. But if you are wondering how to properly putty a plasterboard ceiling, you cannot avoid this process.

In addition to a grater and sandpaper, you will need a respirator and goggles. After grouting large flaws, point the lamp at the ceiling, this will help you see all the irregularities.

Plastering the ceiling is done in stages. Everything is done according to technology. Begin sanding work after the putty has completely dried, you can tell by the absence of stains.

Conclusion

There is nothing difficult about puttying a ceiling, and anyone can learn how to properly putty a plasterboard ceiling. By following the technological process, after a while you will be able to perfectly level the ceiling without the help of building regulations.

Many craftsmen who decide to carry out repairs themselves are interested in how to properly putty walls and ceilings. Puttying a plasterboard ceiling for painting is carried out in a precisely defined sequence, because failure to comply with technological standards will lead to the obvious manifestation of all defects on the painted ceiling. In addition, a lumpy surface will cause cracks and paint peeling. To prevent unpleasant consequences, high-quality puttying of the plasterboard ceiling is carried out for subsequent painting.

Puttying a plasterboard ceiling begins with the selection of material. The final result and the aesthetic picture of the final finish are directly dependent on its quality characteristics.

Putty compositions are classified depending on the following factors:

• Degree of readiness before starting the process: dry powders or ready-made solutions. The dry composition is more accessible, is stored longer in sealed packaging and resists temperature fluctuations. Ready-made mixtures require active stirring immediately before use and can perform the intended task even after long periods of time when the integrity of the packaging is compromised (dry powders do not have this property).

• Purpose. The starting solution is intended for the first rough treatment, correction of obvious defects, covering up cracks and joint boundaries. The finishing material completes the puttying procedure, finally leveling the ceiling for subsequent application paint and varnish material. Universal mixtures are equally effective for both stages.

• Component composition. It is advisable to use gypsum solutions during construction work in dry rooms intended for permanent occupancy by owners. Cement mixtures will do a better job in the bathroom, indoor pool, kitchen and rooms without heating. The polymer solution is universal and will cope with leveling and related functions under any conditions.

Complete set of tools

The technological process involves the use of a set of tools and devices:

• in case of purchasing dry powder - a bucket and a drill with a mixer;
• wide brush;
• spatulas of different sizes (wide and smaller);
• roller;
• abrasive net and grater;
• serpyanka painting mesh (will help to disguise and fix the seams);
• primer and putty;
• flashlight to check smoothness.

Before you putty the plasterboard ceiling for painting, you should prepare the space around working area: If possible, remove unnecessary pieces of furniture from the room, cover the floors with oilcloth protection.

In order to calculate the approximate consumption of material, for example, for a room of 25 m 2, we multiply the consumption by 1 m 2 by the total ceiling area: 25 m 2 x 1 kg = 25 kg of putty solution. Before painting, you may have to apply a double layer, so the consumption will double - up to 50 kg. The container also indicates approximate material costs.

The working finishing process most often begins 1-2 weeks after the completion of installation manipulations, when the shrinkage has completely finished building structure. Haste threatens to crack the putty layer.

Before you start plastering the ceiling for painting, you need to level the plasterboard sheets, remove the screw heads that extend beyond the general plane and seal the joints. Self-tapping screws should be screwed into the surface, but do not overdo it, recessing them deeply. In case of applying more force than necessary until the formation of depressions from the self-tapping screws, the latter will need to be removed, filling the holes with mortar, and repeating the attempt to screw in new screws near the hole.

Seam alignment

After you finish screwing in the screws, it’s time to seal the seams. The work is performed in the following sequence:

1. Remove dust from the ceiling with a brush.
2. Cut plasterboard joints without a factory edge at an angle of 45 degrees.
3. Make cuts along all seams with a paint knife.
4. Prepare a starting mixture for leveling seams and screw heads.
5. Carefully caulk the seams between the sheets of drywall.
6. Cover the areas with self-tapping screws with cross strokes.
7. Prime the entire surface.
8. Wait until the soil dries, then glue the serpyanka painting mesh in the corners and at the joints between the plasterboard sheets (the location of the seam is along the center of the serpyanka).
9. Sand the areas that had to be covered with putty.

The priming step cannot be skipped. The primer will increase adhesion (adhesion between the surface and the putty layer) and prevent the absorption of wet vapors. The most optimal primer in this particular case is an acrylic solution, which, moreover, has a low price and economical consumption rate.

Nuances of finishing corners

A plasterboard ceiling can theoretically be a complex structure with several tiers with external and internal corners. In this case, perforated corners will come in handy, which will serve as the basis for gluing the serpyanka. Initially, sickle tape is fixed along the center line of the inner corner, then putty is passed along the masking tape, leveling the corner joints with a special spatula.

The outer corners will need to be reinforced with metal or plastic corners: they need to be pressed into the wet putty material to the required level. The resulting excess must be removed with a spatula, completing the stage of finishing the corner by puttying from the top corner to the bottom, paying attention to both sides of the joining line. Subsequent layers are applied to absolute evenness after the previous ones have completely hardened.

Final putty

Coating drywall with a finishing mixture is the final stage of ceiling treatment before applying paint. If the puttying is done correctly, the ceiling will be smooth, painting will be easy, and the aesthetics and functional performance of the ceiling will delight you for many years.

The gypsum plasterboard itself is already flat, so applying putty in one layer is enough to avoid adding weight to the structure.

Step by step finishing of the ceiling:

1. The ceiling is puttied with a wide spatula, extending the tool and laying the material in a layer not exceeding 2 mm.
2. Having completed leveling, clean the tool from excess mixture and apply the solution to another area.
3. It happens that a smooth layer is not achieved with one layer, then an additional one is applied, eliminating the excess with another spatula.

In order not to miss even the smallest defects, it is advisable to use the construction rule. The thickness of the layer is directly dependent on the angle at which the tool is held to the base. As the angle of inclination decreases, the applied layer becomes thinner. The standard in such work is 60 o. To smooth the solution, you need to fix the blade at an angle of 15°, each subsequent layer overlapping the previous one.

Optimal temperature regime to perform work - +5C o -+30C o. It is advisable not to examine the surface in direct sunlight; the image may be somewhat distorted. It is undesirable to create drafts and leave the room for ventilation - rapid hardening threatens the leveling layer with cracking.

Grinding process

It is assumed that the plasterboard ceiling is even, smooth, without defects and raised protrusions. Any flaw on a painted ceiling is obvious. In order to complete the entire process of leveling the ceiling and preparing it for painting, you need to sand every suspicious area. In addition, finishing grout increases the adhesion of paint to the surface.

The procedure for sanding a plasterboard ceiling with your own hands is carried out using a special grater and fine-grained emery cloth.

Observing precautions and safety precautions, you should wear a respirator and protective eyepieces on your face. Large defects are visible without a thorough examination, but a directed light beam will help identify small defects.

There are no particular difficulties in filling a plasterboard ceiling for painting. Any person is able to master the technology of the process. Guided by a certain structure of work on applying putty and fully preparing the surface for painting, after a while it will be possible to do without building regulations.

Putty work (22 photos)

Drywall - in demand building material. Using gypsum plasterboard you can level any ceiling. But its installation on the ceiling cannot be the final stage in finishing. Before painting it, wallpapering it, tiling it, the plasterboard ceiling must be puttied.

Contents of the article:

After covering the ceiling with sheets of plasterboard, it still needs finishing. The gypsum boards themselves are even and smooth, but not monolithic, so the joints will definitely be visible on the base. In addition, the places where the sheets are attached to the profiles with self-tapping screws will also be noticeable. Before proceeding with the final finishing of the ceiling surface - painting, wallpapering, the surface of the drywall must be covered with putty.

Choosing putty for a plasterboard ceiling

Depending on the composition, putties can be gypsum, cement, or polymer. All three compositions are suitable for puttying plasterboard ceilings, but not for every room. To treat a gypsum board ceiling in a bathroom or kitchen, where a humid environment is possible, it is best to use a cement compound. Do not use gypsum putty in these rooms; this composition does not withstand changes in humidity and may crack. Plastic polymer putties are universal, their consumption is significantly lower than that of others. The main disadvantage is their high price.

Selection of materials for puttying plasterboard ceilings

If you don’t have enough experience, then in addition to the basic tools - a 40-50 cm spatula (for puttingtying the ceiling) and 10 cm (for sealing seams), you will need: a self-adhesive mesh (serpyanka), a roller or brush for priming, primer, putty ( final composition). You should also have a drill and mixer on hand to mix the putty mixture.

To putty a plasterboard ceiling, only the finishing compound should be used. The large fraction of the starting putty is designed to prepare the base for fine satengypsum. When it comes to drywall, the foundation is already there. At the same time, it has excellent adhesion, so there is no need for starting putty.

Note that the putty consumption when processing 1 meter square of ceiling area with a thickness of 1 mm will be about 1 kilogram. To calculate the amount of mixture required, take measurements of the ceiling in the room.

Preparatory work before plastering the plasterboard ceiling

Next, you should check the screws that secure the drywall to the profiles. If the cap protrudes above the surface of the sheet by at least a fraction of a millimeter, this will not allow the spatula to pull an even layer of putty. Ideally, the screw heads should be recessed into the sheet by 0.5-1 mm. Only in this case will the ceiling putty proceed without interference.

To determine which screws need tightening, it is enough to use a spatula along the places where the gypsum plasterboard sheets are attached to the profiles. Self-tapping screws that protrude will cling to it.

Pay attention to the joints of the plasterboard sheets - there should be no separation of the cardboard from the plaster. If this happens, you should carefully cut the paper right down to the spine. The resulting wrinkle must be treated with sandpaper. If this is not done, the putty may peel off along with the paper.

Primer of plasterboard ceiling before applying putty

If there is no possibility or desire to prime the entire surface of the ceiling, then it is imperative to treat at least the seams and corners. A lot of dust settles on the seams, which impairs the adhesion of the surface to the putty. If you plan to glue wallpaper to the ceiling, then you should prime the entire surface of the ceiling, otherwise, when removed in the future, they will peel off along with the cardboard base of the gypsum board.

Any primer that is designed to work in conjunction with putty is suitable for treating plasterboard ceilings. Use a roller or brush to apply. Then leave the ceiling to dry. This usually takes from 1 to 3 hours.

Technology for puttying seams in plasterboard ceilings

Puttying joints in a plasterboard ceiling plays a vital role in leveling the surface of a suspended structure. Not only the seams are subject to sealing, but also the screws on which the gypsum board is attached. Sealing of seams is carried out in two ways: using a self-adhesive mesh or paper tape.

Using self-adhesive mesh for puttying seams

We carry out work in the following sequence:

• We dilute fugenfüller in a small amount of water, since its shelf life is no more than half an hour. The consistency of the composition should be like thick sour cream.
• If putty is used, then we use the same composition to attach the serpyanka as for treating the entire surface of the ceiling. We dilute it in accordance with the manufacturer's instructions.
• Apply fugenfüller or putty to the seam with a narrow spatula. We fill the seam so that a reference point for its location remains, that is, not completely. Otherwise, you can glue the mesh not where the seam is located.
• Cut the serpyanka to the required size and apply it to the seam. We recess it a little into the fugenfueller.
• After all the seams are sealed with self-adhesive tape, take a wide spatula and apply the putty mixture in a smooth, even motion, without pressing too hard.
• When applying, hold the spatula at as sharp an angle as possible to the sheet of drywall. This way you can achieve an even filling of the seam without pressing.

When using a self-adhesive mesh, make sure that after gluing there are no threads sticking out anywhere. Trim them carefully with a utility knife before starting to putty.

Using paper tape to putty joints

We carry out the work in this order:

1. Apply the prepared finishing putty to the seams using a narrow spatula. Make sure that the seam is not filled completely.
2. Let the putty layer dry and cut the paper tape into strips of the required length.
3. Glue the paper to the surface of the sealed dry seams using PVA glue. We wait for the glue to dry completely.
4. We completely putty the seams in the same way as when gluing “self-adhesive” tape.

Please note that each layer of the compounds used must be completely dry before the next one is applied.

Puttying cut seams in a plasterboard ceiling

We seal the cut seams in a different way. We open the edged seam with a painting knife and fill it with a special mixture for sealing gypsum board joints. This is offered, for example, by Knauf - Uniflot. Apply the mixture in two stages. We take a break between them to allow the composition to dry. The application procedure is no different from sealing factory seams using conventional putty. Lightly rub the dried mixture into the seams with sandpaper.

Puttying screw heads in plasterboard ceilings

To seal holes from self-tapping screws in sheets of drywall, use a narrow spatula and finishing putty. The process is carried out in a cross-shaped manner. Apply the putty mixture lengthwise and crosswise to each self-tapping screw individually, so that the grooves of the screw heads are filled and their heads are completely hidden.

You should start puttingtying the self-tapping screws after the sealed seams in the plasterboard ceiling have completely dried.

Features of puttying corners in a plasterboard ceiling

The work is carried out in two stages:

• We putty one side of the corner according to traditional rules: using a narrow and wide spatula. Apply the putty at an acute angle without pressing hard.
• After one side of the corner has dried, we putty the other. If necessary, we also treat the third side after the previous surface has dried.

Technology for finishing puttying of plasterboard ceilings

We do it like this:

1. Apply a small layer of putty onto a large spatula, distributing it along the entire length.
2. Apply putty to the ceiling with a large spatula and stretch it along the plane. At the same time, we try to maintain a thin, uniform layer - about 1-2 mm. We apply it quickly, since the plasterboard ceiling should be puttied at once to avoid cracks.
3. If you do not have enough experience, it is better to use a construction rule. Cut off the excess layer with the cone-shaped part of a tool soaked in water. We remove the cut putty from the rule with a small spatula and send it back to the general container with the composition.
4. Leave the fully treated ceiling to dry until the next day.
5. Remove the stains that remain after the first stage of work with a large spatula using a small spatula. We hold it like a chisel and cut off the excess putty. Let the ceiling dry completely.
6. After the putty has dried, we proceed to the initial sanding of the ceiling. To do this, sand the surface with sandpaper, eliminating large scratches and irregularities.
7. Finishing putty on a plasterboard ceiling is the application of a second layer of putty. Apply a thin layer of putty using the same technology as the first layer.

If you are puttingty on a plasterboard ceiling before painting or pasting with thin vinyl wallpaper, then two layers may not be enough. It may be necessary to apply a third coat of putty.

Grouting putty on a plasterboard ceiling

Keep in mind that you should wait until the putty on the ceiling is completely dry. This usually takes 4-7 days. Some people are afraid of drafts while drying the ceiling, but putty is not wallpaper. Therefore, you can safely ventilate the room as best as possible. You can determine whether the putty has completely dried by its color: it should disappear dark spots, and the surface becomes smooth and matte in texture. Now you can begin finishing sanding the ceiling.

For grouting we use zero-grade sandpaper. We process the surface in a circular motion. To make it more convenient to work, you can use a special grater with clamps for sandpaper.

The final “finishing” of the ceiling to perfect condition It is recommended to use light. To do this, you need to install a small spotlight on a tripod. A regular table lamp will also work. Direct the light at the ceiling at different angles. This way you will be able to notice even the slightest flaws in the putty.

Be sure to use a respirator and goggles while working, since the procedure for sanding a putty surface is quite dusty.

A plasterboard ceiling has many advantages; more specifically:

• it hides the uneven surfaces of the main ceiling and communications laid along it;
• it allows you to create both a flat surface and fancy design designs;
• with its help you can create original lighting solutions in a room by dividing individual zones and highlighting the central part with the help of traditional chandeliers.

However, in order for the plasterboard ceiling to look its best, it is necessary that high-quality correct preparation, leveling or puttying be carried out. Leveling the ceiling can be done with your own hands, but you need to prepare for the fact that the work will be difficult and will require your full concentration. The peculiarity of a plasterboard ceiling is that any irregularities with the lighting on will simply catch your eye.

Puttying a plasterboard ceiling before painting is necessary:

• for sealing seams between sheets;
• to reduce paint consumption;
• to improve the adhesion characteristics of the surface.

So, how to properly putty a plasterboard ceiling? This is what we will discuss in today’s article.

What tools and materials are needed?

To putty the ceiling you will need:

• a container in which we will mix the putty;
• drill with mixer;
• brush-brush;
• 2 spatulas - wide (up to 40-50 cm) and narrow;
• corner spatula;
• painting knife;
• grinding float;
• carrying lamp for identifying irregularities;
• a stepladder or sawhorse on which we will work.

The choice of materials depends on the master, but you will definitely need:

• serpyanka;
• primer;
• putty;
• finishing putty.

Choice of putty

If there is nothing complicated with the tools, then the choice of putty for the ceiling should be taken seriously. Each master works with the putty to which he is accustomed or which suits him best in price. Puttying the ceiling is a mandatory procedure before painting, because despite the smooth surface of the gypsum board sheet itself, it is necessary to hide the fastening points with self-tapping screws and the seams between the sheets.

The modern building materials market offers 2 types of putty mixture: ready-to-use in buckets and dry, which needs to be prepared. Liquid putty mixture is undoubtedly very convenient for work, especially for non-specialists, but it is more expensive.

If you decide to carry out the work of puttying drywall yourself and have no budget restrictions, this is best option. If you have experience with puttying drywall (for example, walls), you will also not have problems with thinning and working with dry putty.

In the store you can find 3 types of putty.

1. Leveling- for rough work, sealing cracks, chips, screws, seams. Depending on the manufacturer, it can be applied in a layer of up to 5 mm.
2. Finish- a composition that is applied at the very end of leveling and subjected to grinding. This is a fine-grained putty, which is recommended to be applied in a layer of no more than 1 mm.
3. Universal putty, which is designed for any type of finishing work.

Based on their composition, putties are divided into:

• plaster, not subject to shrinkage, but not moisture resistant;
• cement, moisture resistant, but which may crack when dry; this is the most suitable material for treating ceilings in damp rooms (kitchens, bathrooms);
• polymer- have a lot of advantages, but are more expensive than those described above.

Let us repeat once again: choosing a putty is a matter of budget and experience.

Putty consumption

When calculating the putty consumption, you need to take into account the nature of the surface. If the room is semicircular or has rounded walls, partitions, supports, etc., that is, there are quite a lot of seams between sheets of drywall, then the flow rate should be b O greater. In this case, the consumption of dry putty on cement should be calculated using the formula: 1.1 x 1 sq. m. Gypsum putty A 1:1 ratio will be sufficient. You will need even less glue-based putty: 0.5 kilograms per 1 square meter.

To calculate, you will need to measure the surface area of ​​the ceiling. Immediately estimate how many layers of putty you will put, taking into account the level of your skill.

Preparation of putty

The finished putty does not require any preparation. You just need to open the container, scoop the material onto a spatula and get to work right away. To take a break, simply cover the bucket with a tight lid.

Things are different with dry putty, since it will have to be prepared. You need to prepare dry putty in parts so that it does not set while you work. Cooking instructions are written on the packaging. A third of the water is poured into the cooking container. One person mixes the composition with a mixer, and the second gradually pours in the putty until the consistency of thick sour cream is obtained. Then the composition should be left to set for 5 minutes, and then mixed at low speed for 1 minute.

Prices for gypsum putty

After preparation, the material cannot be stirred or diluted with water, so as not to destroy the molecular bonds. After thickening, the residue will have to be thrown away: thickened putty, improperly diluted with water, will leave lumps and grooves on the surface. The solution should be prepared for approximately 2 hours of work - this is its lifespan. Please note that it is much more difficult to putty the ceiling than the walls, because your hands get tired faster in the position on top.

Preparing the ceiling for puttying

Before starting puttying work, it is necessary to prepare the drywall. First you should check the screws to ensure they are not sticking out above the surface. The self-tapping screw must be recessed into the gypsum board by 1 mm. If it is recessed more, it needs to be twisted onto a longer self-tapping screw. If it is not screwed in enough, you should tighten it carefully, without squeezing it.

Priming is necessary to improve adhesion so that the paint does not crumble later. You should buy a special primer designed for processing gypsum boards: the most popular acrylic primer. Alkyd primer is not recommended for this type of work, as it may swell during the work. You need to work with a brush or roller, paying special attention to priming the seams.

Seam processing

Processing of seams is necessary so that as much putty material as possible can fit inside the voids. Otherwise, after a couple of years of use, the seam may crack.

Table. Processing seams on a plasterboard ceiling.

Corner processing

If the plasterboard ceiling is multi-level, you cannot do without processing the corners. The principle of operation is the same as with processing seams, but instead of serpyanka you can use metal corners. On sale you can find metal corners with serpyanka, specially designed for processing the corners of plasterboard surfaces.

To prevent the metal corners from protruding too much from the surface of the sheet, some craftsmen make a cut along their length and remove the top layer of cardboard. The cut is also pre-primed. The metal corner is then pressed into the sheet so that the perforation is filled with putty, and is also puttied. To work with corners, you must use a special corner spatula.

Apply the putty to a wide spatula with a falcon and begin the puttying with a wide movement of the hand. It is necessary to apply as thin a layer as possible, stretching the mixture over the sheet so that the layer thickness does not exceed 1-2 mm. The putty will be applied in 2-3 layers, so at the first stage there is no need to pay attention to the scratches left by the spatula.

The entire surface of the ceiling is treated in the same way. Then we wait a day until the material dries completely. Completely dry putty will white, wet areas - gray.

Large grooves are removed with a grater and sandpaper. All puttying work must be carried out in a respirator to avoid inhaling dust. At the end, we prime the first layer of putty again with a roller and wait for it to dry completely.

Step 4. A second layer of putty is also applied. When applying it, you need to ensure that there are as few scratches as possible. If the layer is applied evenly, then a third layer is not required. After the second layer has dried, the surface is sanded with sandpaper.

Step 5. Lastly, a fine-grained finishing putty is applied. The principle of application is the same, but the evenness of the application should be controlled with a portable lamp directed at an angle to the ceiling surface. This way, all the irregularities on the ceiling are better identified.

First, the finishing putty is applied, dries, then the excess is sanded off. If depressions are visible somewhere on the surface, another layer is applied. For sanding, it is better to use zero-grit sandpaper.

Step 6. Finally, another coat of primer is applied. You can prime the last time immediately before painting the ceiling.

After this, all work can be considered completed. You need to especially carefully smooth the surface under glossy paint, because matte paint can hide minor irregularities. Such thorough smoothing of the surface is not required if you decide to cover the ceiling decorative plaster or paste it with wallpaper (in some interiors this type of finishing is also found).

Plasterboard ceiling

For many, a very pressing question is “how to putty the ceiling correctly?” so that it looks great. The answer lies in correct selection plaster, compliance with puttying rules and availability necessary tools. But the main role in this matter is played by the choice of plaster.
Plastering a plasterboard ceiling is carried out to eliminate large irregularities. At the beginning of leveling, it is applied in a thick layer. Therefore, its quality and appearance are of great importance, since the wrong choice of mixture can cause the formation of cracks.
Plaster can be:

• based on gypsum. A more expensive type, but it has an impressive list of advantages that definitely compensate for the price. The advantages of gypsum-based plaster include: ease of use, it creates a smoother surface, creates a favorable microclimate in the room, and has high sound and heat insulation;
• based on cement.

Types of plaster

Therefore, the choice of mixture should be made based on further finishing work. When preparing for painting, it is recommended to use gypsum plaster, and when wallpapering - cement.
Pay attention! When choosing plaster, it must have high adhesive properties in order to adhere more firmly to the working surface.

Tools required for work

To make puttying of a plasterboard ceiling easy and quick, you need to have the following tools on hand:

• drill;
• bucket;
• roller;
• large spatula – 40 – 50 cm;
• small spatula – 10 cm.

This set of tools will be sufficient for people who already have the necessary experience in this matter. If your level is slightly lower, then you will need additional tools to putty the ceiling;

Plasterboard ceiling putty technology

So, the question is “how to putty the ceiling correctly?” won't scare you anymore. In order to more fully imagine the picture of this process, we will analyze the technology for carrying out such procedures. Puttying a plasterboard ceiling with your own hands consists of several successive stages:

• surface preparation;
• putty directly;
• grinding.

The preparatory stage involves performing the following manipulations:

• sticking an adhesive mesh to the joints of plasterboard sheets. Instead of a mesh, you can use a fugenfüller;
• preparing the putty mixture. To do this, fill 1/3 of the bucket with water and gradually dissolve the dry mixture in it, while simultaneously stirring it with a drill until it becomes “thick sour cream.” The resulting solution should stand for 5 minutes. Then it needs to be stirred again and can be applied to the joints of sheets and screws;

Preparing the putty mixture

• Upon completion of puttying, the entire working surface must be primed.

Direct puttying of plasterboard ceilings is carried out only a day later, after all the necessary preparatory work has been carried out.
Before starting puttying with your own hands, make sure that the preparation has been carried out efficiently and that there is no adhesive mesh sticking out anywhere. If in some places it partially shows through, then it needs to be carefully cut off with a construction knife.

The final sealing of the ceiling looks like this algorithm:

• preparing the finishing putty according to the instructions written on the back of the package. Next, a small layer is used to cover the entire surface of the ceiling being treated. You need to remove the mixture from the bucket with a small spatula, and then transfer it to a large spatula;
• Using a large spatula, distribute the prepared mixture along the entire length of the ceiling;

The final stage of putty

Pay attention! The putty should be applied in a very thin and even layer at the final stage. The optimal layer thickness is no more than 1-2 mm. Everything needs to be done quickly, as cracks may form. Using the building rule (its cone-shaped side), you need to remove the excess layer.

Upon completion of all the work done with your own hands, the ceiling should dry throughout the day. If there are minor stains, they can be carefully removed with a small spatula. This is followed by the polishing stage.

Carrying out grinding

Sanding after puttying drywall should only begin after the mixture has completely dried. This takes quite a long time - about a week. The surface is ready for sanding after the ceiling has acquired an even matte color.
Using a special grater and sanding mesh, the entire surface should be treated. As a result, your ceiling will become perfectly flat.
Plastering a plasterboard ceiling is quite simple. This procedure can be done with your own hands. If you follow all the recommendations, you will have a perfect and smooth surface.
