Do-it-yourself putty is an integral part of plastering and painting work. Especially if you need to level the surface of the ceiling. As you know, only two millimeters in thickness can be leveled with putty. Everything else is done gypsum plaster. This video provides an example of preparing a ceiling for painting using putty.
For this work you will need several wide spatulas, putty, metal trowels, a device, like in a roller, for moving at height, or use a stepladder or scaffolding. When everything is prepared, you can start working on the ceiling.
First you need to prime the ceiling deep penetration to provide long-lasting protection ceiling covering. In turn, the primer itself comes in three types. Acrylic, alkyd and glyphthalic primers. Their drying depends on the air temperature in the room and many other factors.
Drying time from five hours to a day. After you have primed the ceiling completely and let it dry, you can begin to putty. After applying the primer layer, you need to let it dry and only then can you apply the putty. It is necessary to putty from the corners in order to initially remove each corner and gradually move the spatula along the ceiling, carefully leveling it.
After the ceiling is ready, be sure to let it dry! The putty layer dries after one day, i.e. 24 hours from the moment of application. The first layer of putty is called rough and is applied to a thickness of 3-4 mm, and after it has completely dried, a finishing layer of 2 mm is applied, it is this layer that will level the ceiling and smooth out unevenness of the ceiling. After the finishing layer has dried, you can begin painting. For those who are interested in how to putty a ceiling for painting, watch this video. Enjoy your viewing!
The question of how to putty a ceiling for painting arises for everyone who has started a renovation. ceiling structure and is going to do it with his own hands. Finishing the ceiling involves several stages, including leveling the base before directly applying paint. Regardless of the base material, cracks may appear on the ceiling over time, which lead to peeling of areas of the painted surface. To avoid such problems, it is necessary to correctly putty the ceiling, which will provide a perfectly flat and smooth plane for maximum comfort and high-quality coloring.
Answering the question about how to putty a ceiling for painting, it must be said that a properly selected set of tools is of great importance in the work. For leveling, priming, direct puttying and painting the ceiling, you will need the following devices, which must be prepared in advance so as not to be distracted during the work process:
- electric drill with a mixer attachment and a container for mixing the composition;
- roller with a long handle for priming and painting;
- narrow and wide metal spatulas, as well as a small rubber spatula and trowel;
- construction float, abrasive mesh or sandpaper for sanding;
- a grinding machine for grouting the ceiling surface and removing old paint;
- paint brushes different sizes for removing dust from the ceiling and painting;
- respirator, goggles or mask to protect against inhalation of dust.
Preparing the ceiling for puttying
Plastering the ceiling for painting begins with thorough cleaning and preparation of the surface for subsequent work. First you need to remove the old finish - remnants of wallpaper, wallpaper glue, whitewash or paint. Wallpaper is easiest to remove; to do this, you need to run a wet sponge over it and let the liquid absorb; after 10-15 minutes, the material is easily removed with a spatula. The remaining small fragments must be removed from the surface with a wet cloth.
Advice! To clean the ceiling from old water-based paint with your own hands, you need to use a sander or a regular spatula, after softening the paint layer with water. The process of scraping paint produces a lot of dust, so a respirator and goggles are essential.
After the surface has been cleaned, it is recommended to treat it with a primer to increase adhesion between the finishing layers; for this, experts recommend choosing deep penetration compounds. To enhance the effect, it is better to apply two layers of primer, with one applied in a perpendicular direction to the other. The primer must be distributed evenly, without leaving marks from the brush or roller; the tool should be held at an angle of 50-60 degrees to the base. It is better to choose a roller for priming with short pile; during the work you do not need to press it hard so that your hands do not get tired ahead of time.
Elimination of irregularities
Do-it-yourself putty will not bring the desired result if there are strong differences and deviations from the level on the ceiling surface. Any imperfections will clearly appear on the painted surface, especially under artificial lighting. Therefore, before you putty the ceiling, it is necessary to eliminate these defects and make the base as even as possible.
To determine the evenness of the ceiling, you need to find the lowest corner in the room and put a mark at the junction of the walls and ceiling. Using a building level, draw a straight line to the next corner and thus connect all the corners. Thanks to this manipulation, you can quickly determine the curvature of the base. If this parameter is less than a centimeter, then the ceiling must be leveled with starting putty. If the deviation is 1.5 -2 cm, then the base will have to be plastered before puttying. If the indicator exceeds 2 cm, then leveling the ceiling is only possible with plasterboard sheets.
Preparation of putty
Each type of putty mixture has its own proportions, so in order to properly prepare the composition, you must strictly follow the manufacturer’s instructions presented on the packaging. Ready polymer compositions They do not require pre-mixing, so they are ideal for those who are going to do their own repairs for the first time. But if you have a drill with a mixer attachment, you can save money and buy dry powder for mixing.
General principle Preparation of putty involves the following operations:
Putting the ceiling on your own is not the best easy job, which has to be carried out home handyman. Without certain skills, it will be very difficult to putty a ceiling for painting. It is because of this that this stage repair work owners prefer to trust professional repairmen.
But if you are not afraid of difficulties, it’s time to find out how to putty the ceiling yourself before painting. Even if you don’t have much knowledge in this area, you will still be able to cope - if you have the desire. In addition, thanks to this approach, you will save a lot of money from your family’s budget.
Tools and materials for work
Before you begin work, you should make sure that you have at hand all the tools and materials that will be necessary for puttying. If everything is prepared right away and is located in its place, you will not have to take time off from the work process, which will have a positive effect on the final result.
What may be required:
- How to putty a ceiling for painting without spatulas? Probably not. Therefore, you should have 1 narrow spatula (100 mm), at least 1 wide (from 300 to 400 mm);
- A metal half-ter (500 mm) must be available;
- To apply the primer, you will need a roller.
- You will also need a container to prepare the solution;
- A special construction mixer wouldn't hurt (if you don't have one, you don't have to go to the store and buy one - you can get by with a drill with an appropriate type of attachment). The drill attachment itself is cheap, but it will make the work process much easier for any owner;
- When choosing dry mixtures, it is imperative to look at all the recommendations that the manufacturer publishes on the packaging.
The cost of mixtures may vary, as well as the method of their preparation. Putty is usually used when it is necessary to smooth out minor differences (up to 0.5 cm) on the surface. If your ceiling has more variations, it is better to plaster it.
Preliminary stage
As part of this stage, the ceiling surface should be thoroughly cleaned and also prepared for all subsequent procedures.
If on your surface ceiling tiles were installed evenly, just remove the remaining wallpaper glue with it, the wallpaper itself, if there is whitewash there, wash it away.
A sponge is perfect for this type of work—you just need to thoroughly moisten it in water. When the whitewash layer or wallpaper is well saturated with moisture, they can be easily removed with an ordinary spatula.
Additional Tips:
- There is no need to immediately wet large areas of the surface - they dry quickly and you simply will not be able to reach them;
- The work is best done gradually. We wetted a small area and cleaned it. It’s enough to work on 1 at a time square meter ceiling;
- It is better to choose a primer with deep penetration - so that the putty adheres more effectively to the main ceiling surface. It is recommended to apply it in two layers, with one layer being perpendicular to the other;
- The application of the primer should be carried out evenly - marks of the roller, brush, drips: all this should not remain. If you are working with a brush, you need to hold it so that there is an angle of 55-65 degrees relative to the ceiling. During operation, the brush is also rotated around its axis evenly so that the tool wears evenly on all sides;
- It is much more convenient to work with a roller if the tool has short pile. It is best to apply the primer to the surface without pressing hard on the tool - it will be much more convenient.
Before starting puttying, it is recommended to plaster all large differences in the ceiling. When the plaster dries, it will need to be primed.
How to putty a ceiling
Now let's look at the putty process itself. Below instructions are provided, which reveals in detail all the features of the work.
Namely:
- First you need to prepare the mixture for work. To do this, pour into the water required quantity dry powder. For stirring, it is recommended to use a special construction mixer (if you don’t have one, use a drill with a suitable attachment pre-installed on it). Such care is needed in order to ready solution there were no lumps;
- The dry mixture is added to the water gradually - as a result, you should get a solution whose consistency is similar to thick sour cream. If this happens, then this part of the work is guaranteed to be done correctly;
- Now apply putty to the ceiling. This type of putty is exactly the same as all others, there are difficulties - but it’s all about natural conditions.
- Use a small spatula to take a small amount of mixtures. Distribute it evenly over the surface of the ceiling - a wide spatula will help you with this. The main thing is to apply the mixture to the surface so that a thin, uniform layer is obtained;
- All excess solution should be removed - a narrow spatula will help you with this. Place in the container where the solution was mixed;
- The procedure must be continued until the first layer of putty is applied to the entire ceiling surface;
- Wait until the first layer dries. Now you will need to get rid of all the irregularities (and they will definitely be on the ceiling). To remove sagging, sandpaper, a spatula are used, some people prefer to use a sanding mesh;
- Dust from the first layer will also need to be removed in any case. It’s just that dust can seriously affect the quality of all subsequent layers (not at all for the better).
To smooth out certain defects, use a wide spatula. When plastering the ceiling for painting, this tool is your indispensable assistant in this regard.
How to putty a ceiling for painting - we invite you to watch the video. The video tutorial will help you understand the material clearly, and beginners will quickly understand exactly how to work.
Additional Tips:
- The more unevenness there is on your ceiling, the more layers of putty you need to make. After each, they work to level the ceiling surface horizontally. Especially for this purpose, more mixture is placed on large irregularities. All subsequent layers are applied only when the previous ones have dried;
- The peculiarity of the finishing layer when puttingtying a ceiling for painting is that it should be thinner than the rest. It should be applied quickly so that the mixture on the edges does not have time to dry out. For this work, use a wide spatula, which is pressed against the ceiling with force. And all subsequent movements are made in order to remove everything unnecessary.
- When working this way, the tool must be perpendicular to the surface. If you do the job correctly, you may not even have to sand the ceiling;
- When finishing for painting, fine-grained sandpaper is usually used. It is with the help of this attribute that you can get a perfectly smooth surface. When the putty has dried, you need to highlight the surface - this way you can detect all the irregularities on your ceiling. That is, a carrying lamp will come in handy here.
You can refuse manual grinding - mechanically such work is done much faster. A sanding machine will help you here.
The nuances of puttying the ceiling for painting
When the surface of your ceiling has become smooth and even, you can start painting it - we discussed in detail above how to putty a ceiling for painting.
But when painting, one difficulty may arise, namely: during work, elements of the putty may stick to your roller. Of course, they will come off the ceiling - because of this, unevenness and defects will be created on its surface.
If it so happens that the putty came away from the ceiling during painting, there is no need to glue it back in place! Due to such actions, the condition of the surface will only further deteriorate. You need to protect yourself from such unpleasant features in advance.
What needs to be done so that such troubles did not happen to your surface:
- For finishing it is recommended to use putty, which is water resistant. This substance will definitely not get wet from water (as we remember, water is contained in the paint), the putty will adhere to the ceiling very reliably;
- If you use regular putty, just add a water-repellent primer to it. This primer should first be diluted in water - even before you prepare the putty solution;
- It is recommended to stir this mixture from time to time with a construction mixer - then it will not harden and lumps will not form in it. The validity period of such a composition is no more than three hours, then it can no longer be used in work;
- You can coat the finished ceiling with a moisture-resistant primer - right before applying paint to it;
- When painting a surface, you do not need to press the roller with force; you should also not drive this tool over one place for a long time - these simple tips will help you avoid serious difficulties.
Preparing drywall for painting
If your ceiling is finished with plasterboard sheets, you do not need to level the surface before puttingtying the ceiling for painting. Putty is applied to such a surface to ensure that the surface is uniformly smooth.
- It is imperative to align the joints between the plasterboard boards. It is best to chamfer them at an angle of 45 degrees before working on them. Then you need to perform priming. This will help remove all dust from the surface;
- Seams are also usually reinforced - for such work, perforated paper tape or a mesh made of fiberglass is chosen;
- Putty is applied to the joint using a narrow spatula - after this the substance is immediately leveled with a wide tool;
- When the heads of the self-tapping screws are puttied, they do it crosswise. After the seams have dried, they will need to be sanded. Next, you can prime the entire ceiling and apply finishing layer putties.

As part of this article, we talked in detail about how to putty a ceiling for painting. There is also a video in our material on this topic, as well as a detailed one, step by step description all the work that the master must perform. We wish you a successful renovation!
On the painted surface, the smallest flaws and defects are clearly visible. Therefore, before painting work The ceiling should be puttied before painting. To carry out this task efficiently not an easy task, it is necessary to understand all its subtleties and nuances.
Choosing putty for the ceiling
The choice of putty directly depends on the type and condition of the surface being treated. In our case we're talking about about the ceiling, so let’s take a closer look at what kind of ceiling putty for painting is used when repair and finishing works.
Depending on the component composition, functional properties and intended purpose, all putty mixtures are divided into rough (starting) and finishing:
- Starting putty. It is used to eliminate gross defects and flaws on the base - leveling significant differences, sealing large cracks and splits, filling large voids. Thanks to astringent properties using the starting mixture, the rough coating is smooth and resistant to deformation and the occurrence of shrinkage cracks.
- Finishing putty. Designed for fixing the rough layer and correcting minor errors on the starting putty coating. These may be the boundaries of cross strokes, shallow chips and gouges, thin furrows from small specks. With proper use of the finishing fine mixture, the ceiling becomes impeccably smooth and even.
Do-it-yourself puttying of the ceiling for painting
The technology of ceiling putty for painting consists of several stages. They are all interconnected, so they must be performed in a certain order.
Preparatory work before plastering the ceiling for painting
At the initial stage of work, you should prepare the base surface for subsequent puttying as thoroughly as possible, for this:
- The ceiling is cleared of residues old decoration- wallpaper, traces adhesive mixtures, whitewashing and paintwork.
- Noticeable protrusions and sagging on concrete base knocked down with a puncher, hammer or trojan.
- Cracks with a depth of more than 5-6 mm are expanded and sealed with coarse plaster.
- Mold stains are scraped off using a spatula or a metal brush, and special antiseptic impregnations are applied to the areas cleared of lesions.
Apply the primer to the ceiling in 2-3 layers with an interval of 30-40 minutes. It is most convenient to carry out this work using a paint brush or terry roller. Narrow brushes can be used to process joints and corners.
Preparing a putty mixture for the ceiling
It is most convenient to dilute powder mixtures for ceiling putty using a handy power tool. This can be a construction mixer or a universal drill with a stirrer attachment.
The putty is mixed according to the following scheme:
- First of all, pour the required amount into a clean container. warm water, then add a portion of the powder mixture.
- Mix the putty at low speed. Recommended tool speed is within 500-600 rpm. When mixing the components at higher speeds, the solution becomes oversaturated with oxygen, gives noticeable shrinkage after drying and becomes covered with microcracks.
- After initial mixing, the mixture should sit for 7-10 minutes. Then a control batch is performed. Properly diluted putty will have a uniform viscous consistency.
- First, pour the required amount of powder into a dry container, then add warm water little by little.
- During the mixing process, the putty mass is vigorously kneaded until a homogeneous plastic solution is formed.
- The finished putty is allowed to “rest” a little and mixed thoroughly again.
- When determining the proportions of water and dry powder for preparing putty, follow the manufacturer's recommendations.
- It is better to mix the putty mixture in small portions. Ideally, one batch should be enough for half an hour of work. Dried putty loses its elasticity and becomes unsuitable for subsequent use.
- After each mixing, thoroughly clean the work equipment from traces of putty mass. The preparation of a new batch of putty should be carried out in a clean container using clean tools.
Rough puttying of the ceiling before painting
Then you can move on to the main stage of work - applying the starting putty. To complete this process, you will need two spatulas - with a wide and a narrow blade. The first is considered the main tool, used for puttying the central part ceiling surface, the second - auxiliary, used for processing corners and other hard-to-reach areas.
Let's take a closer look at how to putty a ceiling for painting:
- You should start putting putty on the ceiling from one of the corners of the room.
- First, use a narrow spatula to take a small amount of the prepared solution and apply it evenly onto a wide canvas.
- Next, the main spatula is placed at an angle of 15-20 degrees to work surface and smoothly distribute the collected putty over it. The permissible thickness of the first starting layer is no more than 5-6 mm.
- All strokes must be crossed and made under the same pressure on the working tool. Thus, the entire area of the ceiling is covered with the putty mixture.
- The dried putty surface must be treated with a hand sander or sandpaper (for convenience, the latter can be attached to wooden block).
- If necessary, it is allowed to re-apply the starting putty over the sanded first rough coat. In this case, each subsequent layer should be thinner than the previous one.
Note! It is important that the mixture for starting putty is compatible with the “native” material ceiling: for example, a mixture for leveling a concrete surface is not recommended for puttying plasterboard sheets, etc.
Finishing putty on the ceiling for painting
As practice shows, finishing putty must be carried out without fail. If the task of the rough layer is to hide the visible errors of the working base, then the “finish” is designed to give it ideal smoothness and prepare it for final finishing.
Subtleties of finishing ceiling putty for painting:
- You can begin applying the finish only after the final drying of the rough (starting) coating.
- It is recommended to apply the finishing putty in a continuous layer, with the permissible variable thickness of the latter varying between 1-3 mm.
- As with the starting solution, use two types of paint spatulas - a wide one and a narrow one.
- As you work, be sure to change the direction of applying the putty mixture relative to the previous layer.
- It is important to apply the leveling solution to the ceiling as quickly and accurately as possible, then finishing coat It will turn out thin and even.
Sanding the ceiling before applying paint
After the last layer of putty has completely dried, the ceiling is thoroughly sanded. To do this, it is alternately sanded with medium and fine-grained sandpaper. This procedure will help remove the smallest roughness and scratches from the finishing putty coating.
At the end of the work, the ceiling is cleaned of dust deposits using a household vacuum cleaner and impregnated with a primer. It will strengthen and prepare the base for subsequent paint application.
Note! The sanding process is inevitably accompanied by the formation of a large amount of dust. That is why all grinding work should be performed in special equipment - safety glasses and a gauze respirator mask.
Plasterboard ceiling putty for painting
Plasterboard dropped ceilings are also subject to mandatory preparation before painting work. In general, puttying of plasterboard ceilings for painting is carried out according to standard technology. The only thing is that the layer of mortar can and should be made as thin as possible, since a surface of this type does not need serious leveling.
The procedure for puttingtying a plasterboard ceiling is as follows:
- First of all, you should check how well the screws are fixed in the plasterboard sheet. The protruding “caps” of loose fasteners will cling to the spatula and interfere with puttying work.
- Then you need to carefully deepen the seams between the sheets. For this purpose, docking end edges The gypsum board is cut with a sharp painting knife to 1/2 the depth of the sheet. The tilt angle of the tool is 45 degrees.
- Next, the entire area of the suspended ceiling structure, including inter-sheet seams and places where screws are attached, is coated with primer impregnation for drywall using a thick-bristled brush.
- Then they begin the actual puttying procedure. All compensation gaps between the sheets are filled with the starting solution, and a reinforcing bandage tape is fixed on top of the putty layer. For reliability, the latter is covered with another layer of putty mixture. The “hats” of the fasteners are masked with cross strokes.
- After drying, the puttyed loose areas are cleaned until smooth using grinding machine or graters of various grain sizes and again coated with a primer composition. The finishing touch of the work is to apply a thin layer of finishing putty over the entire area of the plasterboard.
Note! When puttingtying a plasterboard ceiling, it is important to prevent the formation of transitions and “steps” between the treated and untreated sections of the structure. The consumption of the solution and the thickness of the correction layers in this case should be minimal.

Puttying the ceiling for painting with your own hands is a meticulous process that requires accuracy, attentiveness and knowledge of some nuances. To achieve the desired result, use during work quality materials and strictly follow the puttying technology described above.
Sometimes the question arises: who should I trust to renovate my apartment? I would like to immediately invite a team of qualified craftsmen. They can do it. They have practice. But on various reasons it is not always possible to do this.
What if you take a spatula and paint brush yourself? And start the repair from the ceiling, namely by puttingtying the ceiling for painting with your own hands. This task requires skill, so first you need to study the question of how to putty the ceiling for painting yourself.
When planning repair or finishing work, the first thing you should pay attention to is the ceiling. Is it good enough to paint? Do I need to putty the ceiling before painting?
Often the slabs lie unevenly on the ceiling. Then first you need to try to get rid of this defect plastering the ceiling.
In addition, on its surface you can find a lot of irregularities, cracks, and depressions. And then you simply cannot do without ceiling putty for painting yourself.
What does it take to get work going?
Tools
For ease of puttying before painting, you need to prepare all the necessary equipment:
- spatulas of different sizes;
- roller;
- half;
- dishes for preparing the mixture;
- device for good mixing of the mixture.
Mixtures
Before you putty the ceiling for painting with your own hands, you need to figure out what is the best way to do it.
For high-quality ceiling putty for painting, it is important choose correctly putty mixture . Putty is a mixture intended for leveling any surface. Her the choice depends on the material what the ceiling is made of: wood, concrete or plasterboard.
Each material requires its own type of mixture. Available for sale dry mixes(they must be diluted with water before use) and ready-made mixtures (ready to use), which are sold in plastic buckets. The latter are higher in price, but of better quality.
You must first decide what type of putty is needed for the job. Distinguish three types of putty for the ceiling. Which one to choose:
- starting;
- finishing;
- universal.
Starting mixtures used to fill cracks and level out distortions. Finishing putty The ceiling for painting gives the surface an unusual shine and completes the work of putty. Universal mixtures work in the intervals between the initial and final stages.
Types of putties by composition
Putty mixtures are divided into groups according to composition:
- mixtures cement based. They have excellent resistance to moisture. They are recommended to putty the ceiling in the kitchen and bathroom;
- gypsum mixtures suitable for leveling ceilings in rooms and corridors;
- polymer putty not bad for rooms and corridors, but has a longer drying period, but is more convenient to apply than others and gives the ceiling a smooth effect better than other mixtures.
Technology of ceiling putty for painting
Do-it-yourself puttying of the ceiling for painting includes several stages.
Preparing the ceiling surface
It doesn’t matter who you are making the repairs after: builders or just getting ready for cosmetic repairs - in any case, if you intend to have a high-quality completed repair, you need to do the ceiling. How to properly putty a ceiling for painting:
- The first thing to do is remove all interference: old wallpaper, glue, whitewash. To do this, we wet the surface (it’s more convenient to do this with a sprayer), wait for a while, and then remove all roughness with a spatula. It's better to act this way small areas(1 m by 1 m), otherwise the ceiling will have time to dry before you start removing all unnecessary things from it.
- Next, for high-quality adhesion of the putty to the ceiling, you need to apply it to it. primer. Apply it in two layers. We place the first one parallel to the wall where the window is located, and the second one – perpendicular to the first one. The primer must be applied smoothly, without smudges. The most suitable tool For this purpose, use a roller with short fur. If the ceiling has recesses, you will have to work with a brush.
How to properly putty a ceiling for painting
Puttying the ceiling with your own hands before painting is not an easy job. Its result largely depends on what kind of putty should be chosen for the ceiling.
For rooms with high humidity need to choose waterproof mixtures. In this case, you need to choose the appropriate paint - water-repellent. Otherwise, after the repair, there will come a time when the paint begins to crumble along with the putty.
To the rooms with high humidity include kitchen and bathrooms. This means that to the question of how to putty the ceiling in a bathroom before painting, the answer is obvious - waterproof putty.
To the rooms with moderate humidity An ordinary putty containing gypsum and cement is suitable. However, it must be remembered that such a mixture is difficult to place on the ceiling.
Standard putty has the designation KR, marking LR+ suggests that this material can be used in wet areas. When choosing a ceiling putty for painting, study the manufacturer's advice and choose which one is best for you.
It’s good if they are prepared for work right away home page And finishing putty. You'll need both. It is better to take a dry mixture and prepare a solution as needed. Know how to calculate how much material you will need to work in a certain area. Unused mixture will quickly harden and become unusable.
After priming, we begin putty. How to level a ceiling with putty before painting? What are the nuances here? We remember that last layer primer is placed perpendicular to the window. This means that the first layer of starting putty must be applied parallel to the wall with the window.
Using a small spatula, apply the mixture evenly onto a large spatula. Then big tool Apply the putty to the wall as thinly and evenly as possible. The thickness of the layer can be adjusted by the angle of the spatula relative to the ceiling: larger angle - thinner layer. We remove the remaining material from the large putty with a small tool and throw it into a bowl. The entire ceiling is processed in this way.
Important! Special attention you need to pay attention to the corners: they immediately catch your eye. Therefore, it is better to start work from the corners, and after completing the putty, carefully inspect them again.
After the first layer has dried, you should remove all roughness. For this you can use large sandpaper . After this work, a lot of dust will remain on the ceiling, which can affect the quality finished work. Therefore, this dust should be removed or used with a spatula.
It's time to apply second layer of putty. It is placed perpendicular to the first. The question may arise: how many times to putty the ceiling? It depends on the degree of unevenness of the ceiling. The more irregularities, the more layers. Work continues until the ceiling takes on its ideal appearance. This is very easy to check: hold a flashlight to the ceiling and you will see irregularities.
Advice. When putting putty on the ceiling, you must strive to level it horizontally. In uneven areas, more mixture is applied. The next layer of putty is applied after the previous layer has dried.
So that the ceiling does not disappoint you after repairs, after working with starting putty need to go again primer. Now you can take on the finishing putty. Its layer should be the thinnest. It should be applied quickly, avoiding the mixture drying out around the edges. Place the solution on the ceiling with a wide spatula and immediately remove the remaining solution from the surface, pressing the spatula forcefully against the ceiling.
Wanting to get thin layer, you need to hold the spatula practically perpendicular to the surface. If you received flat ceiling, then there is no need to sand it. But if you plan to paint the ceiling, you will still have to sand it down with fine sandpaper. What if the ceiling is made of plasterboard? How to properly putty a plasterboard ceiling for painting?
Do-it-yourself plasterboard ceiling putty for painting
Do-it-yourself puttying of a plasterboard ceiling for painting has a number of features: after all, the canvas itself is already smooth and does not need leveling. Therefore, you will have to work here with seams and screw heads.
As a rule, the edges of the plasterboard sheets already have an oblique cut. If this is not the case, then you will have to prepare the canvas yourself: cut sharp knife 45® chamfer. After the drywall is fixed to the ceiling, the joints and seams must be primed in order to cover them with a special fiberglass mesh, which has a self-adhesive backing. This work will not be difficult.
Then apply the mixture with a narrow spatula, trying to fill the seam as much as possible, and level it with a wide tool. We putty the screw caps crosswise. This allows you to completely fill all the grooves of the screws. We wait for the putty to dry and sand it and apply it to a primer, for which we choose an acrylic-based primer. It doesn't take long to dry. Now we apply finishing putty all over the ceiling to give the ceiling an overall smoothness.
What putty to putty on a plasterboard ceiling for painting
If plasterboard ceiling is being prepared for painting, it is better to use polymer putties, which have a fine grain size. This allows you to achieve the most even surface possible.
Ceiling putty under water-based paint does not have any special features. Any fine-grained material is suitable for the job. gypsum putty. The leading manufacturers of putty materials are KNAUF, VETONIT, CERESITE, ATLAS.
How to avoid trouble later
To ensure that repairs do not have to be resumed after some time, you need to observe some nuances:
- As finishing putty need to use waterproof material, otherwise, when applying paint (which contains water), the putty will spread. You can do it differently: add a water-repellent primer to regular putty. It should be taken into account that the primer is first diluted in water, only then added to the mixture.
- In order to give the putty special strength, coat the surface well before applying it to the ceiling. waterproof primer.
- When painting the ceiling, do not press too hard on the roller and do not swipe over the same place several times.
Plastering a ceiling for painting is a job that requires patience, hard work and good investment. It will require time and effort. Haste and stinginess will be unnecessary here. If the ceiling putty is done in compliance with all requirements, then at the end you will get perfectly flat ceiling, ready for painting.
