Drywall is one of the favorite materials of builders, including beginners. Nevertheless, the puttying of the ceiling is the process that causes the greatest difficulties, and during which, as a rule, they turn to specialists. However, you can do this work yourself if you pay enough attention to every detail. How exactly - we will tell in our today's article.
Do-it-yourself ceiling putty: preliminary preparation
Finishing the ceiling can occur in different ways, depending on what condition the room was in before the repair. If it is completely new, then you just need to prime the coating so that the putty is more properly laid and last longer in its place.
If the apartment has already been renovated, it will be necessary to remove everything, down to concrete. You will also need to get rid of layers of paint and wallpaper. Only then can we begin to level the surface. What is the purpose of this work? This is necessary so that any material normally lies on the surface, and it does not look sloppy. In addition, the primed surface does not absorb moisture and this prolongs its service life. After priming, putty is also better and dries faster. This reduces repair time.
What is the best primer?
This work is carried out in several stages:
- The choice of the suitable material for the primer is made (depending on the material chosen for covering the ceiling).
- The primer must be poured into a convenient container, and then begin to be applied to the ceiling. It is most convenient to do this with a terry roller, which will allow you to cope with the task, even standing on the floor.
- Then you can go directly to the putty.
We process drywall
How to deal with him? Putty on the ceiling, when it comes to drywall, should occur with the coating of all seams, holes and even screws.
The mixture must be prepared immediately before application by diluting a small amount of the powder in water. It is important to note that you need to cook only such an amount of the mixture that you can put on the ceiling in a fairly short period of time.
The consistency of the resulting solution should resemble thick sour cream, but you can get it by mixing manually or using a drill with a special nozzle.
Please note that the putty of the ceiling should occur exclusively in a thin layer and in stages. Otherwise, the material will crack and begin to fall off. After drying of the previous layer it is possible to put one more.
First stage
How to putty the ceiling for painting with your own hands? You need to start by preparing the right mixture. In addition to the type of thick sour cream, the readiness can be determined as follows: put the spatula upright and check how the mixture behaves. If she did not begin to slide, then it can be used for work.
Stage 2
Using the resulting solution, we coat the joints. First you need to move the spatula across, and then along the gaps. If roughness has formed during the coating of the ceiling or walls, they must be removed by sanding.
It can be noted that the processing of the gypsum board ceiling does not have fundamental differences from the finish of any other coating.
Stage 3
Correct puttying of the ceiling should include the finishing. You can’t do without it. This stage is important only when plastering the ceiling from plasterboard for painting. After all, if the work is done under the wallpaper, then, as a rule, only the starting finish is used.
The mixture and its consistency here should not differ from the starting finish. Putty is applied to all places where joints are still visible. We need to completely eliminate their presence. After necessarily grinding the surface (ceiling or walls sheathed with drywall).
Features
Consider the features of puttying and painting the ceiling of gypsum board. Are there any nuances in this work? Puttying the gypsum plasterboard ceiling with your own hands has a number of features that you need to know about before proceeding with the repair work.
The main feature is that it is not really necessary to level the surface of the drywall - you just need to smooth out all the joints between its sheets. For this, a primer is preliminarily made, which helps to get rid of dust in the spaces between the sheets.
All seams and joints should be additionally glued with fiberglass mesh. To apply it is not difficult, because it has a self-adhesive base.
What next?
How to do the painting of the ceiling with putty yourself next? After the ceiling has already been successfully coated with mortar, and the surface looks perfectly flat, many are faced with a new problem. When they begin to paint the ceiling, pieces of material begin to stick to the platen and at the same time create gaps in the ceiling. Thus, the ideal surface is destroyed. But what causes this?
The thing is that for finishing it is strongly recommended to use waterproof putty. If you have already purchased ordinary putty, you can add a waterproof primer to it. Experts say that it will help get rid of the problem.
It will not be superfluous and just additionally cover the ceiling with a waterproof primer, which will help the paint in future to lie better on the surface.
In the process of painting itself, it is strongly not recommended that you press the roller with great force or drive it several times in the same place. It is necessary to be as careful as possible and not to allow the surface to get too wet to prevent peeling of the material.
Ceiling Painting Steps
After puttying, the ceiling is recommended to be additionally sanded. Of course, experienced craftsmen can do the job so that no sanding is needed, but these are rare cases. It is better to sand the ceiling yourself or do it with an electric grater. During this process, it is worth arming yourself with a respirator and a protective mask. After all, any materials that will fall off the ceiling at this moment can cause severe harm to the respiratory tract.
The next step is to clean the ceiling from dust and various residues of the material. To do this with just one cleaning will not work, and therefore you need to make a second primer. It is absolutely not worth saving on this. Otherwise, the enamel will slide into lumps and simply will not lie on the surface.
Before painting, you must make sure that the surface is hard and absolutely smooth. Otherwise, these defects cannot be eliminated later.
Painting tips
Experts recommend using a wool roller for these works. After all, during painting, he leaves behind a bubbly surface, which after drying becomes dull.
If you use a foam roller for work, this can lead to glare on the ceiling. As experience shows, these glare will look rather messy.
If you decide to paint the ceiling not white, but any other, you need to consider that the solution should be done only once. The second time you can’t get the same ratio of paint and solvent. This will lead to the fact that the entire ceiling will be in different shades.
Before starting the painting, it is also recommended to process the contact angle of the ceiling and the wall. Indeed, further work will be carried out exclusively by roller, and this step will help to avoid inaccuracy in the work process.
Painting should take place exclusively with water-based paint. It must first be placed in a special bath. You can do without one, but it helps to remove the remnants of the solution and leave them still in the tank.
After each time, when the roller is lowered into the paint, it must be carefully wrung out. This will help to prevent the appearance of drips on the ceiling and achieve uniform distribution of color on the surface.
As a rule, the ceiling should be covered only two times. However, this may depend on how the putty was made and whether all defects on it were eliminated. If there are greasy spots on the ceiling, they will have to be covered with paint. The maximum number of layers of enamel is five.
It is important to note that before applying the next layer, you must make sure that the previous one is accurately dried. This can be understood as darker spots of paint disappear from the ceiling.
If you begin to process the ceiling before the last layer dries, this will cause the enamel to mix and form unpleasant stains on the surface.
If you decide to mix several colors while covering the ceiling surface, use masking tape. It will help to evenly distribute the paint on the surface. Also, it is quite easy to remove - users say that it is most convenient to use, unlike a clerical tape.
conclusions
So, we found out how plasterboard plastering is correctly applied for painting. As you can see, this process is not easy. However, he can succumb even to a novice, if you make a sufficient amount of effort. It is important to pay attention to the nuances and in no case be in a hurry in the process of puttying, priming, sanding and even painting. It is necessary to let each coating layer dry and only then proceed to the next stage of repair.
Nevertheless, if you follow all the tips and pay attention to details, as well as do not neglect the extra layer of primer, putty or even the painting itself, the result will pleasantly surprise. It is important to achieve the maximum effect at each stage of preparation of the ceiling, so that later you do not have to improve all the nuances with extra layers of paint. A smooth surface is the only condition that needs to be controlled every time.
