Preparation of walls for painting: the order of work, features and recommendations

At one time, painted surfaces were associated with everyone with creepy curved walls, covered with a layer of gloomy shade of oil paint. Equally unpleasant, they looked both in the apartments and in the living quarters. The owners of the apartments tried to get rid of this "beauty" by any means, attaching wallpaper and foam to the dirty-green and poisonous-blue surfaces, and specially skilled ones simply stuffed them into the lining. Then, already in the early nineties, when in the stores unprecedented and unknown to the Soviet people building materials began to appear, a lot of people began to paint the walls with water-based paint of different colors. It was fashionable and prestigious, almost every second thought that only such a finish would make the interior of an apartment or house richer. However, such a question as the competent preparation of walls for painting with water-based paint was not specifically considered. And because the result was not always the way it was wanted. And gradually they began to refuse from this kind of finishing, especially as on the shelves of shops there appeared unprecedented vinyl and non-woven wallpaper of unusual beauty and outlandish colors. Strictly speaking, to this little excursion? And to the fact that at the moment the coloring again becomes popular. And already in a completely different form, since it is carried out using the latest materials and using modern technologies. And if in the room it is planned to carry out such kind of finishing works as painting of walls, surface preparation is the main and determining stage. And it is this process that will be devoted to the whole subsequent text. We will try to explain in as much detail as possible what the preparation of the walls for painting is. The order of work, all the nuances of their conduct and useful advice of specialists - about all this, read below.

Types of surfaces to be painted

So, what walls can be trimmed in this way? In principle, almost any. But, from a professional point of view, at the moment it is advisable to paint: plastered or well plastered surfaces, a base made of the material intended for this (wallpaper for painting, glass fibers, etc.), textured and relief plaster, drywall prepared by the corresponding Way.

Depending on which surface will be subject to the finish, and the preparation of the walls for painting. Some stages are characteristic for each type of work, and some in one or another case either do not apply at all, or are combined with each other.

The order of preparation of walls for painting

This, as a rule, is a step-by-step process. First you need to prepare the surface. Then align - or plaster, or plasterboard. After this, the finish is finished either with putty or decorative plaster. There is also such an option as a sticker on the already unsoldered walls of the wallpaper for painting or fiberglass. Both of these procedures also apply to finishing. Further - in detail about what is the preparation of the walls before painting in each case.

And we will start with the preparatory procedures, which, as a rule, are practically the same in all cases.

Preliminary work

Preparing walls for painting requires a very careful approach. And it is necessary to approach the issue with all responsibility, because the final result depends entirely on this. So, the walls must first of all be cleaned of old types of decoration. If this wallpaper, they need to be removed, and completely. If it's an oil paint and a water-based paint, you also have to get rid of it, not to mention whitewashing. After this, a thorough revision of the walls must be carried out. First of all, check their integrity. If they were previously plastered, the mortar layer is durable and holds well on the wall - excellent. If there are places where he literally walks - they need to be cleaned, and defects should be filled with fresh solution. If more than 40 percent of the surface is damaged, it is recommended not to waste time and completely remove all old plaster from the wall.

Once you find that you have a solid foundation as a result, you can proceed to its primer.

A small digression

An interesting feature of repair work is that sometimes the preparation process takes almost more time than the entire procedure of the subsequent finishing. Sometimes with some walls paper sheets have to be removed literally by millimeter, and what to say about how difficult is the procedure for removing oil paint. Therefore, before we continue the conversation about how to prepare the walls for painting after the preparatory stage, we want to bring a few tips from experienced masters. Perhaps they will help someone to cope with dirty and hard work.

How to clean the wallpaper

Never remove old wallpaper, unless, of course, they do not fall off the wall themselves, in a dry state. When the paper is firmly adhered to the plaster, it can sometimes be removed with the base itself. So arm yourself with a bucket of warm water and a brush (and not a roller!) And begin to moisten the wall. And not just once or twice, but literally almost every 15 minutes. Believe me, your hard work will be rewarded. At some point, the wallpaper will start to bubble and fall behind the wall. You will only have a little help in this.

How to get rid of paint

It is impractical to try to remove the paint from the wall with a small spatula. It is better to immediately take a drill with a nozzle designed specifically for these purposes, and work with this tool. The only thing you can try - is to remove an off-grade water-based paint with a sponge soaked in water. However, if you have to prepare large surfaces, you can imagine how many walls you have to wash.

Competent priming

Never apply, in spite of the advice of some, a primer with a roller. Most of it will be on the floor, which, by the way, will be hard enough then to cleanse of the dried out composition. Optimum option - a spray gun, at least portable. If it does not exist, use a brush. Only in this way you can really qualitatively prepare the base and ensure the penetration of the primer into its internal layers.

Next stage

If the original wall is flat, the plaster on it is preserved, the defects are sealed, you can proceed to the finish finish. What it will be - puttying or covering the surface with decorative plaster, - depends on the chosen type of work. In any case, even walls can already be prepared for painting. Another thing is if they are so crooked that it is almost impossible to cope with them. In this case, it is more expedient to pay attention to drywall. Align the surface with it you can easily and quickly. However, then it will also have to be prepared for coloring, but we'll talk about this below.

If you removed all the old plaster and you have a bare concrete or brick wall in front of you, you'll have to level it with a plaster solution using beacons. This is the most effective method, which allows you to get a truly flat surface.

If a drywall was chosen

We will not talk about how to mount the GKL on the walls. This is not our task. But to say a few words about what is the preparation of walls from gypsum board for painting, it is necessary. The thing is that directly on the GKL, neither the wallpaper nor the coloring composition is applied. They must necessarily be pre-ground, carefully cleaned and primed, and only then painted.

The process of puttying

Perhaps, this is the most complicated procedure that a master who prepares walls for painting should perform. The fact is that the surface should be not only smooth, but also ideally smooth. The slightest defect, the slightest scratch will be visible after the paint has dried. And to achieve this, the procedure should be carried out in two stages. First the first layer is applied. After it thoroughly dries, you should walk on it with a mesh or sandpaper to smooth out any irregularities. And after that, carefully primed and again wait for the drying. And only then apply a thin finish coat of putty, which completely closes the existing defects. In the same case, if some minor irregularities are present, they can be gently smoothed, then again clean out the entire surface and primed. Then after a day it is allowed to proceed to staining.

Nuances

If you are preparing the walls for the wallpaper for painting, then in this case, the ideal surface to seek does not make sense. Yes, it should be flat, smooth enough, but can have minor defects. The main thing is to get a really solid foundation. The very same wallpaper for painting, as a rule, always corrugated, and because all sorts of scratches just hide under them. The only rule that must be observed is that during the puttying it is not recommended to leave areas with a thin layer of putty through which the plaster renders through. Perform the entire process with the same thoroughness, which requires the preparation of walls for painting without wallpaper. You just can not fixate on minor defects. They will not be visible. Otherwise, there are no differences. Finishing putty is cleaned and covered with soil. After it dries, you can start to glue the wallpaper. Painting them is allowed no earlier than at least four days after pasting. Give them time to dry. Otherwise, as a result, under the influence of paint, they will begin to get wet and flake off the wall.

There is another question that can not be overlooked when it comes to how to prepare the walls for painting. This is the use of such material as fiberglass. Professionals call it a paint glass fiber. About him - further.

Fiberglass

What is it for? And in order to make the surface perfectly smooth and protect it from cracks. And then the walls covered with paint glass fiber will long please you with a magnificent appearance, as they are not afraid of any shrinkage and temperature changes, because all the defects appearing on the surface will be hidden under the fiberglass. By the way, the latter happens to be corrugated and thick enough, and quite thin, literally translucent canvas. It is also called spider web. It is this variety that enjoys the greatest popularity, because, firstly, such fiberglass costs literally a penny, and secondly, it is easier to work with it.

And a few words about the process itself. First the wall is shpakuetsya. It is enough to apply only one rough layer. Then it must be cleaned and primed. And paste the spider web on a special glue. You can take and composition for non-woven wallpaper. After drying, the fiberglass again shpakuetsya very thin layer, and this procedure is very simple and fast. After priming, you can paint the walls.

And about the textured plaster

If you prepare the walls for painting on decorative plaster, then such a procedure as shpaklevanie, is not required at all. The textured solution is applied directly to the prepared base, after drying it is primed, and then it is painted.
