Even if you have never been engaged in repair matters, there is nothing difficult in this - you need to simply be patient and familiar with the rules for the preparation of walls. Why is it so important to do this requirement? Since the end result, we expect to see excellent, that is, smooth walls without tubercles protrusions, with perfect joints, then all draft work must be accomplished responsibly. The optimal option is the use of the so-called multistage method. First, you need to put the walls of the walls under the wallpaper, then plastering the surface, apply a layer of primer and after complete drying to deteriorate all irregularities. Okuring - the so-called the last preparatory stage of the walls under the wallpaper, but since it is considered very laborious and dusty, then this can be avoided.
Of course, wall deals with wallpaper are currently very different from Soviet methods. Previously, the wallpaper was glued directly on the concrete wall, and instead of the primer, it was customary to use newspapers. Imagine, you first needed to leave the walls with old newspapers and only then begin to the final stage of repair. By the way, the whole of Soviet women boiled themselves. We do not need it, because our task is to prepare walls under the shocking of wallpaper.
How to prepare walls under the wallpaper
If the walls are painted paint, the remains of old wallpaper remained on them, then it is necessary to approach the surface preparation individually. Let's first learn how to prepare the walls in the new building.
The easiest thing is to stick the wallpaper for new walls, but here there are certain difficulties in the arrangement of housing. For example, as soon as you get an apartment in a new house and get inside the future dwellings, concrete floors are confused, crooked sockets and uneven walls. Naturally, to bring everything in order as you would like to try to try. Quickly paste wallpaper on the walls will not succeed, so we will act in stages.
Where to start:
- Apply a special liquid solution on the wall (it is called "spray"). Layer thickness - ranging from 3 to 10 mm. Consistency of the solution - like mayonnaise, to fill all the depressions of the new wall. The subsequent stages will depend on the solution density.
- Treatment of primer. If necessary, then the solution can be applied several times, and with the interval, so that the primer is well absorbed.
- One of the subsequent stages of the preparation of walls under the sticking of wallpapers is the applying layer. That is, it is necessary to apply a thin layer of plaster (from 2 to 4 mm) to smooth out irregularities.
- The final stage is grinding the walls after complete drying of putty. This part of the work is performed using small emery paper and a special device. Since the work is very laborious and dusty, you can periodically make the surface of the sprayer (only not too abundant). It is advisable to open windows, since all the dust will sow on the floor and the ceiling.
To work, we will need:
- primer;
- starting and finishing putty;
- 2 spatula;
- rubber spatula;
- bowl for kneading a solution (you can buy a finished putty in buckets);
- roller for applying primer;
- sandpaper.
At first glance, the newcomers may seem like difficulty, but in fact everything is not so difficult, as it seems. It is much more difficult to prepare old walls.
Preparation of walls under the wallpaper with your own hands
How to remove the wallpaper
Most people have to cross the wallpaper in their dwellings several times in life. Many already get old apartments with wallpaper on the walls. Naturally, they need to get rid of them. For you, this procedure will seem boring, but it is better to try to gain patience and still get rid of old wallpapers than stick new on top. It can be fraught with what you will have to reassure all the work, because as soon as the glue falls on the surface, they will be splashing and will soon disappear.
Prepare first everything is necessary, then not to be distracted in search of the desired subject:
- medium spatula;
- spray;
- foam roller;
- conventional water;
- vinegar.
So, in order to quickly and easily remove old wallpaper from the walls, you need to familiarize yourself with these recommendations:
- Simplify the task, respectively and save precious time in the preparation of walls, it is possible if you pre-moisten the surface. To do this, use the pulverizer, only fill the container not with cold water, but hot. By the way, it is possible to moisten the old wallpaper and the usual roller, just make sure that the water did not sprinkle on the sides during operation. To protect the floor from moisture from entering, thinking out and this moment - parquet and linoleum can be made with a construction film, and the edges secure with paper scotch.
- Remember that, near the batteries and under the windows, the wallpaper always keeps stronger than on the walls. In order to remove the wallpaper in these places, you will need more patience and time. Do not try to remove the paper with your hands, better use the spatula. You can add several spoons of vinegar or other means that solubles glue.
- Remember, if you wet the wall, then electricity in the room must be de-energized. Water can get on the wires, and this is already dangerous for a person.
- After moisturizing the walls, wait 3-5 minutes and only then carefully, with a spatula, remove the wallpaper.
On the purified surface you need to apply a layer of primer for walls under the wallpaper. After it is absorbed, irregular sections can be sharpened. Next, you need to wait for a complete drying of the solution and again apply a layer of primer, after which you can begin to stick wallpaper.
How to prepare a painted wall
Stick the wallpaper for a previously painted wall is very difficult. It holds the wallpaper on slippery surfaces is very bad, so it is necessary to get rid of the layer of paint and only then start work. This is very laborious work, since the paint is very difficult lagging behind the surface. What just do not try to come up with people to remove paint from the walls.
Let's get acquainted with the most efficient ways:
- you can sand the surface and make a few notches in the wall, and then glue the wallpaper. Perhaps this option will be rapidly, but it is unknown, as after such preparations on the walls, wallpapers will be held;
- painting processing layer of primer. It is useless, because wallpapers can be laid, but how much they will last, no one guarantees. With the slightest temperature fluctuations and enhance humidity, they can fall behind the wall;
- warming paint with a construction dryer. This method is effective, but not harmless. The paint heats up and becomes soft, it is easy to remove with a spatula with a wall, but at the same time it highlights harmful pairs, unsafe for human health. If you choose this method of preparing the wall under painting, then you need to open the windows so as not to poison chemical pairs;
- paint removal using grinders - the method is effective, but very dusty. You need to close all the slots and doors, otherwise there will be a lot of dust in the neighboring rooms;
- the use of a special solution - the wash must be applied to the entire surface of the wall, and when it softens, remove the spatula. Be careful: Carry the room, put on protection.
If it is impossible to clean the wall from the paint, then you can take the primer "Concrete contact" or wallpaper glue. But then ensure that the wallpaper will stay for a long time, even experienced builders cannot.
When you remove the old paint from the surface, it is necessary to align the walls under the wallpaper. To do this, first cleaned the surface, then the primer mixture is applied and only after that you can begin to put the walls under the wallpaper with your own hands. This is an important and responsible step of surface preparation, so work needs to be performed correctly and efficiently.
How to put the walls under the wallpaper
Using a putty, you can align the shallow cracks (up to 5 mm). Works are performed at a temperature from +10 to +30 oC, air humidity - no higher than 50%.
To prepare walls under the wallpaper, you can buy a ready-made universal putty. It is sold in small tanks. Its cost is more expensive than the price of a dry mixture, but you do not have to look for a building mixer and a container to properly prepare the solution. Each type of building material has its drawbacks and advantages. For example, a dry mixture is stored for a long time, and a finished putty after you remove the cover, you need to immediately use.
Since the finished putty gives a shrinkage, it cannot be applied with a thick layer. Make sure that the surface is clean and dry. Before proceeding with the works, heating the walls with primer, this will improve the grip of the solution with the surface.
How to apply putty:
- Works on the preparation of walls can be divided into 2 stages: first is applied with a layer of starting putty (it is larger), and then with a thin layer (after drying), put the finish putty (fine-grained).
- If you are not fundamentally important, you can immediately shut the walls of the starting putty. Use a wide spatula to work. It is necessary to put a little putty on a thin blade (a narrow spatula) and spend a wide construction tool on the wall. Movement - top-down. After the layer is evenly distributed, you can continue to work.
- If your wall is porous, then you can easily facilitate the task and apply putting on a special grid. To do this, we will have to put the wall completely, but the mixture will go well, and the wall itself will become smooth and its strength will improve.
- Applying a putty on the wall, keep the spatula at an angle of 30 o. You will help to avoid bugs and drops. This advice will help you: overlap the previous layer new, smoothing the splines by the spatula.
- To make a beautiful smooth angle, you need to use an angular spatula. First, you need an auxiliary spatula (small) to put a putty to an angle or slope, and then disperse it with an angular spatula. During the day, the layer of putty must dry.
- When the starting putty dries, it will be possible to apply a layer of finishing putty. After 12 hours, the wall can be projected, and after 2 days, when the walls are completely dry, it is time to get to the woven salary.
Preparation of plasterboard walls under the wallpaper
Place the walls under the wallpaper is only necessary if they are not very curves. If the differences are large, it is best to align them with the help of plasterboard. Preparation of walls under the sticking of wallpaper will give you pleasure because the work is not dusty and not heavy:
- First you need to progress the surface. Wait when the primer dries (from 8 to 24 hours).
- The location of the two sheets of plasterboard are punctured by a special ribbon (sherryanka), and then apply a thin layer of putty.
- Now you can apply a thin layer of putty and, after drying, walk along the surface first with a large sandpaper, and then shallow. So you can achieve smoothness.
- Now it remains to apply another 1 layer of primer and wait again until it is absorbed. You can start the wallpaper to stick only when the walls are absolutely dry. If you are not sure about this, you can do a test: glue a small piece of polyethylene to the tape. In the morning you can see the result: if the polyethylene remains dry, it means that the wall is dry and can be glued. If water droplets appeared on the inside, then you need to dry the surface.
Remember that glue wallpaper directly to the cardboard is prohibited, so you will spoil all the finishing material. Wallpaper will be kept, but with the slightest mechanical effects in the wall will be dents, and they will not disappear, because it is impossible to remove wallpaper from the wall.
Humidity, smoothness and strength - these requirements must be observed. If the wall is poured, then the wallpaper will begin to lag behind the wall.
