Do you need to primed walls before gluing the wallpaper: preparation, process and material types

If you decide to use the services of professionals during the repair, they definitely will not have a question about whether you need to primed the walls before wallpapering . And in the absence of this composition in the range of construction materials you bought, they will certainly send you to the store for him. Moreover, the primer will literally pour into the river when preparing walls for pasting.

But home-based masters, self-repair workers, quite often omit this procedure, considering it optional. And, it should be noted, completely in vain. Why? Let's try to figure this out. So, do you need to primed the walls before wallpapering? And if so, why, how and what to do?

A few words about the process of pasting

Wallpapers have always been and still remain a popular material for decorating wall surfaces. Today they produce a huge number of all kinds of species, differing in value, and in texture, and in the materials from which they are made. However, there is only one thing that unites them: the walls for them must be properly prepared. And deeply mistaken are those house masters who think that the thicker the wallpaper, the less time it takes to pre-process the walls. It is necessary to remember: if you do not want the result of your works to cause only tears, do not try to save. Ideally, the walls must first be leveled with plaster, and then puttyed. Or as a minimum, carry out at least a second procedure. Only then you can count on the fact that the wallpaper will not only lie on the wall beautifully, but will last for a long time, and will not begin to fall apart at the seams and in the corners almost the day after the end of the repair work.

And you do not have to wonder whether you need to primed the walls before wallpapering, considering this procedure as not worthwhile and trying to speed up the process. Priming mixture should always be at hand, and it should be used when plastering, and when puttying, and before directly pasting. Why? Now we will explain. However, to make it easier for the home master to understand why the walls should be primed before wallpapering, you need to consider what the composition itself is.

Properties of the primer

Primer is called a special mixture containing substances that create a kind of film on the surface. Due to this, the base base absorbs the adhesive paste less and becomes more durable. In addition, the wall treated with the soil has high adhesive properties, as a result of which the materials deposited on it adhere better to the surface and last longer. As a rule, practically all mixtures contain in their composition special antibacterial substances, which, firstly, do not give rise to mold, and secondly, kill all living creatures, who love to settle under the same wallpaper.

As a result ...

If you do not waste time and do not puzzle over the question of whether you need to wall-paste walls after puttying before wall-papering, and have performed this procedure, you can deservedly expect that:

• Your wall has become stronger and now it definitely will not crumble.
• You coped with the dust on the wall, and it will not prevent the wallpaper from adhering to the surface.
• At the time of gluing, the wall will "hold" the glue well, and not absorb it with great speed. This means that the wallpaper will stick well and stay for a long time.
• Under them there will be no fungus, and also bugs, worms and other animals are not in control.
• The very procedure of pasting will pass quite comfortably: you do not have to constantly glaze the wall with glue. The seams and the sheath itself will lie flatly, snugly to the surface.

Perhaps all of the above advantages already make it irrelevant whether the walls should be primed before gluing the wallpaper. It is quite clear that it is necessary to do this to achieve a truly qualitative final result. Nevertheless, the list of benefits can be expanded if you take a deeper look at the essence of the matter.

Surface of surfaces

Suppose, it is planned to carry out usual cosmetic repair without special expenses: to delete only old and to paste new wallpaper. In this case, the home master is not particularly puzzled by any plaster-fillers and simply glues on the base that is available. Most often it is either concrete, or through a stump-deck a plastered wall. Well, let the final result remain on his conscience. In the end, it was supposed to be a budgetary version of repair on the principle of "clean - and okay." But in fact many today are thoroughly approaching the issue of preparing walls, spending a lot of money and energy for finishing work. And here it is worth noting two points, when the primer is not what you need, but simply vital. Because the rejection of this stage is fraught with very deplorable consequences.

If you are going to glue the wallpaper on the plastered walls or plasterboard, do not even try to negatively answer the question of whether you need to primed the walls before wallpapering. Preparation of this kind is necessary. Moreover, it is better to prime the surface twice. Why is this necessary? First of all, in order to strengthen the surface. If this is not done, then you can suffer twice - now and during the second repair. At present, the unprimed surface can swell from the glue and fall off just under the wallpaper, creating defects incompatible with the notion of "beautiful interior". After a time when you want to remove old wallpapers that have become old, you will tear them from the wall with the pieces of plasterboard and putty. What does this mean? The fact that there is a repetition of the walls.

We hope that we have convinced you of the necessity of priming the surface. Then we'll tell you how and what to do next.

Types of primers

It is worth noting that there are quite a lot of primer blends on the market, and they differ markedly in composition, purpose, and cost. But there are four types of them. These are glyptalic, alkyd, perchlorovinyl and acrylic. If you do not know what to wall primer before wall wallpapering, the material should be chosen based on the characteristics of the pasted surface.

Alkyd mixtures are ideal for wood, but not particularly friendly with plastered surfaces. So, if you have to glue on a fiberboard, chipboard or other surface of this kind, then get this kind of soil. The most popular and relatively budgetary compounds are primers of the Tikkurila brand.

Glyftalevaya suitable for wood and plaster. But she has one drawback - she dries a day. The most popular formulations are GF-021 and Ecol.

Perchlorvinyl soils, as a rule, do not apply to wallpaper, as they are used more for outdoor work.

Acrylics belong to the category of universal, quickly dry and are ideal for our purposes. The most common brands are "Ceresite", "Snowball" and "Pufas". So, if you do not know what to primed the wall for wallpaper, buy one of the acrylic mixtures - just do not lose.

Surface preparation

If you plan a budget repair, then you need to remove all the old wallpaper, clean the walls of dust, inspect them and carefully fill all available defects with putty. After this, you can start priming. In the same case, when large-scale finishing works are envisaged, the primer can be applied only after the finishing coat has been peeled off. That is, it will be the final stage just before the pasting.

Than primed

Ideally, it is best to use, of course, a spray gun or a miniature atomizer. But for lack of these you can use a roller or brush. The latter method is considered preferable, though labor-intensive. The application of the brush promotes deep penetration of the soil, while the roller more wet the floor than the wall.

How to primed walls: rules

Work should be in gloves and preferably a respirator. If you have a good floor covering, which you are not going to repair, then it should be carefully covered or immediately cleaned with a wet cloth rag. If this is not done, it will freeze, and after that it will be difficult to wash the surface. First, it is necessary to prime the top, then bottom. Work should be carefully, do not skip patches and carefully primed those places that absorb the composition very quickly. Apply the primer twice. The first layer should dry thoroughly.

How much time does it take? Usually such information is indicated by the manufacturer on the label. After drying the second layer, draw on the surface of the palm. Qualitatively the primed wall is smooth, the hand slides along it, like on ice. If you notice untreated areas, be sure to correct this defect.

Conclusion

Priming surfaces for wallpaper - this is an obligatory stage of preparation for pasting walls. The procedure will not only provide a long life to the decorative coating, but also protect the surface from the appearance of dampness and mold. So, if you want to get a really good result, do not be too lazy - pound the walls under the wallpaper.
