Why do I need a primer when wallpapering?

Today, not everyone knows about the benefits and purpose of wall primers, as long-term construction practice proves. Priming can seem like a waste of effort, time and money, if you look at the beautiful and even walls that are already prepared for wallpapering or painting. However, skipping this important stage in the future will lead to very sad consequences. The paint may peel off, the wallpaper may peel off. On the surface of the finish after some time ugly spots may appear. The primer is something that helps to combine the finishing materials and the walls as much as possible, so you must use it if you want to get a high-quality result.

The primer, after application to the wall, is absorbed into the material. She creates a very strong connection. Concrete dust, small fractions of brick, plaster or other foreign materials do not remain on the surface of the wall. The adhesive properties of the film that forms when the primer is applied are very high. Almost any finish after priming will be applied with high quality and durable. The mill cannot suck out moisture from the used mortars and adhesives, since the film reliably protects the applied material from this. Covering the walls with some types of primer should be done several times. All information is usually contained in the instructions or on the packaging of the material.

The fact that one coat of primer is not enough can be judged by the results of application. For this, you just need to run your hand over the wall surface, waiting for the material to dry out.

It is necessary to repeat priming if foreign particles from the wall remain on the hands. Most often, more than two or three times the primer before wallpapering is not required.

There are several types of primers on sale. When choosing, attention should be paid to the purpose of the material, the planned level of humidity during operation, as well as the type of surface to be coated. Only the base of the wall, for example, is covered with so-called primers, which also apply to primers. There are options that are laid between different layers of material to enhance contact. Recently, deep penetration primers have often been used. They are ideal if wallpaper needs to be pasted on friable and loose wall materials.

Applying a primer makes it possible to save expensive wallpaper glue. The consumption of materials is significantly reduced, since they are not absorbed into the wall due to the presence of a waterproof film.
