How many years have passed since the repair in Soviet times consisted of applying fresh whitewash on the ceiling and gluing wallpaper with the help of hand-welded flour paste on the old layer of wallpaper! By and large, it was this old layer of wallpaper that was not peeled from the walls that served as a kind of primer. The modern world has changed. The construction market of finishing materials offers a variety of types of finishing materials, among which the primer of the walls under the wallpaper is not the least.
Why is a wall primer necessary for wallpaper?
It doesn’t matter where you live, in a new, well-equipped high-rise building or an old apartment - “Khrushchev”, as a rule, there are no even walls. Even perfect walls can be covered with an old coat of paint or whitewash, which simply needs to be removed before the walls are primed.
The primer for walls under the wallpaper is a process that should not be neglected, because the quality of the wallpaper “grasps” with the surface of the walls depends on the correctly applied primer. Walls made of various materials have different suction capacities, therefore, if you do not use material such as wall primers for wallpaper, the glue (wallpaper) is uneven, which ultimately leads to the formation of “bubbles” and peeling corners. The primer of the walls under the wallpaper allows the latter to gain a foothold, while remaining elastic for some time, which makes it possible to adjust the canvas.
The primer of the walls under the wallpaper can be carried out with a universal material suitable for almost any basis, for any building material. Hence its name "Universal". It is used both for interior decoration and outdoor work, dust-free surface.
The primer allows you to increase the strength and fastening with the applied materials, it allows you to save on materials such as wallpaper glue and paint, reducing their consumption. The primer for walls under the wallpaper is an environmentally friendly finishing material that allows the walls to "breathe" without clogging the pores.
Therefore, it is better to invest and spend time than spoil the new wallpaper and your mood.
What is required:
- wallpaper primer
- capacity (bucket)
- brush (roller)
It does not hurt to purchase a plastic net and, if possible, a telescopic rod. The primer of the walls before wallpapering suggests its choice. It is sold both in dry form and in diluted form, completely ready for use. Any primer for walls under the wallpaper is offered with instructions for its use, after reading which you can find out how much material is needed per square meter of surface. As a rule, the average consumption of the Universal primer is about one hundred and fifty milliliters per square meter of area.
The primer of the walls under the wallpaper will need a two-layer, if your walls were previously poorly plastered. Following the instructions, we dilute the dry primer with water, after which we insert a mesh into the container that will not allow the brush or roller to soak heavily. Otherwise, the primer will drain from them. The telescopic bar is very convenient to use on a par with the roller, it will help to avoid dragging the ladder and will penetrate into all remote corners. We carefully treat the required surface with a primer using a brush at the joints and corners. After complete drying, you can assess the quality of the work done. Repeat if necessary.
After complete drying, you can proceed to wallpapering. Only after you apply the primer while making repairs in your home, you will be convinced that the primer of the walls under the wallpaper is a really necessary thing. High-quality repair for you for many years!
