How the pasting is done?
The type of paint used to cover them determines the technique for pasting the wall. While each of them is unique, they are all not hard or time-consuming.
- Acrylic or water-based paint. The top layer of the surface is removed with a solution of solvent and primer in a 1:1 ratio. After which it is necessary to allow time for drying. Next, the primer is applied so that the wall becomes rough. This will ensure reliable adhesion of the wall and wallpaper. They begin to glue the canvases only after the building material has dried well.
- Oil paint. Before you start gluing the wallpaper, you need to remove the old layer of paint. This is done with a spatula. When the paint is removed, the wall must be thoroughly primed. After all the composition has dried, the wall surface is treated with sandpaper. Then another layer of primer.
Even the thickest wallpaper won’t be able to hide wall paint that has been painted in vivid, attention-grabbing hues. Thus, in this instance, removing the old coating entirely will be the only appropriate course of action.
It is advised to carry out a small experiment if you are unsure if the wall paint will hold up against the new finish. Using scotch tape, quickly tear off the sticky side after applying it to the wall. New wallpaper is adhered over the old one if the paint does not start to peel or crack.
How long does it dry?
The amount of time it takes for the surface to dry varies depending on the kind of wallpaper and the glue’s quality.
- vinyl sheets with a non-woven base dry from 24 to 48 hours;
- the rest dry within 18-24 hours.
Only moisture is released in the first one to two days. The adhesive composition doesn’t start to polymerize again until after this point.
