Preparing the surface for wallpapering - cleaning the walls
Preparing the surface for wallpapering with wallpaper begins with cleaning of old or other finishing materials that adorn the wall before that( varnish, paint, whitewash and others).
- When removing old wallpaper use a spatula or trowel, with which you podedvayut over the edge of the canvas, and smoothly move the removable removable paper trim.
- The paints are removed manually - also with a spatula by scraping them off the wall surface or by using a drill and a special nozzle in the form of a metal brush. It is important to remember that when scraping paint, you need to use personal protective equipment - a respirator and goggles.
- If you need to remove the old whitewash, it is washed off with water: manually, using a maclavice - a special brush for whitewashing, or machine - using equipment that can create the right head.
Antibacterial treatment and wall leveling before wallpapering
The next step in preparing walls for wallpapering is the assessment of the surface condition. For this, the wall is carefully examined for the presence of fungus or mold. If they are found, then antibacterial treatment of the walls before the wallpapering with special composition or boric alcohol solution is made, after which the walls are allowed to dry and proceed to remove irregularities. To determine the unevenness, use a lace( long string, chalky), a long conventional or laser level. The laser level will immediately indicate all the irregularities, but in its absence, you can use the grandfather's method - two people stand at the edges of the walls, pull the string and lead it from the top down. Chalk leaves marks on a flat surface, the depressions remain clean, and around the protuberances are formed not traced areas.
If bulges are detected, they are removed with a hammer or a chisel with a hammer. Cracks in the wall are usually visible visually, hidden - reveal by tapping, after which the edges are cut to a solid surface. Depressions and cracks should be filled with putty or plaster before obtaining a perfectly flat surface. And even if a new wall is being prepared, which is pasted for the first time, it must also be leveled, since there is no ideal erection in nature.
Preparing the walls before painting the wallpaper for an ideal evenness is an extremely important step, since it depends on how the finish will lay down in the future. If you do not perform all the steps with sufficient responsibility, then when you pasting, you can have serious difficulties - there will be gaps between the panels or vice versa - striking overlaps.
Wall priming before wallpapering
After leveling the priming of the walls before wallpapering, use a wide brush or roller and a special composition - the primer. Also, this work can be done with a spray gun, but with the use of machinery, the cost of the used soil will be 20% more.
You can glue the wallpaper and on the plaster, but the primer is made to finally level the wall and increase the bonding properties between the surfaces to be joined. Also, a good primer prevents the development of putrefactive bacteria and fungi.
After priming, the walls are allowed to dry and only then proceed directly to the gluing of the wallpaper. However, those who have made all the preparatory stages correctly, will enjoy themselves at the final stage of the repair.
