In the process of carrying out repair activitiesthe surface of most partitions requires preliminary treatment. The modern construction market offers a wide variety of canvases and periodically improves their gluing technologies. Preparing walls for gluing wallpaper plays an important role at the time of the overall finishing work.
Scheme of filling seams.The best outer layer for pasting partitions will be a pre-sanded plaster base with deep treatment with a primer composition. As a result, the coating is perfectly smooth, and the compositions used will make the surface most suitable for spreading glue. Speaking about carrying out major repairs, you can begin to remove old canvases, eliminate stubborn stains, smudges, cracks, chips, paint. All of the listed defects of the base should be eliminated before carrying out work.
Proper surface cleaning
Wall cleaning scheme:a – scraping, b – smoothing with a flat or articulated float, c – diagram of the movement of the working tool. Preparing walls for wallpapering involves, first of all, getting rid of the old covering. This can be whitewashing, painting, old canvases. Moreover, it is not easy to perform such procedures. Neglecting this type of work will lead to the fact that the pasted wallpaper will not be able to stick to such a surface and will quickly peel off. The plastered layer requires an assessment of the condition of its exterior. To do this, you should check the base for cracks and crumbling areas. For such purposes, you can use a small hammer. A large number of shaky places gives reason to completely remove the entire layer. After completing the dismantling, you can carry out further activities. Preparing walls for pasting canvases is often carried out during major repairs in a room or apartment in a new house.
Wallpaper pasting diagram.Water-based paint requires preliminary rinsing, oil-based paint is scraped off with a spatula in places where it peels off. If such a coating is difficult to remove, you can take a special composition or treat the partition with a transition primer. Wallpaper sticks well to such a surface. The presence of varnished surfaces gives reason to treat them with sandpaper, after which the base is treated with putty or dispersion paint, which will ensure better adhesion of the adhesive to the surface.
To do this, the coating is moistened with warm water,wait for some time, after which the canvases come off the partitions well. It is easiest to get rid of paper wallpaper. Thicker materials are removed with steam or water diluted with detergent. To make the work easier, you can connect a spatula.
Mold stains are eliminated with specialmixtures or deep-action primer. Rust is removed by covering the base with special compounds, after which puttying is performed. Water stains are removed with any insulating agent or primer. Return to contents</a>
Highlights of the preparatory activities
Wall priming scheme.Such measures will allow plastering the surface, improve adhesion to the concrete base. Otherwise, the plaster may simply crumble. The primer is applied to the surface using a paint roller, corner areas are coated with a brush. The treated partition must dry completely. After this, it is plastered until the outer layer is dusty.
As often happens, concrete partitions have some degree of curvature. For this reason, they especially need plastering of the base.
This procedure is resorted to in the event thatThe outer layer is quite smooth, but there are minor defects. The surface puttying is preceded by treating the partitions with a deep-acting primer.
Once the primer has been applied to the base,you can start gluing the canvases. Diluted glue or acrylic primer allows you to do this best. As soon as the walls are prepared, you can start working. The optimal room temperature will be 18-20 ° C, there should be no drafts. Switches and sockets should be removed, after the completion of the events they are put back in place, creating a neat and fresh look.
