In the process of carrying out repair activitiesthe surface of most partitions needs to be pretreated. The modern building market offers a wide variety of canvases and periodically improves the technology of their gluing. Preparing the walls for wallpapering plays an important role at the time of the total volume of finishing activities. 
Scheme of putty stitches. The best outer layer for pasting partitions is a previously ground with plaster base with deep treatment with a primer. As a result, the coating turns out to be perfectly smooth, and the used compositions make the plane most suitable for spreading the glue. Speaking about the overhaul, you can start removing old canvases, eliminate stubborn stains, stains, cracks, chips, paint. All the above-mentioned deficiencies in the grounds before carrying out the work should be eliminated.
Proper surface cleaning
Wall cleaning scheme: a - cleaning with a scraper, b - smoothing with a cleft or a hinged grater, c - a drawing of the working tool. Preparing walls for wallpapering involves first of all getting rid of the old coating. It can be whitewashing, painting, old canvases. And it is not easy to perform such procedures. Neglect of this kind of work will lead to the fact that the pasted wallpaper can not keep on such a plane and quickly peel off. Plastered layer requires an assessment of the state of its appearance. To do this, check the base for cracks and crumbling areas. For this purpose, you can use a small hammer. A large number of shaky places gives cause for complete removal of the entire layer. Having completed the dismantling, you can carry out further activities. The preparation of walls for gluing canvases is often carried out in the process of major repairs in a room or apartment in a new house.
Wallpaper gluing scheme. Paint on a water-based basis requires a preliminary rinse, the oil is scraped off with a spatula in the areas of its peeling. If such a coating is difficult to remove, for this you can take a special composition or treat the partition with a primer of a transitional effect. On such a plane, the wallpaper is glued well. Presence of lacquer surfaces gives an occasion for processing with their emery cloth, after that the base is treated with putty or dispersion paint, which will ensure better adhesion of the adhesive to the plane.
To do this, the coating is wetted with warm water,waiting for some time, after which the canvas well depart from the partitions. Easier to get rid of paper wallpapers is easier. More dense matter is removed with steam or water, diluted with detergent. To facilitate the work, you can connect a spatula.
Mold sprouts are eliminated by specialmixtures or a deep action primer. Rust is removed by coating the substrate with special compounds, after which shpatlevanie is carried out. Divorces from water are removed by any insulating agent or primer. Back to contents</a>
Highlights of the preparatory activities
Scheme of priming the wall. Such measures will allow plastering of the surface, improve adhesion to the concrete base. In another version, the plaster can simply fall apart. Primer is applied to the plane using a paint roller, corner areas are smeared with a brush. The treated baffle must completely dry out. After this, it is plastered, until the outer layer is dusted.
As often happens, concrete partitions have some degree of curvature. For this reason, they are particularly in need of plastering the substrate.
This procedure is resorted to whenThe outer layer is fairly smooth, but there are minor defects. Spatting of the surface is preceded by the treatment of partitions with a deep action primer.
As soon as the ground is applied,you can start to paste the canvas. A dilute adhesive or acrylic primer allows you to do this best. Once the walls are prepared, you can start working. The optimum room temperature will be 18-20 ° C, there should be no drafts. Switches and sockets need to be removed, after completion of the events they are put in place, creating a neat and fresh look.
