For pasting wallpaper walls need the following tools: wallpaper knife makhovaya brush, roller for applying adhesive to the wall and the wallpaper, wallpaper seam roller, a plastic spatula to smooth the wallpaper, scissors, tape measure. These tools needed for all types of wallpaper, but liquid. Before hanging wallpaper should prepare the surface of the walls. This requires a knife, with which all irregularities are removed from the walls. If before the walls were lime whitewash, it will have to pre-rinse with water.
Not so long ago, even 10-15 years ago, before pasting wallpaper wall does not apply a prime coating, but merely papered with newspapers. It was believed that the newspaper layer prevents the appearance of Fatty or glue stains on the wallpaper. At present, these issues are addressed through the use of any of the primers. A few words about the use of glue. They may be liquid, gelatinous, available in powder form and pellets, rods and films. In liquid adhesives adhesive is present as a dispersion (an aqueous solution with uniformly distributed therein particles of adhesive). Adhesive to dry powder adhesives, granules, rods and films in the solid state. To prepare the necessary glue viscosity, should be diluted with water (special thinners) or organic solvents.
Mediums use for the preparation of dispersions and solvents – for solutions. The viscosity of the adhesive (that is, according to her chosen method of application) is in direct proportion to the mass fraction of solids, which, in turn, shows how much glue is used to form the adhesive joint. The higher proportion of solids, the less glue will be spent on the job. It is essential that when the viscosity of the adhesive does not changed because it affects the uniformity of deposition on the pasted surface. The duration of the evaporation of solvents affect the duration of open time after application of glue, as well as a change viscosity adhesive composition prepared in the process.
