Proper pretreatment of the substrate is a prerequisite for the success of any upholstery. However, good surface preparation means not only removing old wall coverings and for the repair of damaged areas, but also the cleaning and Priming the subsurface. If you wonder why your wallpaper does not hold, exhibit discoloration or have wrinkles and open collisions, you should look at the underground closer.

Why the surface should be top …

If wallpaper drying on the wall, of the voltages that need to be collected from the ground.In the area of ​​the seams these stresses are particularly large. then If the ground is not sufficiently prepared, the wallpaper will dry not uniform. And also incorrect preparation of the substrate can cause problems and poor Decorating image. So do not let prefer the ground a little more time. It is worth it .. Most of the work must not be repeated with any decorating process.

The base coat is intended to ensure adhesion of the subsequent wallpapering. According to Internetages, a retro wallpaper require a uniformly absorbent base surface.

The undercoat should strengthen slightly loose plasters and chalking paintwork. In plasterboard the paint to prevent softening of the surface, so wallpaper can be separated from the card later.

Basecoats should shut off the ground in any case. Have you applied too much primer, you must open the surface by sanding again.

A primer is in principle necessary to strongly absorbent plaster, plasterboard and plasterboard. Surfaces that have been papered multiple, no longer need to be primed usually. For priming wallpaper substrates, always use for reasons of environmental protection and occupational safety, a water-based primer.

The primer can also bind residues of glue, Kalkfarben- and mixing binder coatings that are to be removed actually before wallpapering.

Priming is usually only with new plaster and new plasterboard and plasters which sanden necessary. It should not be primed before each wallpapering.
