How to prepare the wall?
The wall mural is attached to a clean, dry and slightly absorptive wall.
A fresh wall – covered with plaster finishing coat, drywall or other absorptive building materials – has to be grounded with a special grounding medium (or watered-down wallpaper paste (at least 2 hours before installation).
Pre-painted walls are to be washed with wall cleaner, and in the case of thick layers of silicone and washable paint – sanded down and degreased. If another wallpaper was placed on the wall, it has to be entirely removed and any visible damage has to be repaired, whereupon the entire surface is to be grounded.
