As a rule, the initial color of wallpaper intended for painting is white. Depending on the material of manufacture, distinguish:

• Paper.
• Vinyl.
• Cullets.
• Non-woven.

Each of these types of wallpaper materials has its advantages and disadvantages. For example, cullet is made of hypoallergenic material. They, in addition, have well-defined antistatic properties. In their manufacture uses natural raw materials, so they are environmentally friendly. The downside of cullet is a relatively large mass of finishing cloth. For good adhesion, a special primer and special glue are used.

Important! When gluing walls with glass wallpaper, glue should not be applied to the canvas (only on the surface to be glued). When working, you must observe safety measures. Work must be carried out with gloves and long-sleeved clothing. This rule should not be neglected, since the small glass threads that form the wallpaper, getting on the skin, cause irritation.
