Wall priming for a firm and reliable covering

Just like floors, the appearance of walls can be improved using tiles or natural stone materials. As with a tiled floor covering, the wall needs to be carefully inspected and prepared before the elegant tiles are installed using a special tile adhesive. A key step in preparation is the application of a high-quality primer. The primer not only regulates the absorbency of the substrate but also serves as a bonding agent and a protective coating as well as improving the strength of the substrate.
