Primer
Grout and leveling compounds if the water is removed from these products too quickly, the setting of the material can be impaired. Primers serve to protect and at the same time improve the conditions of detention.
In the case of non-absorbent and dense, smooth surfaces, it is not possible to connect the material to the surface. Here the primer acts as a bonding agent and ensures the necessary connection with the substrate.
Primer - necessary preparation for a flawless result
So that tiles can ensure a pleasant room climate for many years without losing their flawless appearance and good hold, the substrate must be prepared accordingly. A special deep primer or a tile primer, which increases the effectiveness of the tile adhesive, should therefore be applied to the substrate.
Tile primer and tile adhesive - perfect symbiosis for good adhesion
Basically, the tiles are always attached to the substrate with a special tile adhesive. Since most substrates naturally have less good adhesion properties, a pre-treatment with a special tile primer is necessary in most cases. Mosaic tiles in particular place high demands on the subsurface. The primer ensures that an evenly absorbent surface is created, which can form a symbiotic connection with the tile adhesive.
Perfect preparation leads to the goal
Plaster of paris and old concrete substrates must be primed with particular care. These materials are very absorbent and tend to remove too much moisture from the tile adhesive. This greatly reduces the liability. If the substrate is carefully primed before the tiles are laid, there are no undesirable side effects that could affect the end result.
