Problems of spraying real stone paint on exterior wall tiles

There are two reasons why real stone paint can't be directly sprayed on exterior wall tiles.

Uneven surface of ceramic tile

First of all, the tiles have joints, which are not flat in themselves. Spraying real stone paint will affect the visual effect because the base is uneven.

Real stone paint and ceramic tile are not firmly bonded.

Secondly, the surface of ceramic tile is smooth, and the bond between real stone paint and ceramic tile is not firm, which will definitely lead to the hidden danger of falling off in the future.

Spray interface agent, batch of external wall putty

Ceramic tile walls can be sprayed with interface agent first, then with putty on the outer wall, and then with real stone paint, so that the real stone paint will not fall off and the visual effect will not be affected because of unevenness.
