Description
In a shower, the water does not stay on the stone. It travels through the joints, reaches the wall, and the wall absorbs it.
This grey compound is spread on the wall before the stone is bonded and forms a continuous film that water will not cross. It is the step nobody sees once the job is done — and the only one you cannot put right without tearing it all out.
This 5 kg bag is small: it covers 1.7 m². It suits a splash zone, a strip behind a basin. For a shower, take the 20 kg bag.
