tile adhesive in powder form
A special form of powder tile adhesive is the so-called flexible adhesive. This is usually more expensive than cement mortar, but contains plastic additives (polymer additives) which, among other things, ensure that it hardens relatively flexibly.
It can therefore better absorb vibrations, tensions and other movements of the substrate. This reduces the risk of individual tiles chipping or cracking. These additives also increase the adhesive strength of the flexible adhesive.
