Ceramic floor tiles can be glued to the so-called. difficult substrates with the help of flexible adhesive mortars. In the case of old plank floors, it is worth using the Ditra mat. First, all the gaps in the floor must be sealed. Then spread a layer of adhesive mortar on the boards and press the mat into it. After the mortar has hardened, the adhesive mortar is normally applied on top of the mat and the ceramic tiles are glued.. The mat will compensate for any stresses arising in the sub-tile layer.
