If our matting or cable system has been covered with a layer of flexible levelling compound prior to tiling, observe the drying time recommended by the manufacturers before tiling over.
A thin layer of levelling compound will provide protection for the heating mat or cable from mechanical damage. However, this step is not compulsory and you may decide to install the tiles in a single operation directly on top of the mat or cable.
It is OK to walk in stocking feet and kneel on the heating mat or cable, but avoid contact with sharp objects.
DO NOT drop tiles onto the heating surface as this could damage the heating element.
