Before installing our mats or cable you should prepare the subfloor. Clean the floor and prime with a coat of PVA, a water based adhesive primer. This will also help the tile adhesive and/or levelling compound to bond with the subfloor.
Any good tile or hardware outlet will supply PVA primer.
Our mats have a self adhesive backing which is extremely sticky for simple fixing to the sub-floor. The adhesive extends to the cable loops that run along each side of the mat.
Flexible tile adhesive and fillers are required e.g. latex, acrylic or polymer based. These will compensate for any tile movement and possible cracking caused through expansion and contraction. A flexible grout should also be used.
