Will I need any other materials to install ThermMAT or ThermCABLE ?
Before installing ThermMAT or ThermCABLE you should prepare the subfloor. Clean the floor and prime with a coat of inexpensive 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 and it will cost less than 5 for one litre. ThermMAT has a self adhesive side which is extremely sticky to allow easy 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 movement of the tiles and possible cracking caused through expansion and contraction. A flexible grout should also be used.
