Installation

Please Note: The following is intended as a guide only. Always refer to the full installation manual for instructions.

Ensure that the subfloor is solid and suitable for tiling, free from dust and debris. Wooden subfloors should ideally be reinforced to prevent flexing and the possibility of tiles dislodging.This can be reinforced using a suitable WBP or Marine plywood or insulated tile-backer boards such as ProWarm™ Backer Boards. Bitumen bases should be covered with a suitable backerboard or a 3-5mm levelling compound.
Prime the floor using the acrylic based primer (see advice for anhydrite screeds).Once primed leave to dry (typically 1-2 hours). Once primed avoid any excess foot traffic over this area. The purpose of priming is to promote greater adhesion of the tile adhesive by reducing the amount of moisture absorbed into the subfloor.ALWAYS CHECK with tile adhesive/levelling compound manufacturer that the primer is suitable for use with their product/s, please contact our technical help centre if you are in any doubt.
If using ProWarm™ insulation tile Backer Boards or XPS insulation boards, do so in accordance with the manufacturer's instructions, we do advise staggering the boards in a brick bond style and making sure the boards are fixed using suitable flexible adhesives to solid floors and/or mechanically fixed to wooden subfloors @ 300mm centres using suitable screws and washers.
