Installation

Concrete Subfloors

When installing any type of tile backer board onto concrete subfloor we recommend using Ultra™ flexible tile adhesive, please make sure the floor is primed with a suitable primer before installation.

Wood subfloors

When installing onto wooden floors we recommend using Ultra™ flexible tile adhesive in addition with ProWarm™ insulation fixing pack or suitable screws and washers at every 300mm centres. This is approx 15 fixings per board
