Firmax is an ultra-thin cement and silica based substrate suitable for a range of floor finishes which is specifically designed to work with underfloor heating.
The system comprises of 2 x 6mm boards each of which are supplied with one side prepared with an adhesive. Installation is simple. The first layer of Firmax boards is laid according to the supplied instructions. Boards can be cut with a Stanley knife and snapped to size. Before installing the second layer the protective film covering the adhesive of both layers is removed and the panels pushed together.
The system works successfully as when installed correctly all joints are overlapped.
