Product Installation

The thin-layer mortar must be applied with a suitable spatula (a 4x4mm notched trowel is recommended). The choice of adhesive depends on the respective underlying: you can choose between a flexible hydraulic mortar or a quick setting mortar (Tile Adhesive)(DIN EN 12004/C2). The technical data sheets of the adhesive manufacturer must be observed. The isolation mats are pressed evenly using a suitable tool, the fleeced surface facing the adhesive layer. Where waterproofing is required, the joining points of the mats are covered with the sealing strip.

The tile laying (thin layer mortar method) can be started immediately after laying the sealing mat. If it is necessary to start immediately with the laying of the tiles, it is advisable to spread the adhesive in the cavities of the mat and comb the mortar (tile adhesive) thinly in a single step.

A full bonding of the tiles must be ensured. Minimum tile size: 50 x 50 mm. Lower thickness tiles don´t provide adequate durability in these settings because there is a high risk of breakage.
