How to install

1. Make sure the sub-floor is free of any loose material that could impair adhesion. It must be
level and able to bear weight. Any levelling must be completed before its
installed. The adhesive should be chosen dependent on the nature of the sub floor. The
adhesive must be capable of bonding to the sub floor surface and to the backing fleece of
the mat

2. For most surfaces use a water-based thin bed adhesive (C2 quality). The adhesive is applied
to the sub floor using a serrated trowel (6 x 6 mm) and the matting bedded into it.

3. As soon as the matting has been installed and the adhesive has cured, the
electrical heating system can be installed at 75mm Spacing.

4. Loose wire Area Covered m2
300 watt 1.5 to 2.0m2      200 to 150 Watt per m2
450 Watt 2.25 to 3.0m2    200 to 150 Watt
600 Watt 3.0 to 4.0m2      200 to 150 Watt
750 Watt 3.75 to 5.0m2    200 to 150 Watt
1050 Watt 5.25 to 7.0m2  200 to 150 Watt
1500 Watt 7.5 to 10m2     200 to 150 Watt

5. Tiles can then be installed using a thin bed adhesive appropriate to the flooring.

Practically, it is advisable to apply adhesive in one operation, embedding the heating cables in that
process. Install the tiles after pre “buttering” the underside. The tiles must be embedded in
the adhesive to achieve solid bedding. The depth of the serrations on the trowel must be
appropriate to the tile format. Make sure this is all done while the adhesive is still fresh and
within its “open time”.
