When installing Kronotex flooring, please make sure there are suitable sub-floors. They include:

1. Old flooring, such as PVC (if full-surface adhesive is used), wooden floors, ceramic tiles (dry), linoleum

2. Cement screed (max. residual moisture 2.0 CM %)

3. Anhydride screeds (max. residual moisture 0.3 %)

4. Magnesium-screeds (max. residual moisture 3.0 %)

The following are not suitable: damp rooms, carpets and a composition screed made of wood shavings and magnesium oxides or chlorides.


The sub-floors must be absolutely dry, level, firm, and clean. Minor unevenness can be compensated for by using underlay material (sound insulation). Unevenness of more than 3 mm in a one metre area should be sanded down or smoothed over with a filler.

The installation of Kronotex flooring on warm water underfloor heating poses no problem, as long as our special instructions are followed. The insulating properties of our laminates, their natural underfoot warmth and the equal distribution of surface temperature help to save on heating costs.


Preparations for fitting on underfloor heating should include the following:

1. Mineral screeds must be heated prior to installation to prevent the escape of unwanted moisture.

2. It is particularly important to adhere to the heating and cooling phases. The surface temperature of the floor should be a minimum of 15° C.

3. To create a humidity and vapour barrier, a PE foil (0.2 mm) must be placed underneath.

4. For impact and thermal insulation, underlays such as PE foam or Kronotex Laminate flooring with ”Sound Design” footfall sound reduction may be used. Or simply use our "Kronotex Kombi" underlay mat.

5. At the beginning of each new heating period, increase the underfloor heating by 5° C per day until the maximum desired temperature has been reached.

6. The surface temperature of the laminate flooring should not exceed 26° C.
