1. The flooring should be laid at a room temperature of at least 18°C, a floor temperature of at least 15°C and relative humidity between 50 and 75%. Do not ventilate while laying.
2. For the best appearance, lay KRONOTEX pointing away from the principal light source.
3. Before laying, calculate how wide the last row of panels will be – it may be necessary to cut in lengthwise, but it should not be less than 5 cm wide. This may make it necessary to cut the first row of panels as well before starting.
4. KRONOTEX flooring should be laid using the floating method. In other words, the panels may not be glued, nailed or otherwise fastened to the subfloor. Affix wall base only to the walls, not to the floor!
5. Please following the laying instructions precisely.
If the flooring is improperly laid, the warranty is voided.
If any problems arise, halt the laying work immediately and consult with your dealer.
1. KRONOTEX flooring can of course also be glued over the entire surface. Beforehand, however, it is necessary to determine the nature of the subfloor and how it should be pre-treated to level it (e.g. by painting, filling with levelling compound or grinding). Acc. to DIN 18202 table 3, it is necessary to level out variations in flatness that exceed 2 mm per 1 m.
2. Make sure that the subfloor is absolutely dry, level, solid and clean. Pre-existing expansion joints should be kept in the same places and provide the same amount of space for the floor to move. When using this laying method, please use a polyurethane (PU) adhesive.
Please consult a professional!
DO NOT glue down KRONOTEX flooring over radiant floor heating..
When laying KRONOTEX flooring, make sure that the subfloor is suitable.
Suitable are, for example:
• Old flooring such as PVC (provided it is fully glued and not floating), wood floors, ceramic (dry), linoleum
• Cement screed (max. residual moisture of 2.0 CM%)
• Dry and floating anhydrite screed (max. residual moisture of 0.3 CM%)
• Magnesite screed (max. residual moisture of 3.0 CM%) –
Have a floor installer measure the residual moisture..
High Humidity spaces ((bathrooms, laundry rooms, saunas etc.), carpeting and woodstone are not suitable
The subfloor must be absolutely dry, level, solid and clean. Small variations in flatness can be evened out by an underlayment (to attenuate footfall sound); spots higher than 3 mm per metre need to be ground down, and low spots must be filled in with a levelling compound.
It is no problem to lay KRONOTEX flooring over hydronic radiant floor heating as long as you follow the special instructions. The properties of our laminates – such as favourable thermal conductivity, natural underfoot warmth and uniform distribution of the surface temperature – actually help to reduce heating costs.
The preparations for laying laminate flooring over floor heating include:
1. Make sure to warm mineral subfloors before laying to prevent unacceptable amounts of moisture from being released.
2. Have a heating installer assess the effects of heating.
3. It is very important to allow for warm-up and cool-down phases. When laying, the surface temperature of the floor should be at least 15°C.
4. In order to keep moisture and water vapour out, lay a PE membrane underneath (0.2 mm thick).
5. To attenuate footfall noise and provide thermal insulation, underlay with PE foam or another suitable material. Suitable as acoustic insulation is foamed PE, a KRONOTEX underlayment mat or KRONOTEX laminate flooring with Sound Design acoustic underlayment.
6. When starting to heat each winter, gradually increase the floor heating by 5°C each day until it reaches the optimal flow temperature. The temperature of the floor surface should not exceed 26°C.
