Karndean Designflooring and Underfloor Heating
Our planks/tiles are suitable over underfloor heating systems, but they should have been insulated so that its surface temperature does not go over 27°C (80°F).
The underfloor heating must be switched off 48 hours before, during, and 48 hours after the installation, then temperature gradually increased (typically 3°C/hr) to desired warmth.
Please consult the manufacturers to make sure their system is compatible with our flooring. Mesh/Wire systems must be bedded into a base coat of reinforced fibre smoothing compound to cover the wires or mesh. Then a second coat of primer and reinforced fibre smoothing compound should be applied as a finish coat. This is applicable for both concrete and timber construction subfloors.
Prime surface before applying a compatible smoothing compound to a minimum of 3mm.
