Warmup Ultralight

INSTALLATION

The subfloor must be clean and dry and if necessary, smoothed
with a self-levelling compound to give an even surface.
NOTE: The maximum permissible departure from a 2 m straight
edge, resting under its own weight on the subfloor is 3 mm. (SR1
Standard – BS 8204).

Prime subfloors with a dilute (1:4) SBR solution. For proprietary
subfloors refer to the manufacturer instructions.

Provided the subfloor is adequately prepared and clean, it may not be necessary to prime. This can vary depending tile adhesive selection. Please refer to the tile adhesive manufacturers instructions for priming information.

Ultralight should be installed using a flexible, cement-based adhesive. The adhesive should be trowelled out and combed through using a 6 mm x 6 mm (¼” x ¼”) square notch trowel to give a ribbed bed, any slight depressions in the subfloor being filled by the mortar.

NOTE: If you plan to apply a levelling compound over Ultralight
apply Warmup perimeter strip to the edge of the room to allow for
differential movement between the finished floor level and walls.

Ultralight should be laid on the freshly applied ribbed bed and
thoroughly bedded in to ensure that no voids are left beneath the
boards and they are solidly supported. All boards should be laid
with staggered joints.

NOTE: Allow the adhesive attaching the boards to the subfloor
to cure before laying electric underfloor heating directly onto the boards.
