Subfloor preparation and adhesives

Subfloor preparation and adhesives

Underfloor Heating

Ensure that the Underfloor Heating System is fully commissioned, tested and brought up to maximum design operating temperature before applying Surface DPMs and Underlayments. The surface temperature of the concrete/sand cement screed must not exceed 27C when fully commissioned, as per the British Standards codes of practice and the Floorcovering industry maximum agreed level.

The underfloor heating system should be switched off at least 48 hours before, during and after the installation of the floor coverings, adhesives, Surface DPMs and underlayments and gradually recommissioned in accordance with the manufacturer’ recommendations.

Screed/concrete surface temperatures should be checked using a Raytek (or similar) hand held monitor. Note! Higher surface temperatures will accelerate the curing of smoothing compounds, adhesives and surface DPMs and may reduce overcoating and installation windows (Please refer to Tremco product literature and contact your Tremco Technical Representative for assistance).

During the period of decommissioning an alternative heating source should be provided, if required, to ensure that the area of installation is kept at a constant temperature of between 18C 27C.

Failure to follow these guidelines can result in the floorcovering de-bonding, shrinkage, joints opening,

and on some occasions discolouring.
