Cement based screeds are very responsive to underfloor heating; due to the fact that they can be laid in very thin sections and have a high thermal conductivity of up to 2.9w/mk.
Since this product is a cement based screed; floor coverings can be applied much faster than calcium sulphate screeds which require a final moisture content of 0.5% which can delay floor finishing’s by months.
Whereas CES cement based screed can be tiled at a final moisture content of 5% and timber floors can be installed at a final moisture content of 2.8%; speeding up the entire build process.
Compared with other liquid screeds which generally need to be forced dried with underfloor heating; cement based screeds can be used in non-heated floors as it doesn’t require force drying to remove moisture.
We recommend you get your flooring contractor to carry out a moisture test before commencing any flooring.
Key Benefits
Thinner sections compared to traditional screeds. 25mm above underfloor heating pipes.
Larger floor area without joints (up to 150m2).
Exceptional Thermal Conductivity (up to 2.9W/m.k).
Reduced drying times: 5 days for tiling and 28 days for wooden floors in non-heated floors, in heated floors 14 days for tiling and 21 days for wooden floors. This is dependent on drying conditions or “after suitable moisture test.
Self-compacting – no voids around under floor heating pipes.
All floor coverings can be applied with no need for surface sanding.
More thermal insulation can be used in floors, compared to traditional sand cement screed which leads to a better u value for your building.
Minimal Drying Shrinkage (<0.05%).
Foot traffic after 24 hours.
Can be applied in wet areas.
Can be forced dried after 7 days.
Compatible with all cement based tile adhesive, no priming of surface required.
No Surface Laitance (Dust) after curing.
Easy Installation; up to 1000m2 per day (Reduces time & costs).
Lower Running costs for underfloor heating systems when using Cemfloor.
This is due to the exceptional thermal conductivity of up to 2.9W/mk and the ability to lay thinner screeds over the underfloor heating pipes.
Substrate
CES cement based screed is designed for use as a bonded thick levelling screed on concrete, as a floating screed over thermal or acoustic insulation, or as an unbonded screed on top of a plastic membrane.
Floor Covering
Is compatible with all floor coverings and cementitious adhesives and floor levellers.
Application
Should be used in accordance with BS 8204-7:2003 ‘Code of Practice for Pumpable Self-Smoothing Screeds’.
To ensure a high quality screed it is recommended that application is carried out by a specialist screeding contractor. The freshly poured screed will need to be levelled using a dappling bar, ensuring to dapple the surface in two passes at 90 degrees.
