CES Floor Screed Range

Description

There are 3 different products available in this range:

• C16/F3 - for domestic non underfloor heating
• C20/F4 - for domestic and underfloor heating
• C25/F5 - for commercial use

Tile on after only 4 days (if no underfloor heating) using a green screed adhesive!

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.

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.
