Cement-based, self-levelling liquid floor screed which complies with EN 13813. For domestic flooring and underfloor heating.Features and benefits:Thinner sections compared to traditional screeds.Larger floor areas without joints.Exceptional thermal conductivity.Reduced drying times compared to other screeds. Moisture-sensitive floor coverings can be applied when the screed has dried to a moisture content of <2.5%CM.Self-compacting – no voids around underfloor heating pipes.Can be applied in wet areas.Can be forced-dried after seven days.Lower running costs for underfloor heating systems.No surface laitance (dust) after curing.Compatible with all cement based floor adhesives.No need to use surface primers or sealers before applying adhesives to the screed.Applications:Cemfloor screed is designed for use as a bonded levelling screed on concrete, as a floating screed over thermal or acoustic insulation, or as an unbonded screed on top of a plastic membrane. It is compatible with all types of floor coverings and cementitious adhesives, including fast-track systems, damp-proof membranes and floor levellers.Technical characteristics:Compressive strength: >20 N/mm².Flexural strength: >4 N/mm².Density: Wet = 2200 kg/m³; Dry = 2000 kg/m³.Shrinkage (28 days): <0.05%.Fire rating: Non-combustible.Floor flatness: SR2 (minimum).Open to light foot traffic: After 24 hours.BRE impact test (2 kg) <2 mm.Screed thickness (minimum):Bonded: 25 mm.Unbonded: 30 mm.Floating over insulation: Residential: 35 mm; Commercial: 40 mm.Cover to heating pipes: 25 mm.
