About liquid screed
Liquid screed is a superior self levelling compound which offers a number of benefits over the traditional screed mix. It is made from anhydrite binder instead of cement and can reach strengths upwards of 30 Newton.
This sort of compound is best used with underfloor heating systems as it is easily heated and will retain the heat for a longer period of time compared to the traditional sand and cement. Liquid screed can be used in both new builds and extensions
benefits of this product
Screed can be laid at a minimum depth of 40mm (50mm with underfloor heating pipes) allowing for more insulation and less material
Requires less man power to fit and is usually dry enough to walk on in under 48 hours.
Usually fitted at a shallower depths than sand and cement, allowing the floor to be more easily heated, therefor reducing energy bills. (liquid screed has about twice the thermal conductivity as traditional screed)
very low cracking and shrinking compared to sand and cement and it will not curl.
Can be forced dried by slowly turning on the underfloor heating system.
A guide to preperation
Make sure that the surface floor is brushed and level before laying down the sheets of insulation.
Lay the sheets of insulation flat on the subfloor and ensure that these sheets dont rock back and forward.
Next, lay down a thick polythene (500 guage) ensuring that all joints are taped and it is free from creases and punctures. Expansion strips should be applied to the perimiter walls.
Once these steps are complete, the underfloor heating system will be ready to install. Make sure that all pipes are securly clipped as they may float if not secured. Pipes should be filled before the application of the liquid screed.
Once all these steps are complete, it is best to give the area a final check to ensure that there is no holes where the liquid screed could run away.
