Screed composition and method of use
TLDR
In this paper, a method of using the screed composition is provided comprising mixing the cement, additives, EPS beads and water at or adjacent a point of use and applying the mixed screed mixture to a surface to be coated at said point-of-use.Abstract:
A screed composition comprising: cement; additives including at least a surfactant and a foaming agent; expanded polystyrene beads; and water. The additives may further comprise an accelerator. The screed composition may have a density of between 80 and 300 kg/m3. The EPS beads may have a size of between 1 and 8 mm and a density of between 8 and 16 kg/m3. A method of using the screed composition is provided comprising mixing the cement, additives, EPS beads and water at or adjacent a point of use and applying the mixed screed composition to a surface to be coated at said point of use. The method may comprise: adding the additives to at least a portion of the water in a mixing device; adding the EPS beads to the water and additives in the mixing device and mixing for a period; adding the cement to the mixing device and mixing for a further period. The surface to be coated may be a subfloor. At least the cement, water and EPS beads may be separate from one another prior to mixing at or adjacent the point of use.read more
