Weberfloor 4360 base flow rapid is a pumpable, self-drying, levelling screed, having a rougher surface structure than ordinary levelling compounds. Before floor covering, the surface must be primed and covered with a low alkali fine smoothing compound or a levelling compound. The material is supplied as a dry powder consisting of high alumina cement, natural sand, complementary binder and additives. The product is free from slag and casein. Weberfloor 4360 base flow rapid is recommended for applications where there is a need for thick layers of 20 – 80 mm and simultaneously reducing the drying time.
