webercem spray DS
webercem spray DS is a pre-bagged, readyto-use, polymer-modified, cement based structural concrete. It contains graded inert limestone aggregates designed to suppress dust. The formulation has been designed specially for dry process spray application to give high strength, low rebound and wastage, and to maximise the application thickness. Conformity testing to BS EN 1504-3 has confirmed that webercem spray DS meets the requirements for a Class R4 repair product.
