webercem spray DSF - Concrete Repair

webercem spray DSF is a ready-to-use, polymer-modified, cement-based concrete mix. It contains inert limestone aggregates and dust suppressants. The formulation has been designed specially for dry process spray application to give high early strength, reduced rebound and maximise application thickness.

webercem spray DSF contains alkali resistant glass fibres. It has been designed to give higher tensile strength, reduced rebound and to minimise application thickness. The fibres help to reduce shrinkage cracking. Conformity testing to BS EN 1504-3 has confirmed that webercem spray DSF meets the requirement of a Class R4 repair product.
