Pro Roc TH


Product for repairing deteriorated materials. PELICOAT PRO ROC ref TH is a mixture of ethyl silicate used as a binder to stabilize the microstructure of very deteriorated stones. It consolidates porous and absorbent mineral materials such as bricks, concrete, limestone, lime mortar…

The point of that mixture is the hydrophilic properties of the solvent used which makes it possible to spread mortar over treated parts after a shorter time than with PRO ROC and PRO ROC+
