Wykamol Dryseal Masonry Protection Cream 3 litre

DRYSEALstands out. As opposed to conventional liquid products,DRYSEALcan be applied in just one working operation to achieve the desired loadings for maximum effectiveness. Dependent on porosity, the effective siloxane ingredient penetrates the substrate within a short time (30 minutes to several hours) where it reacts to become a polymer silicone resin.DRYSEALremain permeable to water vapour (allow the structure to ‘breathe’).DRYSEALhas been formulated to penetrate as deeply as possible into porous masonry substrates and this provides optimal protection against the absorption of water and pollutants as well as frost/salt damage. This effect should not be confused with the beading effect often associated with water repellents. The beading effect demonstrates the surface action of a water repellent but may not be significant when assessing a product’s overall performance (resistance to rain water penetration under wind pressure).
