With its unique thixotropic consistency and excellent water-repellent properties on a range of building materials, DRYSEAL stands out. As opposed to conventional liquid products, DRYSEAL can 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.
The initial white layer disappears completely and, since the effective ingredient is the same as in conventional liquid water repellents, substrates treated with DRYSEAL remain permeable to water vapour (allow the structure to ‘breathe’).
DRYSEAL has 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).
