SilKön™Sealer is a penetrating, solvent based sealer designed for use on concrete, concrete pavers, natural stone and other porous cement based surfaces. SilKön™Sealer will enhance the color (natural or integral color) of the substrate without adding the gloss and plastic look associated with traditional film forming sealers. SilKön™ is an excellent way to improve protection without diminshing natural texture. Once treated, the surface will have extra protection against the elements and staining. Coverage: 150-200 sq ft per gal, surface dependent. Only (1) coat/treatment recommended or required. Application: 3/8" nap roller. This surface must be porous for SilKön™ to work properly.
