This solvent based sealer for stone is made by Tenax in Italy and this product represents the best value for sealing natural stone in tests. It tested very good for granite (including the exotic granites), and it works on limestone, sandstone, terrazzo, concrete agglomerate, and even engineered stone. he product must be evenly applied on dry and clean materials. The presence of water, dust or dirty matter may influence the result regarding the uniformity of the surface. We suggest to spread the product using a brush, sponge, cloth or with a spray gun. Use the right quantity that the material naturally can absorb. Then, after few seconds, clean (buff) the surfaces with a clean cloth. The excess may create a superficial sticky film, so the excess must be removed immediately after the application. We suggest to repeat this treatment after 10-15 minutes from the first application. The effect of anti-stain will be achieved after 24 hours from the treatment. In case of floor application, do not walk on the surface before. Ships to the continental U.S. only.
