Natural finish impregnating sealer for interior & exterior use Suitable for all types of natural and artificial stone, unglazed porcelain, sandstone, slate, marble, terracotta, quarry, brick & concrete. Directions for use: Shake the bottle prior to use. Ensure surface to be treated is completely clean and dry. Apply with a soft cloth, brush or sealant applicator pad allowing at least two hours between coats. More absorbent floors may require further coats and on such floors the product should be generously applied. After one hour rub over the surface with a soft fluff free cloth or buffing machine to obtain a uniform finish and remove any excess sealer. This product will dry after about two hours, but will take a further three days to become fully resistant. N.B: Use in well ventilated areas. Do not use in temperatures under 5°C or over 25°C. Following application keep the area dry for a minimum of three days Always test first on an inconspicuous area, prior to general application.
