The world's greatest water-based silicon rubber sealer used for waterproofing, water resistant and anti-graffiti protection. Can be used on a myriad of materials: wood, concrete, stucco, brick, tile/grout and on and on. It is non-toxic and will not harm you or the environment. One coat resists liquid penetration and UV rays for up to 20 years. It allows the substrate to breathe, is flexible and will not discolor or fade. Resists salts, acids, harsh chemicals and oils. Can be used as a top coats for all paints or stains when mixed in or after sufficient porosity has developed after 6-12 months of UV exposure. Use Miracle cover instead of other coatings as it lasts much longer and is far more durable.
