ULTRA Series SIGNATURE NATURAL LOOK is made from fluorochemical polymers. This sealer penetrates deep into the concrete pavers, walls, masonry, and natural stones, thus reducing the oil and dirt penetration, as well as protecting them from the corrosion of de-icing salt. Flexlock Seal Natural Look helps prevent corrosion from de-icing salt, ultraviolet rays’ effects, motor oil & grease stains, and many other stains up to 10 years. Made from an advanced high-tech formulation, provides an invisible protection that acts as a shield. This breathable long-lasting sealer deeply penetrates the stone pores creating a water repelling seal that sets above the freezing temperature of 32°F (0°C). The seal is rain-safe after 24 hours
