Providing Commercial and Military Grade Epoxy Coatings along with Grout and Stone Sealants. We install the highest rated products available in the U.S. Our Military Grade Garage Epoxy is used by every branch of our U.S. Military and is more than 5 times the thickness of DIY products and superior in adhesion and protection of concrete surfaces than any other product we've found. Diamondback Coatings also specializes in sealing and protecting tile grout and natural stones. Our epoxy grout sealant lasts up to 15 years per manufacturer and is recommended in high traffic areas of your home. This sealant is actually a grout colorant and while it seals and protects NEW tile grout it can also bring new life back to old and discolored grout lines. Our clear stone sealant carries a 15 year written warrant and actually impregnates into the surface to protect from the inside out. Other clear sealants simply seal the top of the surface and dissipate and stop protecting after only a few short months.
