Epoxy grout has become more and more popular among tile contractors and builders. I find new benefits every time I use this product. Unlike cement grout, which is made from a cementitious powder mix, epoxy grout is made from epoxy resins and a filler powder. The grout is extremely durable and almost completely stain-proof. Regular grout isn’t waterproof, so unlike epoxy grout, it can absorb water when it’s wet and stain easily. If you’re tired of scrubbing the gunk off of your grout, epoxy grout could be your solution.
