Epoxy grout has a reputation for being difficult to work with. With veteran tilesetter Tom Meehan's expert advice, you'll be able to master the epoxy learning curve easily. Meehan advises purchasing a kit, which includes most of the materials you need for a smooth installation. If you go a la carte, be sure to have a clean bucket, a new float, grouting gloves, mixing tools (a margin trowel and a drill-powered mixer), non-terrycloth rags, and a new sponge. Start the project by prepping properly; clean grout joints and sealed tile are a necessity. After mixing the grout, you have about 80 minutes of working time. Be efficient as you scoop, spread, and scrape the epoxy into the joints. Wash the tile surface gently by thoroughly after about 20 minutes, then wash again. Finally, buff the floor with a cotton rag, taking care to remove all sticky residue.
