Although it has plenty of benefits, note that epoxy grout is more difficult to work with than regular grout. It also tends to look like plastic, which some homeowners don’t like. Regular grout is very easy to shape in outside corners where tile wraps around a wall, curb or shower niche. It is harder to achieve the same effect with epoxy grout, since it takes a little longer to set up in the grout joint.
Epoxy Grout Implementation
- The caulk may not exactly match the grout color.
- Even when the caulk exactly matches the grout color when installed, it may not match six months later (caulk will “age” differently from the grout).
- Caulk will need to be maintained more often than grout.
- Mold may grow more easily on caulk (except caulk treated with mildewcide) than on grout.
- Acrylic caulks break down in horizontal wet applications. Silicone, urethane, or multi-polymer caulks are better choices but can be harder to apply.
