Epoxy grout is made from epoxy resins and a filler powder. It is extremely durable and almost completely stain-proof. It offers extra layer protection to the tiling making it more versatile than regular grout. Regular grout, on the other hand, is made from a cementitious powder mix. It is not waterproof and can absorb water when it’s wet and stain easily1.
The difference between epoxy and regular grout is the strength of the bond they create. Epoxy is stronger than grout but it also sets faster. Grout will have a longer working time but it won’t be as strong as epoxy2.
In summary, if you are looking for a more durable and stain-proof option, then epoxy grout is the way to go. However, if you are looking for an option that has a longer working time and is easier to work with, then regular grout would be recommended1.
