Why should epoxy grout be used over regular grout?
Traditional grout consists of a cement powder mix, while epoxy grout is like liquid-plastic. Over time cement grout will absorb moisture, discolour, disintegrate and then begin to allow water to pass through. With epoxy grout there is no water absorption, no discolouration and no disintegration. Epoxy grout is 100% waterproof and stain resistant, unlike cement grout. The appearance of cement grout (sanded or unsanded) looks very natural, while epoxy grout looks shiny and plastic-like.
Epoxy grout is very easy to clean and maintain, because it is completely stain resistant. The lifespan of epoxy grout is approximately five times longer than cement grout, and is highly resistant to a wide range of cleaning products. Cement grout attracts dirt, grease and stains easily, therefore we recommend using a polymer sealer during application. Strengthening the durability of cement grout can be done by adding grout additive (grout boost), instead of water, during the mixing process.
With all those factors in mind, we always recommend using epoxy grout in areas that are consistently in contact with water or susceptible to moisture. The most popular room of the home to use epoxy grout is the bathroom, this includes the entire shower enclosure (base, curb, walls, niche or bench) and bathroom floor. Other areas of the home to consider using epoxy grout are kitchen floors, backsplashes directly behind sinks, front entrances and mudrooms.
The only disadvantage to using epoxy grout is the clean-up; this is not a DIY project that can be repaired. Epoxy grout is extremely labour intense and requires specific liquid solutions to thoroughly remove residual resin on tiles after application. With that being said, epoxy grout does cost more than cement grout because of the required materials and extra labour. Epoxy grout is a great way to ensure a completely waterproof tiled surface that will maintain its grout line colour for many years.
