For those who are unfamiliar, epoxy grout is the better (and more expensive) alternative to cementitious grout. They last longer, are more resistant to stains, and won’t corrode when exposed to light chemicals found in shampoos. However, with so many options available in the market, it can be confusing as to which epoxy grout is the best for residential use.
If you’ve struggled with choosing the best epoxy grout for your tiles, look no further. In this article, we compile 5 epoxy grout brands that are perfect for any DIY tiling project.
General tips about epoxy grout
Epoxy grout generally dries in less than an hour. If possible, enlist the help of someone to clean after you immediately after grouting. You don’t want to leave grout on tiles for too long because it can cause grout haze which is difficult to remove. Test the product in a small area as practice and also to determine results before continuing with the project.
You don’t need to seal epoxy grout because of its durability. However, you should seal natural stone tiles before grouting to prevent grout haze. Also, while epoxy grout is more durable than cementitious grouts, you should still clean them regularly with grout cleaners or a vinegar cleaning solution.
Planning the project
How much project area can one unit of epoxy grout cover depends on the specific brand. To do so, you can either measure the amount of grout required manually or use the provided grout calculator on the brand’s website.
The difference with cementitious grout
Epoxy grout is more durable than cementitious grout, but not all epoxy grout is built the same. Some are more suitable for exposure to direct sunlight while others are more suitable for areas with extreme chemical splashes. Of course, better products come at a higher cost. The products listed below are good enough for residential applications for a reasonable price point.
