What Customers Are Saying

The Mapei Kerapoxy epoxy grout is a durable and waterproof option, especially for high-moisture areas like showers and outdoor patios. Many found it easy to apply with an attractive final appearance. However, some struggled with the short working time, difficulty in mixing and applying, and the need for specialized tools and cleanup solvents. The product may be best suited for experienced DIYers or professionals tackling large-scale projects in wet areas, rather than casual home users.

Loved the end result, a bit difficult to work with

Would Recommend

I love epoxy grout for its waterproofing ability and lack of shrinking and cracking but it is difficult to work with. Dries fast and very thick. Have to move fast in small sections.
