Mapei Grout Refresh Colorant and Sealer: Grout Paint and Sealant - 8 Ounce Bottle Bundle With Brush, Pure White

This product delivered great results, but there's definitely a learning curve involved. If your tiles aren't very glossy, I would hesitate to recommend it unless you're prepared to invest a significant amount of time in the project. The product adheres well to grooves, but be cautious—if you apply too much on the grout, it tends to lift. I found that using a thin layer and staying within the lines as much as possible was key, even on smooth tiles. Overall, it did an excellent job with just one coat and some spot checking. The white color is truly vibrant, which I appreciated. However, I strongly suggest purchasing a razor tool for cleanup, as the blue soft plastic tools didn’t work for me. Only a hard plastic or metal scraper was effective. In the end, the results were worth the effort, but it requires precision, the right tools, and patience.

Very pleased with this product I’ve lived in my house for 25 years. and consider myself an extremely clean person. This is a result of aging of the grout and this product brought it right back to life.

I used this on my bathroom floor The ease of applying it on the cracks went well Using the brush helped with the application Now looks like a new tile job!

This product was supposed to cone with a brush. There was no brush in the package. Also, it took forever to get this product! I want the brush!
