Perfect
I bought this product to refresh the grout in my bathroom, and it worked perfectly! It was incredibly easy to use and gave amazing results—my grout looks brand new. I’m so impressed that I’ll definitely be purchasing another color to update the grout on my kitchen countertop. Highly recommend!

Easy To Use Grout
This is an easy way to repair missing grout or to grout replaced tiles. The grout applies easily and quickly. It can be recapped for additional use later on. It cleans up easily, and is so much better than using large tubs. Good value and great performance.

Easy to use good results
This was the only tube type touch up grout I could find in the color I wanted to match the color of my bathroom grout. I’m glad it was, I used it to touch up the grout around my bathtub. Easy to use just follow the directions, it came out perfect.

Title: Color Does Not Match the Photos – Be Careful Before Opening
I was very disappointed with this product. The color I ordered looked completely different from the photos shown on the listing. After opening and trying it, I realized it was not even close to the color I needed. Because it was already opened, I could not return it, which means I wasted my money.I even ordered a second shade that looked similar in the pictures, but again, the color was way off. This made the product unusable for my project.Please be aware: once you open it, you cannot return it. I also hope the manufacturer can adjust the color chart more accurately, especially for the gray shades. The gray I received was too light with a bluish tone. If the company could match it closer to the popular modern grays, it would be much better for customers and for the brand.

Easy to apply
I've applied a good amount of grout in my days and have yet to find anything like this easy to apply and wipe. When your done it's a professional look.
