Mapei Grout Refresh Colorant and Sealer: Grout Paint and Sealant - 8 Ounce Bottle, Acorn

Appling it was easy, using a small paint brush. Removing it was more challenging. I used a wet rag, but timing is everything! Too soon, and you remove more than you should, resulting in having to reapply. Wait too long, and you have to scrape it. But, when the timing is just right, it's easy and no touch up is required. So, I recommend trial and error early on in the process. Once you figure out the timing, it's a snap.

Easy to use and a quality product.

After drying it was 2 shades to light, had to go to home depot and buy a different brand darker than I wanted to tone down the color.

Nope. Very weird, gummy texture, impossible to make aesthetically pleasing. Get the kind you brush on instead, don’t waste your time
