After cleaning, using the GROUT PEN was easy. The pen went a lot further than I thought it would. My bathroom has 12x12 tiles. It really did make the whole room seem brighter.

They looked easy and were only 8 bucks, so I ordered the Winter Grey. I applied it over my unsanded grout and it immediately looked 1000x better, and it only took me 30 minutes. I was ecstatic!

This product is so awesome!! We recently bought a house and are trying to make affordable upgrades and improvements as we can. Our bathroom floors were a mess when we moved in - brown/yellow grout (not dirty just probably not sealed correctly). I was looking for a fix when I came across this. I was originally going to get white but saw the colors were different in person and decided to go with winter grey. This was the perfect color for grey tile/flooring! This is so quick to do!

I wasn't sure about getting this grout, but I based my decision on other reviews. So glad I did! It was the easiest product to use, no odor at all, great coverage, and my bathroom floor looks new again.

This stuff is amazing! My husband tiled the bathroom a decade ago, but he didn't know he had to seal the grout so it just got nastier over time. I even had a floor cleaning company come out and steam clean it and it didn't help much. It was so nasty that I was going to have it all ripped out and redone. But, I came across this stuff when looking for something else and figured I would give it a try. It turned out fantastic! It's been 6 months since I applied and it still looks perfect.
