Does exactly what its advertised to do but make sure you actually have WHITE grout before using it, otherwise your results will be freakishly bright. Wish they made these in other colors, like pale grey and beige...

The first time I bought this it was good and effective in covering grout stains. Second time not so much. Amazon sent what was obviously a return that they didn’t check before sending it out again to me in a poly bag; not even in the blister pack. No paint left and the tip smashed. Its being returned and hope no one else gets it in their next order. So annoyed. Hope the replacement is in better shape

I used this product 5 years ago in the bathroom floor of a house we bought. It had beautiful beige tile and hideous orange grout. After cleaning the grout with a paste of Oxiclean, I applied the pen. It covered completely and I have beige grout. It has lasted without reapplying for 5 years. The floor is washed every week. We recently bought a vacation condo with beige tile and orange grout in the shower. I used the white pen and the shower looks brand new. Now I ordered more for the floor

Initially I had trouble getting the pen to work. After a bit, I was able to get it going. Hopefully now that I have used one and know what to do to get it started the next one will work even better

easy to use but the end brush flatten out quickly

It’s like a marker it looks white when you do it but it goes back to the old color shortly after

I bought this product at the recommendation of a neighbor who has the same old tile floors in her condo. I didnt want to spend a ton of money to replace my bathroom floor so I gave this a shot. I originally purchased 2 pens thinking that would be enough. I went through the 2 pens after doing half of the floor (you can see my bathroom size in the photo). I ended up ordering 3 more. In total I ended up needing 5 pens for my bathroom floor. Depending on the condition of your floor, the process of painting between the tiles can be long and tedious. Mine were in rough shape and needed 3 coats to cover the old grout. It took me approximately 6 hours to finish which I did in increments (2 hours for the first coat then let dry, 2 hours for the second then let dry, 2 hours for the third). I had the TV on in the background so it wasnt bad. I had to get in a rhythm of shaking the pen and gently pushing it on the tile, but once you get the hang of it, its easy. Do not press hard when applying it or you will crush the tip. The only negative thing I could say is that I wish the consistency of the paint would have been a bit thicker so I didnt have to apply so many coats, but otherwise, great product!

Product is excellent,however, tip of pen wears out too quickly and there is ink still left in pen

I wish the tip was longer so I didnt have to be pulling everytime. Other than that, it did what it was supposed to. Would buy again.

My landlord didnt want to redo the grout but it was so aged from years of renters. This group pen saved the day! My bathroom looks brand new!
