Grout Pen Dark Grey Tile Grout Paint Marker: Waterproof Tile Grout Paint Pen Colorant, Grout Shine Touch Up & Renew - Dark Grey, Wide 15mm Tip (20mL)

I just finished my grout coloring projects today. I must say that I am very pleased with the grout pen(dark gray) so far. I purchased three pens for my kitchen backsplash and a shower wall.One wall in my shower has a dark gray grout, which in spots was beginning to discolor. I scrubbed and scrubbed, however, I could not bring the color back. I used a dark gray grout pen and colored all of the grout on that shower wall and it turned out great. It was easy to use, clean up of any excess on the tile was simple and the color looks great. See photos.Next, my kitchen backsplash. The backsplash is made up of white subway tile with white grout. The only problem is that the white grout became very dingy and yellowish over time. I used the same dark gray grout pens for the backsplash and it turned out amazing. See photos.The grout pens last a long time in my opinion. I used maybe one and a half pens for both my kitchen backsplash and shower wall. I even double coated near the kitchen sink and behind the oven for extra protection.It took me about 8 hours to do the kitchen and shower wall. My recommendation to you would be to complete your task, allow the grout to dry for an hour or so and come back to wipe down the excess color off of the tiles. With a damp cloth, the excess color wipes right off of the tiles. With a non-porous tile, you don’t need to worry about coloring outside the lines. It will not stain. Don’t wipe down after every bit of color you get on the tile, it will add so much time to your job. Wait until you’re all finished, then clean.I used microfiber towels, bundled up and damp. I worked it in circle motions through the tile wall, trying not to apply to much pressure to the grout lines. When the grout color is fresh, some may wipe off if you apply too much pressure directly to the grout. This is why I recommend waiting an hour + before wiping down. Allow it to settle into the grout. I started wiping too quickly after application and had to add some color again.After you clean up the excess color off of the tiles, examine for any touch up areas. There will likely be a few.Some reviews addressed the pen tip breaking. I never experienced this. During the color process, keep a paper plate handy to dab and prime the color into the pen tip. Do this often and you won’t need to press hard while coloring. I could see it breaking if you go all King Kong on it.I can’t speak for the durability of the product yet, but as time goes on, I will update my review. I may add a spray on tile/grout seal after a few days to help protect the color as well.

Works great!

The color was great and pen was easy to use. Again the grout tip wore down very fast and did not hold their shape while filling in the grout lines. I wish the tips were more sturdier when working around the tiles and filling in a new grout color

I used dark gray on a tiled bathroom counter. It was easy to apply, looks great, and after a month it's holding up well. Not sure if I'd trust it on a floor, but works for a counter.

While the results were good, I ended up with a lot of wasted product. This is a grout pen so I’d expect it to hold up to the rough texture of grout, but it’s shreds or flattens the tip pretty quickly. Once that happens, it becomes more difficult to get all the paint/stain out. I learned that because the tip is not even attached to the end of the pen which is somewhat problematic; it also made it possible to pull the tip out and start over on the other side. I had lots of pens I could hear liquid in that once the ends were damaged, I just could not get any more out of. I went through a lot trying different kinds of pressure to get the pen to work without damage. I’d probably have needed half as many pens if I could’ve used all the product.

We have tile in front of our living room fireplace. The grout was discolored in spots and crumbling in a few places. The dark gray was a nice neutral with the terra cotta glazed tiles. It hid the discoloration and crumbling with the dark color and make the tiles look much newer and cleaner. The marker has survived vacuuming and sweeping and still looks good. Though it is easy, it does take some time to apply. It works like a paint pen. I would limit the use to a smaller area like this one unless you get more pens.

When we tiled our bathroom floor we chose a dark grout that dried with an uneven, whitish haze and looked terrible. We removed the grout and did it again, thinking we did something wrong, with the same result. Then I read reviews online from customers who all had the same problem! Not wanting to redo the floor AGAIN, this little pen saved the day! I easily colored in all the lines and it worked great. It's been a month and still looks the same, none has worn off. So happy I found these.

Buyer beware. I read all the good reviews and thought this would be a good solution to the white grout on my kitchen floor. I scrubbed the grout on my hands and knees to make sure it was very clean. Then I rinsed the whole floor three times. I was very careful because I wanted this to work. After the floor dried I began the application process. I guess I was sloppy and it would get on the floor so I wiped as I went. After a bit I stopped wiping and decided to wipe once it dried because I was wiping away more than I was putting down. So I did about three fourths of the floor and let it dry for about an hour. Once I began rinsing the floor with clear water the dye came up off the floor pretty easily. However, in spots the dye washed off as well. So now I have grey and white splotched grout. My husband said maybe it was some sort of sealer on the floor so he sanded down one area until it was bare grout. We dyed that area, let it dry for an hour and it rinsed right off again. I’ll include pictures of the splotchy mess. I’m not sure what I need to do to fix it but I’m thinking I may need to replace all of the grout at this point. BTW, I did a test spot and that area was fine so not even that helped me.
