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.

Fantastic, used on a fireplace surround. Grout now looks way better.

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

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.

I was disappointed in this color. I thought it would be more of a light gray but it’s more of a blue gray. It was for freshening up our grout. It was easy to use and the paint coverage was good. Just the color was off.

Great product and long lasting.

Works great!

The video showing how it's used is a far cry from what actually happens. It looks like it should work like a felt tip marker, which would be great for getting into awkward places in bathrooms. But it's hard to anticipate and control the flow of paint, and I wound up with grey paint well outside the grout. I did more cleaning up of paint on the tiles than actually treating the grout. I thought it would be easier to use than paint brushes in difficult to reach areas, but that wasn't the case, and I'll return to using paint brushes and acrylic paint to do the rest of the job.
