Grout Pen White Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pens - White, Narrow 5mm Tip (7mL)

You have to shake this very well and for a few minutes to get the paint to wet the tip. Very smooth. I wish the tip was thinner yet it worked very well. Dries quick. Excess cleans easily. I highly recommend this product.

I bought two of these for my spare bathroom where the white grout had yellowed…bam this pen worked great!

This little pen is great! I have an old tub and I rent so Im not able to redo the tub and tile. This pen renewed the old stained, mildew colored grossness that was my tub. Its not perfect, but now I can step into my shower without feeling like something is going to come alive and eat me( seriously, my tub was stained black from bad caulk and mildew. One downside of the pen, you do have to press the tip down to get the paint flowing every so often, especially when doing tile above your head. Definitely listen to the instructions and make sure the area is clean and dry or it wont stick to the grout as well. It is really easy to get off of tile if youre messy like me and cant stay in an straight line if your life depended on it. Im getting another one to do the kitchen grout too because some genius put white ceramic tiles in the main entrance to the house.

I was a bit worried on getting this not knowing if it would actually work, our bathroom is very old and no matter how much it gets cleaned it always looked dirty. I decided to give this a try and I gotta tell you, I’m impressed! You can def tell the difference, & how much brighter the tiles look. I would get this again! I gave 4 stars because I do wish it was a bit more pigmented, I had to go over the lines about 2-3 times. Overall it’s a great product!

Here is a picture of a small section I’ve done on my bathroom wall. You can see it makes a pretty big difference. This is just 1 coat and it did soak into the grout pretty well. I went out of the lines onto the tile a little, so I let it dry and then wiped it off with a wet wash cloth. It came right off of the tile but stayed put in the grout, so I’m hoping once you let it really soak in well it’ll stay even after washing the wall with cleaner. The pen has the be shaken and depressed every few minutes, so that’s a bit of a pain but it works just a Sharpie paint marker. My bathroom is pretty small and I’m eager to see how much just 1 pen covers. I’ll likely buy again.

Not hard to use. Need more than one. Covers well, but the felt tip gets frayed so application becomes difficult.

This product is easy to use and makes the grout look great, but the tip easily deteriorates, though Im not sure to what extent this is a problem with its actual application.

When the package is first used, it work very well. But the applicator tip frays quickly. The tip can be removed and turned over, but it will fray quickly too. I resorted to cutting the container open, pouring the contents into a cup and using a brush to use it up. The product, once applied works very well.
