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

Worked great to make my front entry tiles looks brand new. Only issue I had was that the end of the marker got really soft really fast. Because grout is pretty rough the end of the marker got soft and flimsy pretty quickly making it hard to make straight lines and hard to get the grout to coat well. Otherwise was a great product overall.

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 was very nervous about using these given the mixed reviews, so hopefully this helps anyone on the fence about using them. I bought two different colors, the gray and the white. The gray definitely has a slight blue-ish cast, so if that is going to bother you use a different brand. The white is a true bright white without any ivory or yellow. Do not count on this matching your existing grout. You will not be able to just touch up a few areas. Just plan on doing the entire room. As to usage, I was pleasantly surprised by how far these went. I did the entire floor of my large master bathroom plus a little of the shower with one pen. The shower floor has small hex tile with larger grout lines so that took a little over two pens. Some tips: shake very well when first taking out of the package and any time you start working again after a pause. Depress the tip several times on to a paper plate or directly onto the grout line to get the paint flowing. Press very lightly when going over the grout. The tips lasted almost all the way to the end of my project. If the coverage starts to thin, pause and depress the tip a few more times. I would do about a 1x1 foot area, then pass over it lightly with a damp paper towel to get any overage off the tile. It is pretty forgiving and you have quite a bit of working time before it dries completely on the tile. If the tip gets too ragged you can pull it out (I used the damp paper towel) and flip it around. This was not a quick task but it went faster than I thought it would. I was worried the white would look too bright, but it just makes everything look so much cleaner. Very happy with this product!

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

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!

I used this for my bathroom floor. The floor looks great and new. Very easy to use.

very very bright white, if your tiles aren’t super bright white it might look a little off, but honestly a great quick fix. it isn’t as precise as i’d like, especially if your grout lines aren’t perfect or vary in depth/thickness, but overall easy to use and worked as described

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

Started to use this on my kitchen tile counter for about 30 min. I was excited because it looked good, however, the pen tip started to fray and the paint would barely come out, even after vigorous shaking.

I love that you can just paint over old grout and make it look new. However it does wash off pretty easily. I had just finished painting over the grout. About 3 days later I saw the paint coming off. While I was painting the marker got clogged so I had to stop my project. Order the replacements heads for it THEN finish. One pen lasted me for about half my shower. Even after two pens I still needed a third. Many spots look like they’re missing coats.
