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

This is working nicely. I may need to reorder to get my whole bath/shower complete. I wish they offered an tip narrower than the 5 mm.

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!

I had my tiles restored by a professional and mostly what he did was paint in the grout line. Im sure (I hope) he used a better product because I paid much more for the job, than I did for this touch-up pen. He used his with a with a thin brush and a small paint can. I had some tiles on my bathroom wall that I didnt include in his job. Im glad I didnt. I was able to use this pen for the little bit I needed in the shower. I wouldnt say its what Id use for an entire bathroom, but for some touch-up around a toilet or shower, I think it was just right. Its like an acrylic marker pen. You shake and push down to eject the paint. * I write reviews to let you know how this product was for me. and to aid you in making your decision, to buy or not buy.

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!

Easy to use. Covers nicely.

One pen just about finished my entire walk in shower. This is very easy to use although I can see it’s already wearing away after just a week or so. It might be good for a quick touchup here and there, but not to do an entire shower floor and expect lasting results.

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

I like the way the pens work initially but the points wear down and fray very fast. Then you can’t get them into the grout space between the tile

My requirement was to brighten up 20 year old dingy looking grout .. grout that was fine otherwise ... and avoid the mess and expense of replacing the grout. My tiles are pure white glazed with a row of black around the perimeter. The Grout Pen White worked out great and the end product looked excellent. I believe I gave the product the best chance of success via industrial grout cleaner, a narrow scrub brush and elbow grease. The tip worked fine for me once i got the hang of it .. it is narrow, but as it gets wet and is dragged along the grout it sort of blossoms a bit into something like a brush .. which is good as it lets you work the liquid into sometimes uneven spots .. if you push down too hard the brush may open up too much ... wear a inexpensive rubber glove and halfway through the job pull the tip out and reverse it. If you have a tricky corner or a larger/wider than usual grout line/area save it for the end of the job and you can easily remove the top of the pen with a pliers, poor the liquid onto a paper plate and use a cheap toothbrush to apply. As my tiles are glazed any excess was easily wiped away with a dry paper towel. I cant say for sure how much area you can expect to cover .. I would think it depends on the size of the tiles and the amount of grout ... and for me I went over it a second time as some parts of the grout were way darker than others .. 2nd pass coverage was fine. I was very happy to have completed the job with a bit less than 2 pens. The test of time will tell if there are issues .. but so far it looks good .. every 4 or 5 days the floor is cleaned with Spic and Span .. and in between with a non-ammonia spray cleaner daily.

So I was going back and forth on if I wanted to do this or not and even though I’m done, I’m sure not certain if I like it better. I’m very nervous to see how it wears and washes. Over all it was super easy to work with and put on, I got the thin tip and it was still too wide, especially when the grout begins to tear up the end. Also with the white I had to go over it 3 times because it was black to begin with.
