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

The white liquid inside the tube is very good, but it this product as it comes, is very hard to apply to the grout. The little brush as the end of the tube, very quickly breaks down like a tiny paintbrush that got squashed, and then it is of no use at all. I was able to take a ballpoint pen and take it apart and use the ink holder part, to insert it into the tube and force the release of the liquid (to leach out the white liquid) and apply it that way. It did a pretty good job, but it was a tedious process. It also takes several applications because the liquid springs back into its shorter application area and then needs more liquid to be applied to reinforce the area that I already applied. I believe that the application tip should NOT be a brush, but it should instead be a solid piece of plastic to apply similarly to an old fountain pen. That would be similar to the applicator of a Tide Pen (R) for getting out stains on fabric. I believe that that would work much better to apply the liquid to the grout.

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 installed white tile into my main bathroom with two large black dogs and a love of spray tan- not very smart. I felt like I was continuously scrubbing the tile and grout, i also had it pressure washed and I was just about to have someone come in and regrout the tile but thought I would give this a shot first. It takes a bit of time, but it looks so much better and is so much cheaper! It is also very satisfying to watch your progress so the time isn’t too bad.

This product works well for its purpose (covering up faded grout) but my main complaint is that the tip quickly becomes useless, much sooner than the grout pen “ink” is used up. Even turning the tip around to get a new sharper edge doesn’t make it last long enough.

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.

If you want to touch up a few tiles this is fine. Anything bigger and you will probably not be happy with this .

This pen worked nicely for touching up, but I was not able to finish the job because the tube ran out before I got to the shower seat. I would say you need two tubes for retouching a shower floor. It has not been six hours so I have not tested it fully. Looks nice now.

The felt tip of the marker fell apart when applying it to my grout between the tiles in my shower. Didn’t last more than 3 minutes before it started shredding. I wasn’t applying more pressure than normal as if I was using it as a writing utensil. Waste of money and effort.

Not crazy about this product. Not sure what I was expecting, but not this. It doesn’t clean, it just covers like shoe polish. Would not buy again.

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.
