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

Wasted a lot of it just trying to get the paint on the vertical bath tiles. It would work better for flat surfaces. Gave up and bought a brush and enamel paint. However, I used the thicker tip for the bath floor and that worked well.

I like this product it works really well on the grout; however, it’s a little pricey for how much area it does

This is one of those products that has a lot of upsides but several downsides. To preface, I have a roughly 20-square-foot white tile floor in my apartment bathroom. When I moved in, the grout was very discolored and made the tile look dirty. I was extremely skeptical about this product, but it was a reasonably priced solution and a top seller on Amazon, so I gave it a shot. I followed the very simple directions on the pen (clean floors, remove cap, shake pen, use), and was initially amazed by the results. My nearly gray tile grout was being transformed back to white. Although, after I got through about 6 square-feet of tile, the pen tip started to fall apart. Was it still usable? Yes. Did it hinder the quality of the paint job? Also yes. Additionally, the paint ran out much quicker than expected. I was able to get a single coat on the entire tile floor, but the 60 meters of coverage they claim is a little far fetched. Nonetheless, my tile floors look good. A couple tips (no pun intended): get two pens because the coverage is less than advertised, apply 2 coats, REALLY clean the floors before you start (I didn’t deep clean nearly enough and the grime made the paint job much harder), consider another solution unless you have white tile as well (I feel as if this pen would not be great if you needed to be precise), and don’t push as hard on the tip to increase the pen’s longevity. Hope this helps! Still a good product, just a couple things to keep in mind before you buy.

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.

I found it very easy to use and it instantly refreshes old grout lines to look like new! I used this on our white tiled kitchen counters and island, the area that gets the most discolored from food. I used to use white paint with a small paint brush to refresh the grout in the kitchen, but that would take time and start to peel off and not last that long. If chunks of grout actually came out (rare), I assume Id need to mix some grout and fill it with that, but for discolored tile, I just quickly use this on top of my old discolored grout lines, and its fantastic, I would buy this again for my needs. it probably helps that the tile is white too, but if i go over the grout line onto the tile, it easily comes off the tile. I just got this pen, so i couldnt review the longevity or easy to remove yet. I also dont know how this would work in the shower where water gets on it all the time, our shower tiles dont have white grout and arent discolored. But for the kitchen with white tile and white grout, its so far ideal!

I used this product 5 years ago in the bathroom floor of a house we bought. It had beautiful beige tile and hideous orange grout. After cleaning the grout with a paste of Oxiclean, I applied the pen. It covered completely and I have beige grout. It has lasted without reapplying for 5 years. The floor is washed every week. We recently bought a vacation condo with beige tile and orange grout in the shower. I used the white pen and the shower looks brand new. Now I ordered more for the floor

Covered my dingy grout but tip gets worn out quickly , they need to improve the durability of the applicator.

Does exactly what its advertised to do but make sure you actually have WHITE grout before using it, otherwise your results will be freakishly bright. Wish they made these in other colors, like pale grey and beige...

I really liked the pen when I did the first 3 square feet of tile. However it is not long lasting. It started to dry out after I had done only 1/4th of my countertops and once it was drier, the tip frayed. I liked it enough to buy a another to finish the kitchen however the second did not allow ink to flow as smoothly as the first. It didn’t cover the grout well like the first 1/4th of the kitchen and frayed even faster.

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!
