Grout Pen Light Grey Tile Paint Marker: Waterproof Grout Paint, Tile Grout Colorant and Sealer Pen - Light Grey, Wide 15mm Tip (20mL)

Works great! Love this product! First I used on bathroom floor tiles. Refreshes the grout like new and last more than a year. Easy to apply. I also purchased a light gray for the stones in the bottom of the shower. I haven’t used the product yet. I am sure it will have to be replaced more often since the floor is scrubbed often. I will follow-up after application.

This grout paint worked great for my purpose. I had newer grout where the sealant failed and stained quite badly, quite quickly. This pen worked quickly and effectively to fix our entire kitchen floor. The narrow pen was perfect for my 1/8" grout, and I has zero issues with the tip wearing badly; this may be because our grout was unsanded so the pen glided easily over it. Based on the reviews, I elected to carefully wipe up any errant paint with a paper towel as soon as I was done with a line; doing this, the stray product cleaned up easily, but I had to be careful not to disturb the painted grout line using this method. Our tiles is glass smooth and glossy, which also made this easy. I also got the manufacturer's stated usage from the pen, but we did have the thinnest possible unsanded grout. The light gray definitely had a blue hue to it when compared to the original light cement gray grout, but it still blended quite well with the flooring in spite of this; it might look odd paired with warm-toned tiles that have no cool tones in them. Also, bonus points for zero fumes and the product being easy to prime and fairly easy flowing. Too soon to tell how well it holds up very long term, but so far, so good and I would definitely use this again, if needed.

So I ended up using 2 grout pens. This large light gray one and the small beige one. After my first cleaning of tile/grout and use of this pen I felt like the gray was too bright and it had a slight bluish hue. The last pic was the dirty tile I started with. The first pic is how it looked after I cleaned it and then used the light gray pen. The second and third pics are how it looked after I went back over the grout with the small beige pen. The two-toned contrast I ended up with is better than I could have imagined. I am very happy with the end result. My only complaint would be that the felt tips on these come out kind of easy. So you have to keep putting it back in. Other than that, i found them easy to use, long lasting, and well worth the affordable price.

After much scrubbing I just couldn't get the grout clean. It made me hate my kitchen floor! But after maybe 10 minutes I painted a good amount with this product and the difference is huge. So easy to use, the sponge at the top falls out and gets ragged after a bit but the results speak for themselves. So glad I found it!

(I'm amending my original 1-star review.) One of the pictures shows the intersection between grubby grout and the painted grout. The 2nd picture shows more of the painted grout. In natural light, the tile and the grout are nearly identical in color and depth. The grout paint is the Light Gray. The tile is a light blue color with variations that are sort of like very thin clouds drifting across the tile. If I could buy a jug of the Light Gray grout paint to use with a small brush, I'd do it in a heartbeat. The color looks great with the tile and I suspect that touch-ups would be a breeze. Alas, that is not to be. This would be great if you need to touch up unsanded grout between smooth tiles. My floor grout is very rough and the floor tile has a slight pebbly surface to keep it from being slippery. The combination of those rough surfaces basically shredded the felt tip, which is like a marker tip. It also made it challenging to wipe off the excess with a damp cloth. The excess was more and more problematic as the felt tip became fuzzier and less accurate. I decided to start in the laundry room, where mistakes would be seen by just by me . I sampled it on a few lines and let it dry overnight. Then ran my floor scrubber machine with an ammonia-based cleaner. I was happy (and surprised) that the paint held up just fine. (I've since learned that ph neutral cleaner would/will be much better for grout!) But when I went to do the entire laundry room, I quickly realized that the tip was getting fuzzy, which meant that paint was dragging onto the adjacent tile. It also took considerable pressure to get the paint to flow, despite shaking it frequently. Because the tile is rough, wiping off the excess with a damp cloth was a real pita. (I'd already checked and the replacement tips for the wide markers are not in stock, though the company said they expect them to be in within a few weeks.) Reaching the company just to find out if they *make* the replacement tips was a big nuisance. Their contact info is not on the product page. Contacting them through my Amazon account required several steps and then waiting for them to reply to my email. Overall, I would've loved the product if it came in a bottle and could be applied with a brush. There are other products that use that technique, and I found one from This Old Grout where they will match the original grout color. (I ordered a small bottle to make sure it's going to work. It requires more prep work than the marker, but I expect it to be a lot easier to apply and get good coverage.) As I started to say, though, for small areas where the marker tip will survive, this product would be fine. Too bad I'm going to have to prep and cover it with the final grout colorant!

This pen was perfect for refreshing the grout. Color was great too. So easy to use.

Nice finish, easy to work with, clean look, less mess, precise pens, wide and slim. Does not run out fast, does not require constant pumping to get it to cover. Easy to use, not messy at all. I use it on large, white tiles that get a lot of wiping off and cleaning up daily. Is not wearing it out. All the things I said are my experiences with other brands that did not work or wore out when wet a couple times, that looked a bit dull. Great product, nice color choices too.

It covers well. Dries quickly. I am doing it in sections because the grout width is less than the extra wide (15mm) but more than the 7mm width. I have to clean the excess as I go. Because it dries quickly you need to clean the excess off the tiles right away. It is is slow going but the result is very nice. Seems to be durable so far.

Easy to use. True to colour. The grout in our bathroom was very dirty and discoloured. Needed a good deep clean, after a scrub and using this pen our bathroom looks brand new and sparkling! We have floor to wall tiles and I managed to do about 90% of the room before the pen ran out. Have purchased another! Very impressed :)

Ich dachte es wäre nicht so grau die Farbe aber habe diese trotzdem dann verwendet. 1 Stift hat für das kleine Badezimmer ausgereicht, damit die schwarzen Fugen weg waren. Hoffe, dass das Ergebnis nun auch so bleibt. Vor 2 Stunde gemalert.

So easy and quick to use, lol I get compliments from my visitors 🤗

Ha sido muy fácil usarlo y el resultado es muy bueno. Pedí el gris claro y quedó perfecto. Es lo estaba buscando.

Great product, so easy to use, literally just need to draw lines through the grout, that’s it and it’s done. No harsh chemical smell either. Regarding the colour, the chart shown is what the colour looks like on the paper but since grout is a different texture, therefore the actual colour would be lighter.
