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

This really worked to cover up dried in stains in my grout. We had brown and orange stains in grey grout and this grout paint pen worked beautifully! It dried very quickly. Will buy again.

Saved my bathroom. I bought two other colors as well.

Easy to use. You just need to shake the pen a bit before using it, and the tap the point a few times.

This is made for large grout lines. Worked like a charm.

(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!

Love this stuff, works great and makes the tiles look so new , I’ve used it in both bathrooms and also kitchen, colors are great

Great produc!! I ordered 2 and had to purchase another one to do my bathroom.Its not an easy and quick fix to change the color, but when it us done it looks great. I ordered the gray to cover the tan. I learned that if you apply the pen and wait 5 minutes the gtout us completely dry, so when you clean up the paint from the tile itself the color has dried and stays in the grout lines and does not wipe out.

Good product ! It was too wide for my grout.
