AMAZING, VERY GOOD PRODUCT TO MAKE FLOORS LOOKS NEW AGAIN
This product is amazing, my kitchen and bathroom floors over time were look old due to grout's color changed from light color to dark, after applied this product over the previous grouts with a light color such as light grey, it gave me the new and clean look again, imagine if I had to hired the floor labor in tradition way to remove and reapplied a new grout, it may cost money and time consuming for sure but this pen did an amazing job in easy way and faster compared to the traditional, more than that anyone can do it, like me an old lady with very limited strength, I never imagined that I can renew my floor myself without this product, yes I suppose to give this product 5 stars with all the features I have listed above but there is some flaws, a- not easy to clean as described, once the color settled/dried out , it's very hard to remove the excess color with water, b-the capacity length use in package may be shorter, as I had all around 40 meters medium length grout, I have used 1 large and 1 small pen with 1 layer, the two pens almost empty if not there is a little in there, therefore I remove 1 star, if you prefer more layer expect to buy more quantity

Great Fix
Was a tile installer for 25 years. There are better ways for sure, but this is an excellent fix if you are willing to maintain it. Took me minutes to do a 25 ft. bathroom with 12 x 12s. Light gray looked great. Grout looks new. Covered in 1 application

HIGH HOPES UNTIL I TRIED TO DO A WHOLE ROOM.
(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!

Both colors in photo are light grey but drastically different.
I ordered one pen to see if it would work for my space. To my delight it worked great. I ordered additional pens to finished the space, but they weren’t even close to the same color as the pen I already ordered. I then ordered other colors to try to replicate the color of the original light grey that I ordered. Nothing is close at all, so now I’m stuck with a half done room and no colors that I like to choose from.

Dunkel zu HELL
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 to use
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.
