Looked better than expected.
This was a perfect color match and the fact it was water proof, worked as a sealer when dry.

Tip needs improvement
The marker is good for painting grout but tip does not hold up. After third one, I learned to use a lighter touch and just over until covered

Effective, Easy to Use Grout Paint
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.

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.

A must buy!
I am very happy with this product and the three pen packet size. I bought it to renovate the kitchen and dining area grout that was very old and dark. After scrubbing the floors and cleaning the grout thoroughly, I set out to paint. It took me a full day to cover the entire area, but I could not be happier with the result. The beige color I bought matches really well with the floors I have. And the result was that the floor no longer looks like it is made of ceramic tiles. It looks like it is made of stone slab. It was not difficult to work with. Since I bought the thin tip, it was easy to keep the marker lines to just the grout. Occasionally, I would get a line slightly out of the grout, but it cleaned really well with a damp cloth. After 5 or 6 minutes, the paint dries and it is a bit harder to remove, but I had no problems keeping the finished areas clean and mess free. Others tout similar products where you need to buy a separate brush to pencil in the color. I feel that the firm tip, helped me use only one hand to both hold the product and apply it. Holding a paint can with one hand and using a brush on the other hand would have been messier for me. All in all, I feel this product is a great value. At $20+, I renovated my kitchen and dining areas with minimal mess, quickly and with a wonderful result. The other great advantage is that if I need a touch up, I can buy another pen for $8+. Who can beat that? I totally recommend this product.

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.

Excellent product.
This is excellent- wish I'd thought of it years ago! Very easy to apply and dried v quickly, completely transformed my kitchen floor tiles. All of the grouting had become very dirty, despite having steam machines, and very regular cleaning. But these took care of all the marks so so quickly, in fact my 14 year old grandson did it all!
