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

The first time I bought this it was good and effective in covering grout stains. Second time not so much. Amazon sent what was obviously a return that they didn’t check before sending it out again to me in a poly bag; not even in the blister pack. No paint left and the tip smashed. Its being returned and hope no one else gets it in their next order. So annoyed. Hope the replacement is in better shape

I love that you can just paint over old grout and make it look new. However it does wash off pretty easily. I had just finished painting over the grout. About 3 days later I saw the paint coming off. While I was painting the marker got clogged so I had to stop my project. Order the replacements heads for it THEN finish. One pen lasted me for about half my shower. Even after two pens I still needed a third. Many spots look like they’re missing coats.

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 love this stuff! It takes the hard work of scrubbing and bleaching your grout away and let’s you spend your day doing more enjoyable things. Who wants to spend hours trying to restore their grout to that pristine white that it once was? This will help to achieve that look without any of the elbow grease or the sweat or the toxic fumes. Just draw it in the crack and walk away!! Wow! Like new!!

One pen just about finished my entire walk in shower. This is very easy to use although I can see it’s already wearing away after just a week or so. It might be good for a quick touchup here and there, but not to do an entire shower floor and expect lasting results.

In all seriousness, some reviews scared me because they acted like they used this pen on one strip of grout & it ran out. That is NOT true at all!!!! I am using these on my whole kitchen floor & they work so well and do not run out quickly. I think people pushed too hard at first and/or they didn’t try that hard to use it correctly, lol. They’re awesome & totally worth it!

I found this product easy to use. This pen is meant for grout but I used it around the seal of the bathtub. I used it on old grout & the seal around my bathtub. It made my tub area look cleaner. The seal around our bathtub overtime got dark water spots. Cleaning does not take care of the dark spots, so I used grout paint pen looks better. I did a test spot first before applying all around the tub area. I would recommend this product & will buy again.

very very bright white, if your tiles aren’t super bright white it might look a little off, but honestly a great quick fix. it isn’t as precise as i’d like, especially if your grout lines aren’t perfect or vary in depth/thickness, but overall easy to use and worked as described

The product works well.. I did feel it didn’t last as long as I thought it would.. I was working in a standard size kitchen and I have used 4 pens.. I’m not sure if this would be normal for the product or not

It was easy to use the stick and made a huge difference once applied to the grout but am disappointed it only lasted for a few months at the most.
