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

This product is great. Simple to use. The tip works & holds up really well. I have wide grout lines that were black but have faded to grayish. Photo doesn’t do product justice. Grout looks new. I have chocolate color grout in an another room. Will be freshening that soon. Easy clean up too.

Why did you pick this product vs others?:Great product! I used it to give my fireplace tiles a face-lift from dirty white to black. It got the job done and it looks amazing. Ps. I tried a black permanent marker to see if it would have the same effect and it doesn't!

I liked that it was TRUE BLACK. It went on black & dried black in minutes. Doesnt smell and the single large pen was enough to complete my entire counter top grouting. Couple of "could be better" things. The large tip is very big. (1) If they just included the smaller tip it would be perfect. Suggest scraping away any excess grout before it dries, otherwise you may have to scrub for clean lines. (2) They should include cleaning steps for excess or grout spillage. Its washable, but with some effort. After first attempts , I ended up using the large tip.on its side. It dried true black quickly (photos), but I definitely recommend waiting the 6 hours before getting tiles wet.Bottom line: I am happy with the results. I would buy the smaller tip pen for any tiles smaller than 10x10. My tiles are 12x12 and the tip was even too big for the grout lines. Finished grout looks clean & definitely black. Would recommend.

Great value , seals completely, covered and looks perfect!

Our black grout has never been black, even when it was first installed. I was hopeful this would help cover some of the efflorescence and discoloration.The color of the marker was nice, it instantly refreshed the area I tested. However, the product does not go very far at all, especially on large floor tiles. I was not even able to finish a small closet. The tip also wears down really quickly, even without pressing too hard. The marker is better suited for smaller areas or backsplash tiles, something like that. It's definitely not a cost effective option for 2,500 sq ft of floor tile.

I was looking for a way to update the backsplash in my kitchen. The grout pen is super easy to use & cleans up well if you make a mistake or get any on the tile. I purchased 3 for this space. I went through two pens and a bit of the third and now have it to use for touch ups if needed. I plan to purchase another pen for the tile in my bathroom!

There is not much in this pen. I bought the fine point one and it was still thick. Wish I didn’t start it.

Used dark grout and had white appear where crystal formed from the water. Used this and my grout, on the floor, looks great. Used in bathroom, and it's a few months now and still looks good! Made all the difference!
