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

Worked great to make my front entry tiles looks brand new. Only issue I had was that the end of the marker got really soft really fast. Because grout is pretty rough the end of the marker got soft and flimsy pretty quickly making it hard to make straight lines and hard to get the grout to coat well. Otherwise was a great product overall.

Cant tell you if the paint is special compared to a generic paint pen (because thats essentially what you get), but it works!

I installed white tile into my main bathroom with two large black dogs and a love of spray tan- not very smart. I felt like I was continuously scrubbing the tile and grout, i also had it pressure washed and I was just about to have someone come in and regrout the tile but thought I would give this a shot first. It takes a bit of time, but it looks so much better and is so much cheaper! It is also very satisfying to watch your progress so the time isn’t too bad.

This is working nicely. I may need to reorder to get my whole bath/shower complete. I wish they offered an tip narrower than the 5 mm.

Covered my dingy grout but tip gets worn out quickly , they need to improve the durability of the applicator.

I wasnt even finished touching up the relatively few areas of grout that had mildew stains in my small shower, and the tip became frayed and was impossible to get a precise application and even get more solution out of the tube. Update: After I submitted this review, the company contacted me right away, apologized, and wanted me to be happy with the purchase. The rep, Ashley, explained how to use the product to avoid the issues I had. If only I had known those instructions beforehand! She also refunded me the purchase price AND said shed send me replacement tips. What incredible customer service! I am changing my rating from 1 to 5 stars. I will definitely buy from this company again.

Pen application is my first choice for small & intricate work

My requirement was to brighten up 20 year old dingy looking grout .. grout that was fine otherwise ... and avoid the mess and expense of replacing the grout. My tiles are pure white glazed with a row of black around the perimeter. The Grout Pen White worked out great and the end product looked excellent. I believe I gave the product the best chance of success via industrial grout cleaner, a narrow scrub brush and elbow grease. The tip worked fine for me once i got the hang of it .. it is narrow, but as it gets wet and is dragged along the grout it sort of blossoms a bit into something like a brush .. which is good as it lets you work the liquid into sometimes uneven spots .. if you push down too hard the brush may open up too much ... wear a inexpensive rubber glove and halfway through the job pull the tip out and reverse it. If you have a tricky corner or a larger/wider than usual grout line/area save it for the end of the job and you can easily remove the top of the pen with a pliers, poor the liquid onto a paper plate and use a cheap toothbrush to apply. As my tiles are glazed any excess was easily wiped away with a dry paper towel. I cant say for sure how much area you can expect to cover .. I would think it depends on the size of the tiles and the amount of grout ... and for me I went over it a second time as some parts of the grout were way darker than others .. 2nd pass coverage was fine. I was very happy to have completed the job with a bit less than 2 pens. The test of time will tell if there are issues .. but so far it looks good .. every 4 or 5 days the floor is cleaned with Spic and Span .. and in between with a non-ammonia spray cleaner daily.

You have to shake this very well and for a few minutes to get the paint to wet the tip. Very smooth. I wish the tip was thinner yet it worked very well. Dries quick. Excess cleans easily. I highly recommend this product.

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
