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

I was a bit worried on getting this not knowing if it would actually work, our bathroom is very old and no matter how much it gets cleaned it always looked dirty. I decided to give this a try and I gotta tell you, I’m impressed! You can def tell the difference, & how much brighter the tiles look. I would get this again! I gave 4 stars because I do wish it was a bit more pigmented, I had to go over the lines about 2-3 times. Overall it’s a great product!

It’s like a marker it looks white when you do it but it goes back to the old color shortly after

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.

The felt tip of the marker fell apart when applying it to my grout between the tiles in my shower. Didn’t last more than 3 minutes before it started shredding. I wasn’t applying more pressure than normal as if I was using it as a writing utensil. Waste of money and effort.

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

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.

I was tired of looking at the greyed grout in my bathroom and I was hoping this would perk them up without the time and effort re-caulking would take, and it worked. It looks good. It was quick and easy to use and it has brightened up the walls. It feels clean and fresh again, without a painstaking full on caulk project. Now to address some of the negative comment made by others: For the tiles with cracked or missing pieces of caulk, they needed to be re-caulked. This pen was made to stick to existing caulk, it is not to be used to patch a crack or a hole, it really wont do the trick. The pen tip does get frayed but you can pull it out and turn it around and use the other side. It is not a super fine tip, so you may color outside the lines. This is not a big deal. Once it is dry, a straight razor blade will clean the edges quickly and neatly, It wont take long at all. I dont think the pen is a long term fix for high traffic areas, like the floor, the tiles that get hit constantly during a shower, or a counter top that gets cleaned multiple times a day. Those should be re-done with proper caulking. But I am very happy with the look of my refreshed bathroom and how little effort it took to get it.
