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

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

I like the way the pens work initially but the points wear down and fray very fast. Then you can’t get them into the grout space between the tile

Not hard to use. Need more than one. Covers well, but the felt tip gets frayed so application becomes difficult.

Product is excellent,however, tip of pen wears out too quickly and there is ink still left in pen

Easy to use. Pen ran out fairly quickly

I used this for my bathroom floor. The floor looks great and new. Very easy to use.

You would think these geniuses could make a better product after all these years.

Easy to use

So I was going back and forth on if I wanted to do this or not and even though I’m done, I’m sure not certain if I like it better. I’m very nervous to see how it wears and washes. Over all it was super easy to work with and put on, I got the thin tip and it was still too wide, especially when the grout begins to tear up the end. Also with the white I had to go over it 3 times because it was black to begin with.

Basically, this stuff paints your grout. It does a fantastic job for about 15 minutes - then the tip becomes frayed and the paint runs out. Would give it 5 stars if it lasted longer. See my before and after photos of my kitchen tile counter. It doesnt clean up all the dirt in the cracks but does cover most of the uglies.
