I used this around the shower where the grout had become discolored. It covered most of the marks and didnt wash away during the first few showers. So far it still looks pretty good.
The color covered most of the yellow stains.
It was easy to hold and the tip fit the grout lines well. The paint dried without leaving much odor.
Simple to use once the tip is primed.
I used one marker on a small tiled bathroom floor. It covered more area than expected but started fading near the end. For a larger room I would definitely order more than one.
