Review on 🔲 Waterproof Dark Grey Grout Pen: Tile Colorant and Sealer Marker - Dark Grey, Narrow 5mm Tip (7mL) by Tony Hanson

Attention buyers. I read all the good reviews and thought this would be a good solution for white grout on a kitchen floor. I wiped the grout on my hands and knees to make sure it was very clean. Then I washed the whole floor three times. I was very careful because I wanted it to work. After the floor was dry, I started applying. I must have been careless and it might have fallen on the floor so I wiped myself as I walked. After a while I stopped mopping and decided to mop once it was dry because I was mopping more than I was putting in. So I did about three quarters of the floor and let it dry for about an hour. As soon as I started rinsing the floor with plain water, the paint washed off the floor very easily. In some places, however, the dye was also washed off. So now I have gray and white colored joints. My husband said there might have been some type of grout on the floor so he sanded down an area until it was bare grout. We painted this area, let it dry for an hour and washed it off again. I will attach photos of the stained mess. I'm not sure what I need to do to fix this, but I think I may need to replace the entire solution at this point. By the way, I did a test spot and that area was fine, so even that didn't work for me.
