My shower was a boring gray tiles with random turquoise flower pattern. I was looking for a permanent solution to make it look brighter. Tiles ( adhesive) were not an option so after a search online I was able to find this idea of painting tiles. So I did. No regrets!! I had to use 3 kits as it was not covering enough of the pattern and the color, even though it was a light grey. Be aware that once kit covers just about 2 coats on 2 wall shower and one coat on 1 wall shower. So, so 2 kits is enough for 4 coats, depending on the color your shower was before. The first coat is easily scratchable so be careful; hense , several coats are necessary. Easy to apply...LET IT DRY . I waited a good week before I use my shower and let it cure. Be patient. The more you let it cure, the better it will dry.
