Has anyone ever done this? I can't believe I'm thinking of taking this project on.
I have a ceramic tile floor in my entrance that is adhered very well to the floor. The tiles are shaped like your average bricks, and they are a beige that is a bit yellowy and greenish. It appears to me as though the original grout was painted over in a very dark brown. Because of the contrast between the dark brown and the lighter tile, there is a lot of pattern from the gridlines on the floor.
If anyone has used a paint product with success for floor grout, I'd love your recommendation. It's my hope to be able to tint a suitable paint to almost match the colour of the tile so that there is less pattern. (trying to make the floor fade into the background, you know?)
