I have just had bathroom tiled in greyish tiles. Intended to only part tile, now it is full tiled I am nto sure I like ti, too much grey. It has not been groiuted yet. The tiles are very matt/rough finish. I am thinking I could paint the non-bath and shower wall white in waterproof masonry paint or something? I have painted tiles before and I think tile paint is designed for shiny smooth tiles. These are very stoney in feel... Could I get away with it do you think? I am thinking that if I do it before grouting it would be ok. Thoughts please!!! Urgent.... (My tiler won't be impressed with me!!)
