Hi,
I'm hoping someone can help as I can't seem to find a definitive answer anywhere online.
So, I currently have boring plain white square tiles in my bathroom. I have an idea in my head that I could smooth over the grout lines in between the tiles so that the whole wall is smooth, then cover it with marble effect vinyl wrap.
Is this possible? If you think it is, what should I used to smooth over the grout lines?
