Question about sealing glass/slate mosaic backsplash?
We purchased a glass/ slate mosaic netted backsplash for our kitchen and noticed in the installation instructions it says to use a penetrating sealer before grouting. My question is what type of sealer is the best one and we worry that the glass will become hazed over since there is definitely more glass on the pattern then there is slate. I am assuming the sealer is to prevent the grout from sticking to the slate but don't you usually seal after the grouting is done also? We are confused and don't want to cause ourselves more headaches with this project. Can anyone please help us out?
