I just mortared some very porous tiles down and i‘m ready to grout. I‘ve used these tiles before and noticed it‘s pretty tough to get the haze to go away. Should i pre-seal the tile before grouting? if so, what brand or name? Also, do i still use a grout haze remover if needed? And lastly what is your recommended tile sealer to finish the job?
Yes, yes, yes! Porous tile, natural stone, etc., needs to be sealed prior to grouting. If this tile has a smooth or shiny finish, you need to use unsanded grout so you don't scratch it. They sell commercial cleaner but vinegar and water will take the haze off in most cases. Everyone has their own preferences on sealer, but they're all about the same. Your consideration should be whether you want a shiny or dull finish. Remember, the shiny finish will be slicker when wet than the dull finish.
