We are tiling our bathroom walls around the tub surround area where we will be installing an old fashioned clawfoot tub & the entire bathroom floor with slate tile. We were told that we will need to seal the slate as it a porous.
My questions is: Do I use a water based or petroleum based sealant? Which one will last longer? The stores that carry one type or the other both claim that their product is better and longer lasting. Can you help? thanks Jean & Nathan
