A friend is remodeling a 1700's house with hand stacked stone walls. They have exposed the stone in the shower wich will also serve as a steam shower. The stone has been newly pointed and now they are looking to seal it. Any ideas on what to use? They are conserned with the sealent fogging or clouding due to the steam and heat of the water pounding on it constently.
Any help or suggestions would be a great help.
