Granite Sealer Remover
QUESTION:
I have exterior 2-1/4" mason granite mortared to a 6" pad. It was sealed with a silane/siloxane sealer and now moisture is being trapped leaving spots and some entire stones looking "wet". Any ideas why and how to remove this penetrating sealer?
ANSWER:
I suggest using methylene chloride to remove the sealer. Good thing it's outside because this stuff is noxious and toxic.
The next problem you need to solve is why water is getting underneath the granite. If you don't fix that, eventually you'll get a breakdown of the whole installation.
Good Luck,
Ryan
