molds / matte finish?

Hello! This course ROCKS! I am thinking for a while on making molds (Wood/coarse plastic?) for japanese garden lanterns pieces, with hypertufa method. How do I seal with a matte finish that kind of rough surface?

Thank you!

Glad you're digging the class!

Most types of sealant will work with a matte finish. For a very rough finish, like the hypertufa method, I'd use a few coats of exterior polyurethane spray to ensure good coverage.
