This product worked great on sealing my glass block wall. I cleaned the glass blocks with regular window cleaner. I applied two coats on a non-windy day, allowing drying time between them. The next rain...not a drop of water leaked into the house!
this repellent is the best. The multi surface aspect is wonderfull . This stuff works on anything !
I proofed a cab for an atv and now staying dry as hot sand on miami beach. One 12oz. can will
do quite a large area. The aerosol can is very convenient to avoid messy cleanups.
