My project is replacing mortar joints in a brick patio atop a concrete garage. Years of leaking created stalactites in the garage ceiling creating a real cavern appearance. After applying 2 coats of Armor SX5000 silane siloxane sealer, the water would bead up on the brick like drops on a waxed car hood. The joints were sealed as well judging how dry the garage stayed after 30 minutes of hosing. I laid tile on my countertops and backsplash and plan to seal my grout joints with this. Milky water appearance and light viscosity makes it easy to apply and dries clear
