I need recommendations on the best exterior sealant for our brick patio walls.
I have noticed the last few years a build up of salts on the bricks on the inside of my patio. I have assumed that was an indication of moisture coming through. During our very recent experience with hurricane Isaac and the constant and long lasting wind driven rain, we had significant issues with water on our patio. Our roof wasn't leaking, but the water was definitely coming through where the windows meet the brick and, we are pretty certain, also at the foundation. We thought the window/brick joint had been sufficiently caulked, but apparently not. Would putting a sealant on the exterior of the brick keep moisture from coming in that way? There are so many different sealers out there. Can someone recommend one that would work well for this situation without changing the color of the brick (a slight darkening would not be an issue)?
