Brick sealant
As discussed briefly in one of my blogs, a good way to protect your external walls from water penetration is by the use of a brick sealer. I have had good results from the Ronseal product listed below, its easily applied by brush or roller and quickly makes the brickwork your painting it on water resistant. DO NOT get it on the windows though its really hard to get off.

Another option now though is to use a water sealer that still allows the brickwork to breath, so its stops water penetrating but still lets moisture out and the brickwork breath. This is a good option if you have had brickwork that’s been saturated for years. If you coated this up with a product that doesn’t allow the brick to breath you are in essence sealing in the moisture already in the brick work which could cause problems and in fact push the moisture into the building more so. See link below to amazon where yo will find the breathable equivalent.
