Concrete brick is a durable and affordable option that is used in many building projects. There are issues with concrete’s susceptibility to water damage, however. This video explains how to use a brick sealer on concrete bricks in order to make them waterproof.
The problem with concrete bricks is that they are very porous. After 20 years or so, water and other contaminants infiltrate the brick and wear it down. The bricks become discolored and will chip easily. This is obviously not ideal for the material that is supposed to be protecting your home.
The solution is to waterproof the brick before or after installation. Instead of soaking up water and discoloring, the brick is totally hydrophobic and the water beads right off. This increases the lifespan and durability of the brick and, subsequently, your home.
To waterproof the brick, mix your waterproofing solution in a bucket. Use a small paint roller or use a garden sprayer to paint the bricks with the solution. You can do this after the bricks are put together. Make sure to regularly re-administer the solution for the longest protection possible.
