Does the home you are looking to buy or already own have sandblasted brick? There are some things you should know to help with its longevity.
Sometimes brickwork on a home has been sandblasted to remove grime or a previously painted surface. Unfortunately, during the process of sandblasting it can remove the glazing on the brick, making them more porous. With the bricks being more porous it can allow water / moisture to wick-up into the brick. This deteriorates the brickwork faster causing spalling (brick face can come off or become / damaged) to occur during freeze-thaw cycles.
Sealing the brickwork can assist with slowing this process down, however it must be done on a regular basis, perhaps every 2 to 5 years.
