Repairing deteriorating brick

If the face of the brick has burst off, that is the result of water penetration. In the winter, that moisture freezes and expands causing the brick face to burst off. The source of the water penetration must be found and corrected. It could be a bad gutter or downspout, a leak in the roof or the lack of a drip edge. Once the source is found and corrected, depending on the amount of damage one of the following options will work:

• If the damage is spotty and only a few brick, those can be cut out and replaced with reclaimed brick. The current brick can even be cut out and turned around so that the backside, that was not exposed to the elements faces the exterior.
• If the brick damage is spotty, the brick can be brushed clean of loose material and there are sealers that can be applied to protect the brick.
• The third option, and the last resort, if a majority of the brick is damaged, is a bonding agent that can be applied to the face of the brick and then a mortar repair made to smooth the face of the brick, after which, the brick can be painted with a good quality paint.
