Few things are as frustrating as discovering that your once-flawless brick wall or foundation has a chip out of the side. Replacing a single brick that has been placed in a structure is a big job. Instead of going through this hassle, you can glue the chip back into place.
Clean both the brick and the brick chip with soap and water. Use a power washer to clean the brick within the structure if it's exceptionally dirty. Allow the brick to dry overnight, as it is porous.
Run a dry cloth over the exposed brick to remove any dust that may have accumulated overnight.
Coat both the area where the chip came off and the chip itself with construction adhesive. Use a glue roller to ensure even coating.
Press the brick chip into its niche in the brick, fitting it into place. Hold it in for at least 30 seconds until a bond forms and the pieces stick. Wipe away any oozing glue with a damp rag.
