What causes brick to flake off?

What causes bricks to peel? Most spalling is caused by moisture from rain, melting snow, or damp soil penetrating the surface of your bricks. The moisture gets trapped inside, then as a result of dropping temperatures, the water freezes and expands. When the temperature does go back up, the water thaws and contracts.

How do you stop flaking bricks?
