To prevent water absorption and related damage such as freezing and cracking a waterproofer can be used on various exterior surfaces to protect and prolong their life.
Apply multi-surface waterproofer with a spray to concrete birdbaths, terracotta pots, wooden birdhouses and feeders, and paper maps. Let the treated surface dry for 48 hours and know they're sealed when the water beads on the surface.
