Sealing a Concrete Birdbath: Non-Toxic Waterproofing

Concrete birdbaths lose their seal over time. To reseal safely for birds:

1. Clean thoroughly; remove algae and old sealant.
2. Let dry completely.
3. Apply a non-toxic, potable-water-safe sealer (e.g., Thompsons WaterSeal Clear, or concrete-specific sealers labeled safe for wildlife).
4. Follow product directions; usually 2 coats.
5. Cure fully before refilling.

See “Painting A Bird Bath” for detailed steps and product recommendations.
