How to Repair a Water Leak in a Concrete Birdbath

by Jourdan Townsend

A simple birdbath is a charming addition to your garden and will attract a variety of avian specimens, to the enjoyment of you and your kids. Traditional concrete birdbaths exist in a wide range of designs, and may appear to be indestructible. Unfortunately, if your concrete birdbath is attacked by hail, blown over by a strong wind or otherwise ambushed by mother nature, it may suffer damage. If your birdbath no longer holds water, chances are good there is a crack in the bowl. Luckily, repairing it need not be difficult or expensive.

1 Remove the water from the birdbath. Some birdbaths are designed so that the bowl can be lifted off the stand; if this is the case, separate the leaky bowl and move it to a sturdy, flat surface.

2 Clean the birdbath bowl using a mild degreaser and a soft scrub brush. Some degreasers may need to be diluted with water, so refer to the directions for your particular product. Make certain the cracked area is free of any debris, and rinse the bowl thoroughly with plain water.

3 Allow the bowl to dry completely, as water trapped beneath the repair will weaken the masonry. Combine the resin and hardener in the epoxy kit in a non-metal, disposable container. Stir well with a plastic putty knife until the components are well combined, but no longer than two or three minutes.

4 Apply the epoxy over the leaky, cracked area using the putty knife. Work the epoxy into the crevice as far as possible using the edge of the knife before building up a layer of epoxy over the surface of the crack. Let the epoxy set at room temperature for two to three hours.

5 Sand the dried epoxy so that the surface of the repair is level with the concrete around it. Wipe the bowl with a soft, damp cloth to remove sanding residue, and return the bowl to the stand if necessary. Fill the birdbath with fresh water.
