Sealing Concrete.

[derekpara]

I have a shallow concrete bird bath which my feathered friends really enjoy using. Trouble is that it absorbs water quite rapidly , leaving some bathers still unwashed.

Is there anything non-toxic I could use to stop or reduce the absoption ?

Cheers. D

Any acrylic sealer will do the job.
There are many available.
See what's available where you live

As ozz has said: there are so many.
I would say that this is as good as anything..........

The difficulty is that it's hard to find out about bird toxicity.
Since this is acrylic, I would guess that, once it's dried, the seal is formed, and that should be it. No further fumes etc.

I have tried acrylic sealer, eventually I bought a large saucer at the garden centre and use it inside the bird bath.
