Question 9

Hi - I created a new birdbath out of concrete that has imprints of leaves on the inside. I want to seal the birdbath including the inside that will hold the water. Is there a sealer that I can use that will be non-toxic to birds? I understand that the PH will be high on fresh concrete and that there are products that can reduce the PH of the concrete before sealing it. Will that be necessary before using the sealer? Although the birdbath is large (~ 2 x 2.5 ft.) I believe that I don't need a full gallon of the product. Can I get it in smaller sizes? Thanks, Steve View answer

Question 37

I have a basement with a poured concrete floor and block walls. I also have a radon issue. Radon mitigation has been installed and is providing good evacuation of the air under the slab BUT i believe that the unsealed block walls are "leaking" enough air to bring some radon into the space. Will treating the walls with GBS seal the walls against any airflow and hence the radon that would be carried in with the Air? View answer
