SAMPLE - Green Building Supply, Penetrating Concrete Sealer Q&A

Question 1

I think I need to seal my very old (from 1955) concrete basement floor but it has small holes (from nails that were taken out along with small amounts of concrete) that need patching. What should use to patch it with that will still allow the GBS penetrating sealer to be applied? I assume I can't patch it after applying the sealer because of adhesion issues. I intend to paint over the sealer. View answer

Question 9

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

Question 16

I applied the micro etch to concrete that had been power troweled. Afterward I found a tiny pit in the concrete (1/32"). Will these pits be sealed up and flush with the top surface of the concrete or will there always be a tiny pit? What would you recommend I do, before or after the sealer, to address any tiny pits? The concrete was previously smooth as glass and I could not perceive any pits before hand at least, but they may have been there. Should I not leave the micro etch on as long as I did? (5 minutes then scrub with a brush as the bottle suggested). View answer
