I'm installing a bathroom in my basement, about 1 month ago I put down henry self level compund to take some of the dips out of the concrete floor. I could be wrong, but I don't think it required a primer. Anyway, just today I noticed some hairline cracks, which lead to me tapping and noticing some hollow spots. I whacked it few times with a hammer and it did not readily come up. I will putting down redguard and then tiling for finished floor. The affected areas are no larger than say 18 sq in. What is proper protocol in this situation? Do I have to remove all hollow areas, prime and repour. Will its present condition pose serious problems if I just continue with install? any help is greatly appreciated.
