Hello,
I appreciate your answer and your help with my learning.
I did not think there was any moisture, but how you explained this makes perfect sense. I will put down some plastic, then put something on it and let it set for a few days to see what happens.
I am planning on painting on a concrete sealer to cover spots where an old cat made her mark. I purchased a product called "Kilz" -- it is an odor and concrete sealer. We were told to put this down to ensure no other animals make their mark where the old cat made hers. The product is an oil-based sealer.
Will this make a difference?
Thanks again,
Jim
