Sealing/painting cement slab for humidity?
I think it would be a waste of time. First, floors should never be painted, if anything slabs can be stained. Paint will wear off and can peel in some circumstances. Paint will do nothing to reduce humidity. If you have high humidity your Dricore underlayment would work either. Did you read the Dricore info well?
