99% RH in concrete slab

[eaadams]

Yes there are good adhesives out there. However, please don't think they will hide cracks. Moisture is one thing, expansion/contraction/cracks etc... is an entirely other issue that has often been the 'whipping' boy of moisture.

Cracks and slab construction type issues are interesting because now that we do have good high rH adhesives to use (almost as good as old Asbestos laden products) it will take time & education but I'm done getting sued for 'moisture' floor failures when they are really just bad 'crete. Now the concrete contractor is going to get sued (finally!) for his poor workmanship.
