Example is a 16d nail hole in a vapor retarder will allow 3 pints of water through per day. That water will travel laterally in the blotter layer to affect the entire slab.
Curing compounds and sealers are a major concern to flooring installations. It is just one more thing to fail.

Curing compounds and sealers also limit the ability of the adhesive to absorb into the concrete and the ability of the moisture in the adhesive to dissipate and the adhesive to set. Adhesives between a moisture sensitive flooring and a sealed floor just won't set properly and are not approved.
