I got one third of a Pergo floor laid on a concrete slab living room floor before I realized that I needed to do a moisture test (a miscommunication: I was led to believe that since the floor was 30 years old and had previously had carpet over it, then the concrete would have completely cured, etc.). As it happens, the concrete appears damp under the section that I've laid so far.
Anyway, I am faced with the prospect of tearing up the floor, or finding a way to continue and somehow mitigating the excess moisture in the concrete.
Can anyone PLEASE offer some advice on any or all of the following concepts?
(1) I could apply some sort of concrete sealant (e.g., Drylock), and continue to lay the floor;
(2) I can seal the floor as above and then lay a plywood or other subfloor over the concrete. I would sandwich the plywood floor between layers of 4-8mil plastic sheets.
(3) Seal the floor, lay a linoleum flooring, and then proceed with the Pergo.
(4) Give up entirely, write off the $400 worth of floor that's already laid, return the unused portion, and lay carpet instead.
A friend has also suggested laying rolls of tar paper / asphalt roofing material underneath a plywood subfloor.
I really need some advice desparately. As soon as I mention Pergo Presto floors to any professional floor people here in Honolulu, they won't touch it with a 10' pole (hardly a ringing endorsement).
Thanks a million if you've read this far.
