RE: 99% RH in concrete slab
Sounds to me like you used a good adhesive like mapei's new high moisture products for engineered wood. Or it was a floating click together like a tekno. All sort of options are out there

No, I do not glue down click systems. I used Bostik Best and thats all. I just had a feeling and the slab was full of spiderweb cracks in the surface so I figured the readings were artificially high due to the cracks.I was patching and you could virtually see the water get sucked out of the patch.

And it just looked dry.....OOOOOOOOH lolTongue

RE: 99% RH in concrete slab
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.

Well these were really ...lets say fractures? No? Ever see a slab with spider webed fractures or cracks? I skim coated the slab with Ardex SF. And I always patch larger cracks even when using MVP4 which they claim can bridge 1/8 inch cracks. But I've seen lots of MVP4 go down those cracks.

About those concrete contractors.....I doubt many have the technical back ground to know what all is in the mixture many recieve, so many admixtures these days. Thats another topic maybe Bob can address.

I have asked plenty of concrete contractors if they know what MVER's are, not one even knew the term so far.

RE: 99% RH in concrete slab
Got an email from a Wagner website guru the other day. He checked out my website and gave me a couple tips. That was very nice of him. He must run this forum as well.

I keep calling Mr. Wagner but he keeps hanging up on me. Big Grin
