moisture test, quick and effective ?

[thedoc46]

What quick and effective methods could i apply to do a moisture test on my concrete that I'll be grinding this weekend ?

I don't want to wait the 48hrs with plastic duck taped down to see if any rises.

I know some say you can do it in 16hrs... But anyway, I should have all my grinding and cleanup done by Sunday lunchtime... I'd rather know right away, if there's a moisture problem (i don't think there will be, but want to test, before rolling $500 worth of metallic polycuramine on my floor.. ) timing would mean i'd have to wait til next week before applying the flooring, if i'm forced to use the plastic test.

Generally we see problems using the plastic sheet method overnight. If you dont see any condensation or slight darkening from dampness to the concrete, that normally would give an indication that it is ok to coat.

I may just go straight in and use Rock Solid Moisture Stop.

I live in SW FL, and the water table isn't all that far down... Plus we can get some serious rain in the rainy season, which raises the water table.. So maybe i'll just go with this to be safe. Even if its dry now, that may change during the rainy season.

That being said, wouldn't the home builder of used this or a similar product on the slab? Home is only 5yrs old ??

The only one I know of is the tape the plastic down.

Absolutely not!! Good moisture vapor barrier coatings are generally only installed by professional coating people and a few DIY in the know. They are not cheap but they work, when installed correctly.

The only thing a builder might have installed is a poly-sheet under the concrete and there is really no way to know.

Here is a pic showing our version being installed.

I've been trying to buy Rustoleum's Moisture Stop just because it makes to sense given the inexpensive cost (i like to think of it as insurance !!!) , but can't find it locally for love nor money.

Is there something else that does essentially the same thing, that will not interfere with the Rock solid polycuramine metallic coating that'll be going down over it. One that soaks into the concrete and doesn't sit on top.

Our Prep-Crete Division installs large amounts if moisture remediation products so we have a lot of experience not only selling, but installing these products.

Generally speaking the floor needs to be profiled by shot blasting or aggressive grinding so that the barrier will attach and work. We would never install a vapor barrier without shot blasting. Just applying a barrier without proper prep could make this issue worse.

We would suggest you properly test the floor and not rush if you think you have moisture issues. Addressing it now us much easier and less expensive than a failure later on.

Is this aggressive enough? 8hrs of a diamabrush. and if my moisture test comes back postitive, how quickly can i get some of your barrier? and does it work with polycuraime ?
