Adding a second layer of flooring or a flooring with a very low permeability will often cause a build up of moisture and a corresponding increase in alkalinity at the adhesive bond horizon.

I've seen this happen all too often. Realistically we need to be concerned with the moisture in a slab first and foremost, because with low moisture, pH and/or alkalinity is not going to be an issue.


Nice tips. Didn't get the job because either I was to expensive and the moisture testing cost. It was night work so I add more to the labor. I hate night work.
I sent them links to the armstrong site, but I guess they take the lowest bidder, not the smartest most educated bidder.

There is in fact a moisture limit JD, and I have seen this happen all over town in grocery stores and such.

Oh well, on to the next one.

Thanks all.
