We're almost at 3lbs MVER, so what if the rH is over 90% ?

Ok first that red text is annoying.

Second, I have heard various opinions as to what a CaCl test reads to depth wise. I think your wrong about the 1/4. When ever in a debate, change the rules. ha ha

Third, you say,

Quote:I can tell you I have seen many projects with MVER readings below 3lbs/1000/24 fail, but I have never seen a failure with a slab at 75%rH.

Then you say,

Quote:and only if the slab is properly prepared, which I have never seen.... ever).

Your contradicting yourself again. So, I take it then you have never seen a functioning floor, cacl tested properly prepared and the floor has having had zero problems. Why, because there are probably tens of millions of them you have never seen because people do not report jobs that have not failed. lol So perhaps if one only properly prepared the substrate you would not have a failure.

As far as the manufacturers warrantying the floor, I mean the people who make the rh testing devices. If your going to ballyhoo your product as invincible then put your money where your mouth is and offer to buy that floor if it fails. properly prepared and tested of course.
