No one could possibly predict what the slabs MVER will be in the future, the reading is prior to installation, wrong again.
I know what I'm talking about here, this I can guarantee you. You call Bostik and ask what their position will be if you put their glue down on a 70% floor or a 3 lb floor with no vapor retarder and if in two years the floor becomes 24 lbs MVER and 99% RH... Ask if they'll warrant that installation because it was good before... LOL.
And I know what OR means. If you have no vapor retarder, OR a failed vapor retarder, OR more than 12lbs MVER, OR more than 82% RH, you cannot use our product... That sure doesn't mean you can pick any one of those conditions...
