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

You are increasing the porosity of the floor and letting it breathe. You are increasing the MVER at that area. BUT you are NOT grinding the entire slab, you are NOT increasing the MVER across the whole area. You are NOT testing a representative sample of the floor MVER.

I disagree. We insist on grinding the carbonation off the top if someone insists on CaCl testing.

Why?

... all concrete cracks. Therefore, any part of the slab may be exposed to that MVER in the future.
