Hello folks! After my contractor poured 1300sqft of self-leveler onto my slab for a glue down engineered installation, I’m trying to make sure that the surface is flat prior to proceeding. I’m wondering if I’m interpreting the spec correctly. Is the spec saying that gap between the level and the floor should be under 3/16” at all points along the 10-foot span, or that the variation from one end to the other should be less than 3/16” if you, for example, push down on a teetering point? Obviously, a 1/16 drop that occurs rapidly would cause a big problem in the latter case, but not in the former. I just wanted some clarification on which is the correct interpretation. Thanks in advance!

The variation from a 10 foot straight-edge shall be no more than 3/16ths inch.
If a hump is higher than the surrounding are by over 3/16ths inch by placing the straight-edge on top of the hump, not by pressing down on the edge of a hump and measuring the other end. If there is a low spot it must not be lower than 3/16ths inch.
Address high spots first.
