Simply put: Moisture + salts + a sealed surface = hydraulic pressure that pushes the coating off the slab.

Gauge uneven surfaces with the confidence of 4 points of contact. Stainless-steel gauge rake body that accepts four interchangeable Skid Gauges designed to work at varying angles instead of just perpendicular and also be more forgiving of a rough application surface at depths of ⅛ – ⅜ in. (3 – 10 mm) across a full 24 in. (600 mm) path. See more at Portamix.com for a range of levelling tools.

This is one way to find out. 😁

They only call out ASTM 2659, that’s moisture meter guys. Here’s what it says: Although this floor is waterproof, from the top down, it is not to be used as a moisture barrier. The subfloor must be dry. Concrete moisture vapor emissions should not exceed 2.5% moisture content (ASTM F2659 method). Prior to installing flooring, remove dirt, paint, varnish, wax, oils, solvents, any foreign matter and contaminants from the subfloor. Do not use products containing petroleum, solvents or oils to prepare subfloors as they can cause staining and expansion of the new flooring.
