Concrete floor and laminate

[Ernesto]

Did I say use a moisture mitigation system on top of the K-15? Where?

Where did I say to put K-15 under the moisture mitigation system?
If there's no contaminants then no shotblasting is needed, you can simply scarify.

But really, what slab in a house is not going to get a floorcovering treatment? The concrete people need to start broom finishing the slabs. Everything sticks better.

Oh and you didn't copy the full text.

Surface Preparation:
Surfaces must be absorptive, clean, free from loose materials,
oil, grease, sealers, curing compounds, waxes, silicates, laitance,
and all other surface contaminants that may inhibit proper bond.
Completely remove cutback adhesive residue or other surface
contaminants by shotblasting. All surfaces to be treated must
have a profile of CSP 2-3 (similar to light broom finish), as
defined by ICRI (International Concrete Repair Institute,
Guideline No. 03732).
Surface areas requiring patching or leveling must be treated
using Durabond® Webcrete® 95, Webcrete 98 or Duralevel®
83P Fast Set patches/underlayments on top of the D-261
Extreme Moisture Vapor Barrier Coating according to label
instructions. Durabond Extreme Primer must be used prior to
the installation of these cementitious products
