Why preparation decides the job
Most adhesion failures trace back to insufficient preparation. What the profile is, why laitance has to go, and the CSP number each kind of Maverick system needs before anything is installed.

The whole point of preparation
Surface preparation is mechanically roughening the concrete to create a textured profile that is clean, sound, and free of bond-inhibiting contaminants. It exists for one reason: so an adequate bond exists between the concrete and the Maverick system. Many adhesion failures can be traced directly back to insufficient preparation, which makes this the step where jobs are quietly won or lost. The level of prep varies with the system being installed, and the exact method and equipment will vary job to job with conditions and access — but no matter the conditions or the equipment, the required profile has to be achieved before the floor goes down.
Required profile by system type
| System type | Profile required |
|---|---|
| Coatings | CSP 2 to 3 |
| Broadcast systems | CSP 2 to 5 |
| Self-levelers | CSP 2 to 5 |
| Mortars | CSP 2 and above |
| Most Maverick installs overall | Between CSP 2 and CSP 4 |
Takeaways
- Preparation exists to create a bond. Many adhesion failures are prep failures.
- The higher the CSP number, the rougher the concrete. Most Maverick installs land between CSP 2 and CSP 4.
- CSP 5 or greater means the concrete was damaged or weak — a mortar is required to smooth it before the floor goes in.
