Surface Preparation
Most adhesion failures are preparation failures. Concrete surface profiles and what each system requires, the three preparation methods and their removal limits, contamination and degreasing, static versus dynamic cracks, and the Maverick single-square standard for patching. Built from the Maverick Surface Prep Techline, Volume 1.
- 01Why preparation decides the jobMost 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.20 min
- 02The three preparation methodsGrinding, steel shot blasting, and scarifying — what each one does, the profile each produces, what each can and cannot remove, and the methods we stay away from.22 min
- 03Contamination, degreasing, and a clean slabFats, oils, and grease defeat a bond no matter how good the profile is. The water drop test, when to core, how to degrease correctly, and why the last pass is always a clean one.18 min
- 04Cracks — static or dynamicEvery crack gets addressed before a floor goes over it. Telling a moving crack from a still one decides the treatment, and getting that call wrong puts the crack right back through the finished floor.20 min
- 05Patching: one square, never a quiltThe Maverick standard for multiple patches in the same area — grind out to a single square rather than merging a patchwork of small ones. Plus the substrates and slab conditions that change the prep plan before you start.16 min
