Diamond grinding vs. shot blasting: when to use each for coatings prep
Diamond Grinding vs. Shot Blasting – Which Prep Method Wins?
If a coating system fails, the cause is rarely the resin itself. In the overwhelming majority of cases, the real problem is what happened before the coating was ever mixed. Surface preparation is the foundation of every successful epoxy, polyurea, or polyaspartic installation – and choosing the wrong prep method can compromise even the best materials.
At Chromology Florida East Inc., located at 10408 W State Rd 84, Davie, FL 33324, we help flooring contractors, general contractors, and commercial property managers make the right prep decisions before opening a pail. The goal is simple: eliminate guesswork, avoid callbacks, and build coating systems that last.
Below is the practical breakdown your crew actually needs.
Diamond Grinding
Best for:
- Smooth concrete
- Small to medium indoor projects
- Jobs requiring flatness or polish preparation
Diamond grinding is a controlled, precise preparation method that excels in environments where consistency and surface refinement matter.
Why use it:
Diamond grinding opens concrete pores, creates a uniform CSP (Concrete Surface Profile), and removes existing coatings, adhesives, glues, or mastics with surgical accuracy. It allows installers to fine-tune surface texture without over-aggressively damaging the slab.
