How diamond grinding, shot blasting and acid etching compare in profile, dust, speed and results.
Preparation is where coatings succeed or fail. Diamond grinding uses rotating diamond tooling to cut and smooth the top layer and remove old coatings. Shot blasting throws steel beads at the surface to clean and profile it quickly, especially on big floors. Acid etching uses a mild acid to roughen the surface and is common in kits. Each method leaves a different profile, controls dust differently and fits different coatings.
For most garages, grinding gives the most controllable, even surface and handles old coatings and stains. Shot blasting suits large or heavily coated floors and leaves a textured profile that needs a heavier build. Etching is low in cost and easy, but it often leaves a weak, uneven profile and does not remove sealers. Nashville slabs vary from smooth hard-troweled to rough and patched, so the right method depends on what you have. We pick the method with the coating in mind and explain why.
Even profile that removes coatings and smooths the slab.
Fast profile for large or heavily coated floors.
Light roughening that is common in kits.
Each method leaves a different texture for the coating.
Grinders and blasters have built-in vacuum control.
Prep and system are chosen together.
