Coating performance depends heavily on preparation. A coating applied over weak, contaminated, or improperly profiled concrete is far more likely to fail than one applied over a properly prepared surface.
Diamond grinding removes weak surface material, old coatings, and contamination, and opens the concrete to create a profile that supports coating adhesion. Skipping or rushing this step is the most common cause of premature coating failure.
Mechanical preparation is not optional detail work — it is the foundation of the floor. After grinding and repairs are completed, the floor is cleaned and prepared for the coating system.
No contractor can promise that adhesion will never fail, because site conditions, moisture, and concrete movement are outside anyone's control. But proper grinding and preparation give the coating system its best chance to perform.
