If you’re planning to install an epoxy floor coating in your Dallas garage, the long-term performance of that floor depends on what happens before the coating is applied. Cracks, improper surface prep, and unchecked moisture are the most common reasons an epoxy floor coating fails early. When concrete preparation is done right, the coating performs exactly as it should for years.
Here are the three concrete prep steps that truly determine whether a coating lasts or doesn’t.
Step 1: Repair Cracks the Right Way Before a Coating
There are two types of concrete: concrete that’s cracked, and concrete that’s going to crack. Whether a slab is new or decades old, expansion and contraction will occur, especially in North Texas conditions.
Because concrete moves, cracks should never be filled with rigid patching materials. Before installing an epoxy floor, cracks must be repaired using a flexible elastomeric filler. This allows the repair to move with the slab, helping mitigate inevitable shifting instead of transferring stress into the finished coating.
Step 2: Diamond Grinding for Proper Epoxy Adhesion
Surface preparation goes far beyond sweeping or degreasing. Professional installers use diamond grinding equipment to create the proper concrete surface profile needed for an epoxy floor coating to bond effectively.
Acid etching and buffing machines do not create consistent results and often leave areas underprepared. Grinding removes surface contaminants, exposes sound concrete, and ensures the garage floor coating forms a strong mechanical bond rather than relying on surface tension alone.
Step 3: Moisture Mitigation That Protects the Coating Below the Surface
All concrete contains moisture. Before applying epoxy floor coatings, installers should test moisture levels using calibrated meters. When moisture readings are elevated, a slower-curing, moisture-mitigating epoxy primer is required to prevent blistering and delamination.
The slower cure rate of the epoxy base coat is one reason why higher-quality systems often require a 2-day installation instead of a rushed 1-day approach. Moisture mitigation protects the garage floor at the point where most failures actually begin, below the surface.
