Proper concrete preparation is key to ensuring that your epoxy coating not only looks great but also stands the test of time. Good concrete prep will have your garage floors thanking you, especially through Tucson’s intense heat and monsoon rains.
Smooth as Glass or Rough as Gravel
One of the most critical factors in preparing concrete for an epoxy coating is achieving the right Concrete Surface Profile (CSP). CSP measures the roughness of the concrete surface, which is crucial for the epoxy to bond effectively.
The International Concrete Repair Institute ranks CSP from 1 (smooth as glass) to 10 (rough as gravel). For optimal adhesion — AKA make your garage floor stick and remain unpeeled for a long time — a CSP of at least 3 is needed. Grinding is the preferred method to achieve this, providing a CSP between 3 and 4. Other methods like low-pressure water jetting and acid etching often fall short, while sandblasting can be too aggressive. We’re looking for that Goldilocks zone here.
Tucson’s local building codes also play a significant role in the preparation process. Ensuring that your garage floor meets these standards is essential for safety and compliance. Professional contractors are knowledgeable about these regulations and ensure that your garage floor installation adheres to all necessary codes.
Do it the Right Way
A common pitfall for DIY epoxy projects is inadequate concrete preparation. The specialized equipment needed to achieve the correct CSP, such as propane grinders, is typically too expensive for most DIY enthusiasts. Propane grinders are favored for their power and efficiency, despite their higher initial cost. They save time and labor, making them a cost-effective choice in the long run. Moreover, they are safer for indoor use, as they don’t require electricity, reducing the risk of electrical hazards in damp conditions, and they emit near-zero exhaust, making them suitable for indoor environments.
Don’t Cut Corners
In Tucson’s harsh climate, where extreme heat can cause concrete to expand and contract, proper preparation is vital to prevent issues like peeling and delamination. Professional contractors bring the expertise and tools necessary to ensure the concrete is adequately prepped, resulting in a high-quality, durable epoxy coating. This level of preparation helps your garage floor withstand the intense sun and occasional heavy rains typical of Tucson.
Don’t cut corners — invest in professional concrete preparation to protect and enhance your garage floor for years to come. Skip the professionals, and you might be hiring them anyway down the line when your garage floor starts to fall apart.
