Surface Preparation FAQ

Our surface preparation FAQ covers common questions about the critical first step in any Polyaspartic or Epoxy flooring project. Proper surface preparation is key to ensuring a long-lasting and durable finish. This section explains why techniques like diamond grinding are used to create a smooth and clean substrate, allowing for better adhesion of the coating. You'll also find information on how we address cracks, stains, and other imperfections before applying the final coat.

We also detail how surface prep varies depending on the project type, whether it’s for a garage, driveway, pool deck, or patio. This FAQ helps you understand why investing time in surface preparation leads to superior results and prolongs the life of your floor, ensuring a flawless and professional finish.

Surface Prep FAQ:


What role do heavy grinders outfitted with special diamonds play in preparing concrete surfaces?

Heavy grinders equipped with special diamond tooling are critical for properly preparing concrete surfaces across various projects, including garages, driveways, pool decks, patios, lanais, walkways, and even industrial areas. These grinders are specifically designed to handle the toughness of concrete, providing precise control over the surface’s texture and porosity, which is vital for the application of thick mil coatings.

The use of diamond tooling, selected based on the hardness of the concrete and the desired Concrete Surface Profile (CSP), ensures that the surface is uniformly prepared. This preparation is crucial for promoting strong adhesion of coatings like epoxy, polyaspartic, or specialized industrial coatings, whether applied to residential areas or high-traffic commercial zones.


By creating a consistent surface profile, these grinders help maximize the performance and longevity of the coating, reducing the risk of peeling, bubbling, or premature wear. Proper surface preparation with diamond grinders ensures that every coating project—from decorative pool decks to high-durability industrial floors—achieves optimal results, enhancing both appearance and durability.
