What effect does surface preparation have on applying reflective coatings?

Surface preparation plays a crucial role in the application of reflective coatings as it directly influences the adhesion of the coating to the substrate. Proper preparation, which may include cleaning the surface to remove dirt, debris, and contaminants, ensures that the reflective coating can bond effectively to the roof material. This strong adhesion helps to create a resilient barrier against weather elements, UV rays, and thermal expansion and contraction, ultimately contributing to the durability and longevity of the roof system.

By enhancing adhesion, well-prepared surfaces allow for a more uniform application of the coating, which improves its performance. As a result, the lifespan of the roof coating is significantly prolonged, reducing the frequency and costs associated with repairs or re-coating in the future. This makes the choice of surface preparation critical for achieving the desired outcomes with reflective coatings.
