The Gulf region of the United States is subjected to harsh conditions, such as scorching heat and high humidity.

All-Tech contractors began by abrasive blast cleaning the roof with to SSPC-SP6 standards, followed by pressure washing. They then applied two coats of epoxy-based primer at 2.0-2.5 mil dry-film thickness (DFT). Following the primer, the roof was finished with Coraflon ADS in Roman Bronze at 1.5-2.0 mil DFT, resulting in a beautiful finish to last over 20 years.

However, the Saint Joseph's Church roof restoration met its share of challenges. Bob Ruff, sales manager of All-Tech Coatings states, “Since the church is located in downtown Galliano, we had to be mindful of overspray. In addition, because of the soluble salts in the air; during the recoating process, the roof had to be cleaned every morning with a soluble salt detergent. Nonetheless, the Coraflon coating with Lumiflon cured correctly with no issues.”
