Revol Greens set out to combat seasonal growing by building greenhouses across the country, producing fresher lettuce locally with fewer resources and no unnecessary chemicals. Food safety, sustainability, and product quality drive every decision. Lifetime Green Coatings was approached for the largest of these greenhouses, a 20-acre facility in Temple, Texas, the most technologically advanced in the company's network. Built by construction firm ARCO Murray, which had seen the coating perform on previous projects, the facility needed a floor that could meet strict food-safety standards while surviving punishing daily use.
The coating had to satisfy two demanding requirements at once. First, it had to comply with agricultural regulations, with minimal exposure to VOCs (volatile organic compounds), since this is a food-production environment. Second, it had to withstand aggressive daily traffic from forklifts weighing more than 12,000 pounds. Most coatings can meet one of these demands or the other, but few can do both without cracking, off-gassing, or breaking down under load.
Lifetime Green Coatings met the food-safety requirement directly: it's completely free of toxins, VOCs, and BPA. The patented formula, made from castor oil and gypsum, meets food-safe criteria and is ANSI/NSF-61 rated for contact with potable water. It also advanced Revol Greens' sustainability goals. Castor oil is a renewable resource, gypsum is a naturally occurring rock that can be recycled in its plasticized state, and no solvents are used in application or cleanup.
Lifetime Green Coatings delivers roughly twice the adhesion of conventional coatings on concrete while staying flexible, expanding and contracting with the slab through temperature swings so it won't crack. Because the plasticized gypsum lets the coating re-bond to itself, repairs are simple and seamless, unlike epoxy, polyaspartic, and polyurea systems. It's backed by more than 20 years protecting surfaces under extreme conditions, from C-Class ferry ship decks to the inside of oil and production water tanks.

Lifetime Green Coatings is engineered for long-lasting performance, with independently tested results across the specifications above.
Revol Greens invited several coating companies to install 4-foot by 4-foot test pads to measure strength and durability. Lifetime Green Coatings installed a full quartz broadcast for an extremely durable finish, with a light flake added for aesthetics. After months of testing, it proved strong enough to withstand the daily rigors of production, and Revol Greens selected it above every other option. The project was completed to specification, on time, and within budget.
