UCLA_HealthThe client was experiencing degradation of the substrate on their roof equipment and needed a rust preventative solution. We prepped the rusted surfaces per SSPC-SP2, SSPC-SP3 and hand tool cleaning. We removed loose mil scale & loose rust by power grinding, power tool chipping & descaling and sanded the surfaces. A base coat of Macropoxy epoxy was applied, followed by a top coat of UV protective high solids polyurethane to the exhaust pipes & air handlers. Elastomeric coating was also applied to the concrete footing of the exhaust pipe to prevent water intrusion.
