High-Preformance Metal Restoration System

The Met-A-Sil System is a premier fluid applied roofing system designed by American WeatherStar to restore and protect metal roofing systems. AWS designed the system based on the strengths of its Met-A-Sil System components: AWS Urethane 520 and AWS Silicone 410. This system starts by addressing any rust that exists on the metal panels or fasteners with AWS Rust Converter 990. Next, all seams and fasteners are sealed with AWS Urethane 522 Brush Grade Caulk. Finally, AWS Silicone 410 is applied as it offers the highest level of UV stability and water resistance available in the industry.

Rusty Panels and Skylights

Rust, also known as Iron Oxide, is formed by a chemical reaction in which iron oxidizes when in the presence of oxygen and water or excessive moisture. Iron Oxide lacks many of the structural characteristics of the original iron material and will continue to spread deeper into the material. If left alone, rust will almost always result in total failure of the panel. AWS Rust Primers are designed to neutralize existing rust as well as prevent it from advancing its damage. Skylights, if still within their serviceable life, can be renewed and restored with AWS Acrylic 230 clear liquid applied membrane.
