Anaheim, CA – The South CoastAQMD facilitates air quality monitoring stations throughout Southern California. Most look like this storage container. These off-site offices hold weather sensitive air quality monitoring equipment and computers. These offices are always active and occupied intermittently for monitoring and testing of air quality and gathering data for testing. This expensive, high-tech machinery must be protected from heat as well as water.

This air quality monitoring station and four others have been restored over the last year using SureCoat and a SureCoat Approved Contractor. These containers were covered in rust because standard paints and coatings used in the past were unable to stop the oxidation process that leads to rusting.  You can see from the picture that the rust bled through the paint as it continued to degrade the metal.

Metal roofs and containers are extruded and anodized or painted at the factory before they are installed in the field. The baked on coatings have not provided any energy-saving benefit in the past. Most worn metal roofs have been neglected to the point that rust is evident. There will be missing fasteners that have come loose through the thermal cycling process and popped off. Beyond the surface rust, there are often holes in the metal where the roof has rusted through. Often these roofs are not attended to until there is a leak and multiple issues present.

Regular exterior paint and acrylic roof coatings cannot hold up to the constant thermal cycling, heat, UV radiation exposure. In addition, the preparation work required to paint metal is extensive and often includes primer coats, rust inhibitors, and several topcoats. All the work the contractor is required to do will not add any integrity to these paints and coatings. The oxidation process that causes rust is not stopped because water can still reach the metal as moisture permeates through paints and acrylic coatings. Rust will appear from under the paint or coating proving the degradation of the metal has continued.

In addition, sheet metal used to make HVAC duct work and plenums will also rust if left unprotected. HVAC duct seams, roof jacks and other metal flashings are often sealed with black and gray mastics. These mastics absorb heat, become brittle and split in a short period of time and need constant maintenance to keep the seal watertight.

The SureCoat Roof System coating material is an excellent product to seal metal seams and to protect sheet metal from rust. The elastomeric, monolithic, waterproof membrane adheres to all types of metals including factory coated metal, galvanized, bonderized, mild steel, sheet metal and aluminum. The SureCoat Roof System forms an elastomeric, seamless, protective, waterproof membrane over the roof field that moves with thermal cycles.

Without water and air, the oxidation process is interrupted so rust no longer forms on the metal.

Exposed duct runs can be sealed to keep the heated or cool air from escaping through the seams. SureCoat Roof System material emits 93% of the heat which will keep cold air from heating up as it passes through the ducts in the summer for better efficiency and lower cooling costs. The lowered demand on the HVAC system may help to extend the life of the equipment.

SureCoat is Field-Tested™ and Proven to be the most effective metal restoration coating available for commercial, industrial, manufacturing, storage and maintenance over metal.
