Challenge - Aging, Leaking Metal Roof
  • Aged metal roof with several leaks
  • Rusted sections
  • Occupied business
  • Custom colors needed
  • Multiple roof levels
Solution - AcryShield® Restoration System  
  • Superior waterproofing and reinforced seams
  • RustShield A120 primers used after rust was removed for protection against future rust growth
  • No business disruptions or closures during application
  • Custom tinted coating color matched to existing building scheme
  • Watertight, leak-free hundley_hardware32-resized-219

E.M. Hundley Hardware Company's building was an aging metal roof system, over twenty years old, that was revealing inconsistent nuisance leaks to the interior sales floor. IRC specified a National Coatings' AcryShield Roof Restoration System consisting of a localized, reinforced, two-coat, 100% acrylic elastomeric custom color coating system with polyester fabric reinforcement at all metal panel end joints.

"National Coatings makes this approach feasible not only with excellent coating products but also with the wide range of accessory products from rust-inhibitive primers to individual butyl caps to encapsulate the existing panel fasterners."

- Project Manager, Mr. Rob Worthing

RustShield Provides Superior Resistance to Corrosion on Metal Roofing

Posted by Nicole Gale on Tue, Nov 04, 2014 @ 09:30 AM
Metal roof substrates are very popular for commercial roofing because of their strength and ease of application. After some time, these roofs need to be maintained because the grommets and sealants begin to weather, causing rust to develop. Over time, the rust will weaken the long term performance of the roof, causing leaks and other damage to the substrate.

National Coatings has a lasting and durable solution to solving rust issues - RustShield A120, a high performance rust primer that inhibits the future growth of rust after it has been removed in the preparation phase of application. 
RustShield A120 is a single component, low VOC, water based rust-inhibitive primer. It is used over ferrous and non-ferrous metal surfaces to provide excellent resistance to flash rusting and outstanding corrosion protection.

This primer is ideal over:
  • Metal Roof Decksnasa-1
  • Metal Side Walls
  • Rail Cars
  • Pipes and Other Metal Equipment
  • Tank Exteriors
  • Structural steel
NASA chose National Coatings' RustShield A120 product to be used on their Ares I-X rocket due to its superior strength and ability to shield against rust. RustShield allowed NASA to maintain the rocket's exterior integrity while it passed through the salty air above the ocean before entering into Space.
