National Coatings has an AcryShield Roof Management (ARM) System that allows you to create bright and stunning logo’s, murals, or any other colorful design elements you would like to add to your rooftop.

This ARM System consists primarily of our TPO A140 Primer and our custom colored AcryShield A500 Top Coat:

• The TPO A140 Primer is a low VOC, solvent based primer designed for optimal adhesion over newer TPO roofs. It has a quick dry time of one hour and provides an excellent layer of tenacious adhesion to the newly applied TPO surface for long lasting performance capabilities.
  
  
• Our AcryShield A500 Top Coat, which is the industry leading acrylic, elastomeric coating that is geographically compliant in all locations (including colder climates where extra levels of low temperature flexibility are required) exceeds ASTM D6083 requirements and includes a high performance fire retardant package. Our custom tinting technicians add color pigments to the A500 top coats to create the exact color you need, delivering vibrant colored roof coatings to match your needs.

1. Durability – How well does it resist the effects of UV degradation from the sun? In order for your roof to withstand damaging and harmful UV rays, it needs to be durable. Acrylic roof coatings are resilient, the acrylic used in a roof coating is the same that is used in exterior sealants, Plexiglas®, industrial coatings, house paints and more. They are very durable, providing excellent UV protection.
   
   
2. Low temperature flexibility – Is the coating able to remain flexible at cold temperatures? If the roof is in North Dakota where the temperatures are very cold during fall and winter, the coating must be able to tolerate movement without becoming brittle or cracking. We recommend reviewing roof coating product data sheets to ensure the coating you choose can withstand the temperatures in your climate.
   
   
3. Dirt pickup resistance – An acrylic roof coating provides excellent energy cost savings due to its ability to reflect the sun’s heat away from the building. The whiter and cleaner the rooftop remains, the better it is able to reflect the heat. Therefore, choosing a coating with dirt pickup resistance, will allow the roof to remain whiter for longer, resisting dirt from sticking to the surface, allowing the coating to perform to its fullest capability.
   
   
4. Adhesion – Coatings are created to adhere to particular roof substrates. It is important to choose a coating that is design to adhere to your particular substrate whether it be aged metal, BUR, cap sheet, EPDM, TPO, PVC, Hypalon, etc…
   
   
5. Ponded water resistance – How well does the coating adhere after long term submersion in puddles on the roof? Many roofs have areas where ponded water sits on the roof until it dries out. These areas can cause blisters, delamination and other issues if the coating cannot withstand being submersed in water for an extended period of time.

If you are looking to restore your existing roof with a material that can be renewed and sustained for as long as you would like it to last, AcryShield roof coatings are your answer.

Many people ask us “if I can extend the life of my roof by coating it, why can’t I just keep recoating at regular intervals and extend the life of my roof indefinitely.” The fact is with proper preparation and continued roof maintenance; our AcryShield roof coating systems can last indefinitely. We believe that a truly sustainable roof is one that can remain in place and offer an open-ended service life when properly examined and maintained.

Don’t worry about what type of roof membrane your building currently has because more than likely our roof coating systems can adhere directly to it. Our AcryShield products can be used on a wide range of roofing substrates including: asphalt, BUR, Mod Bit, metal, concrete, Spray Polyurethane Foam (SPF) and Single-Plies: EPDM, Hypalon, PVC, and TPO.

Once you’ve installed one our roof coating systems, we recommend you check out our 8 Step Guide for Conducting a Thorough Roof Maintenance Inspection. This list should be used twice a year (beginning of Fall and beginning of Spring) and will provide you with all the details you need to ensure a comprehensive roof inspection has been completed and your roof is in good working condition.

Our restoration, maintenance and new construction roof coating systems are all renewable and sustainable, allowing you to avoid a costly and timely tear-off forever. For more information, read our A Truly Sustainable Roofing Product article or contact us for additional information: 800-423-9557.
