A Quick and Easy Solution for Coating Aged Single-Ply Membranes

Single-Ply membranes are the most difficult roofing membrane to adhere to due to how they physically break down and the residue that remains. Most roof coatings require caustic primers, acid etching agents, or high VOC solvents that need to be rinsed off and sometimes collected for disposal, adding additional cost to a roof life extension project. National Coatings fortunately has a quick and easy solution for Single-Ply --- the AcryShield A502 base coat.  A502 allows for direct and tenacious adhesion to Single-Ply membranes without the need for a primer or etching rinse.

AcryPly_Acrylic_Diagram_-_A502_eliminated.jpgA502 was introduced by National Coatings Corporation in 2006 after three years of intensive research and successful installation, including both laboratory and actual in-service field testing. This coating was designed with self-priming characteristics that eliminate the need for additional primers or etching rinses while exhibiting a tenacious adhesion for thermoplastic and thermoset single-ply membranes, such as Hypalon, TPO and EPDM.  Previously, the only primers used for coating these membranes were solvent borne, which required warning labels, had very high VOC (volatile organic content) and required extreme care when applying to prevent fumes from entering the building.  The only other option for coating EPDM was a "prewash" or "rinseable primer" that had a very high, corrosive pH, so high that it would react with human skin oils, causing chemical burns. 

The AcryShield A502 has three inherent advantages over the previously used primers:

  • It is water borne, so there is no concern about flammable solvents, VOC or fumes entering buildings.
  • It replaces both specialty primers for the thermoplastic membranes and the corrosive rinseable primer for EPDM.  Thus there is no need for separate primer/basecoats for different types of roofing membranes.
  • Its VOC is only 0.5 grams per liter. (According to the International Green Construction Code (IGCC) the mandated maximum allowed is 50 VOC’s grams per liter.)

AcryShield A502 has allowed National Coatings to be the only roof coating manufacturer with industry leading capabilities that successfully adhere directly to aged and failing single-ply membranes with a proven and verifiable 10-year track record. The next time a project calls for coating single-ply roofing membranes, the roofing contractor, consultant or specifier should request the AcryShield A502

National Coatings knows how important it is to be environmentally-friendly and conscious of our carbon footprint. We constantly evaluate our products and ingredients to improve their capabilities of sustainability, energy efficiency and reduction of toxins emitted into the atmosphere. After many experiments and laboratory testing's, we are proud to offer both a roof restoration system - AcryPly System, and a roof maintenance system - ARM System, where each offers excellent sustainability and renewability, increased energy efficiency and conservation and ULTRA low VOC's (Volatile Organic Content).

Restoration System - AcryPly Roof Restoration for TPO

AcryPly-TPO-Diagram---VOC-Info-A502-eliminated

  • Where roof substrates are smooth, such as with an existing TPO roof membrane, an all acrylic AcryShield system may be used. 
  • Polyester fabric across the entire roof field creates an extremely durable reinforcing layer.
  • AcryShield A502 ultra-low VOC - 0.5 base coat provides unique AcryLock™ technology to tenaciously adhere directly to TPO without the need for additional primers or an etching rinse.
  • A502 base coat provides an additional layer of waterproofing, superior adhesion, and resistance to ponded water.
  • AcryShield A500 or QuickSet version A600, contain ZERO VOC's, provides industry leading UV protection, longevity and brightness. These top coats are formulated for superior dirt pick-up resistance and protection against biological attach, such as algae. 
  • A500 exceeding all ASTM D6083 requirements.
  • QuickSet A600 exceeds ASTM D6083 requirements for critical properties such as tensile strength, elongation, wet adhesion and weatherability.

AcryShield A502 Roof Coating...Often Imitated, Never Duplicated
