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

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

What is the Best Coating to Use for an Aged TPO Roof?

Posted by Nicole Gale on Tue, May 27, 2014 @ 08:00 AM

TPO roofing has been known to be one of the hardest, most stubborn substrates to adhere to. Most roof coating manufacturers require an initial primer or etching rinse to be done before applying a base coat to the TPO membrane. Unfortunately, this adds additional labor time and costs to the roof coating project. National Coatings has made it a point to focus a majority of their efforts on providing durable, waterproofing solution to the roofing community that surpass their competition. With this goal in mind, National Coatings created the AcryShield A502 base coat, which DIRECTLY adheres to aged or failing TPO roofs without an additional primer or etching rinse.

TPO Roof

The AcryShield A502 offers the best solution in the roofing industry for restoring a TPO roof because of its ability to tenaciously and directly adhesion to the TPO membrane. The A502 base coat eliminates the need for a costly roof replacement, lowers project costs and increases job efficiencies. There is no need to capture caustic contaminated water from the primers and etching rinses, which a majority of municipalities require. This provides safer work conditions and is better for the environment.
