Gain Direct Adhesion for
Hard to Coat Single-Ply
Traditionally, single-ply roofs have been the most difficult roofing membrane to adhere to due to how they physically age, break down, and the residue that remains. Typically in order to restore a single-ply roof, caustic primers, acid etching agents, or high VOC solvents are required. These harmful solutions often need to be rinsed off and collected for disposal, adding additional costs and time to a roof life extension project.
National Coatings has an alternative solution that involves less labor, less costs and greater benefits. Our AcryShield A502 base coat is specifically engineered to tenaciously adhere directly to hard to coat surfaces like Hypalon®, aged TPO, and EPDM roofing - eliminating harmful primers or etching rinses.
With a 12+ year track record of proven superior adhesion to Single-Ply the AcryShield A502 has 3 inherent advantages over previously used primers:
- It is waterborne - therefore, it does not contain any flammable solvents, VOC or fumes.
- 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 levels are 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.)
Using one of our AcryPly Single-Ply Roof Restoration or AcryShield Roof Maintenance Systems with the A502 base coat to restore your aged and/or failing single-ply roof will deliver superior bondage, excellent waterproofing, and a monolithic, seamless membrane. This new roofing system is no longer held together by seams and fasteners, instead, it is 100% seamless and monolithic, covering, sealing and protecting every inch of the roof top including areas around pipes, walls, rooftop equipment, and more. The elastomeric roof coatings are spray applied allowing every area to be filled, sealed, and watertight - even those hard to reach areas. The Single-Ply Roof Coating Systems can be applied during business hours without any disruptions or closures to your business and they will provide you with a truly sustainable roof that can be maintained every 10 plus years to avoid a roof replacement indefinitely.
