 AcryShield A550 a Durable Roof Coating that Provides Superior Protection Against
Foot Traffic and 
Physical Abuse

A550 offers added protection for those area's where extra foot traffic and other
wear-and-tear is likely to occur - specifically near the roof hatch, HVAC systems and other equipment on the roof top

AcryShield A550 is an acrylic elastomeric top coat that can be applied as a multi-purpose base and top coat. This coating has double the toughness of any other AcryShield coating. A550 offers urethane-like qualities with two to three times the level of elongation and tensile strength of our standard roof coatings.

A550 provides superior protection against foot traffic and physical abuse. A550 can be applied over a variety of substrates as a top coating including BUR, Mod Bit, Asphalt, Hypalon, EPDM, TPO, PVC, Spray Polyurethane Foam (SPF), Metal and Concrete. A550 can also be applied as a base coat over SPF and Metal substrates.

A550 exceeds ASTM D6083 requirements for critical properties such as tensile strength, elongation, wet adhesion and weatherability
