Elastomeric traffic coatings should conform to which standard?

• A. ASTM C957
• B. ASTM C920
• C. ASTM D6083
• D. ISO 9001

Answer: (A)

Elastomeric traffic coatings are meant to stay flexible and waterproof while handling temperature changes and subtle movement on roof surfaces. The standard that specifies the performance and testing criteria for these coatings is ASTM C957. It lays out the requirements for adhesion to common roofing substrates, elongation and recovery after deformation, tear resistance, film thickness, and weathering durability. Following this standard ensures the coating will resist cracking, peeling, and loss of waterproofing under Florida’s sun, heat, and rain while remaining suitable for normal foot traffic during maintenance. Other standards cover different types of coatings or focus on guides or quality management, so they don’t provide the same specific performance criteria for elastomeric roof/traffic coatings.
