FAQ: Professional Terms on Waterproof Coating on Roof
1. What is the difference between high polymer waterproof membrane and traditional bituminous membrane?
High polymer (TPO, PVC, EPDM) membranes exhibit superior flexibility, UV/weather resistance, useful life (>20 years), and lower VOC emissions compared to traditional bituminous membranes.
2. Which standard governs the testing of waterproof coating on roof?
Key global standards include ASTM D6083 (liquid-applied elastomeric coatings), ISO 9001 (quality), ISO 14001, EN 13707, and FM/UL for fire and impact resistance.
3. How is coating thickness determined and why is it important?
Thickness (1.0–4.0 mm) is specified based on substrate, traffic, climate, and desired service life. CNC caliper/measuring equipment ensures uniformity per ANSI/ISO metrology standards.
4. What is elongation at break and why does it matter?
Elongation at break (%) measures a coating's ability to stretch without tearing. A higher value (over 400%) provides superior crack-bridging over moving joints and thermal-induced cracks.
5. Is waterproof membrane for roof suitable for green roof or rooftop solar?
Yes. Both liquid coatings and high polymer membranes are root-penetration resistant (FLL compliant), bear the load from solar racks/planters, and reflect heat to enhance solar PV efficiency.
6. What kind of maintenance is required post-installation?
Waterproof coatings require annual visual inspection, regular cleaning, and prompt repair of mechanical damage (if any) to maximize service lifespan.
7. How are chemical resistance and fire performance verified?
Via laboratory tests: ISO 2812 for chemicals (acid/alkali), EN 13501/UL790 for fire, and accelerated weathering using QUV/ISO 4892 standards.
