SikaFill®-370 Duralastic Fibers (Fiber-reinforced, acrylic, elastic liquid-applied waterproofing coating for flat roofs)

SikaFill®-370 Fibers is an elastic coating with a creamy consistency, based on styrene–acrylic copolymers in an aqueous emulsion with glass fibers. After curing, SikaFill®-370 Fibers forms a flexible, waterproof, and durable membrane using Duralastic technology.

  • As a liquid-applied waterproofing membrane for flat roofs with occasional pedestrian traffic and peripheral vertical surfaces
  • On substrates such as corrugated sheets, bituminous shingles, concrete, mortars, zinc, and steel

  • Fiber-reinforced
  • Capable of bridging cracks
  • Good adhesion to various substrates
  • High color stability / non-yellowing
  • Easy to apply
  • Not resistant to ponding water
  • Also applicable on vertical surfaces

Diluted with 10% water (as a primer): ~0.7–0.9 kg/m² per coat

On flat roofs: ~1.0 kg/m² per coat (2–3 coats)

On vertical surfaces: ~0.5 kg/m² per coat (2 coats)
