SWEPCO Heavy Duty Polyform, a tough reinforcing fabric specially designed for renewal of gravel roofs. When this remarkably strong 100% polyester fabric is embedded between two coats of Heavy Duty or Flex Shield Roof Coating, an economical new waterproofing membrane with outstanding performance characteristics is the result. Superior strength, stretchability, and durability produce a roof which will outlast conventional approaches. It ‘conforms’ to rough gravel surfaces, helping to eliminate future blistering problems and also reducing the likelihood of punctures.
Application: by hand (use gloves) cut to size using a sharp blade or scissors.
Coverage: 110m rolls by 91cm wide.
