Duro-Shield™ Coatings and Materials

Duro-Shield™ Coatings Overview

With constant exposure to heat, cold, UV radiation, rain, snow, hail, high winds and possible mechanical damage, a roof can be the most vulnerable component of a building’s exterior. However, a roof’s long-term performance can be enhanced — and major roofing problems avoided — with correct design, quality materials, proper installation and workmanship, and comprehensive care.

Duro-Shield Roof Coatings and Materials – available in Duro-Shield 20, Duro-Shield 10 and Duro-Shield 5 - are 100% elastomeric acrylic, and are designed to seal and protect a variety of substrates. Their brilliant white finish reflects the sun’s rays, which can lower heat buildup and reduce energy costs.

When properly prepared and applied in accordance with Duro-Last®’s specifications, the Duro-Shield line of roof coatings can be used on the following roof substrates:

  • Single-ply membranes:
    • PVC (polyvinyl chloride)
    • EPDM (ethylene propylene diene monomer)
    • Hypalon CSPE (chlorosulfonated polyethylene)
    • TPO (thermoplastic polyolefin)
  • Metal
  • Mineral and granule-surface built up (BUR) and modified bitumen
  • Smooth-surfaced built up (BUR) and modified bitumen
  • Wood

Additional Duro-Shield Products

In addition to the Duro-Shield line of roof coatings, there are other supporting products in the coatings family:

  • Duro-Shield Primer: Formulated with a rust inhibiting compound, the application of this primer is required on all substrates before using any of the Duro-Shield coatings.
  • Duro-Shield Brush Grade Mastic: Heavy-bodied, flexible, elastomeric caulk and sealant for filling and patching cracks and voids in various substrates prior to application of Duro-Shield Primer and roof coatings.
  • Polyester Reinforcement Fabric: Used with Duro-Caulk® Advanced, this flexible polyester fabric creates strong, resilient bonds by reinforcing seams, flashings and penetrations.
