CPR™ Seam Sealer

  • Durable
  • Versatile
  • Stable & Resilient

CPR Seam Sealer is a synthetic liquid rubber, brush grade (BG) or trowel grade (TG) mastic specifically designed for application to metal roofs, walls, and problem areas such as gutters, expansion joints, etc. CPR Seam Sealer can be easily applied over sloped, contoured surfaces and will provide long-lasting protection. It cures to a monolithic rubbery membrane with high tensile strength and the ability to elongate and recover. For areas that experience high movement, use either CPR Seam Sealer with Grip Polyester ™ Soft for long-lasting protection.
