Description

Vulkem® 801 is a heavy-duty, single-component, liquid-applied aluminized polyurethane coating. Designed with high tensile strength, tear resistance, and elongation, Vulkem 801 forms a robust, weather-resistant, elastomeric membrane. It cures into a waterproof, UV-stable coating suitable for a variety of demanding horizontal and vertical waterproofing applications.

Features & Benefits

  • Heavy-Duty Protection: High tensile and tear strength with 375% elongation for robust, flexible coverage.
  • Weather & UV Resistant: Performs exceptionally in exposed conditions and resists long-term degradation.
  • Waterproof: Seamless membrane blocks moisture intrusion in critical areas.
  • Versatile Application: Effective on both horizontal and vertical surfaces such as roofs, parapets, and gutters.
  • Ponding Water Resistant: Durable even in areas of standing water, ideal for gutters and drainage systems.
  • Tank Compatible: May be used in cooling water tanks (consult Tremco Technical Service first).
  • Easy Installation: Roller or spray application with 96.83% solids for efficient, even coverage.
  • Recoatable & Repairable: Can be reapplied or repaired as necessary with appropriate prep.
