Dicor 501LST-1 HAPS-Free Self-Leveling Lap Sealant for Horizontal Surfaces

Designed for RV roofs and other horizontal surfaces, this self-leveling lap sealant from Dicor delivers a clean, watertight seal along edges, vents, vent pipes, and screw heads. The tan shade helps it blend with many roof colors, and the 10.3 oz tube is compact enough for maintenance, quick repairs, or appliance-related sealing tasks on the go.

Product highlights

  • Self-leveling on horizontal surfaces creates a smooth, professional seal with minimal tool marks.
  • HAPS-free formulation reduces exposure during application while maintaining durability.
  • Tan color blends with most roof lines and prevents staining on surrounding materials.
  • Broad compatibility with EPDM, TPO and PVC membranes and strong adhesion to aluminum, wood, vinyl, and concrete.
  • Sun-ray stabilized to resist discoloration and wear over time, helping seals stay intact.

Ideal uses

Perfect for sealing RV roof edges, air vents, vent pipes, screw heads, and other penetrations on horizontal roofs. It supports routine maintenance, quick repairs, and appliance-related sealing tasks where a flexible, long-lasting seal is beneficial.

  • RV ROOFING USE: Self-leveling for even coverage on horizontal surfaces and a clean edge around details.
  • COMPATIBILITY AND ADHESION: Works with EPDM, TPO, and PVC membranes; bonds to metal, masonry, wood, vinyl, fiberglass, and concrete.
  • FLEXIBLE SEAL: Continuously seals while remaining pliable to accommodate movement and thermal cycling.
  • APPEARANCE AND UV RESISTANCE: Tan shade resists sun exposure and minimizes cosmetic changes on the roof surface.

Usage notes

For best results, follow the manufacturer instructions for surface preparation, tool usage, and cure times. The HAPS-free formulation is designed to minimize exposure while delivering a secure seal. Always allow the product to cure as directed before exposing to traffic or further weathering.
