Description

Lanco® Siliconizer™ 1000 RC-1062 is a premium 100% silicone, high-solids, moisture-cure roof coating designed for long-lasting waterproofing and extreme weather resistance. Engineered for commercial and residential low-slope and flat roofs, this white reflective membrane offers exceptional UV protection, permanent ponding water resistance, and strong adhesion to a wide range of substrates. Ideal for hot, wet, tropical climates, Siliconizer™ 1000 cures to a seamless, flexible membrane that expands and contracts with the roof’s movement.

Features & Benefits

Recommended Applications

Siliconizer™ 1000 is ideal for protecting and restoring the following roof types:

  • Aged Asphalt Roofs (BUR, Modified Bitumen)
  • Single-Ply Roofs (EPDM, TPO, PVC, Hypalon®)
  • Spray Polyurethane Foam (SPF)
  • Metal Roofs
  • Concrete Roofs
  • Previously Coated Roofs
  • Mobile Homes, RVs, and Trailers

Not recommended for:

  • Shingle roofs
  • Cold storage applications without a vapor barrier
  • Direct application over fresh asphalt without primer
  • Continuous immersion or submerged conditions

Application Details

  • Surface Preparation:
    • Clean with non-filming detergent (TSP)
    • Remove all dirt, grease, moss, and debris
    • Treat algae/mold with a 1:1 bleach solution
    • Allow surface to dry fully before application
    • Remove rust on metal roofs with a wire brush
    • Perform adhesion test patch before full application
  • Mixing: Use a 3”+ paddle with a drill to mix thoroughly before and during use
  • Application Methods:
    • ½”–1” nap roller, brush, or commercial airless spray rig (3500 PSI, 3 GPM minimum)
  • Minimum Coverage:
    • Smooth surface: 1.5 gal per 100 sq. ft. (22 mils DFT)
    • Rough surface: Higher coverage required
  • Recoat Window: 2–6 hours between coats; must recoat within 48 hours
  • Clean-Up: Use mineral spirits or VM&P Naphtha before product cures
  • Precautions:
    • Do not apply if rain is expected within 15 minutes
    • Surface may be slippery when wet
    • Not for interior use or food-contact surfaces
    • Use protective equipment; vapors may cause irritation
