GacoFlex SF2000 SeamSeal

GacoFlex SeamSeal, a silicone-based, solvent-free sealant combined with a reinforcing agent, adheres to seams, fasteners and other roof details in a single application. GacoFlex SeamSeal transforms a roof with seams, gaps, and overlaps into a seamless foundation ready for coating with GacoFlex Solvent-Free 100% Silicone Coating.
GacoFlex SF2000 SeamSeal is a silicone-based, solvent-free, single-component waterproof elastomeric moisture-curing sealant combined with a reinforcing agent.

SeamSeal is intended for application over cleaned and primed roofs as a joint and fastener treatment in place of fabric and/or elastomeric sheet tape. It may also be used to repair blisters in spray polyurethane foam up to 4” in diameter, as a tape-seal over cracked polyurethane foam insulation, and as filler for applications over existing “alligatored” smooth BUR. SeamSeal is UV stable and may be used to repair most clean and dry roofing surfaces. It can also serve as a substitute for caulk on a variety of substrates.

  • 100% silicone solvent-free sealant
  • 1 coat on smooth surfaces. 2 coats on granulated and rough surfaces.
  • Limitations: Not intended to be used to repair blisters in polyurethane foam larger than 4” in diameter.
  • Mixing: Mix before application to ensure uniform color and consistency.
  • Thinning: Product should not be thinned.
  • Primer: Existing silicone coatings should not be primed. On all other substrates, apply GacoFlex E5320 2-Part Epoxy Primer/Filler according to label directions.
  • Dry Time: Allow to dry a minimum of 4 hours at 55°F (13°C) or higher before coating with GacoFlex Solvent-Free Silicone Coating (product is moisture cure, low humidity will result in longer dry times); coat within 4 to 48 hours.
  • Clean Up: Clean application tools and equipment with 100% Pure Mineral Spirits Recirculate through lines and gun until residual coating is removed. DO NOT USE WATER OR RECLAIMED SOLVENTS.

    2-Part Epoxy Primer/ Filler

    GacoFlex E5320 is a two-component, water-based epoxy primer that is ideal for use on most roofing surfaces including metal roofs and flashings. This easy-to-apply primer bonds to properly prepared roofing surfaces and improves adhesion of GacoFlex silicone coatings and other top coats, especially on weathered surfaces that are difficult to get completely clean.

    On asphalt-based surfaces it may help prevent bleed-through, and when top coated will help prevent corrosion. When mixed with ordinary sand, it’s a masonry block filler.
