GacoFlex Seamseal 100% Silicone SF2000
GacoFlex SF2000 SeamSeal


 
Gaco Flex Seamseal Solvent Free 100% Silicone Sealant


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.


If you're thinking about replacing your aging roof, think again. Renew your weathered roof with GacoFlex. It can be applied to virtually any surface, including flat roofs, to create a seamless membrane that seals and protects against the elements.
