GacoFlex SF2000 SeamSeal

GacoFlex SF2000 SeamSeal is a silicone-based, solvent-free, single-component waterproof elastomeric moisture-curing sealant combined with a reinforcing agent.

GacoFlex SF2000 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.

Adhesion is excellent to polyurethane foam. A primer may be required for adhesion to built-up roofing, modified bitumen capsheet, single ply roofing (EPDM, TPO, PVC and Hypalon), masonry, concrete, and wood. A primer must be used on all ferrous metals to prevent corrosion. Contact the Technical Department for specific recommendations.

Coverage: Apply SeamSeal on all metal seams, joints, fasteners and penetrations at 75 to 100 linear feet of seams per gallon or 450 fasteners per gallon.

Note: Application rate is job-specific. Additional material may be required due to surface profile, losses due to overspray and wind, and residual coating left in the container.
