Ideal for applications requiring the coating to flow into small crevices and hard to reach areas, NovaFlex Seam Sealer is a semi-self-leveling liquid that cures to a rubber-like solid which will not crack or drop out of joints.

NovaFlex Seam Sealer is a non-corrosive, single-component silicone sealant that is ideal for applications that require the coating to flow into small crevices and hard to reach areas. It may also be used as a horizontal joint sealant and crack filler.

How to Buy
 
  • Details

    We recommend it for sealing rivets, gutters, corner joints, and screw heads. Please note: due to the flowable nature of Seam Sealer, it may not be suitable for use on vertical joints unless tooled immediately after application. Consider NovaFlex Void & Cavity Filler for vertical applications.

    Not recommended for joints continuously submerged under water, areas needing paint or stain, spaces confined from atmospheric moisture during cure, on surfaces that might bleed oils, plasticizers, or solvents, in structural glazing applications, or painted applications.

    Meets or exceeds the performance characteristics of AAMA 803.3, Type II.
