Lap Sealant is a low volatile organic compound sealant designed to be used with approved primers for seam edge treatment applications and as a sealant in other applications as indicated by current specifications and details.

Method of Application

  1. Surfaces to which Lap Sealant is applied must be clean, dry, and free from loose or foreign materials, oil, and grease.
  2. Wait to apply seam edge treatment a minimum of four (4) hours after the completion of a flashing seam, but no later than the end of the next day following the completion of the seam. If inclement weather is threatening, apply an approved primer to the edge of the flashing splice before leaving project.
  3. If the seam edge has been contaminated, clean the seam edge a minimum of 1″ (25.4 mm) on each side of the step-off with Splice Wash and allow to dry.
  4. Apply an approved primer along the entire seam edge, a minimum of 1″ (25.4 mm) on each side of the step-off, following Elevate Seam Edge Treatment application procedures and allow the primer to flash-off.
  5. Using the plastic nozzle applicator supplied by Elevate, apply a continuous bead of Lap Sealant approximately ⅜” x ¼” (9.5 mm x 6.3 mm) centered over the flashing seam edge. Be sure to keep the applicator centered over the lap step-off. Refer to current Elevate seam details.
