1. Pre-cut Liquid Flashing Fleece to fit around the penetration. Vertical flashing pieces must extend 2" (51 mm) from the base onto the horizontal and horizontal flashing pieces must extend 4" (10.2 cm) out from the base of any penetration. Flashing height should be a minimum of 8" (20.3 cm). Horizontal flashing fleece pieces must extend a minimum of 4" (10.2 cm) beyond the leading edge of the penetration, or a minimum of 2" (51 mm) beyond the edge of the fastening plate. Add 2" (51 mm) for the overlap with adjoining pieces.
2. Once the edges of the fleece are determined, mark a line on the membrane ½" (13 mm) beyond the edge of the fleece and apply painter’s tape. This will accommodate the ½" (13 mm) of non-reinforced Liquid Flashing needed to terminate to the membrane.
3. With the tape in place, clean the membrane within the area using Sika's Seam Cleaner, acetone, or methyl ethyl ketone (MEK) including the plates and the penetration.
4. Mix and apply catalyzed Liquid Flashing SW or Liquid Flashing WW. Refer to the Liquid Flashing SW and Liquid Flashing WW product data sheets for mixing instructions and application procedures.
5. Using a small ½" (13 mm) nap roller with rounded edges or 2" (51 mm) disposable paint brush apply 55 mils (1.4 mm) of catalyzed Liquid Flashing onto the penetration up to the finished flashing height and 2" (51 mm) onto the roof membrane.
6. Embed the pre-cut vertical Liquid Flashing Fleece into the wet Liquid Flashing. Use the roller or brush to eliminate wrinkles and air bubbles while completely saturating the Liquid Flashing Fleece. Apply additional catalyzed Liquid Flashing at the 2" (51 mm) overlap between the vertical Liquid Flashing Fleece layers.
7. Apply 55 mils (1.4 mm) of catalyzed Liquid Flashing onto the roof membrane extending slightly onto the painter's tape. Also coat the 2" (51 mm) fingers from the vertical Liquid Flashing Fleece.
8. Embed the pre-cut horizontal Liquid Flashing Fleece into the wet Liquid Flashing. Use the roller or brush to eliminate wrinkles and air bubbles while completely saturating the Liquid Flashing Fleece. Apply additional catalyzed Liquid Flashing at the 2" (51 mm) overlap between the horizontal Liquid Flashing Fleece layers.
9. Apply 25 mils (0.6 mm) of catalyzed Liquid Flashing over the entire exposed vertical and horizontal flashing fleece terminating at the finished flashing height on the vertical and onto the painter's tape on the roof. Make sure the fleece is fully saturated without any dry spots.
10. Remove the painter's tape immediately after applying the final 25 mils (0.6 mm) of catalyzed Liquid Flashing.
