Due to solvent flash off, condensation may form on freshly applied primer when the ambient temperature is near the dew point. If condensation develops, possible surface contamination may occur and the application of primer must be discontinued. Allow the surface to dry and re-apply.
Extreme care must be exercised when working on ladders, roofs, or at elevations above ground. If used as an emergency repair to a roofing system, contact the roofing system manufacturer for compatibility and to ensure compliance with terms and limitations of the warranty.

Cut the ClassicBond EPDM rubber roofing membrane at 45° angle to allow the membrane to run around the corner and create both upstands. Bond in place with ClassicBond Bonding Contact Adhesive. Cut a section of 225mm Uncured Flashing Tape (or use an external corner patch) to a min. 75mm onto deck and 50mm past angled cut in membrane.
Apply ClassicBond Primer to the marked area to be flashed and allow to dry. The area must be clean and dry before application of primer, apply primer to membrane and to upstand substrate. ClassicBond Primer must be allowed to dry before application of tapes.
Start installing the tape from the top point. Work the tape down upstands first and into the bottom angle change applying pressure with a seam roller as you reach the bottom
Work the tape onto the deck around the corner and smooth out and roll the entire flashing with seam roller.
