OUTSIDE CORNER FINISH DETAIL

  1. Prior to installing any flashings, using the RUBBERALL Scratch Pad, apply Seam Tape Primer to all areas to be flashed. Cut Uncured Flashing Patch six inches (6") wide by eight inches (8") long from a twelve inch (12") by twelve inch (12") Uncured Flashing Patch. Cut the corners round. After the Primer has dried, fold one end of the flashing two inches (2") from the end. Place the membrane against the vertical surface so that half the flashing is on either side of the corner. Fold the flashing around the corner and adhere to the vertical surface. The flashing should extend two inches (2") onto the roof deck, and six inches (6") up the vertical.

  1. Adhere the flashing at each inside corner and stretch the middle of the flashing towards each corner as the flashing is mated to the field membrane.

    IMPORTANT:     The outside and inside corners should NOT BE STRETCHED! All stretching should be done in the middle of the bottom part of the flashing.

  2. The second layer of Uncured Flashing Patch should be installed following the same flashing procedures as the first, but using a 12"x12" Uncured Flashing Patch (see Figure 13 c). This patch should extend onto the roof a minimum of four inches (4") and up the vertical a minimum of eight inches (8").

    For example:
    If the first ply of flashing measures six inches (6") wide by eight inches (8") long, the second ply should measure ten inches (10") wide by twelve inches (12") long.

  3. If it is necessary to add flashing membrane to attain a taller flashing detail, cut field membrane the desired dimensions and adhere the new membrane over the previously installed mem brane and flashing details.

IMPORTANT: ALWAYS EXTEND THE NEW FLASHINGS ABOVE ANY EXISTING MEMBRANES OR FLASHING MATERIALS.
