All surfaces must be clean, smooth, sound, dry, and free of loose materials, debris or contaminants such as water, moisture, frost, ice, oil and grease that would interfere with proper adhesion and compromise the performance of the product.

  
In accordance with the ICRI Technical Guideline No. 310.2R-2013, newly poured concrete surfaces may be finished by forming, wood float, steel or power trowel, or broom finished to meet the equivalency of a CSP type surface between a rating of 2 – 5.

Vapor Retarder Primer SB, Vapor Retarder Primer VC or Vapor Retarder Primer WB is required on all substrates except for steel. Concrete surfaces must be dry before installation. Shake or stir primer before applying. Primers can be rolled, brushed or sprayed. Let the primer dry completely. Begin the installation at the low point of the roof. Chalk a line on the deck to align the sheet. Unroll, position, and align Vapor Retarder SA 106 with the release liner covered selvage edge on the up-slope side. After the sheet is placed in its final position, loosely reroll half of the sheet toward the center of the roll.

  
Carefully score the release liner across the width of the roll with a straight blade utility knife. Roll Vapor Retarder SA 106 into its final position as the release liner is being removed. Re-roll the remaining Vapor Retarder SA 106 and repeat the process.

  
On steel decks install a 6" x 42" (15.2 cm x 1.1 m) metal plate under the end lap to support the membrane between the steel flutes. Stagger the end laps by at least 12" (30.5 cm). Roll Vapor Retarder SA 106 with a 75 lb (34 kg) steel roller to ensure full contact with the substrate.

  
Align successive sheets with 3" (7.6 cm) side laps and 6" (15.2 cm) end laps. The seam area has a pre-applied primer/adhesive on one side for mating with the bottom of the next sheet. Remove the release liner from the seam area and mate the top sheet to the bottom. Roll the seam area to ensure full contact. Hot air weld the end laps. Hot air welded laps must show a minimum ½" (1.3 cm) bleed out. Stagger adjacent end laps a minimum of 12" (30.5 cm). Apply Sika’s Mastic to seal around penetrations. Use a trowel to mound Sika’s Mastic around the penetrations to seal the opening. Do not apply Sika’s Mastic where it may come into direct contact with the Sarnafil® or Sikaplan® membrane.
