  2. All surfaces must be clean, dry, smooth, and free of sharp edges, fins, loose or foreign materials, oil, grease or residue.

3.02 INSTALLTION OF AIR BARRIER SYSTEM

  1. Self-Adhered Air Barrier Membrane:

    1. Firestone Enverge Air and Vapor Barrier SA Membrane must be installed in accordance with current Firestone Building Products specifications and details.

    2. Application temperature for 25 mil membrane should be min. 50 ºF (10 °C). Application temperature for 40 mil membrane should be min. 14 ºF (-10 °C).

    3. Prime substrate to receive air barrier membrane as required per manufacturers written instructions.

    4. The use of a primer is recommended in most applications. Apply a coat of Enverge SB Primer (Solvent Based) – W56-358-7093 or Enverge WB Primer (Water Based) – W56-358-7094 or Enverge LVOC Primer prior to installing the membrane.

    5. Primer is required for surfaces such as OSB, wood, concrete, gypsum or fiberglass structural panels Allow primer to dry. When dry, the primer will feel tacky when using a dry finger test.

    6. Polyurethane foam can be sprayed directly onto Enverge membrane. However, the membrane should be mechanically fastened to the substrate using a termination bar to junctions, window or door frames, endings, and on the perimeter of the building.

    7. Firestone Enverge Air and Vapor Barrier SA Membrane may be left exposed up to 90 days.

    8. Begin installation at the base of the wall placing top edge of membrane immediately below any masonry reinforcement or ties protruding from substrate. Overlap seams 3 inches.

    9. When properly positioned, place against surface by pressing firmly into place. Roll membrane with extension-handled countertop roller immediately after placement.

  2. Through-Wall Flashing Membrane:

    1. Firestone Enverge Thru-Wall Flashing SA Membrane must be installed in accordance with current Firestone Building Products specifications and details.

      1. Surfaces must be clean, dry, smooth, and free of sharp edges, fins, loose or foreign materials, oil, grease or residue.

      2. Prime surfaces and allow to dry, press membrane firmly into place, overlap minimum 2 inches at all end and side laps. Promptly roll all laps and membrane to ensure the seal.

      3. The use of a primer is recommended. Apply a coat of Enverge SB Primer (Solvent Based) – W56-358-7093 or Enverge WB Primer (Water Based) – W56-358-7094 or Enverge LVOC Primer prior to installing the flashing.

      4. Application temperature should be min. 14 ºF (-10 °C).

      5. Primer is required for surfaces such as OSB, wood, concrete, gypsum or fiberglass structural panels. Allow primer to dry. When dry, the primer will feel tacky when using a dry finger test.

      6. Polyurethane foam can be sprayed directly onto Enverge flashing. However, the flashing should be mechanically fastened to the substrate using a termination bar to junctions, window or door frames, endings, and on the perimeter of the building.

      7. Enverge Thru-wall Flashing SA Membrane may be left exposed up to 90 days.

      8. Hold flashing back 1/4 inch from face of wall surface with 3 inch overlap at seams.

  1. Primers

    1. Use Enverge SB Primer to prime and prepare exterior concrete, metal, wood and plywood surfaces to strengthen the adherence of self-adhesive Enverge Air and Vapor Barrier SA Membrane and Flashing.

      1. Application temperature should be min. 14 ºF (-10 °C).

      2. Mix before and during application.

      3. Apply Enverge SB Primer to clean, dry surfaces using a brush, roller or Airless sprayer.

      4. Allow primer to dry before installing the membrane or flashing. Drying time varies from 15 to 60 minutes, depending on ambient temperature and amount applied. It’s dry when sticky to the touch but not messy.

      5. For best results, install the membrane, or waterproofing flashing as soon as the primer is dry.

      6. Clean tools with petroleum solvents (petroleum spirits, Xylene, etc.).

    2. Use Enverge WB Primer to prime and prepare interior or exterior concrete, metal, wood, polystyrene surfaces, and gypsum plasterboard to strengthen the adherence of self adhesive Enverge Air and Vapor Barrier Membrane and Flashing. It is particularly recommended when the solvent based primer is not advised.

      1. Application temperature should be min. 41 ºF (5 °C).

      2. Membranes must be installed on the same day as the application of Enverge WB Primer.

      3. Mix before and during application.

      4. Apply Enverge WB Primer to clean, dry surfaces using a brush, roller or an airless sprayer. Spray tip size: between 20 and 25 mil and pressure: 1300 psi continuous.

      5. Allow primer to dry before installing the membrane or flashing. Drying time varies from ½ to 3 hours, depending on ambient temperature and amount applied. It’s dry when sticky to the touch but not messy.

      6. For best results, install the membrane, or waterproofing flashing as soon as the primer is dry.

      7. Clean uncured material from tools with water. Cured material is best removed by solvents (Mineral spirits, Varsol, Xylene, etc.).

    3. Enverge LVOC Primer

3.03 FIELD QUALITY CONTROL
