- WrapShield SA Self-Adhered building layout should be planned prior to application to minimize waste, this process will assist locating penetrations that will need to be correctly detailed to ensure a weather and air tight installation.
- WrapShield SA Self-Adhered can be installed in a vertical or horizontal direction.
- Always install in a “weatherboard or shingle fashion” with the lower courses lapped under the upper courses.
- All penetrations including windows and doors must be installed in proper sequence to ensure a “weatherboard or shingle fashion” end result.
- All overlaps must be a minimum of 3” (8 cm) on horizontal and vertical seams.
- Inside and outside vertical corners should be minimum 6” (15 cm) of overlap.
- Vertical seams should be staggered from floor to floor, or separated by a WrapShield SA Self-Adhered horizontally applied strip.
- Use a roller (Figure 1) to ensure adhesion at seams (overlaps).
- Sustains six (6) months (180) days UV and climate exposure prior to cladding installation.
- The substrate condition is crucial to the adhesion performance of any adhesive membrane.
- Substrates must be clean and free of any contaminants.
- Substrate surface must be dry to the touch with the ambient temperature above 20°F (-6°C).
- WrapShield SA Self-Adhered can be applied to a wide variety of sheathing substrates:
- DensGlass Gold
- Most rigid insulation
- Pre-painted steel
- Precast concrete
- Concrete block
- Aluminum (painted or mill finish)
- Cast-in-place concrete
- Galvanized metal
- Rigid vinyl
- Anodized aluminum
- OSB is not an approved substrate for WrapShield SA Self-Adhered, use WrapShield IT Integrated Tape. If you have questions regarding substrates contact VaproShield Technical Team
- PRIMER IS NOT REQUIRED
During the installation process, WrapShield SA Self-Adhered must be protected at the leading edge to ensure liquid water does not travel behind the membrane.
Adhesive Curing Time
- Membrane is easily repositioned for up to 30 minutes after initial installation
- Normal curing time is approx. 6 hours.
- Full adhesion will vary depending on job site weather conditions.
Floor Line Movement
- Buildings are designed to accommodate thermal and seismic movement.
- WrapShield SA Self-Adhered must be installed to allow this movement throughout the life of the structure.
- To accommodate floor-line movement: Limit coverage area to a single floor and shingle subsequent layers over the top leading edge.
WrapShield SA Self-Adhered is Non-Directional
- Install pieces vertically or horizontally.
- Ensure “weatherboard manner” by installing pieces over the top of the pieces below.
- Pieces are easily cut to size.
- Window and door penetrations can be detailed pre or post installation of the field membrane.
- Always ensure weatherboard result is achieved.
Original Packaging Functions as Dispenser
- Keep WrapShield SA Self-Adhered in original packaging
- Carefully lift one end of the product out of the box and slide the plastic wrap towards the opposite end.
- Insert roll into end.
- Replace the roll in the box/dispenser and carefully remove the tape in the middle of the roll.
- Keep plastic roll cover to protect partial rolls during installation.
- Pre-cut material into individual manageable lengths by pulling material off the main roll to desired length.
- Cut material square to the factory edges.
- Re-roll material same direction it came off the roll, with the release film outward.
- Cut material to desired length with extended blade razor knife.
Tip: pre-cut material for desired lengths for rough openings. Label as needed on release film with marker.
Single Worker vs. Two Worker Installation
- Using the material at its full width, 59” (1.5 m), vertical installation can be easily accomplished by a single worker.
- Horizontal installation of the full width material is best accomplished by two workers.
- Partial width rolls are easily installed by a single worker.
- View details of installation sequence and view videos on our website for further clarification.
Vertical and Horizontal Installation
Horizontal installation of the WrapShield SA Self-Adhered material is similar to the vertical installation method. The material can be applied either left to right, or right to left.
Best Practice Installation Sequence
- Snap a level chalk line for guidance
- Pre-cut material to desired length
- Roll material with release film facing OUTWARD
- Starting at a corner of the roll, peel back approx. 6” (15 cm) of release film
- Cut the release film with razor knife and tear the cut portion of the release film exposing approx. 6” (15 cm) of glued surface
- Using hand pressure, lightly apply the exposed glue surface to the substrate
- Starting in the middle, use your hands to smooth out air bubbles, releasing the air to each side
- APPLIES ONLY TO VERTICAL INSTALLATION - Allow the rolled up material to drop down the wall, with the remainder of the release film still attached, checking for proper alignment
- Reposition as needed - the material is very forgiving allowing for easy re-alignment
- When aligned, apply heavy hand pressure across the entire adhered section
- Roll up the material with release film facing OUTWARD
- Slowly pull the release film down the wall, allowing the rolled up material to unfurl
- Lightly smooth out air bubbles with wallpaper trowel
- Continue until all the release film has been removed
- Pull back and reposition material (if necessary) as it unfurls
- Apply heavy pressure to the entire substrate to ensure full adhesion
- Use a roller to ensure adhesion at seams (overlaps). Figure 1
- Proceed to next step, ensuring a 3” (8 cm) minimum overlap to the adjoining material, always in a weatherboard manner
Installation Best Practices
- Avoid scoring the membrane at locations where the material overlaps onto the adjacent piece.
- Allow the top layer of material to span across the underlying layer without attempting to force the material into a 90° bend.
- Avoid stretching the material during installation at inside and outside corners.
- A full 6” (15 cm) overlap in either direction is recommended vertically at inside and outside corners.
- Store vertically
- Keep dry
- Between 40° F and 120° F (4ºC - 49ºC)
