SuperiorShield Rollershield-RS is a high quality 100% acrylic flexible fluid applied air and water barrier that is easily applied with a roller or spray equipment but also can be troweled or brushed into place. Rollershield-RS forms a continuous air and water barrier that protects approved substrates from incidental water damage.

Packaging/Shelf Life/Storage
Packaging: 5 gallon (19L) pail
Product Color: Naranja Durazno
Shelf Life: 2 years
Storage: Protect from extreme heat (90°F (32°C), freezing and direct sunlight.

Application Temperature: 40°-110°F (5°-43°C)
Dry to Touch: 1 hour @ room temperature
Recoat Time: 2 hours @ room temperature
Drying Time: 12 hours @ room temperature, working and drying time will vary with temperature and humidity.

Air and substrate temperature for application of Rollershield-RS must be 40ºF (5°C) or higher and must remain 40ºF (5°C) or higher for a minimum of 24 hours. Provide temporary protection to protect the wall system from damage until permanent flashings, caps and sealants are installed. Store materials within prescribed temperature limits and out of direct sunlight.
Working and drying times are based upon normal room temperature conditions and will vary with temperature and humidity.

The substrate must be approved by Master Wall Inc.®, clean, dry, structurally sound, and free of efflorescence, oil, grease, form release agents and curing compounds or anything that would affect bond. Painted surfaces are not acceptable and must be removed or bond test performed.
Substrates must be flat and free of fins or planar irregularities greater than 1/4” in 10’-0” (6.35 mm in 3.05 m).

Concrete – Must have cured a minimum of 28 days prior to the application of Rollershield-RS. If form release agents or curing compounds exist on the surface, they must be removed with a solution of muriatic acid or similar
product (with appropriate precautions). Remove any residual acid by flushing with water.
Brick/Masonry – If joints are not struck flush, multiple coats may be required. Porous CMU may require additional coats.
Sheathing Applications – Sheathing gaps must be less than 1/4” (6.4 mm).
See Technical Bulletin #189 for larger gap suggestions. Gap wood-based sheathing per manufacturers recommendations, typically 1/8” (3.2 mm) minimum.
Mixing – Thoroughly stir Rollershield-RS into a homogenous consistency.
Do not add water, over mix, or add accelerators or retarders to the product.
Application – Rollershield-RS is applied by first treating the joints and fastener locations where sheathing is used, then coating the entire surface using brush, roller, trowel, or airless spray equipment techniques. When using a foam roller, a maximum ¾” (19 mm) nap is recommended. Apply in an even, continuous coat, maintaining a wet edge of approximately 15 mils thickness. Oriented Strand Board and other porous substrates will require two (2) coats of Rollershield-RS. For moisture protection, apply Rollershield-RS as a continuous barrier of 10 mils dry thickness with no breaks or skips, although some areas will appear lighter than others due to the application process. The application need not look like a painted surface.
Joint Treatment—Apply a thin layer of Rollershield-RS to the joints and embed SuperiorShield Flashing Tape into the wet mixture and trowel smooth. Alternatively place and center SuperiorShield Mesh over all joints, corners, and gaps in the substrate. Immediately apply Rollershield-RS over the mesh and allow to dry.
Rollershield-RS may be flashed into window, door and other openings using the same techniques for sheathing applications. Any remaining gaps should be filled with additional Rollershield-RS, TG (Trowel Grade) or SuperiorFlash.
Wall Treatment—Apply Rollershield-RS to the wall surface using the foam roller, trowel or by spray applying and backrolling to a uniform thickness of 15 mils wet, 10 mils dry with no pinholes or voids.

Not for use as an exterior finish, note exposure limitations on front page.
When adhering Rollershield Drainage CIFS® to the surface assure it is clean, dry, and free of surface contamination. Remove any dirt or surface contamination before adhesive attachment.
Allowable in-service temperature range: -40° to 180°F (-40° to 82°C).
Fire-retardant or pressure treated plywood must be dry with surface free of salts or other chemicals migrating from within the wood. Test adhesion to be sure of desired results.
Use a slip sheet, typically one layer of building paper between Rollershield-RS and stucco or adhered masonry veneer over metal lath.

Rollershield-RS is compatible with GRACO and Titan airless spray equipment with the following specifications:
• Minimum 1 gallon per minute output.
• Minimum hose width of 3/8 inch.
• Minimum tip size of 0.027–0.031.
Minimum pressure requirement to spray of 2,000 psi at the gun with an airless sprayer rated no lower than 3,300 psi. Remove all filters in sprayer and gun before application.
Hopper Gun: 3/16”-1/4” (6-6.5 mm) orifice, 23-25 psi.

Tools and equipment can be cleaned with soapy water when Rollershield- RS is wet.

Hazard: This chemical is not considered hazardous according to the OSHA Hazard Communication Standard 2012 (29 CFR 1910.1200).
