Joint Treatment-Apply a thin layer of Rollershield-RS to the joints and embed Rollershield Flashing Tape into the wet mixture and trowel smooth. The Rollershield-RS application need not look like a painted surface. For moisture protection, Rollershield-RS must be applied 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. Oriented Strand Board and other porous substrates require two (2) coats of Rollershield-RS. Apply Rollershield-RS in a n even, continuous coat, maintaining a wet edge of approximately 15 mils thickness. When using a foam roller, a maximum ВѕвЂќ (19 mm) nap is recommended.

Do not add water, over mix, or add accelerators or retarders to Rollershield-RS.ДЄpplication вЂ“ Rollershield-RS is applied by first treating the jointsВ andДЇastener locations where sheathing is used, then coating the entire surface using brush, roller, trowel or airless spray equipment techniques. Mixing вЂ“ Thoroughly stir Rollershield-RS into a homogenous consistД®ncy.

Gap wood-based sheathing per manufacturers recommendations, typically 1/8вЂќ (3.2 mm) minimum. For gaps larger than 1/4вЂќ (6.4 mm) WeatherStop Tape or Rollershield Flashing Tape may be used. Sheathing Applications вЂ“ Sheathing gaps must be less than 1/4вЂќ (6.4 mm). Contact Master Wall for more information. Remove any residual acid by flushing with water.Д«rick/Masonry вЂ“ If joints are not struck flush, multiple coats may be required. 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).

Substrates must be flat and free of fins or planar irregularities greater than 1/4вЂќ in 10вЂ™-0вЂќ (6.35 mm in 3.05m).Д¬oncrete вЂ“ Must have cured a minimum of 28 days prior to the application of Rollershield-RS. Painted surfaces are not acceptable and must be removed. Preparation вЂ“ 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. Working and drying times are based upon normal room temperature conditions and will vary with temperature and humidity. Store materials within prescribed temperature limits and out of direct sunlight. Provide temporary protection to protect the wall system from damage until permanent flashings, caps and sealants are installed. Job Conditions вЂ“ Air and substrate temperature for application of Rollershield-RS must be 40вЏ (5вЊ) or higher and must remain 40вЏ (5вЊ) or higher for a minimum of 24 hours. m 2 300 Pa), ASTM E2485, AATCC 127, ICC ES (AC 212), NFPA 285, ASTM E1354, IBC Section 1403.5, Exception 2 Requirements Peak Heat Release Rate = 32 kWm2, Total Heat Release Rate = 3.6 MJ/m2, Effective Heat of Combustion= 2.5 MJ/kgДry to Touch: 1 hour room temperature, Recoat Time: 2 hours room temperature,Дrying Time: 12 hours room temperature at room temperature, working and drying time will vary with temperature and humidity
