Usage Blueskin ® RF200 is a self-adhered rubberized waterproof roofing membrane underlayment. It is used as a secondary waterproofing layer on sloped roofs in both residential and commercial buildings, protect ing the building’s interior from damages caused by water infiltration as a result of ice dams or wind-driven rain. It is designed to be adhered directly to wood, gypsum decks or certain insulation panels prior to the application of finished roof coverings such as shingles, cedar shakes, and some architectural metal and tiles. Application Surface Prep: Blueskin ® RF200 is designed to be adhered directly to the structural deck or to certain insulation panels such as polyisocyanurate. Acceptable substrates include plywood, OSB, wood plank, wood composition, concrete, gypsum board sheathing, glass faced gypsum sheathing, metal and masonry. All substrates are to be free of dust, oil, dirt, debris, and moisture. All protrusions must be removed to provide a smooth surface. On re-roofing applications, remove old shingles, nails, and other loose materials. Priming is generally not required but is recommended over DensDeck ® , concrete or masonry substrates, or in cold weather. Prime with Blueskin ® Adhesive , Aquatac ™ Primer or Hi-Tac ™ Primer applied as per application and handling guidelines outlined in specific technical data sheets. Allow primer to dry to a tacky film. Primed surfaces not covered by membrane during the same working day must be re-primed. Note : Where furring strips or Z bars are installed immediately after installation of membrane, priming of substrate may be omitted. Optimum adhesion is achieved when ambient and surface temperatures are above 40 °F. For installation below 40 °F contact your Henry ® representative. Apply: Apply membrane parallel or perpendicular to slope. When applied perpendicular to slope, apply membrane beginning at low point and proceed in shingle fashion. Position sheet to achieve correct overlap and alignment. Release upper half of release film by peeling off at 90° angle, then peel back second half of lower release film. Overlap on to clear film on sides and at ends a minimum of 2.75” for all applications. Roof Edge Applications : When membrane is folded over the roof edge, it must be covered by flashing, gutter or metal edge. Apply membrane far enough up the roof deck to meet local codes and to prevent leaks caused by ice dam formations. Ridge and Valley Applications : Roll out and align manageable lengths of membrane. Slowly peel first half of release film. Press firmly in place beginning at center of ridge or valley. Repeat with second half of release film. Overlap at ends and sides a minimum of 3”. Apply in shingle fashion on valleys. Lap End Seals: Alternatively, seal end laps with Polybitume ® 570-05 Polymer Modified Sealing Compound or 925 BES Sealant. Limitations Not resistant to oils and solvents. Not designed for permanent exposure. Apply finish-covering materials as soon as practical following membrane application. If temperatures below 40 °F and/or high winds are expected prior to application of finish covering, secure membrane in place with mechanical fasteners to prevent delamination. Protect membrane from excessive traffic during application and until final roof covering is in place. Provide adequate insulation and ventilation in roofing systems or attic in cold climate areas. Thin films of dust, water, frost, or ice will affect the skid resistance of this product. Do not use in contact with flexible PVC (Poly Vinyl Chloride) membranes. New dimensional lumber decks may contain knots with resin levels that can attack and severely soften the bitumen compound causing flow. Henry will not be responsible for these areas. Packaging 3 feet wide X 65 linear feet = 1.95 SQ. roll. 30 shrink-wrapped rolls per pallet. Storage Store rolls on end in original pallets or elevated platform. Protect from weather or store in a dry enclosed area not subject to heat over 120 °F. Do not double stack pallets.
