ROOF MATE Step-By-Step Over HYPALON® ROOFING STEP 1 – Preparation Remove all loose gravel, dirt and debris to smooth the surface. Any unsound areas in the roof deck, insulation or flashing must be repaired or replaced. Remove gravel from ballasted Hypalon single-ply systems & spot ballast with sand bags to avoid excessive fluttering of the membrane. Ensure that the roof deck has positive slope to drain and that the moisture content of the existing substrate, insulation and deck does not exceed 15%. <BACK EXITMAIN MENUNEXT>EXIT

ROOF MATE Step-By-Step Over HYPALON® ROOFING STEP 2 – Cleaning Roof surfaces must be clean, dry, structurally sound, stable, well secured, and free of excessive ponding water. All Hypalon surfaces, whether new or existing, shall be cleaned using United Cleaning Concentrate (UCC) or comparable biodegradable cleaner. Heavy deposits of dirt or contamination may require agitation with a stiff-bristle broom or similar mechanical scrubber. If existing membrane exhibits significant deterioration (large areas of exposed reinforcement scrim, severe chalking and/or checking), utilize a low pressure rinse with extra attention given to "birdbaths" and other low areas. <BACK EXITMAIN MENUNEXT>EXIT

ROOF MATE Step-By-Step Over HYPALON® ROOFING STEP 3 – Details Tighten or re-secure all terminations and caulk termination bars and reglet counter-flashings with ROOF MATE Butter Grade. On all mechanically fastened single-ply systems, remove and reinstall any fasteners that are backed out or "tented", no more than 6” (15 cm) from its original location. Repair all loose, torn or open seams in the membrane, as well as any tears, breaks and holes using ROOF MATE Mesh embedded into either ROOF MATE Butter Grade or ROOF MATE Basecoat. Apply ROOF MATE Basecoat or Butter Grade liberally around the area to be reinforced. While the material is still wet, embed a strip of ROOF MATE Mesh, centered over the detail, applying additional material to totally encapsulate the reinforcement fabric. Reinforce around drains, scuppers, flashings and protrusions by applying a heavy coat of ROOF MATE Butter Grade, or with ROOF MATE Mesh embedded into ROOF MATE Basecoat or Butter Grade as described above. <BACK EXITMAIN MENUNEXT>EXIT

ROOF MATE Step-By-Step Over HYPALON® ROOFING STEP 4 – Reinforcement Reinforce roofs exhibiting a high degree of surface degradation, split seams, etc., by embedding 40” (102 cm) wide rolls of ROOF MATE Fabric into ROOF MATE Basecoat or Unibase over the entire surface. Sandwich the fabric between two coats of ROOF MATE Basecoat, each applied at the rate of 1 to 1½ gallons per 100 sq. ft. (.4 to.6 l/m²). If using Unibase, roll out a 4’ to 10’ (1.2 to 2.5 m) length of fabric and either spray apply or pour Unibase evenly over the top side at the rate of approximately 2 gallons per 100 sq. ft. (.8 l/m²). Work the coating evenly throughout the fabric using a broom or roller so that it is totally encapsulated, eliminating any air pockets, wrinkles or gaps, and allowing the fabric to conform to the surface contours. Overlap consecutive passes of ROOF MATE Fabric a minimum of 2” (5 cm) on each side, taking care to ensure all edges are well secured. At drip edges, refasten all metal flanges and reinforce the area with ROOF MATE Butter Grade, or ROOF MATE Mesh embedded into a strip-coat of ROOF MATE Basecoat or Butter Grade. <BACK EXITMAIN MENUNEXT>EXIT

ROOF MATE Step-By-Step Over HYPALON® ROOFING STEP 5 – Coating Application Apply 1 to 4 separate coats of ROOF MATE, using airless spray or roller, at the total rate of 1.0 to 5.5 gallons per 100 sq. ft. (.4 to 2.2 l/m²), depending on full fabric application, desired warranty and/or specification requirements. Create a self-terminating flashing by extending the topcoat a minimum of 3” (7.5 cm) above all protrusions, parapet walls, etc. <BACK EXITMAIN MENUNEXT>EXIT

ROOF MATE Step-By-Step Over HYPALON® ROOFING *Rhino Top is a tough acrylic coating that is available in both smooth and textured formulations. It is ideally suited for horizontal surfaces that receive regular foot traffic. STEP 6 – Options Apply walk pads, ceramic roofing granules or Rhino Top as required to demarcate walkways and service areas, and/or provide non-skid characteristics. To enhance dirt release characteristics in problem areas, apply a coat of Acrysheen, which imparts a slick, semi- gloss finish that aids in maintaining a clean surface. <BACK EXITMAIN MENUNEXT>EXIT
