Ply Sheet HA 87

Hot applied SBS modified bitumen fiberglass reinforced ply sheet

Ply Sheet HA 87 is a 87 mil (2.2 mm) thick hot applied SBS modified bitumen fiberglass reinforced ply sheet for use within Sarnafil® hybrid roofing systems. Ply Sheet HA 87 can also be used as a vapor retarder in Sarnafil® and Sikaplan® roofing systems.  It can be left exposed for up to six (6) months.

  • Superior tensile strength
  • Weathering surface allows for exposure for up to six (6) months
  • Fiberglass reinforcement provides dimensional stability
  • Fine mineral aggregate (sand) topside accepts approved urethane adhesives for membrane attachment

Application

Application steps

SUBSTRATE PREPARATION

All surfaces must be clean, sound, dry, and free of loose materials or contaminants such as water, frost, ice, oil and grease that would interfere with proper adhesion and compromise the performance of the product.

 

In accordance with the ICRI Technical Guideline No. 310.2R-2013, newly poured concrete surfaces must be finished by forming, wood float, steel or power trowel, or broom finished to meet the equivalency of a CSP type surface between a rating of 2 – 5.

 

Application to structural concrete surfaces and DensDeck Prime require priming with Vapor Retarder Primer TA or Vapor Retarder Primer BE.  See Vapor Retarder Primer TA or Vapor Retarder Primer BE product data sheet for additional information.

APPLICATION

Prior to installation, unroll Ply Sheet HA 87 onto the roof surface and allow it to relax. Place Ply Sheet HA 87 in desired position and back roll the product. Apply a full mopping of Type III or Type IV asphalt in accordance with industry standards at a minimum rate of 25 lbs per 100 square feet (1.2 kg/m²). Install Ply Sheet HA 87 so that there are no significant and avoidable air spaces between the ply sheet and the substrate.

    

Ply Sheet HA 87 can be installed with Sika’s cold applied vapor retarder adhesives. See Sika’s vapor retarder adhesive product data sheets for additional information.
