Pro Base, Torch-Applied

Specifically designed as the base ply of PMMA liquid-applied roofing and waterproofing systems, Pro Base series sheets are high-performance SBS-modified bitumen base plies for use with Siplast's Parapro and Paraflex Membrane Systems. Torch-applied to approved substrates, its unique top surface is factory-coated with a proprietary Syntan® acrylic coating, while the back surface is coated with a high-performance modified asphalt adhesive layer specifically formulated for torch applications. The adhesive layer is manufactured using a special process that embosses the surface with a grooved pattern to provide optimum burnoff of the plastic film and maximize application rates.

• Approved for a maximum 14 days of exposure prior to application of Parapro or Paraflex materials.
• Available with Siplast RoofTag RFID.
