Sarnafil® G 459-60

Sarnafil® G 459-60

G 459 is a PVC thermoplastic membrane that may be used in contact with asphalt or other contaminated surfaces or as a grid strip in waterproofing applications

G 459-60 can be adhered directly to asphalt or other contaminated surfaces. It is formulated for direct exposure to the weather, is heat-weldable and produced with an integral fiber glass mat reinforcement for dimensional stability. G 459-60 is used as a flashing membrane within Sarnafil® and Sikaplan® roofing and waterproofing systems. G 459-60 is also used in conjunction with Sikaflex-11 FC or Sarnafiller adhesives to construct sub-membrane water stops within the Sarnafil grid waterproofing system.

  • Back side resistant to asphalt
  • Glass reinforced for dimensional stability and durability
  • Lacquer coated top surface to reduce dirt pick up
  • Available in full width or pre-cut rolls

Product Details

Product Information

Chemical Base

High-quality product containing PVC resin, pigments, stabilizers, ultraviolet absorbers, and a fiberglass carrier sheet. The standard color is white on tan. The tan side of the membrane must be the side exposed to the contamination.

Reinforcing Material

Fiberglass

Shelf Life

N/A

Storage Conditions

Store rolls on pallets and fully protected from the weather with clean canvas tarpaulins. Unvented polyethylene tarpaulins are not accepted due to the accumulation of moisture beneath the tarpaulin in certain weather conditions that may affect the ease of membrane weldability.

APPLICATION

Flashing Membrane:

G 459 is installed on walls, curbs and other penetrations using Sika adhesives. The flashing can be installed horizontally or vertically depending on the specific detail. The seams are heat welded together by trained operators using hot-air welding equipment.


Grid Strip Membrane:

G 459 is installed by an authorized Sika Sarnafil Waterproofing Applicator. Consult with Sika Sarnafil specifications.
