Sarnafil® G 476-60 SA

60 mil thick PVC thermoplastic membrane with a foam backing coated with a pressure-sensitive adhesive

Sarnafil® G 476-60 SA is a self-adhered composite sheet consisting of a reinforced thermoplastic waterproofing and flashing membrane and a foam backing coated with a pressure-sensitive adhesive that can be applied directly to a concrete substrate or other approved substrates.

  • Specially compounded for environments of constant dampness, high alkalinity, exposure to plant roots, fungi, and bacterial organisms, as well as low levels of hydrostatic pressure including ponded water conditions
  • Integral fiberglass mat reinforcement for excellent dimensional stability
  • Heat welded seams for strength and security
  • The closed-cell foam backing acts as a separation layer and an integral cushioning layer allowing the membrane to conform to minor irregularities in the substrate

Product Information

Chemical Base

120-mil (3.0 mm) thick composite sheet composed of a 60 mil (1.5 mm) thick Sarnafil G 476 waterproofing membrane with an integral 60 mil (1.5 mm) closed-cell foam backing with a 2.5" (63.5 mm) selvedge on one side to accommodate heat welding of the seam. The membrane is made of high quality PVC resin, pigments, stabilizers, and additives incorporated and fused into a homogeneous polymer matrix and then coated to both sides of a fiberglass carrier sheet. The foam backing is factory-coated with a pressure sensitive adhesive that is protected by a plastic release liner which is removed during installation.

Reinforcing Material

Fiberglass

Storage Conditions

Store rolls on pallets and fully protected from the weather with clean canvas tarpaulins. Unvented polyethylene tarpaulins are unacceptable due to the accumulation of moisture beneath the tarpaulin in certain weather conditions that may affect membrane weldability.

Application

Application steps

APPLICATION

Sarnafil® G 476-60 SA is installed by an authorized Sika Waterproofing Applicator according to published specifications and details. New concrete shall be cured and dry. Sarnafil® G 476-60 SA is used in conjunction with Surface Conditioner WB or Sarnavap Self-Adhered Primers depending on ambient and surface temperature upon installation. The membrane is used as the primary waterproofing sheet in the Sika Adhered Waterproofing System. Consult with these specifications and details for further information. Sarnafil® G 476-60 SA membrane and flashings must be covered and cannot be left permanently exposed. Typical maximum exposure is limited to 3 months but may vary depending on the location and the time of year. Contact Sika if the anticipated exposure is to exceed 3 months.
