Application steps

APPLICATION

Sarnafil S 327 is rolled out onto the insulation board or acceptable substrate, flipped over in order to reveal textured side of membrane as the top surface, fastened to the roof deck with appropriate plates and fasteners, and heat‐welded together by trained operators using hot‐air welding equipment. Please consult Sika’s Specification or Applicator Handbook for detailed installation procedures.
