Application
APPLICATION
Make sure Sarnafil® G 410-72 Textured is installed with the textured side of the membrane facing up. Sarnafil® G 410-72 Textured is installed after proper preparation of the approved substrate. The membrane is unrolled into Sarnacol® adhesive in accordance with Sika’s technical requirements and then pressed into place with a minimum 45 kg (100 lb) steel roller. Sarnafil® G 410-72 Texturedseams are heat‐welded together by trained operators using hot‐air welding equipment. Different Sarnacol adhesives require different application methods. Please consult Sika’s Specifications or Applicator Handbook for detailed installation procedures.
