Application
APPLICATION
Sarnafil® G 410-80 Feltback 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 410-80 Feltback seams are heat‐welded together by trained operators using hot‐air welding equipment. Different Sarnacol adhesives require different application methods. Consult Sika’s Specifications or Applicator Handbook for detailed installation procedures.
