Application
APPLICATION
Sarnafil® G 410-72 EnergySmart is installed by a Sika® Canada Authorized Applicator. After proper preparation of the substrate, the membrane is unrolled into Sarnacol adhesive in accordance with Sika Canada’s Technical requirements and then pressed into place with a minimum 45 kg (100 lb) linoleum roller. The membrane seams are then heat-welded together by trained operators using Sika® Sarnafil®’s hot-air welding equipment. Note that different Sarnacol adhesives require different application methods. Consult Sika Canada’s Applicator Handbook for detailed installation procedures
