Application Instructions
Surface Preparation
All surfaces must be clean, dry and free from oil, grease and all loosely adhering particles. Glass, stainless steel, aluminium and other metals must be degreased with alcohol based or MEK based solvents.
Back Up Material
Use closed cell polyethylene profiles, maintain a straight with proper edges that can receive a sealant having width to depth ratio of 2:1 accounting for the thickness of the backing rod.
Primer Application
Primer is not required, however for porous surfaces such as concrete and other alkaline surfaces prime using MASTER COATING primer PU which is a one-component polyurethane primer. Apply the primer on the sides of the clean, dry s using brush. Allow the primer to become tacky (20-30min) before applying sealant MASTER COATING Plyflex 1200.
