Packing and Storage Mascoat~dB should be kept in a storage area above 32F (OC). Product can be reused if sealed correctly. It is best to keep the container out of direct sunlight for sustained periods.
Surface Preparation
For aluminum and stainless surfaces:
Clean surfaces prior to application of Mascoat.
Slight sanding or grinding can be used to give product tooth.
For Carbon steel surfaces:
Use primer capable of the highest peak temperature.
Zinc and epoxies usually perform best in higher temperatures and industrial type environments. Please contact Mascoat if a primer is needed.
Methods of application:
Spraying: Use airless spray methods as defined by recommended sprayers.
SA Gun for small applications.
Rolling: Use low to medium mat roller.
Brushing: Use nylon of bristle brush capable of water based coatings.
