| 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. |
