|I brushed on some oil based gesso to add texture and test adhesion|
PREPARING THE PANEL FOR MOUNTING AND PAINTINGI have done some tests with them. Not really all that scientific, or exhaustive, but my initial impression is that they work quite well as painting supports with no real preparation. If you are concerned with the archival nature of them, you will want to test them with your materials to make sure they suit your needs.
Note: Use only the coated side of the panel for painting and mounting.
- Remove the protective film from the coated side slowly and carefully to avoid static build-up.
- Pre-clean the panel surface with ethyl or isopropyl alcohol, using non-colored cloth for best results. It is important not to use solvents, soaps or liquid cleaning materials as they may leave a film residue that can affect adhesion. Additionally, cleaners containing silicone can interfere with adhesion and are not recommended. A 70% solution of isopropyl alcohol is recommended as the only cleaning material.
- Scuff the surface with abrasive paper, preferably using a grain size of 360 grit. Do not grind through the coating to the aluminum metal.
- Remove dust with a lint-free cloth moistened with ethyl or isopropyl alcohol.
|Very smooth surface. No preparation, just painting directly on to polyester surface.|
