When painting cornice, there are several things to avoid to ensure a successful outcome:

1. Do not paint over a dirty or greasy surface. Clean the surface thoroughly before painting to remove any dust, dirt, or debris.

2. Do not paint over any flaking or peeling paint. Sand the surface lightly to remove any loose paint before painting.

3. Do not paint over a surface that is not dry. Allow the surface to dry completely before applying paint.

4. Do not use paint that is old or has been stored for an extended period of time. Old paint may have lost its ability to adhere properly or may have changed consistency.

5. Do not apply paint too thickly or in a heavy coat. This can result in drips and runs, and can also make it difficult for the paint to dry and cure properly.

7. Do not use a paintbrush or roller that is not specifically designed for use with the type of paint you are using.
