Soft pastels are set using a fixative spray. This is done to stabilize the pastel media, hold it in place on the paper, and provide protection from dust.
Why Use Fixative?
- Soft pastels are prone to smudging and can easily be disturbed.
- A fixative helps prevent accidental smearing and the loss of pigment.
- It protects pastel artwork for long term display and storage.
How Fixative Works
According to research, fixative contains a fast-drying liquid as a base, typically:
- Alcohol
- Casein
- Resin
These liquids are designed to bind the pastel particles to the surface of the paper.
Step-by-Step Guide to Applying Fixative
- Prepare your workspace: Ensure the area is well-ventilated and free from dust and debris.
- Position your pastel artwork: Place the artwork flat on a protected surface, like a piece of cardboard.
- Test the fixative: Before spraying on the artwork, test the fixative on a separate piece of paper. This helps you gauge spray pattern and amount.
- Hold the fixative can 10-12 inches away from the artwork: Apply in light, even, and consistent strokes. Avoid applying too much at once, to prevent running of the fixative and pastel colors.
- Apply thin, multiple coats: Instead of one heavy coat, apply several light coats, allowing each to dry before applying the next. Allow each coat to dry before applying the next.
- Dry thoroughly: Allow the artwork to dry completely before touching or handling it. Drying time depends on the product and temperature.
- Store safely: Once dry, store the art work flat, with an acid free paper overlay.
Important Considerations
- Type of Fixative: There are different types of fixatives available, so choose the one that's best suited for pastels.
- Ventilation: Always use fixatives in a well-ventilated area, as the fumes can be harmful.
- Light application: Use a light touch, multiple thin coats are much better than one thick coat.
- Drying time: Be patient and allow the fixative to dry thoroughly.
- Color changes: Be aware that fixatives may slightly darken or alter the colors of your pastels.
Types of Fixative
| Fixative Type | Base | Characteristics |
|---|---|---|
| Alcohol-based | Alcohol | Dries quickly, can be less forgiving |
| Casein-based | Casein | Creates a matte finish, more forgiving |
| Resin-based | Resin | Creates a more glossy finish, best suited for final fixative |
By following these steps, you can effectively set soft pastels, preserving their beauty and protecting them from damage.
