Setting chalk pastels is straightforward and essential to prevent smudging and preserve your artwork. The primary method involves using a fixative.
Understanding the Need for Fixative
Chalk pastels, being a dry medium, are susceptible to smudging and losing pigment if not properly protected. A fixative essentially binds the pastel particles to the paper or canvas, making the artwork more stable.
How to Apply Fixative
The most common and accessible method for setting chalk pastels involves using a fixative spray. Here's how to do it:
Materials You'll Need:
- Your chalk pastel artwork
- Fixative spray (aerosol hair spray can be used as an inexpensive alternative)
- A well-ventilated area
- Optional: Mask or respirator
Steps for Applying Fixative:
- Prepare your workspace: Ensure you are in a well-ventilated area, as fixatives can have strong fumes. Consider wearing a mask or respirator to avoid inhaling the spray.
- Position your artwork: Place your pastel artwork on a flat surface.
- Shake the fixative: Shake the can well before use.
- Test spray: Before applying to your artwork, test the spray on a scrap piece of paper to ensure it's not spraying unevenly or too heavily.
- Apply a light coat: Hold the can about 12-18 inches away from the artwork and spray a light, even coat. Avoid spraying too much in one area, which can cause the pastel colors to run or become saturated.
- Allow to dry: Let the fixative dry completely. This may take a few minutes.
- Repeat if necessary: If needed, apply a second very light coat once the first is dry. Avoid over-spraying.
- Final Drying: Allow the artwork to dry completely before handling.
Types of Fixatives
While specialized art fixatives are available, a simple, inexpensive alternative such as aerosol hair spray can also be effective for setting chalk pastels, as mentioned in our reference.
| Fixative Type | Pros | Cons |
|---|---|---|
| Art Fixative Sprays | Specifically designed for art; may offer archival quality and UV protection | Can be more expensive |
| Aerosol Hair Spray | Inexpensive; readily available | May not be archival quality; might alter some pastel colors or textures |
Important Considerations
- Always work in a well-ventilated area to avoid inhaling harmful fumes.
- Apply fixative in light coats rather than one heavy coat to prevent damage to your artwork.
- Test your fixative on a scrap piece of paper before applying it to your artwork.
By following these steps, you can effectively set your chalk pastel artwork, preventing smudging and ensuring its longevity.
