Preserving chalk pastel artwork primarily involves protecting the delicate pigment layers from smudging and environmental factors. The most common and effective method is using a fixative.
Utilizing Aerosol Fixative
A key technique for preserving your chalk pastel artwork is applying aerosol fixative. This spray-on solution is designed to form a protective barrier over your finished piece.
How it works:
- It creates a shield that guards your artwork against smudging, a common issue with the loose pigment of chalk pastels.
- It helps in preserving the vibrant colors of your pastels for years to come, preventing them from being easily disturbed.
Application Steps:
To ensure an even and effective application, follow these steps:
- Ensure your artwork is completely finished and dry.
- Hold the aerosol can about 12 inches away from your artwork.
- Maintain a 40-degree angle from the surface of the artwork.
- Apply the spray in a steady, even motion across the entire piece. You may need multiple light coats rather than one heavy one, allowing drying time between layers.
- Work in a well-ventilated area.
Proper application of a fixative helps to stabilize the pastel particles, significantly extending the life and appearance of your artwork.
