Preserving Charcoal Drawings: How to Seal Them with Spray Resin Varnish Safely and Effectively

Many artists are concerned about protecting their cherished charcoal drawings from wear and tear, particularly when handling them. By applying the right resin varnish, you can seal your charcoal drawings, ensuring they remain vibrant and detailed over time. Here’s a step-by-step guide to help you seal your charcoal drawings without compromising their intricate details.

Steps to Seal Charcoal Drawings

1. Choose the Right Varnish

Selecting the appropriate varnish is crucial for the longevity and preservation of your artwork. Look for a non-yellowing archival-quality resin varnish that is specifically suitable for use on paper and is compatible with charcoal. High-quality varnishes are designed to protect your artwork without altering its appearance over time.

2. Prepare the Surface

To ensure optimal protection, it is essential to properly prepare your drawing before applying the varnish.

Ensure the charcoal drawing is completely dry: Allow ample time for your drawing to dry thoroughly after completion. If you have used any fixative, it is particularly important to let it dry completely to avoid any damage from the varnish. Clean the surface: Gently wipe the surface of the drawing to remove any dust or debris. A soft, lint-free cloth can be used for this purpose.

3. Test First

Always test the varnish on a small, inconspicuous area of scrap paper with similar charcoal application before proceeding to the entire drawing. This will help you determine how the varnish interacts with the texture and appearance of your artwork. This is a critical step to avoid any adverse reactions that could affect your drawing.

4. Apply Fixative

Before applying the varnish, it is advisable to lightly spray a fixative specifically designed for charcoal. This helps to bind the charcoal to the paper and reduces the risk of smudging. Make sure to apply the fixative evenly to cover the entire surface.

5. Spray Application

Apply the varnish in a well-ventilated area or outdoors to prevent any inhaling of fumes. Maintain a distance of about 12-18 inches from the surface. Spray the varnish in light, even coats.

Start with a light misting layer to help the varnish adhere evenly. Gradually build up the layers, allowing each to dry completely before applying the next. Excessive saturation can cause the paper to warp or lose detail.

6. Drying Time

After applying the final coat, leave the drawing to dry according to the manufacturer's instructions. This can take several hours or longer. Ensure that the varnish is fully dry before handling or storing your artwork.

Handling and Storage

Once the varnish is fully dry, your charcoal drawing should be more durable and can be handled with care. Store your artwork flat or in a protective sleeve to prevent damage from physical contact. To avoid any oils from your hands affecting the surface, it is best to handle the drawing by the edges or wear clean gloves.

Additional Tips

7. Avoid Direct Touching

Even with the varnish, it is best to handle your drawing by the edges or with clean gloves to avoid any oils from your hands affecting the surface. Excessive contact can cause oily residues that may damage your artwork over time.

8. Consider Framing

If you are concerned about long-term protection, consider framing your charcoal drawing under glass or acrylic. This minimizes exposure to dust, moisture, and physical handling, providing an additional layer of protection for your artwork.

By following these steps, you can effectively seal your charcoal drawing while maintaining its detail and integrity. Preserve your artwork for future generations and enjoy the satisfaction of knowing it will remain in excellent condition for years to come.
