How to Seal Watercolor Painting

Let’s go through the step-by-step process for sealing a watercolor painting:

Materials Needed

  1. Watercolor painting
  2. Fixative spray (matte or satin finish)
  3. Workable fixative (optional)
  4. Masking tape
  5. Drop cloth or newspaper
  6. Well-ventilated area or outdoor space
  7. Gloves (optional)
  8. Soft brush or air bulb (for removing dust)

Step 1: Choose the Right Fixative

Select a fixative spray suitable for watercolors. Choose between matte and satin finishes based on your preference. A Matte finish provides a non-reflective surface, while a satin finish offers a subtle sheen.

Step 2: Prepare Your Workspace

Cover your workspace with a drop cloth or newspapers to protect surfaces from overspray. Make sure you’re in a well-ventilated area or, preferably, work outdoors.

Step 3: Secure Your Painting

Use masking tape to secure the edges of your watercolor painting to a board or a flat surface. This prevents the painting from moving during the spraying process.

Step 4: Clean Your Painting

Ensure your painting is free from dust or loose particles. Gently use a soft brush or air bulb to remove any debris. This step is crucial to prevent unwanted particles from getting sealed onto the painting.

Step 5: Test the Fixative

Before applying the fixative to your actual painting, test it on a small, inconspicuous area or a scrap piece of watercolor paper. This helps ensure that the fixative won’t react negatively to your artwork.

Step 6: Apply Workable Fixative (Optional)

If you want to make corrections or add more layers to your painting in the future, consider using a workable fixative first. This allows you to make changes without damaging the underlying layers.

Step 7: Apply Fixative Spray

Hold the fixative spray can approximately 12-18 inches away from the painting. In a sweeping motion, spray a light, even coat over the entire surface. Be sure not to oversaturate or apply too much fixative at once. Allow it to dry completely before applying additional coats.

Step 8: Apply Additional Coats (Optional)

Depending on your preference, you can apply multiple coats of fixative for added protection. Ensure each layer is dehydrated before applying the next one.

Step 9: Let the Painting Dry Completely

Allow your watercolor painting to dry completely before handling or framing. Depending on the climate and the number of fixative coats applied, this may take a few hours.

Step 10: Remove Masking Tape

Once the painting is fully dry, carefully remove the masking tape from the edges. This reveals the clean borders of your sealed watercolor masterpiece.
