Applying gesso to your paint by numbers canvas can improve the painting experience and result. To apply gesso, prepare your workspace, thin the gesso slightly if needed, and apply it evenly in thin coats across the canvas surface.
Why Use Gesso on Paint by Numbers?
Many paint by numbers kits come with a pre-primed canvas, but sometimes an extra layer of gesso can enhance the surface. Gesso serves several purposes:
- Creates a Smoother Surface: Helps paint glide more easily.
- Provides Better Adhesion: Allows paint to stick firmly to the canvas.
- Prevents Bleed-Through: Stops paint from soaking excessively into the fabric.
- Brightens Colors: Provides a clean, white base that makes colors appear more vibrant.
Steps for Applying Gesso
Applying gesso is a straightforward process. Here’s how to do it effectively for your paint by numbers project:
Step 1: Prepare Your Workspace
Lay down newspaper or a drop cloth to protect your surface. Have your gesso, a brush (a flat, synthetic brush works well), and a small amount of water ready if thinning is required.
Step 2: Prepare the Gesso
Stir the gesso thoroughly. If it seems too thick, you can add a tiny amount of water (just enough to make it spreadable, not runny). Aim for a creamy consistency.
Step 3: Apply the First Coat
Dip your brush into the gesso and remove any excess. Start applying a thin, even coat across the canvas. Work in one direction (e.g., horizontally). Cover the entire numbered area.
Step 4: Smooth the Surface
Once the first coat is applied, you can go back over it lightly to smooth out brush marks. As the reference suggests: "Go over the canvas in both directions just very lightly, without adding more gesso to smooth out the marks." This helps achieve a more uniform surface.
Step 5: Let it Dry (Crucially!)
Allow the gesso to dry completely. The reference emphasizes this point: "The best thing to do is to then leave your canvas to completely dry for 24 hours before starting to apply your paints." Proper drying time is essential for the gesso to cure and provide a stable surface.
Step 6: Apply Additional Coats (Optional)
For an even smoother surface or if the canvas texture is very rough, you can apply a second thin coat after the first one is fully dry. Repeat steps 3-5, applying the second coat in the opposite direction (e.g., vertically) to the first.
Tips for Best Results
- Always apply gesso in thin coats rather than one thick layer.
- Ensure your brush is clean before starting.
- Check that the canvas is completely dry before painting – waiting the full 24 hours is recommended.
- Clean your brush immediately after use with soap and water.
Using gesso can significantly improve the quality of your paint by numbers artwork by providing a superior surface for paint application and enhancing the final look of your colors.
