How to Properly Gesso Your Paper for Acrylic Painting

 If you're painting with acrylics on paper, one of the most essential steps is priming your surface with gesso. Gesso acts as a barrier between the paint and the paper, preventing the paint from seeping in and causing warping or tearing. Properly applied gesso ensures that your colors remain vibrant, your brushstrokes smooth, and your artwork long-lasting. This guide will walk you through everything you need to know about gessoing paper for acrylic painting.

What Is Gesso and Why Use It?

Gesso is a white paint-like primer made from chalk, gypsum, pigment, and binder. It prepares your surface for paint by creating a slightly textured, absorbent ground. Without gesso, paper can absorb too much moisture from acrylic paint, leading to buckling and an uneven surface.

Benefits of Gesso:

  • Prevents Warping: Especially important on thinner papers.
  • Creates Texture: Adds grip to help paint adhere better.
  • Saves Paint: Reduces absorption so paint sits on top of the surface.
  • Improves Vibrancy: Paints appear brighter and more saturated.

Step-by-Step Guide to Gessoing Watercolor Paper



Materials Needed:

  • Watercolor paper (140 lb/300 gsm or higher)
  • Acrylic gesso (white or clear)
  • Wide flat brush (2–3" bristle brush or foam brush)
  • Paper towels or cloth
  • Painter’s tape or artist tape
  • Board or hard surface to tape the paper to

Instructions:

  1. Choose the Rough Side Most watercolor paper has a textured side and a smooth side. Use the textured side for better adhesion and more interesting paint texture.
  2. Secure the Paper Tape all four edges of your paper to a hard, flat surface like a piece of MDF board or drawing board. Use a "half-on, half-off" tape method to create a clean border.
  3. Apply the First Layer of Gesso
    • Pour a small amount of gesso onto the paper.
    • Use a wide brush to spread it evenly, brushing in one direction.
    • Don’t water down the gesso—apply it full strength for better coverage and protection.
  4. Let It Dry Completely Allow the first coat to dry fully. This usually takes 20–30 minutes, depending on room temperature and humidity.
  5. Apply a Second Coat (Optional)
    • For extra durability and smoothness, apply a second coat.
    • Brush it on perpendicular to the first coat to create a crosshatch pattern.
  6. Check the Edges Ensure gesso reaches all taped edges. If not, the paper may rip when you remove the tape.
  7. Remove the Tape Carefully Once dry, slowly peel back the tape at a 45-degree angle to prevent tearing.

Pro Tips for Gesso Success

  • Clean Your Brush Immediately: Gesso dries fast and can ruin brushes.
  • Use Clear Gesso for Layered Effects: If you want your pencil sketch or background texture to show through, clear gesso is a great option.
  • Try Sanding for a Smooth Finish: Lightly sand between coats with a fine-grit sandpaper for ultra-smooth texture.

When to Skip Gesso

If you're using mixed media or acrylic-specific paper that’s already prepped, you may not need to gesso. Always check the packaging or test a corner first.

Final Thoughts

Taking the time to properly gesso your paper can drastically improve your painting experience. It creates a stronger, more reliable surface, lets your paint glide on smoothly, and ensures that your final piece stands the test of time. Whether you’re sketching a quick study or painting your next masterpiece, starting with a well-prepared surface makes all the difference.
