How to make paintings glossy

Making a painting glossy involves applying a finish or varnish that adds a shiny, protective layer. The process varies slightly depending on the type of paint and the surface.

Materials Needed:

1. Gloss Varnish: Choose a varnish suitable for your type of paint (e.g., acrylic varnish, oil varnish, or spray varnish).
2. Soft Brush: Use a high-quality, soft brush for applying liquid varnish.
3. Spray Varnish: An alternative for those who prefer a spray application.
4. Clean Cloth: For cleaning and dusting the painting surface.
5. Well-Ventilated Area: Ensure you work in a well-ventilated space, especially when using spray varnish or varnish with strong fumes.

Steps for Acrylic Paintings:

1. Prepare the Painting: Ensure the painting is completely dry and free from dust. Use a clean, dry cloth to gently wipe the surface.
2. Select a Varnish: Choose a gloss acrylic varnish. Popular options include Golden Polymer Varnish or Liquitex Acrylic Varnish.
3. Apply the Varnish:
   • Liquid Varnish: Pour a small amount of varnish into a clean container. Dip the soft brush into the varnish, removing any excess. Apply the varnish in thin, even strokes, working in one direction (e.g., horizontal). Allow to dry and apply a second coat, working in the opposite direction (e.g., vertical).
   • Spray Varnish: Shake the can well. Hold it about 12 inches from the surface and spray in a steady, back-and-forth motion. Apply multiple thin coats rather than one thick coat, allowing each layer to dry before applying the next.

Steps for Oil Paintings:

1. Ensure Dryness: Oil paintings must be completely dry, which can take several months to a year.
2. Select a Varnish: Choose a gloss varnish designed for oil paintings, like Gamvar or Winsor & Newton Artists’ Gloss Varnish.
3. Apply the Varnish:
   • Pour a small amount of varnish into a clean container.
   • Dip a soft brush into the varnish, removing any excess.
   • Apply the varnish in thin, even strokes, working in one direction. Avoid over-brushing.
   • Allow the varnish to dry completely before applying additional coats if needed.

Additional Tips:

• Test First: Always test the varnish on a small, inconspicuous area of the painting to ensure compatibility and desired finish.
• Proper Environment: Apply varnish in a dust-free environment to avoid particles sticking to the wet surface.
• Drying Time: Follow the manufacturer’s instructions for drying times between coats. Generally, acrylic varnish dries faster than oil varnish.
• Avoid Yellowing: Choose non-yellowing varnishes to ensure your painting retains its original colors.
