How to Mix Polymer with Acrylic Paint?
- Gather Materials: Acrylic Paints, Polymer Medium, Mixing Palette or Plate, Palette Knife or Brush.
- Mixing Paint and Polymer Medium: Put the desired amount of acrylic paint on the paint palette. Then apply slowly and a small amount of medium each time. Mix with a palette knife.
- Test the Mixture: Apply a thin layer on paper or cardboard and let it dry to ensure desired results.
- Apply the Mixture: Apply the paint to your artwork with a paintbrush or palette knife. Let it dry completely before applying additional layers.

How to Apply Spray Sealer?
- Prepare the surface: Ensure the top layer is clean and dry.
- Shake the spray sealant can: Shake well before applying.
- Apply the spray sealant: Hold the can 8-10 inches away and spray in a sweeping motion. Apply in thin layers and let it dry between coats.
- Allow the sealant to dry: Allow 4-24 hours before exposing to water.
How to Apply Brush-on Sealing?
- Select the ideal brush-on sealer: Choose a varnish or resin that adheres to acrylic paint.
- Prepare the surface: Clean and dry the surface.
- Apply the Varnish: Apply in a thin and even layer with a clean brush.
- Allow the sealant to dry: Let it dry completely, following the manufacturer’s instructions.
- Apply a second coat: Apply a second coat if necessary for maximum protection.
- Great for large surfaces (spray sealer)
- UV-resistant (brush-on sealer)
- Some spray sealants contain harmful chemicals
