Craft cork for miniature bases is often used in model building and scale models as a material for creating terrains, such as hills and mountains, and other diorama landscapes. Cork for miniature bases can also be used to create texture on the surface of models, such as scenery manufacturing, entire army bases, or even theming dioramas or scale models. Additionally, this material cut in sheets or into grit is a lightweight and easy-to-shape material that can be cut and sanded to create a variety of different textures and forms.

How to create miniature bases with cork sheets

This modeling material is used in broken pieces and glued together with modeling glue is one of the most basic techniques for decorating miniature bases.


  1. Start by cutting the sheets into the desired shape and size for your miniature bases. You can use scissors or a hobby knife to do this.
  2. Apply a thin layer of PVA glue to the top of the base.
  3. Carefully place the material in pieces onto your base, pressing it down firmly to ensure a good bond.
  4. Allow the PVA glue to dry, normally it takes around 24 hours.
  5. Once the glue is dry, you can use sandpaper to smooth out any rough edges to make it look more natural texture.

How to paint miniature cork bases

Painting the bases with acrylic paints is a great way to add realism and detail to your dioramas. 

Here are the steps you can follow to paint them:

  1. Start by priming with a white or light-colored primer. This will help the paint adhere better and will also make the colors more vibrant.
  2. Once the primer is dry, you can start applying your base coat. Choose colors that match the terrain you are creating, such as greens for grass or browns for dirt. Use a brush or a sponge to apply the paint, making sure to cover the entire surface of the base.
  3. Once the basecoat is dry, you can start adding highlights and shadows to create depth and dimension. Use a dry brushing technique to apply a lighter color of paint to the raised areas, and a darker color to the recessed areas.
  4. To add even more detail, you can use a fine brush to add small details such as rocks, flowers, or blades of grass.
  5. Once you are satisfied with the results, you can seal the paint with a clear coat of varnish to protect it and make it more durable.
  6. Finally, you can add miniature figures and other elements to your diorama, positioning them on the bases to create a realistic scene.

Note: Acrylic paints dry quickly, so you can work on multiple bases at the same time, just be aware of the drying time when you are adding multiple layers.

What is the best sealer to seal cork miniature basing?

When it comes to sealing cork miniature basing for tabletop gaming, several sealers can be used effectively, and the choice often depends on personal preferences and desired outcomes. Here are a few common options:

  1. Water-Based Polyurethane Varnish: Water-based polyurethane varnish is a popular choice among miniature painters for sealing all types of surfaces. It provides a clear, durable, and protective finish that adheres well. It dries relatively quickly and doesn't yellow over time, making it an excellent option for preserving the natural appearance of a painted model while providing a smooth surface for painting.
  2. Decoupage Medium: Also called Mod Podge, this is a versatile adhesive and sealer that comes in both matte and gloss finishes. It's easy to apply and dries clear. Many hobbyists use Mod Podge, particularly the matte version to seal them. It provides a decent level of protection and can be painted over once dry.
  3. Acrylic Mediums: Acrylic mediums, such as matte or gloss gel mediums, can be mixed with acrylic paint to create a sealer. This DIY sealer can be applied with a paintbrush and airbrush to provide a protective and paintable surface. Mix the medium with water to achieve the desired consistency and apply it.
  4. Spray varnishes: Some hobbyists opt for spray sealers, such as matte or gloss acrylic sprays. These are convenient for applying an even coat. However, be cautious when using spray sealers, as overspray can affect nearby surfaces, and it's essential to use them in a well-ventilated area.

When selecting a sealer, consider factors like the finish (matte, gloss, or satin), your painting preferences, and the level of protection you want for your bases. Ultimately, the best sealer for miniature cork bases can vary from person to person, so it's a good idea to experiment with different options to find the one that works best for your specific needs and desired results.
