Wood Finishing Materials: Everything You Need for a Perfect Finish

Whether you're building a bookshelf, restoring an antique table, or crafting a custom cabinet, wood finishing materials are what bring out the beauty in your work. A good finish not only enhances the appearance of the wood but also protects it from wear, moisture, and aging.

With so many products available, it’s easy to feel overwhelmed. This guide breaks down the most common wood finishing materials, what they do, and when to use them—so your next project turns out exactly how you imagined.

1. Wood Stains

Wood stains are used to add color to bare wood while still allowing the grain to show through. They come in a range of shades from natural browns and reds to bold tones like blue or green.

Types:

  • Oil-based stains: Rich color, slow drying, deep penetration.
  • Water-based stains: Fast drying, low odor, easier to clean.
  • Gel stains: Thicker consistency, great for vertical surfaces or uneven woods.

Best for: Coloring furniture, trim, cabinetry, and decorative pieces.

2. Wood Sealers

Sealants protect the wood from absorbing moisture and help even out the surface before applying a finish.

Common Types:

  • Sanding sealer: Applied before topcoats, helps create a smoother base.
  • Dewaxed shellac: Used as a universal sealer, especially when bonding incompatible products.

Best for: Prepping soft woods like pine or preventing blotchiness when staining.

3. Topcoats and Finishes

Topcoats are protective layers that sit on top of the wood and give it durability and sheen. They come in several finishes—matte, satin, semi-gloss, and high gloss.

Popular Options:

  • Polyurethane (oil- or water-based): Tough, durable, great for floors and tabletops.
  • Lacquer: Fast-drying, gives a smooth, clear finish; commonly used in furniture and cabinetry.
  • Varnish: Durable and UV-resistant, ideal for outdoor furniture.
  • Shellac: Natural and non-toxic, but less water-resistant.
  • Wax: Soft, low-sheen finish, used as a topcoat or for touch-ups.

Best for: Protecting against scratches, moisture, and daily wear.

4. Wood Oils

Wood oils penetrate the surface and condition the wood while offering mild protection and a natural look.

Types:

  • Tung oil: Hard-drying, water-resistant, and food-safe.
  • Linseed oil: Popular traditional finish; can darken over time.
  • Danish oil: Blend of oil and varnish, gives a durable, natural-looking finish.
  • Mineral oil: Food-safe, used on cutting boards and butcher blocks.

Best for: A soft, hand-rubbed look on decorative or indoor wood items.

5. Fillers and Grain Enhancers

  • Wood filler: Used to fill holes, cracks, and gaps before staining or painting.
  • Grain filler: Smooths open-grain woods (like oak or mahogany) for a glassy finish.
  • Pore filler: Especially useful for high-gloss finishes.

Best for: Repairing and prepping wood for a smooth final appearance.

6. Conditioners and Primers

  • Pre-stain wood conditioner: Helps prevent blotchy stains on soft woods like pine or birch.
  • Primer: Used before paint to ensure better adhesion and color consistency.

Best for: Improving stain and paint results.

Conclusion

Choosing the right wood finishing materials is just as important as the construction of your project. Whether you're aiming for a high-gloss showroom shine or a rustic, natural look, there's a combination of products that can help you get there. Take your time, test on scrap wood, and enjoy the process—because a great finish makes all the difference.
