How do you change the color of wood?

Published in Wood Finishing 2 mins read

You can change the color of wood using various methods, primarily involving the application of stains, paints, or other finishing products.

Methods for Changing Wood Color

Here's a breakdown of the common ways to alter the color of wood:

1. Staining

Staining involves applying a colored liquid that penetrates the wood's surface, highlighting its natural grain and adding color.

  • Types of Stains: Oil-based stains, water-based stains, gel stains. Each type offers different levels of penetration and color intensity.
  • Application: Apply stain evenly with a brush, rag, or sprayer. Wipe off excess stain to control the depth of color.
  • Considerations: The original color and type of wood greatly influence the final color after staining. Always test the stain on a hidden area first.

2. Painting

Painting completely covers the wood's surface with a layer of pigmented coating, obscuring the natural grain.

  • Types of Paints: Latex, acrylic, oil-based, enamel. The choice depends on the desired finish, durability, and application.
  • Application: Apply paint in thin, even coats with a brush, roller, or sprayer. Sand lightly between coats for a smoother finish.
  • Considerations: Proper preparation (sanding, priming) is crucial for paint adhesion and a professional-looking result.

3. Other Coloring Methods

  • Wood Bleach: Lightens the wood's natural color or removes stains.
  • Wood Dyes: Similar to stains but offer more vibrant and consistent color. They tend to be more transparent.
  • Varnishes and Polyurethanes with Tint: Protective topcoats that can add a subtle tint to the wood.
  • Ebonizing: A process to turn wood black, usually with iron acetate.

4. Altering Existing Finishes

  • Staining Over Existing Paint: While possible, it's generally recommended to remove the paint first for a natural look. Applying stain over paint is possible if the wood is clean and dry. If you stain over paint, the stain will behave more like a tinted varnish.
  • Stripping and Refinishing: Removing the old finish (paint or stain) allows you to apply a new color directly to the bare wood.

Preparation is Key

Regardless of the method you choose, proper preparation is essential for achieving the desired result:

  1. Cleaning: Remove dirt, grease, and other contaminants.
  2. Sanding: Smooth the surface and create a "tooth" for better adhesion.
  3. Priming (for painting): Apply a primer to seal the wood and improve paint adhesion.
  4. Testing: Always test your chosen method and color on a hidden area of the wood to ensure you achieve the desired result.
