How to Seal White Washed Wood

What is White Washed Wood?

White washing is a technique that gives wood a faded, weathered look by applying a diluted white paint or stain. This method is popular for achieving a shabby chic or coastal style in home decor. While it enhances the visual appeal, white washed wood needs to be properly sealed to prevent damage and preserve its finish.

Why Seal White Washed Wood?

Sealing white washed wood serves several purposes:

  1. Protection: It safeguards the wood from moisture, stains, and scratches.
  2. Durability: A good sealant can prolong the life of the wood by providing a durable barrier.
  3. Aesthetic Preservation: Sealing maintains the fresh, white washed look by preventing the finish from fading or yellowing over time.

How to Seal White Washed Wood: Step-by-Step Guide

Step 1: Choose the Right Sealant

Selecting the appropriate sealant is crucial. Here are some popular options:

  • Polyurethane: Provides a tough, durable finish. Available in oil-based and water-based formulas.
  • Polycrylic: Water-based, less likely to yellow over time, and suitable for lighter finishes.
  • Wax: Offers a natural finish but requires more frequent maintenance.
  • Lacquer: Dries quickly and gives a high-gloss finish but can be tricky to apply.

Step 2: Prepare the Surface

  1. Clean the Wood: Ensure the wood surface is clean and free of dust and debris.
  2. Sand the Wood: Lightly sand the surface with fine-grit sandpaper (220 grit) to create a smooth base.
  3. Remove Dust: Wipe away sanding dust with a tack cloth or damp rag.

Step 3: Apply the Sealant

  1. Test the Sealant: Always test the sealant on a small, inconspicuous area to ensure it doesn’t alter the white washed appearance.
  2. First Coat: Apply the first coat of sealant using a high-quality brush, foam brush, or roller. Follow the grain of the wood for best results.
  3. Drying Time:This usually takes 2-4 hours for water-based sealants and up to 24 hours for oil-based sealants.

Step 4: Sand Between Coats

  1. Light Sanding: Lightly sand the surface with fine-grit sandpaper (320 grit) between coats to ensure a smooth finish.
  2. Remove Dust: Clean off the sanding dust with a tack cloth.

Step 5: Apply Additional Coats

  1. Second Coat: Apply a second coat of sealant and allow it to dry. Repeat the process of sanding and applying additional coats as needed.

Step 6: Final Touches

  1. Final Sanding: After the last coat has dried, lightly sand the surface one final time for a smooth finish.
  2. Clean and Inspect: Wipe down the surface, inspect for any missed spots, and touch up if necessary.
