Unlock Woodworking Magic: Mastering Dewaxed Shellac Timing!

Understanding Dewaxed Shellac

Dewaxed shellac, a classic in woodworking, is best for projects that won’t encounter much moisture or alcohol. Why? Because shellac isn’t the best at resisting these elements. You can use dewaxed shellac between stain layers, or even before applying lacquer or polyurethane sealants. Think of it as a great pre-sealant option!

Now, I’ve seen many fellow woodworkers use dewaxed shellac as the main sealant. While their enthusiasm is commendable, it’s not the ideal choice. Over time, you’ll see why. Whether you’re a hobbyist or a seasoned pro, understanding when to apply dewaxed shellac is key.

When to Apply Dewaxed Shellac

  • For Non-Water Exposed Pieces: If you’re crafting a decorative piece that won’t face water or alcohol spills, dewaxed shellac can be your go-to. It won’t offer top-notch protection, but it can certainly add charm to decorative items.
  • As a Pre-Sealant: Dewaxed shellac shines as a pre-sealant. It can enhance the wood grain, giving your piece that extra glow. After applying, sand it down and top it with a more durable sealant like lacquer or polyurethane for both beauty and strength.
  • Between Finish or Stain Layers: Use dewaxed shellac between finish or stain layers to prevent uneven absorption. It acts as a barrier, ensuring your stain or finish is evenly distributed, resulting in a more aesthetically pleasing outcome.

Limitations of Dewaxed Shellac

It’s essential to note that dewaxed shellac won’t make wood waterproof. It offers a modicum of protection against occasional water splashes, but for serious water resistance, you’ll need a sturdier sealant.

What can go over shellac? Lacquer and polyurethane are your best bets. They enhance durability, water resistance, and longevity, ensuring your masterpiece withstands the test of time.

Choosing the Right Shellac Brand

For shellac, you have two routes: traditional shellac flakes or ready-to-use dewaxed shellac. If you prefer flakes, I recommend De-Waxed Super Blonde Shellac Flakes. If ready-made is more your style, Rust-Oleum Zinsser 854 1-Quart Bulls Eye Sealcoat Universal Sanding Sealer is a great dewaxed option.
