Here’s how to use it:

Heat the shellac sticks to melt them away. Hold the shellac stick above a knife on top of the heat source until it turns soft with putty or glazing compound consistency.

  1. Put the mush on areas you’re going to patch, and let it sit for an hour or two once it turns hard enough, smooth, and levels up the surface by using plane or sand.
  2. Typically, you do not need to retouch the surrounding of the break. However, you may coat the surface with more shellac if you want.
  3. If you feel like the hole is too large, it is possible to get it filled by a cut and trimmed piece of wood. Make sure the cut piece can fit the hold perfectly.

As some glue types like carpenter’s glue or PVA may discolor the sawdust, it is important to know the correct type of glue. Otherwise, you may get the final result colored in gray or dull yellow.

Wood flour cement is the best glue for this use. It is a kind of epoxy adhesive. You may opt for the old clear epoxy, clear polyurethane, or lacquer by only using a handful amount.

Combine the adhesive with sawdust to create a paste in thick consistency, and put it on the hole before the liquid sets.

Filling Large Holes in Wood with Epoxy

Epoxy is the most common material used to patch rather large holes. It can repair different wood material types such as sills, moldings, baseboards, or trim with damage or holes. Below is a tutorial on how to fill large holes in wood using epoxy:

  1. Find some support so the patch can stick, such as a Popsicle stick. Attach it to the back of the hole.
  2. Mix the epoxy while waiting for the glue to dry.
  3. Combine filler and hardener according to the direction on the epoxy can.
  4. Apply to the hole once the mix turns into orange color.

For a smoother finish, use sandpaper, then paint the patch in a similar color as the wood. The epoxy material on filling large holes in the wood above can be used on walls or furniture.
