Liberon Shellac Filler Sticks - 3 Pack - Brown

No, Liberon Shellac Filler Sticks are intended for cosmetic repairs of surface imperfections like small holes and cracks, not for structural reinforcement.

The filler sticks come in intermixable shades. Experiment by blending small amounts of the different colors on a palette or scrap piece of wood until you achieve the desired tone that matches your project.

You can melt the stick directly onto the imperfection or into a heated palette knife. Apply the molten filler to fill the defect, slightly overfilling, and allow it to cool before scraping or sanding flush.

Yes, once the filler has completely cooled and hardened, you can carefully sand it flush with the surrounding surface. Be cautious not to over-sand and damage the wood.

These filler sticks are compatible with most wood finishes and are designed to be used before applying French polish, lacquer, or varnish. They can be used on both finished and unfinished wood.

Store the filler sticks in a cool, dry place away from direct sunlight to maintain their consistency and prevent them from becoming brittle or melting.

When stored correctly in a cool, dry place, shellac filler sticks have a very long shelf life, remaining effective for many years.

Ensure the wood surface is clean, dry, and free from dust or grease. For existing finishes, a light scuff sanding might improve adhesion.

This can happen with very deep fills. Try applying the filler in thin layers, allowing each layer to cool slightly before applying the next. Ensure the filler is fully hardened before attempting to smooth it.

Experiment with mixing the different provided shades on a separate surface before applying to the wood. Allow mixed filler to cool to see its true color.

Ensure you are using an appropriate heat source if using a heated knife. If melting directly onto the wood, apply heat consistently but avoid scorching the wood.
