How to Apply Shellac: 8 Steps
Applying shellac to wood can be a tricky process, but with some preparation and patience, you can create a beautiful finish that will last for years. Shellac is an excellent choice for woodwork because it is durable, easy to maintain, and provides a smooth finish. Follow these eight steps to apply shellac correctly.
1. Prepare the surface: Before you apply shellac, it’s essential to clean the wood surface thoroughly. Sand the wood using 220-grit sandpaper to remove any imperfections or previous finishes and then remove any residual dust with a damp cloth. In case of larger projects, use a vacuum cleaner for better dust removal.
2. Choose your shellac: Shellac comes in various colors and types, so pick one according to your preference and the desired finish. You can purchase pre-mixed shellac or mix it yourself using shellac flakes and denatured alcohol.
3. Mix the shellac: If you are mixing your shellac from flakes, mix it in a glass jar by adding denatured alcohol slowly until you reach the desired consistency. It is best to follow the manufacturer’s instructions during this process.
4. Prepare your workspace: Make sure you have a well-ventilated area to work in as applying shellac can produce strong fumes. Also, gather all the necessary supplies such as brushes, applicators, mineral spirits, clean rags, gloves, and 400-grit sandpaper.
5. Apply the first coat: Starting at one end of the piece and working your way across, use a high-quality brush or lint-free cloth to apply a thin layer of shellac in long strokes along the grain of the wood. Work quickly as shellac dries fast.
6. Allow each coat to dry: It’s crucial to let each layer of shellac dry completely before proceeding with subsequent coats. Refer to the manufacturer’s recommendations for drying time, which generally ranges from 30 minutes to an hour, depending on the humidity.
7. Lightly sand between coats: After each coat has dried thoroughly, use 400-grit sandpaper to lightly sand the surface. This step ensures better adhesion between layers and helps you achieve a smooth finish. Wipe away any dust with a clean cloth.
8. Apply subsequent coats: Apply additional coats of shellac following steps 5-7 until you achieve your desired level of sheen and color. Typically, three or four coats are enough for most wood surfaces.
Once you’ve finished applying the final layer of shellac and it has dried completely, your project is complete! Now you can enjoy the beautiful, durable finish that shellac offers for years to come.
