Reapplying Danish oil to an already finished piece of furniture is a bit different than applying it to unfinished wood. Here are the steps to follow:
1. Clean the surface: Make sure the surface is clean and free of any dust, dirt, or debris. You may need to use a mild detergent or cleaner to remove any build-up or grime.
2. Sand the surface: Use fine-grit sandpaper to lightly sand the surface, being careful not to sand through the existing finish. This will help to create a clean, smooth surface for the new coat of Danish oil to adhere to.
3. Apply the Danish oil: Using a clean, lint-free cloth, apply the Danish oil to the surface in the direction of the grain. Be sure to apply evenly and cover the entire surface. Allow the oil to soak in for 15-20 minutes.
4. Wipe off excess: After the oil has soaked in, use a clean cloth to wipe off any excess oil that has not been absorbed by the wood. Be sure to wipe in the direction of the grain to avoid leaving streaks.
5. Wait for drying: Allow the first coat to dry completely, which may take up to 24 hours depending on the humidity and temperature.
6. Sand and repeat: After the first coat has dried, use fine-grit sandpaper to lightly sand the surface again. Wipe off any dust with a clean, dry cloth, and apply a second coat of Danish oil using the same process as the first. Repeat this process for additional coats if desired, waiting for each coat to dry before sanding and applying the next.
7. Finish and cure: After the final coat has been applied and dried, allow the Danish oil to cure for at least 24 hours before using or handling the surface.
It's important to note that if the existing finish is in good condition, you may not need to sand the surface before applying the new coat of Danish oil. However, if the surface is damaged or worn, sanding may be necessary to create a smooth, even surface for the new coat of oil to adhere to.
It's important to note that Danish oil can be flammable, so be sure to follow all safety instructions and keep the area well-ventilated during application and drying.
