How to Apply a Natural Finish on Softwoods: Examples: Pine, Cedar, Poplar, etc.
How to apply this finish: 1. Sand the project up through the grits until at least 220-grit a. It is a good idea to sand pieces that will be hard to reach before assembly. 2. Wipe the project with mineral spirits to check for glue splotches 3. Apply a sealer coat (Zinsser Sealcoat) of a shellac-based finish by wiping: flooding the surface with finish and wiping it off. 4. If you have any nail holes, cracks or defects in the wood, fill them now with a wood filler putty that matches the color of the oiled wood (sand smooth) 5. Apply at least two coats of a wipe-on polyurethane 6. Optional: After the finish has cured for 72 hours, apply a coat of high-quality paste wax and then polish it off.
