Finally, wipe down the wood with a damp cloth to remove any dust or debris before applying a primer and paint. **

Regular maintenance and proper care can help extend the lifespan of untreated Douglas fir. **

Regular maintenance and reapplication of these protective coatings are essential to ensure long-lasting protection for untreated wood. **
