Achieve the Perfect Finish for Your Hard Work With Good Polyurethane Technique
Posted On May 29, 2015
Once you’ve completed a wood project, you’ll want to add a polyurethane finish to add both beauty and protection. Use the following tips to finish your wood:
- Make sure you are working in a dust-free setting.
- Apply the stain to your wood and then let it dry.
- If you aren’t using water-based polyurethane, you’ll want to reduce it by 10 percent using mineral spirits. This will reduce brush marks.
- Use a foam brush to apply three thin coats of polyurethane. Let each coat dry completely before adding another one.
- Sand the wood lightly between coats using 320-grit sandpaper wrapped over a hard block. This will give the polyurethane something to bond to.
- Once the third coat has dried, sand it with 320-grit sandpaper followed by 400-grit sandpaper and then finish up by using 600-grit sandpaper. Alternate directions to remove scratches – your final pass should be sanded along with the grain.
- The last coat you’ll add should be applied using an aerosol polyurethane. Let it cure overnight and remove any dust nibs that are present with 1,500-grit sandpaper.
