How to varnish an exterior wood door

  1. The first step is to sand the door to eliminate any uneven portions. Make sure to sand in the direction of the grain. The optimal sandpaper will be 220-grit sandpaper. If the surface has been varnished before, you will only need to use 80-grit sandpaper. Keep working on the door until it is smooth.
  2. Use a damp cloth to take care of the dust and residue left behind from sanding. Make sure you remove most of the debris.
  3. It’s best to thin the varnish to prevent bubbles from forming on the surface. Combine the varnish with mineral spirits to thin it. The ratio should be 50:50. Add the solution to the raw wood and even out any bubbles before drying out.
  4. Apply the varnish using a broad nylon brush. Make sure to follow the grain of the wood when varnishing. It will be most effective to start at one corner of the door and continue to the dry areas.
  5. Give the varnish about 24 hours to dry.
  6. You can finish off the varnish process with light sand. This process will help to remove any dust.
  7. You can continue to add coats until you are happy with the job. About four coats should be enough.
