How to Paint Wood Fascia Boards
Fascia boards are the thin wooden boards that run along a building under the guttering. Their purpose is to protect the air vents leading into the roof space from rain and debris. Because fascia boards are exposed to the weather, they need regular maintenance to prevent them from rotting. This means repainting them every six years or so. This is a job for the summer, since it needs dry weather.
Step 1: Tarpaulin
Start by spreading the tarpaulin under the work area. Scraping off old paint is a messy business. You don’t want paint scrapings all over the yard.
Step 2: Guttering
If at all possible, remove the guttering first. It isn’t essential, but it makes the job easier. Be careful and clean it out before you start. You don’t want all of last winter’s wet leaves to get in your way.
Step 3: Paint Removal
Use the heat gun to soften the old paint and scrape it off the fascia boards with your scrapers. This is a messy, but essential job. If you discover that the scraper goes right into the wood, the wood is rotten. If this is the case, you will need to replace the entire board.
Step 4: Filling
Fill any small holes in the fascia board with wood filler. Keep it aside for an hour and let it dry. Once done, it's time to sand it down.
Step 5: Sanding
Sand down the boards until they are smooth and ready to receive the paint. You will need to start with a coarse disc and then use a medium one.
Step 6: Preservative
Treat the fascia with a wood preservative. You can either spray it on or use a brush to apply it. Keep it aside and let it dry overnight.
Step 7: Primer
Now comes the fun bit. Paint the fascia boards with primer. Don’t overload your brush—the rule is “little and often.” Read the instructions on the paint tin to find how long it needs to dry—sometimes up to 16 hours. Clean your brush after use in a jar full of paint cleaner. If you don’t clean your brushes, they will become useless.
Step 8: Sanding
Once the paint is dry, sand the boards lightly with a medium disc.
Step 9: Undercoat
You now give the fascia a second coat of primer. Clean your brush. After the primer is dry, sand down this second coat with a fine sanding disc. The fascia boards should now be smooth, clean and ready for the paint.
Step 10: Final Coat
Now apply the final gloss coat, clean your brush, replace the guttering once the paint is dry, dismantle your scaffold, fold up the tarpaulin, and then stand back and admire your work!
