Scrape off any big flaky pieces with a scraper or a putty knife, these flakes will just get in the way when you're trying to sand.
When all of the big flakes have been removed, use a palm sander or a sanding block to rough up the surface of the existing paint.
You don't need to remove all of the old paint if you're repainting. you just want it to be a nice smooth surface for the new paint to adhere to.
Fill any gouges or nicks with wood filler and let it dry completely. Once it's dry, sand the surface of the filler so it's even with the surrounding wood.
Wipe down the entire piece with a tack cloth to remove paint and wood dust.
Now you're ready to re-paint. I recommend using a bonding primer on previously painted wood to be sure you'll get a good seal. Use a small foam roller for a speedy application on flat areas!
Once the primer dries, we'll be ready for our top coat! Easy repainting steps! I'm Mrs. Fixit and it's just that simple.
