In this video, painter Mauro Henrique paints an outdoor railing that Nathan just built to match the original railing around a homeowner’s deck.
Steps for Painting Exterior Railings
- Use painter’s tape to protect the deck and the older railing.
- Put a dropcloth down to catch any debris, primer, or paint.
- Use 180-grit sandpaper to sand down any imperfections in the wood. Mauro used a sanding block for the balusters and a random orbital sander for the posts and railings to get the job done quicker on the larger areas.
a. Wear a mask and gloves to protect yourself from splinters.
- Vacuum all the debris.
- Start priming. Use a mini roller for the larger areas and a paintbrush for the areas that are harder to get to.
- Focus on the bottom wood, that’s where most of the water will end up.
- Let the primer dry before painting, wait about an hour.
- Fill in any nail holes with exterior-grade wood filler.
- Let the first coat dry and add the second coat.
Mauro wanted to match the paint color of the existing deck, which he did by bringing a small sample of the existing paint to a local paint store. Most paint stores and home centers have machines that can scan a sample and generate a close color match to the paint.
The paint Mauro used for the railings was Behr Premium Plus Exterior Semi-Gloss paint and primer, though he also used a separate, oil-based primer for the base coat.
