Painting a deck is a good way to breathe new life into a deck. Over time, the weather will turn any vibrant wood deck into a lackluster scrap pile. Following the right deck painting process can give you an outdoor space you’re excited about.
I’m often asked about the deck painting process — so in this post, I’m going to cover everything from wood preparation to applying your final coat.
Deck Painting – Better than Staining?
Before we get into the nitty-gritty, let’s quickly talk about something homeowners often want to know: should I stain or paint my deck?
When you paint your deck, you get a finish that covers imperfections while adding some level of moisture and UV protection. Painting your deck is an excellent choice when the surface shows signs of aging and damage you want to cover up.
Deck paint can last for up to ten years, but you’ve got to get high-quality deck paint to avoid chipping and other issues. With a stain, you’re looking at needing to reapply every couple of years. Paint is also easier to maintain. Why? It’s a slick surface that you can easily sweep and keep clean. Stain is matted and harder to get off dirt and debris. Stain, though, is easier to apply and blends in more naturally with the wood.
You can also paint on top of the stain — lots to think about. But let’s assume you’re committed to pain and hop in on the prep work. Here are the steps to take from start to finish:
1. Gather your tools and clean your deck
From the moment your deck is exposed to the elements, it will need to be cleaned if you paint. It doesn’t matter if it was just installed. You’ll want to clear it of any debris, dirt or pollen.
Make sure you’ve got everything you need: deck cleaners, a garden hose dispenser, mildewcide, a nylon bristle brush, and a brightener. A good, all-purpose deck cleaner removes all the problem spots on your deck. Using a garden hose dispenser, you can spray the cleaner to get rid of dirt, grime, and debris easily. If your deck has mold and mildew, pick a cleaner that can give them the boot, too.
It goes without saying, but take everything off your deck, including furniture, rugs, and plants, so nothing obstructs your workspace. Then, sweep off loose dirt and debris.
I’d skip the power washer unless you’re hiring a pro or know how to work one well. They are powerful tools, sometimes too powerful. It can carve chunks out of wood if improperly used. Once you’ve applied the solution, use the bristle brush to scrub the deck. Cap off your work by washing the deck with a garden hose (preferably with a jet nozzle).
Allow your deck to dry completely after cleaning. Allow 24 to 48 hours for your deck to dry fully, although weather conditions will affect the drying time. Avoid painting wood that hasn’t dried fully because it will inevitably lead to paint peeling and bubbling.
Here are some other tools and tasks you’ll need for later steps:
Wire brush: Lightly sweep over areas where you need to remove loose deck paint or chipped pieces.
Sander: Smooth rough areas with sanding tools such as an orbital sander or sanding block.
Wood Filler: Use wood filler to repair cracks or holes found in deck boards.
Painter’s tape: There are probably areas you need to make sure you don’t accidentally get pain on.
2: Check the Weather
Painting a deck requires ample drying time because rushing can cause big issues. Uncooperative weather can ruin your deck paint job.
Deck painting works best on dry days with mild temperatures from 50°F to 85°F. If you can, avoid painting when direct sunlight is hitting your deck because fast-drying paint can result in uneven layers and visible brush strokes. Check the humidity levels, too.
Hold off on painting if you see rain or high humidity in the forecast. Avoid painting wood that hasn’t dried fully because it will inevitably lead to paint peeling and bubbling.
3: Sand and Repair Any Damage
Sanding will solve problems with your deck’s rough surfaces, peeling paint, and splintered boards on your deck. Clean rough areas and eliminate loose or peeling old paint using an orbital sander with 80- to 120-grit sandpaper. High-traffic areas require particular focus because they are the places where peeling typically happens first.
Inspect the wood carefully for any visible cracks or holes and areas that feel soft. After locating any damage, fill it with exterior wood filler before allowing it to dry and sand until it matches the level of the surrounding wood.
After sanding, completely sweep or vacuum to remove dust before wiping the deck down with a damp cloth.
4: Apply a Primer (If Needed)
If you’re working with bare wood, need to cover a wood stain, or making a drastic color change, a primer is something you’ll want to add in. First, if you’re painting over previous deck painting, you need to know whether the pain was oil- or water-based. You’ll want to use the same type of paint.
If needed, you can find a primer that helps you transition from one to the other. You can also get a paint and primer combo to make the process easier. Apply primer to edges and corners with a brush before rolling it onto the larger deck boards. Wait four to six hours for the primer to dry before painting.
5: Paint Your Deck
A deck painting post should talk about painting. So, here we go. Begin painting using a brush to cut in around railings and edges and access difficult spots. After cutting in the edges, use a paint roller with a 3/8-inch nap to cover the larger sections by painting long, uniform strokes that follow the wood’s grain.
Two thin layers of paint will provide better coverage than one thick application. This ensures a more even, durable finish. After applying the first coat of paint, make sure it fully dries before adding the second coat, which takes four to six hours for drying time — exact times vary by paint, so check the manufacturer’s instructions.
Keep in mind that paint can take 7 to 14 days to cure completely. Be gentle in this window. Dragging furniture or heavy objects on the deck surface is not a good idea.
Once all work is done, sweep, clean, and paint over stains when needed to keep the deck in top shape.
Quick Summary
Deck painting requires significant DIY effort but delivers exceptional results, transforming your outdoor space once completed. If you dedicate time to preparing and applying paint evenly followed by full drying, your deck will maintain a stunning appearance while enduring weather conditions for many years.
