Painting your deck can completely transform the look and feel of your outdoor living space. With some preparation, high-quality supplies, and a bit of elbow grease, you can tackle this project yourself and save money compared to hiring a professional. This easy guide will walk you through all the steps for a DIY deck painting project.

Planning Your DIY Deck Painting Project

The key to a successful DIY deck painting project is proper planning and preparation. Rushing into the painting process without thinking through all the details can lead to a subpar finish or the need for rework. Follow this advance planning checklist before getting started:

Determine the Right Time to Paint

The best time to paint your deck is during dry, warm weather when temperatures remain above 50 degrees Fahrenheit during the day and overnight. Otherwise the paint may not adhere and cure properly.
Avoid painting in direct sunlight which can cause the deck paint to dry too fast and not adhere well. Work during cooler parts of the day like morning and late afternoon.
Don’t paint after morning dew or if rain is expected in the next 24 hours. Moisture will impact curing and adhesion.

Select the Correct Paint for Your Deck

Exterior latex deck paints provide good coverage and protection for most standard wood decking. Oil-based paints are more durable but require more safety precautions.
If repainting, check what type of paint is currently on your deck. You generally want to use the same water or oil-based variety for proper adhesion.
For pressure-treated lumber, a paint designed for this material is recommended to resist tannins from leaching through.

Buy Enough Paint for Full Coverage

Measure the square footage of your deck using length x width to determine how much paint you need. Most deck paints cover 350-400 sq ft per gallon with one coat.
Account for uneven wood surfaces, railings, and multiple coats when calculating how much paint to purchase. Always better to have extra than run out halfway!

Check Weather Conditions

Use a multi-day forecast from a reliable weather source to choose a block of days for your project when sunny, dry conditions are expected.
Work when daytime temperatures will remain above 50 degrees Fahrenheit and overnight lows stay above 35 degrees.
Avoid windy days that could blow debris into fresh paint or create an uneven coat.

Gather Essential Painting Supplies

Drop cloths – Canvas tarps to protect patio, plants, lawn from paint drips and spills
Paintbrushes – 4-6” angled sash brush for cutting in edges, roller covers for bulk painting
Paint roller and frame – Look for good quality nap thickness to apply deck paint smoothly
Paint tray and liners – To hold ample paint for your roller
Primer – Precoat bare wood with compatible oil or latex-based primer
Paint pole – Extends your reach on railings, walls, ceiling
Rags, paint thinner, scrub brushes – For spot cleanup and brush maintenance
Masking tape & plastic – Protect surfaces not being painted like house siding
Plastic bags – For wrapping wet rollers to pause painting
Stir sticks – Essential for mixing paint thoroughly before and during use

Prepping Your Deck for Painting

Proper prep work is 95% of the work on a deck painting project. Taking time to correctly prepare the deck surface will allow the new paint to adhere tightly and provide protection for years to come.

Clear Furniture, Decor and Debris from the Deck

Remove all objects from the deck area to allow full access to all surfaces during painting. This includes:

Outdoor furniture cushions, umbrella, lightweight chairs/tables
Planters, mats, decor items, toys
Grill cover, brooms, hoses, and other accessories
Accumulated dirt, leaves, pine needles and other debris

Use a leaf blower or vacuum to remove dirt from between boards, railings, and other crevices. Sweep thoroughly since you don’t want debris inadvertently sealed under the new paint.

Inspect Wood Condition and Make Repairs

Check for cracked, splintered, or rotten boards that require replacement before painting. Use a screwdriver to poke at suspect areas and test for softness. Mark areas needing repair.

Use an orbital sander with 80-100 grit sandpaper to smooth small splinters, cracked edges, or gray weathered wood fibers. Caulk small gaps between boards.

For more substantial dry rotted areas, the damaged wood needs to be cut out and replaced with new pressure-treated lumber secured with galvanized decking screws. Sand replacement boards flush when done.

Remove Existing Paint with Sanding or Stripping

If repainting a previously painted deck, you’ll need to thoroughly remove the old peeling paint down to the bare wood. There are two main methods:

Sanding uses an orbital sander or hand sanding blocks to scour off paint. This creates a lot of fine dust which much be controlled. Work incrementally with 60-80 grit paper until only bare wood remains.

Chemical stripping utilizes heavy duty paint remover formulas brushed on to soften the existing paint so it can be fully scraped off with a putty knife. Stripping minimizes airborne dust but extra safety precautions are needed when handling harsh chemicals.

Both techniques are time and labor intensive. Consider renting a power sander to speed the process if renovating a large deck.

Clean Surfaces with Wood Cleaner

Once all necessary repairs are complete and old paint removed, use a deck cleaning solution to prepare the bare wood for new paint.

Mix wood cleaner like Wolman DeckBrite with water as directed and apply generously across the entire deck using a garden sprayer. Let it sit 5-10 minutes.

Scrub thoroughly with a stiff bristle brush to lift dirt, mold, mildew and gray fibrous material out of the wood grain. Rinse cleaner off completely before wood dries.

Let the deck dry for 24-48 hours before applying primer or paint.

Apply Primer to Bare Wood

Priming ensures even staining, provides extra protection, and helps the finish coat of paint properly adhere to bare wood. Use the same oil or latex-based primer as the planned topcoat paint.

For oil-based systems, look for primers like KILZ Original that offer strong stain-blocking. For water-based paints, choose a primer like KILZ 2 Latex.

Apply primer to all surfaces using a pad applicator, roller or brush. Work it into the grain to seal the wood. Let primer dry fully before painting – generally 24 hours.

Priming before painting is highly recommended but can be skipped if desired to save time. The finish paint will still adhere ok, especially if using a bonding primer like Zinsser Bulls Eye 123.

Painting Your Deck

Now that all the prep work is complete, the painting process goes much faster thanks to your thorough planning and surface preparation. Follow these tips for applying the topcoat deck paint like a professional:

1. Cut-In Deck Edges with Paintbrush

Use a high-quality angled sash brush to neatly “cut-in” around the perimeter of the deck first. painting about 2-4 inches from edges and corners with steady brush strokes.

This allows you to apply the bulk of the paint with the roller without the risk of drips. Take time to paint cleanly around posts, railings, stairs, and trim.

Pour paint into a roller tray and replenish brush as needed to keep a wet edge. Use drop cloths to protect any adjacent surfaces from drips.

2. Roll On Paint in Sections

Once cut-in, use the roller cover to apply deck paint to the interior floor and railings in approximately 4×4 foot sections. Work systematically across the deck to maintain wet edges and prevent lap marks.

Load the roller with a moderate amount of paint to avoid drips. Roll back and forth to spread the paint evenly across each board with slight overlap between passes.

Move slowly enough to give paint time to adhere and not slide off the angled decking boards if working on sloped sections.

3. Maintain A Wet Edge

It’s crucial to maintain a “wet edge” as you paint to prevent lap marks, especially with stains. Each section should be coated end-to-end without letting paint dry in between.

Work in cooler temperatures to slow drying, and paint adjacent boards immediately so fresh paint blends into “wet” areas. Periodically roll back over partially dry sections to blend.

Use joint lines as natural stopping points between sections if taking a break. Wrap paint roller in plastic bag to keep wet.

4. Allow Proper Dry Time Between Coats

Refer to the manufacturer’s recommendations on dry time needed between paint coats. Most deck paint requires 6-12 hours of drying before applying another layer.

Oil-based paints take the longest to fully cure. Humid conditions will also lengthen the dry time needed.

Visually check that the first coat is fully dry and hardened before starting the next coat. Test thickness by gently pressing a finger into the paint surface.

5. Apply Second Coat Perpendicular to First

Applying two thin coats provides better protection than a single thick one. For the second coat, simply repeat the same process but work perpendicular to the first coat.

If initially painting side to side with the wood grain, do the second coat in the opposite front to back direction. This helps fill any voids missed on the first pass.

The second coat provides full, even coverage and seals the wood fully. Additional coats are not needed in most applications.

6. Inspect for Missed Areas

Inspect the entire deck surface once fully painted to check for any missed bare spots, thin areas that may need extra touch up, or drips that require smoothing.

Address these immediately while paint is workable so they blend seamlessly into surrounding areas. Allow paint to dry fully before heavy foot traffic.

Cleaning up After Painting

Don’t let your eagerness to enjoy a freshly painted deck allow you to cut corners when it comes to proper cleanup. Follow these steps once the painting job is complete:

Wipe up spills or drips immediately using rags before paint dries.
Clean brushes, rollers, and other tools with the appropriate thinner – paint thinner for oil-based or water for latex.
Properly bag and dispose of dirty rags, drop cloths, roller covers and anything else containing wet paint.
Reinstall any lighting fixtures, outlet covers, hardware or other items that were removed prior to painting.
Return deck furniture and accessories now that painting is complete.
Check surrounding areas for stray paint drips and wipe up as needed.
Allow proper cure times before placing heavy deck items to avoid damage.

With attention to preparation, painting technique, and clean up, you can achieve professional quality results on your DIY deck painting project while saving a great deal of money compared to outsourcing the task. Taking time to do it right will provide years of enduring protection and great looks!

Frequently Asked Questions About DIY Deck Painting

Painting your deck is an achievable DIY home improvement project. But it raises lots of questions for first-timers! Here are answers to homeowners’ most common queries about finishes, prep work, application tips, and more.

What type of paint should I use on my deck?

For wood decks, exterior latex deck paints provide good protection and traction. Oil-based paints are more durable but require more safety precautions when applying. Match new paint to existing paint already on your deck for best adhesion. Look for products designed specifically for decks.

How long does deck paint last?

On horizontal surfaces exposed to foot traffic and the elements, repainting is typically needed every 2-4 years. Factors like sun exposure, weather extremes in your climate, and quality of surface prep all impact durability. Higher quality deck paints provide longer-lasting protection.

Should I use a paint sprayer to paint my deck?

Paint sprayers allow a fast application, but don’t always penetrate wood grain as well as brushed or rolled paint. This can lead to premature peeling or blistering unless using very thin viscosity paints. Most homeowners have better success using paintbrushes and high-quality roller covers to work paint into the wood.

How long should I wait between paint coats on a deck?

Check the manufacturer’s recommendations, as dry time between coats varies by product. Most quality latex deck paints can be recoated after 4-6 hours. Oil-based paints take longer to cure – often requiring an overnight dry time of 12-24 hours before adding another coat.

What kind of paint primer should I use on my deck?

Use the same oil or latex-based paint primer as your planned finish paint to ensure compatibility. For oil paints, look for “stainblocking” primers that contain shellac, like KILZ Original. For water-based paints, KILZ 2 Latex is a good quality option.

Should I use a paint sprayer or roller to paint my deck?

Quality angled sash paintbrushes are key for cutting-in corners and edges neatly. Rollers allow fast application across deck boards. Use an extension pole to easily reach railings without climbing ladders. Sprayers are trickier for amateurs to use successfully.

How many coats of paint does a deck need?

Most quality deck paints provide full protection and coverage with two thin coats. Applying multiple heavy coats does not improve durability. Make sure the first coat is fully dry before adding the second. Additional coats are only needed to address any thin patches or missed areas.

How do I choose exterior paint colors for my deck?

Light, neutral colors are ideal because they reflect heat and show less dirt. Grays, beiges and wood-toned stains are good choices. Avoid dark colors which absorb heat. Coordinate your deck color with the color scheme of your home’s exterior.

What kind of paint should be used on pressure treated wood?

Look for exterior paints specifically made for use on pressure treated lumber. These are formulated to resist tannins leaching through. Otherwise prime with a stain-blocking primer before applying your topcoat paint.

When is the best time to paint a deck?

For ideal drying and adhesion, only paint in dry weather when daytime temperatures will remain above 50°F for at least 24 hours after application. Avoid painting in direct sunlight which can cause adhesion problems. Morning and afternoon are best.

Should I paint or stain my deck?

Paint provides a vibrant solid color and more protection for decking wood. Stain allows some natural wood grain to show through with muted color tones. Paint is a better choice if your existing deck surface is already painted, while stains work better over raw wood.

Now you’re equipped to tackle your deck painting project with confidence. For a professional quality result, be sure to properly prepare surfaces, use compatible paint products, and apply with care. Your freshly painted deck will enhance your outdoor living space for years to come. Let me know if you have any other deck painting questions!
