How to Repaint a Deck with Peeling Paint

Repainting a deck with peeling paint may appear intimidating, but the finished product is highly satisfying when done right. First, remove the flaking paint and then repaint it with a new coat.

Step 1: Power Wash The Deck Thoroughly

To eliminate dirt on the surface and grime trapped between deck boards, mold, and mildew, washing is necessary.

Pressure wash the flaking paint off the surface. Use a rotating nozzle for your pressure washer and angle the washer wand to prevent the pressure from gouging the wood. Use sweeping motions and maintain a six to twelve-inch distance away from the surface.

Where necessary, use an all-purpose deck cleaner and scrub with a stiff brush to remove any build-up debris. If you notice any mold or mildew on your deck, use a cleaning solution containing mildewcide.

Rinse your cleaned deck and let it dry for 48 hours or more if necessary.

Step 2: Scrape The Loose Paint

Remove more flaking paint using scraping tools. Use a wire brush in light sweeping strokes over the shedding paint to lift it off the floorboards.

If no more paint comes off by brushing, scrape them using a paint scraper or putty knife. Sink the sharp and flat scraping tool slightly below the paint and push it to peel it off the surface.

Unfortunately, this method is only practical for small spots of peeling paint.

Step 3: Sand the deck

Is the peeling paint consistent over a large area on your deck? In which case, powered tools make more sense.

Use a power sander to speed up the paint removal process. The advantage is you can buy or rent it for your projects at a nearby rental unit.

Use sandpapers (60-100 grit) on your deck and lightly sand along the wood grain. Replace the sandpapers when they get clogged, or the grits fade. Sand the surface evenly, but not too much to thin the wooden floorboards.

Wash the deck once again with a garden hose to remove every sanding dust from your deck. After that, allow your deck to sit for another day or two to dry before painting.

Step 4: Prime and Paint 

Prime your deck using a high adhesive primer like KILZ Adhesion High-Bonding Interior and Exterior Primer. Apply two to three layers of the primer, making sure to coat the surface evenly. Wait for an hour or two between each coat of primer.

Still, some paints contain both primers and paint in one can. So if that’s the paint you choose, you won’t need a separate deck primer. However, ensure the paint is specifically designed to be used on exterior horizontal surfaces.

Now, get ready for the deck painting process. You will need either a paint roller, paintbrush, and or deck paint sprayer.

Use a roller with an extension pole to apply the paint evenly and comfortably. Use a crack and groove brush to apply paint between the floorboards too. Otherwise, your work will appear incomplete.

Or, spray paint your entire deck. This method is faster and gets the paint in areas where a regular brush or roller wouldn’t. Make sure to back roll or back brush the spray paint evenly on the deck boards.

Step 5: Finishing details

Once the first paint coat has dried, apply the second one using the same tool you used for the first one. Again, let this coat sit undisturbed for the recommended time, and add a day or two more before using your deck once again.

After that, schedule regular maintenance practices to keep it in tiptop shape.

Can You Paint Over Peeling Paint? 

Yes, you can paint over peeling paint. However, whether you should repaint or repair the peeling deck depends on the amount of damage that exists.

First, scrape and lift the flaking paint using a putty knife or a wire brush. Next, scuff sand the entire surface, then wash the dust and debris off. Prime the bare spots and paint a fresh coat to your old deck.

How To Repaint A Deck Without Stripping

Painting over peeling paint on wood is possible because the existing paint or the damaged areas are small and won’t show through the new paint coat.

The Steps 

Step 1: Assess the failing deck paint

Determine the extent of the damaged old deck paint. Then, start scraping the loose paint using the right tools: a putty knife, paint scraper, or a wire brush. Countersink nails and loose wood sticking up. Fill any cracks with wood filler.

Step 2: Sand

A little scuff sanding on the edges of the bare wood and the areas where paint is still intact is necessary.

Step 3: Clean the entire deck

Use a garden hose and allow it enough time to dry: a few hours or overnight depending on the humidity levels in your region.

Step 4: Prime the bare wood spots

Use the respective primer –water-based or oil-based –to the existing paint on the deck and the new one you plan to apply.

Step 5: Paint over your entire deck

Use a paint roller or sprayer to paint over a larger area in half the time. Alternatively, you can use a paintbrush if you don’t mind brush strokes.

Step 6: Let the first paint coat dry to the touch before applying the second coat.

This will ensure your paint layers stay intact for a good number of years.

Allow the deck to sit undisturbed for two days after the last paint coat. After that, you can go on and enjoy your newly painted deck space. 

Why Does Deck Paint Peel Off Wood?

There’re some common reasons why your deck would be peeling. Take a look below.

Poor Surface Preparation

Surface preparation for a painting involves thorough washing, sanding, priming, and eventually, the painting itself. If you do a sloppy job at any stage or skip any of these steps, your deck paint job will come off sooner than you’d like.

Low Paint Quality

Inferior paint quality will fail as soon as it’s exposed to the elements. Bad news awaits you if you fall for advertisements claiming any exterior house paint will work for your deck.

Poor Painting Method

The painting technique can make or destroy your deck paint. The first coat should be light and even for it to properly adhere to the wood. The paint also needs time to dry thoroughly before applying the subsequent coats.

High Moisture Content

If the deck wood was painted while wet, the paint will flake and fall off. Alternatively, if there’s excessive exposure to external moisture, most new deck paint won’t hold up for long.

How To Stop Paint From Peeling On Wood

Stop wood paint from peeling by preventing the factors that trigger the paint failure.

Start by preparing your wood religiously: Wash, sand, prime, and paint. Throughout this process, ensure there’s sufficient drying time between each step.

Stop moisture from softening and lifting your deck paint by painting bone-dry wood and eliminating the external source of dampness. For example, redirect garden sprinklers, repair leaking roof gutters and kitchen or bathroom pipes.

You can also trim nearby vegetation and waterproof the surface beneath your deck if you think it’s a source of moisture ruining your deck.

It also helps a ton if you choose and use a high-quality outdoor deck paint explicitly designed to be used on deck boards. Consult your paint dealer at the hardware store or read the paint can carefully before making a purchase.

Often, the manufacturer recommends the best tool you can use to apply the paint to your deck boards. Whichever tool you decide to use, you can paint the spaces of the deck boards and every section that’s hard-to-reach.                                                                                             

When Should You Repaint A Deck?

According to the recommendation by Consumer Reports, the best time to repaint a deck is during late spring. Usually, the temperatures at this time are between 60 and 85°F, and the nights are cool.

This is because you typically need four dry days to cater for preparation, application, and finish to dry fully.

Also, you should repaint as soon as your deck shows signs of failing, especially in high traffic areas.

If the original paint no longer protects the wood beneath. Or when the paint is severely blistered and is peeling on large sections of the deck. You could also repaint it when you want to update the dull color of your deck.

FAQs

Why is my wood porch paint peeling off?

Porch paint could peel off due to prolonged exposure to sunshine and moisture. These conditions make the porch wood expand and contract, triggering the paint to blister and peel. Still, the cause could be poor surface preparation done before painting. As a result, the paint can’t adhere to a damp or dirty surface.

Why is deck paint peeling after one year? 

One of the reasons your deck paint keeps peeling is poor preparation –either the wood deck wasn’t properly cleaned and sanded, or the paint was applied before the wood dried completely. Another possible reason is low paint quality used or paints applied too thickly without enough drying time between each coat. 

Do I need to remove old paint before painting deck?

No, you don’t need to remove old paint before painting a deck. You only need to remove old paint if it fails: blistering, cracking, or peeling paint before repainting. Otherwise, the new layer will bubble and peel soon after. If the old paint is still in good shape, paint over it.

Is it better to paint or stain a deck? 

The debate on stain versus paint narrows down to personal preference.  Staining a deck takes less time than painting, and it enhances the natural wood grain. Painting conceals cracks and any imperfection while providing a pop of color to complement your surroundings. Yet, both deck paint and deck stain protect the wood from damage by elements. 

What kind of paint do you use on a wood deck? 

Use oil-based or water-based exterior deck paints. Before settling on any paint, ensure it’s meant to be used on flat or horizontal deck surfaces. Note that any exterior paint on your deck might lead to it blistering and flaking off the surface prematurely.
