If you have a piece of stained wood furniture that could do with a new lease of life, you might be wondering whether you can paint over it.
You can certainly paint over stained wood, however, there are a few things you need to do beforehand to ensure that the paint adheres to the surface and that it goes on smoothly.
This process will depend on the type of stain you use, the current condition of the wood, and whether or not the piece you’re painting is furniture.
We’ll be covering all of the most frequently asked questions regarding painting over stained wood, so you know the best steps to take in order to get the results you want.
Can I paint over stained wood without sanding?
Technically you can do this, but you need to prepare the surface in a different way, and the best way to do this would be by coating the stained wood with an oil-based primer to prepare it for new paint.
The oil-based primer will stick to varnished or sealed wood, and then you can apply your paint – a latex one will work best.
However, sanding your piece is the usual course of action for stained wood. Ideally, you want to sand down the stained wood surface with 150 grit sandpaper. This will make the surface just about rough enough for the paint to grip onto it. However, there’s no need to strip the entire surface, although some people may choose to do so.
Can you paint a design on stained wood?
There’s nothing stopping you from painting a design on stained wood, so long as you use the correct primer and paint for the type of stain that was applied to your piece.
Do you need to prime stained wood before painting?
Yes, you pretty much always need to prime stained wood before painting. Priming provides a smooth surface for the paint and gives it something to adhere to.
However, the type of stain that’s been applied to the furniture piece will determine what type of primer you need to use.
Priming water-based stain
If you’re painting over a water-based stain, you should use latex primer and paint, which can be applied with a brush or a roller.
Paint usually adheres pretty well over water-based stain, but for the best results, you could ask your paint supplier or store to tint the primer a similar color to your topcoat.
Follow the manufacturer’s instructions, but the general rule of thumb is one coat of primer and two coats of latex paint for complete coverage.
Always give sufficient time for each coat to dry before applying the next – ideally overnight if possible.
Painting over oil-based stain
If you’re painting over oil-based stain, you’ll need to take a slightly different approach, as oil-based stains require a little more prep.
It’s possible to paint over the stain with either latex paint or oil-based paint, but you’ll need to prep the surface first.
Safety goggles and gloves are essential for this bit, and ideally, you should turn on a fan to circulate the air.
You’ll need to dissolve a quarter-cup of trisodium phosphate (TSP) in one gallon of warm water, then dip a soft sponge into the mixture, wring it out, and wipe down the surface, removing all traces of dirt and grime. Repeat this process and give the surface some time to air dry.
Next, you’ll need to sand all the rough areas and wipe them clean with a damp rag to remove dust and residue.
You can then apply a bonding primer to the dry, sanded surface. Choose a water-based formula designed to adhere to glossy and other hard-to-paint surfaces (such as varnish and polyurethane), and be sure to follow the manufacturer’s instructions.
Once your primer is dry, you can then move on to applying two coats of paint. Don’t forget, use interior paint for indoor projects, and exterior for outdoor applications.
What is the best way to paint over stained wood?
As we said previously, you’ll need to use the right products for the type of stain that’s applied to your wood, but there are some general steps that will apply to most projects.
Step 1: Sand the wood
You should sand down your stained wood with 150 grit sandpaper for best results.
Step 2: Clean the wood
After sanding, grab a tack cloth to wipe down the piece and remove any remaining dust particles.
Step 3: Add a coat of primer
Apply your primer with a foam brush or foam roller to get the best results.
Step 4: Wipe down the wood
Once your primer is dry, take a new tack cloth and give the wood a wipe down again to ensure it is fully dry and clean.
Step 5: Paint your wood
Once your primer coat is dry, grab a fresh foam roller and apply at least three coats of either latex or oil-based paint.
Latex paint will work best for cabinets and doors, while oil-based paint is great for high-traffic areas like decks and porches as it’s more durable and offers maximum protection.
Allow sufficient drying time – ideally six hours – between coats. You can use the drying time to inspect the wood for any clumped leftover paint residue that can be removed with a tack cloth before the paint has thoroughly dried.
Step 6: Apply the finish
Once your paint is dry, you can then apply your finish.
The best option is to use a Polycrylic Protective Finish. This usually comes in a spray or wax form and can be applied using an aerosol or cloth, depending on the manufacturer’s recommendations.
What kind of paint do you use on stained wood?
For stained wood, you can use water-based latex paint, or oil-based paint – the choice is yours.
Oil-based paint offers excellent protection and durability, while water-based latex paint is easier to apply and won’t leave a strong odor.
