Preparing a surface for painting is important, but especially when it comes to wood.
You want a perfectly even color, with no streaks or visible spots from the layers beneath, even more so if you’re painting furniture that takes pride of place at home.
Failing to properly prime your wall, or using an inadequate primer that isn’t up to the job, could have dire consequences. Unfinished wood absorbs paint like a sponge, so you’ll end up buying way more cans than you would have otherwise to get it finished!
Hours of research later, we’re here with our list of the best paint primers for wood, however precious and important, so there’s no risk of damaging those family heirlooms.

Buyer’s Guide
Why Use Primer – What Are The Benefits?
Disguises Wood Grain And Knots
Some readers might like the imperfections (known as knots) that are visible in wood after branches have grown with imperfections; these knots are just what remains after a dead branch falls from the tree it was attached to.
Others, however, want to paint over wood – in a variety of colors and finishes – and priming ensures that these darker spots in the grain are completely covered up. Otherwise, they’ll be quite distinct, no matter how many coats of paint you put on!
Ensures Paint Will Bind
Working to create a much stronger base for applying a coat of paint to, a primer ensures that whichever finish you’re looking for, the paint will adhere to your wood much more easily, being incredibly sticky and all. Be careful not to spill it!
This is especially useful for wood in particular, as it is a naturally absorbent material and therefore tends to soak up a lot of paint if not primed beforehand. Porous surfaces take way more coats than average without proper priming!
Smooth Surface
Got wood that’s dirty or in poor condition and unable to be properly cleaned, or feels too dark to be painted smoothly? Primer can solve both of those problems, allowing you to use a light color and create a clean base for your paint to go on.
You’ll need fewer top coats overall, it will be way less likely that any dirt or staining bleeds through, and you can also get primers that are closer to the color that you want to paint on top. It’s a win-win situation!
Protect Wood Itself
As wood is not a naturally water-resistant material, primer actually has a dual benefit of sealing it away when exposed to the elements. Outside furniture that has been primed before painting, for instance, is less likely to form mold after heavy rain.
Plus, if you’re painting an especially old or valuable piece of wooden furniture, the primer serves as a barrier between it and the paint you’re using. That way, should you decide to remove it in the future with stripper, the wood beneath is safe!
Guarantee Durability
By filling up the pores of a surface, covering up any difficult marks and creating a layer that is desperate to bond with your paint, you’re ensuring a completely smooth color finish with no marring or annoying spots.
As well as this, you will also find that the finished paint job is far less likely to sustain damage or marking, nor will it peel in sun spots or fade after just a couple of seasons. For long-lasting paint, using a primer is fundamental.
Primers 101 – Which To Use When
Stain Concealment
So, you’ve had an unfortunate accident and need to cover up a stain on your wood with the help of paint. In this instance, you’re going to want a primer that’s dedicated to blocking or covering stains. This is usually indicated in the product description!
Does your stain involve grease, ink, crayon or another solvent-based material? Such a spill is going to need a water-based primer that’s also tinted, otherwise you’ll have less success at covering it up.
Unfinished or Bare Wood
Naked wood (get your mind out of the gutter!) is simply wood that is bare, so has never been touched with a stain or paint. In this situation, an oil-based primer is going to suit you best. This will create a nice thick layer to prevent paint absorption.
You could also go with latex-based primer, though without treating we’d highly recommend sticking to the oil formula, just because they’re better for preventing paint soaking through more porous wood.
Unfortunately, oil primers tend to require a lot longer to dry – though as a result, paint will stick better – so if you wanted to try a quicker drying water-based formula it certainly wouldn’t do any damage. But it will make sanding down trickier!
Pre-Painted Wood
Already painted this wooden furniture? You’ll absolutely want an oil-based primer in this case – they are able to penetrate through old layers of paint when you’re coating wood, which helps really cover up the previous color.
Likewise, if the existing paint has a chalky finish, a latex or water based primer isn’t going to cut it, especially if there’s cracking on the top coat. Oil-based is your best bet here, despite the lengthy curing time!
Composite Wood
If you’re looking to paint some old plywood, MDF or particle board, choose your primer according to your reason for painting: if you just want to weather-proof or create a decorative coat, then oil-based is a good bet.
In the case of MDF specifically, you’ll find that water based primer does not work at all, and you’ll also achieve pretty terrible results on plywood as well. It’s a thinner material, so the water is easily absorbed, which leads to warping of the wood.
Choosing A Primer – What Else Should You Think About?
First things first, assess your personal needs. Are you painting finished or unfinished wood? Is it already painted? Are there any knots or grains you want to cover? What kind of finish do you want for your end result?
Similarly, where is your painted wood going to live – indoors or outdoors? Will it be touched often or gazed at lovingly from afar? Ask yourself all of these questions and ensure that the primer you go for is suitable for your needs.
Here are two other important things to bear in mind:
Safety Considerations
Some primer formulas are found to contain significant amounts of what’s known as VOCs, or volatile organic compounds. Improper use could have fatal results as a result, should they be swallowed or come into contact with your eyes, face or skin.
As a result, it’s important to wear a respirator during the application of primer, paint or staining, especially if you’re using oil-based formulas, as these tend to have a higher concentration of VOCs. They might be uncomfy, but they keep you alive!
Likewise, you’re going to want to ensure all windows and doors are open, allowing proper ventilation and the circulation of fresh air. Otherwise, you could end up inhaling some seriously toxic fumes and headed to the ER!
Curing Period
Also known as “how long the primer takes to dry properly”, this time varies from formula to formula. Some promise to be bone dry in 30 minutes, whilst other manufacturers suggest a minimum of 48 hours for curing.
Latex primers dry faster than oil-based formulas when it comes to wood, so if your situation allows for it (following the guide above!) then consider using one of those for a faster process overall. Do remember though: slow and steady wins the race!
Perfect Priming Every Time – Quick Steps For Best Results
Get The Wood Ready
Preparing your wood for priming before you start is incredibly important. First things first, clean it up as best you can, being sure to remove any dirt, dust or other debris from the surface.
Next, it’s time for sanding – a finer, medium grit (around 200-200 grits would be great) is recommended. By working it all over you can ensure the surface is as smooth as possible, which makes priming easier overall and creates a better finish overall.
After sanding, there’s going to be a whole lot of wood dust, so go ahead and clean up the mess you’ve made, give it a quick wipe down with a slightly damp cloth and there you have it! All good to go.
Frequently Asked Questions
Do you have to prime wood before painting?
Nobody is going to show up and arrest you if you don’t, but especially when working with unfinished wood, a primer is going to make your life a whole lot easier in the long run. That might sound contradictory, given it’s an extra step to the process.
However, by using a primer, not only will your coats of paint be smoother, but it will require fewer coats overall because the primer works to fill up pores. Therefore, the paint is less likely to soak through, creating a nice seal for your paint to stick to.
Does a primer coat have to be perfect?
Not perfect, no! We’re not talking Stepford Wives here, but you do want to ensure that the entire surface of whatever you’re painting has been covered, with no obvious missed spots or bare patches.
Given that you’re priming your wood to be painted to create the best, most uniform coat possible, you want to try and give that the best possible shot. If there are no visible differences or obvious uneven bits, you should be good to go.
Does paint and primer in one really work?
It depends on what you’re painting! Also called self-priming paint, these formulas combine the painting and priming processes. However, if you’re painting something that has never been painted before, a separate primer is essential.
Similarly, if you’re going to be changing the finish of something wooden, for instance going from slick to glossy or flat to semi gloss, a natural standalone primer will also work better. Going over an oil-based formula with latex or acrylic also calls for a separate primer too.
Can a wood primer be tinted?
It’s definitely possible, especially if you’re changing the color of the wood dramatically by painting and want to give it a head start. Tinting wood primer to be closer to the color of your paint is certainly doable.
Do just make sure that the two formulas are safe to combine – a quick Google search of both products or their key ingredients should help you with that. You don’t want to conduct a science experiment instead of painting, after all!
