Wood filler is a useful tool for fixing holes, dents, and other imperfections in wood projects. It’s also the perfect way to prepare old furniture for painting.
But if you don’t know how to paint over wood filler properly, your project could turn out to look like patchwork instead of a finely-crafted piece.
Can you paint wood filler?
This is a very common question, and since it’s so easy to find the answer, I’m not going to spend too much time explaining the basics of paint.
Put simply: you can’t! Or rather, if you do, it will be a waste of time and effort. Wood filler does not hold paint in any way shape or form.
If you try to paint over wood filler with new paint (or even touch-up existing painted woodwork), all that’ll happen is that your new coat of paint will crack like drywall plastering behind wallpaper (I’ve done this).
The good news is that there are ways around this issue without having to sand down those unsightly cracks created by the old filler job.
You may have noticed that most DIY websites recommend using a primer before painting over their products; well primer acts as an adhesive for whatever comes next—in this case, it’s another coat of topcoat (paint).
This means two things: 1) No matter how thickly you apply it onto bare woodwork, primer won’t crack because its main purpose isn’t sticking surface areas together but rather transferring them onto each other; 2) When applied correctly using an appropriate brush/roller technique (i.e., thin coats instead of thick globs), after 24 hours drying time no further preparation should be required before applying topcoat paints.

Can I paint straight over filler?
Yes, you can paint over wood filler. You don’t need to prime over it, and you don’t even need to sand the surface before painting.
But if your project is large or messy, it might be wise to use a roller instead of a brush for application.
The only thing that really matters is whether the filler is compatible with latex or oil-based paint. If so, then go ahead and use either one!
How long after wood filler can you paint?
The answer to this question depends on how long it takes for the wood filler to dry. If you paint over wood filler that’s not completely dry, the paint may peel off the surface of your project.
However, the longer a coat of paint sits on top of an existing layer—even if that layer is wood filler—the more likely it will chip or scratch off when you touch it.
This means it’s always best to wait until a coat is completely dry before applying another one.
Here are some tips for making sure your project is ready for painting:
- Wait at least one day after sanding before applying any coats of finish (like primer or sealer). This ensures that all dust has been cleared away and any contaminants have been removed from the surface; otherwise they could get trapped under subsequent coats and cause peeling later on down the road.
- Wait at least three full days between each application while using oil-based paint products; oils take much longer than latex paints do! If you’re using water-based latex products instead then wait 24 hours between applications so they can cure properly without affecting each other too much…
Can you paint over DAP wood filler?
Yes, you can paint over wood filler. Wood filler is essentially a smoothing compound that is applied after the wood has been cut or sanded.
It fills in any small holes and irregularities, so when you apply the finish like varnish or paint, it goes on smooth without any bumps or dips in the surface.
You can also use Dap brand for any brand of filler as long as it’s dry and hard to the touch (meaning don’t try to paint over wet fillers).
What wood filler can be painted?
If you are using a wood filler that has been oil-based, then you will need to sand and prime it before painting. Oil-based fillers are harder to use than water-based ones, but they also go on smoother and dry faster.
Oil-based products are made with linseed oil or tung oil as the base, so they’re more resistant to water damage if they get wet.
Do you need to prime filler before painting?
In this case, it’s not necessary to prime filler before painting. However, you should always consider priming your wood filler when it’s going to be exposed to moisture or if you plan on painting over a darker color.
Primer is a good idea if you have cracks in the wood and/or stains that may bleed through the paint. Primer also helps fill in small holes and imperfections in the wood, which means that your finished project will look much nicer than if you didn’t use any primer at all!

How do you paint over filler?
You can paint over wood filler. However, it’s important to know that if you don’t use a primer before painting, the filler will show through and look like a patchy mess.
It’s always best to use paint that matches the existing color of your wall or piece of furniture.
To apply your paint smoothly and evenly over wood filler, use a brush or roller—and if you have access to one, consider using an airless sprayer for even faster coverage.
Do you have to prime over filler?
Painting over wood filler is possible, but it’s not as simple as just applying your chosen paint to the surface. You’ll need to sand down the filler first and then apply a coat of primer before you can paint over it using a roller or brush.
Once you’ve primed the surface, you’re ready to apply another coat of either latex or oil-based paint—it’s recommended that you use different types in order to avoid mixing them together accidentally.
The key thing here is to make sure that all surfaces are completely dry before applying any more coats of color! This can take up to 24 hours if you’re working with very large pieces like furniture or cabinets.
In summary, you can paint over wood filler. It is possible to do this without priming or undercoating and there are many advantages to painting over filler instead of just applying a new coat of paint.
However, if your goal is to completely hide the filler then you will need to prime it first before covering it with your final coat.
