When you’re woodworking, it’s important to use wood filler before sanding. Wood filler helps to fill in any gaps or cracks in the wood, which makes the surface smoother and easier to sand. It also helps to create a more uniform finish. In this blog post, we’ll discuss when and how to use wood filler before sanding. We’ll also provide some tips for getting the best results!
Do You Use Wood Filler Before Or After Sanding?
You should use wood filler before sanding if you want a smooth surface. Wood filler is a putty-like material that is used to fill in small gaps and cracks in wood. It can be sanded down once it dries, which will create a smooth surface. Wood filler can be used for a variety of situations, such as filling in gaps between boards on your deck or even repairing cracks in furniture that have been exposed to water damage.
It’s important to know how much wood filler you need before applying it because too little might not fill up all the holes and cracks properly while too much can make the surface uneven. Make sure to read the instructions on the wood filler container before using it. Wood filler is available at most home improvement stores.
Do You Use Wood Putty Before Sanding?
Wood Putty should be used before you sand. Wood filler is usually applied to the wood and then allowed time to dry. Once it dries, wood putty can be smoothed down by sanding. Using a piece of fine grit sandpaper will help smooth out any imperfections in the wood that may have been left after using your wood filler.

How Long Does Filler Take To Dry Before Sanding?
Wood filler takes between one and three hours to dry before sanding. It depends upon the type of wood filler you use, your climate and how thick the application is.
Filler takes longer to dry in a humid environment and when applied thicker than recommended. When the wood filler has dried completely it will appear darker compared to wet wood filler.
After the filler has dried, it is sanded with fine-grit sandpaper. The goal is to make the surface smooth so that you will have a good base for painting or staining.
If you are using wood putty, then wait overnight for it to dry before continuing. Putty takes much longer than wood filler to dry because it is a more dense product.
The final step is to apply a sealant or topcoat to the surface of the wood. This will protect it from moisture and fading. Make sure that you allow the sealant or topcoat to dry completely before using your furniture or project.
Wood filler can be used on many different types of wood projects. It is a good way to cover up defects and inconsistencies in the wood surface.
If you are not sure whether to use wood filler before or after sanding, then test it out on a small piece of scrap lumber. This will give you an idea of how the filler will look and how much sanding will be required.
How Do You Apply Wood Filler?
Wood filler is applied by using a putty knife or plastic spreader.
Apply the filler to smooth, sanded wood so that it can adhere well and level out without bubbling.
Can I Use Wood Filler After Primer?
You can use wood filler after priming if you don’t mind a thicker coat of primer. Wood fillers are more difficult to sand than regular wood so too much can really affect your paint job.
You should wait until the primer is completely dry before applying wood filler, as it will not adhere well otherwise. If you need to use water-based wood filler on top of oil-based primer, you may have to sand before applying the next coat (see below).
You can use water or oil based wood fillers. Water based is easier to clean up and dries faster but often has a higher shrinkage rate. Oil based wood fillers will dry more slowly and can be sanded easier but may not adhere well to water-based primers.

Can You Sand Wood Filler?
You can sand wood filler, but you have to be careful not to sand through it. If you’re using a very fine grit sandpaper, you might be able to get away with sanding the wood filler without damaging the surface of the wood underneath. However, if you’re using a coarser grit sandpaper, you’ll definitely need to take care not to sand through the wood filler and expose the surface of the wood underneath.
If you’re sanding a piece of furniture that already has a stain on it, be sure to use finer grits only (such as 220 or 400), so that you don’t remove too much finish from your project before applying new stain to it. If there are any areas where the wood filler is not completely smooth and level with the surface of your project, you will want to sand them down until they’re even before applying stain.
If you are sanding a piece of furniture that has paint on it, be sure to use finer grits only (such as 220 or 400), so that you don’t remove too much paint from your project before applying new paint to it. If there are any areas where the wood filler is not completely smooth and level with the surface of your project, you will want to sand them down until they’re even before applying paint over top of those spots.
In addition, if you’re using a wood filler that contains wax or oil, such as Minwax Wood Filler, it can be sanded down easily with fine grit sandpaper (such as 220 or 400) before applying stain and/or paint over top of the wood filler.
Does Wood Filler Need To Be Sealed?
Yes, wood filler needs to be sealed. You should wait until the wood filler is completely dry before you sand or seal it.
If you do not, your work will be ruined and you will have to start over again.
Make sure you use the right type of sealant for your project.
Should You Prime Bare Wood Before Filling?
A lot of woodworkers will tell you not to prime bare wood before filling because they think it makes sanding harder or more difficult than necessary.
First, if you are using an oil-based filler, then it’s definitely important to prime the wood first. This is because the oil in the filler can cause the primer to not stick properly. If you don’t prime the wood, then you may find yourself having to sand through multiple layers of paint (or whatever else you’re using) before getting any success with your woodworking project.
Second, if you are using a water-based filler, then there is no need for priming at all because the water will soak into the wood and provide enough moisture content to allow the filler to adhere properly.
Can I Put Wood Filler Over Paint?
Yes, wood filler can be used over paint or varnish. The primer will help it adhere to the surface of your project. And if you use sandpaper and a block to smooth out any rough spots before applying the putty, there shouldn’t be an issue with adhesion either way!
When you’re ready to sand off excess wood filler from the surface of your project, it’s best not too overdue this step so that you don’t create any grooves in which dust will settle later on (especially if there is still paint left on top).
If you have a lot of wood filler or other products like spackle on your project, it’s always a good idea to give the entire surface a light sanding before you start painting or applying any other finish. This will help everything adhere better and look nicer in the end. Now get out there and start filling some holes!
