I’m going to show you how to use Bondo wood filler, one of the most useful tools in any DIYer’s toolbox. Bondo is a glue-based compound that makes it easy to fix dings, cracks, and other issues with your wood. It’s not just for professionals: anyone can use it!
Step 1: Preparing the Area
- Clean and sand the area to be filled. Remove any loose paint or varnish, and cut off any loose edges.
- If necessary, apply a filler primer first to ensure proper adhesion of the Bondo wood filler. This step is optional if you are using a color that matches your original finish.
- Cover the area with plastic and tape it down so it does not move while you work on filling in the defects with Bondo wood filler.
- Use an old damp cloth to wipe off any dust from your freshly sanded surface before applying Bondo wood filler

Step 2: Sanding the Wood
Now that you’ve applied the Bondo, it’s time to sand the wood.
Sanding is one of those tasks that can be super tedious and annoying, but it’s important! Sanding removes any rough patches and gives your project a nice polished finish.
- Using medium grit sandpaper (around 80-100), use circular motions with a sanding block or hand sander to smooth out any rough spots in your Bondo. If you’re using a hand sander, make sure not to apply too much pressure on the surface; this could damage it further. You can also just use a paintbrush if you don’t have access to tools like these!
- After you’ve sanded down your project, wipe away all of the dust particles using either a vacuum cleaner or an old rag damped in water—both will work just fine for this step!
Step 3: Applying the Filler
Now that you have a clean, dry area to work with, it’s time to apply the filler. Use your putty knife for this step. Make sure you’re working in an area where the fumes won’t bother anyone—it might be best to do this project outside or in a garage with the door open.
First, scoop out some of your wood filler with your putty knife and set it onto your surface (in this case, we will keep using our sandpaper). Then use your putty knife to spread it evenly over the area where you want to repair (you want it thin so that there’s no white showing through). Once it’s applied evenly across all areas of damage (and they should be completely covered), let them dry overnight before sanding them down again tomorrow morning!
Step 4: Finishing the Application
Once you’ve spread the filler, it’s time to smooth it out and make sure that the surface is nice and even. To do this, use one of these tools:
- Paint roller
- Putty knife (or other small flat edges)
Step 5: Adding Stain to the Bondo
Now, you can apply the stain. Use a brush to spread it over the area that has been filled. The color should be even and cover all of the filler. Once you’re satisfied with how it looks, let it dry for at least 24 hours.
After it’s dry, go ahead and sand down any rough spots or bumps that were caused by applying too much filler (or not enough). You can do this with medium grit sandpaper—generally, 80 to 120 grit is fine—and then move on to applying one more coat of primer before doing any painting.
Step 6 : Using Primer on Bondo
Let’s start with the primer. Primer is a must when using Bondo over wood, and it will help to ensure that your filler will properly adhere to (and be painted over) whatever surface you’re working on.
You can buy a variety of primers designed for use on different materials (such as metal, plastic, or wood), but keep in mind that whatever product you choose should be able to withstand the heat from your paint gun.
If you’re painting directly over bare wood, then pick up some type of acrylic primer specifically made for use on bare wood surfaces; if there is already paint present on your project then try using an epoxy-based waterborne finish—it’ll form an extremely tough bond between layers!
Step 7: Painting Over Bondo
You can use regular paint to cover the Bondo. Just be aware that while it will cover the filler, it will not help with any small cracks or raised areas in your wall that were not filled completely by the Bondo. If you want to do this, we recommend using a primer first so that your wall doesn’t absorb too much of the paint and flake off later on. We also recommend using a brush or roller as opposed to spraying because it gives you more control over how thickly you apply the paint and lessens the risk of creating drips or runs.
Step 8: Considering Other Options
Once you’ve decided that Bondo is the best option for your project, there are a few other considerations to take into account.
There are two main types of filler: soft and hard. Soft fillers are good for filling large holes or voids in wood, but they’re not ideal for repairs like cracks and dents because they don’t hold their shape very well. Hard fillers have a higher density and can be applied more thinly than soft fillers so they’re great for repairing dings and small cracks in wood surfaces.
The type of filler you choose will affect how it holds up over time as well as its application process:
- Soft fillers can be used on wet surfaces (such as if you’re working with an existing finish) or dry ones without adhesion issues because the solvents in these products help bond with the surface below. However, because these solvents evaporate quickly after application, they won’t stick well after drying out so this type of product needs frequent reapplication throughout its lifetime—and may need replacement altogether once it’s been used up completely! In contrast…
You can use Bondo wood filler to fix some small issues in your wood.
If you want to fill the holes, scratches, and dents in your wooden furniture or boat, Bondo wood filler is one of the best options for you. Bondo is a polyester resin that is used as a two-part epoxy resin and hardener. It has very strong properties that make it ideal for filling holes in wood. It dries quickly and gives excellent results by blending into your existing surface perfectly without leaving any trace behind.
It’s also important to note that even if you use this product correctly, it will still not look exactly like the original wood because it doesn’t have the same texture as real wood.
