Make a Mold for the Repair

First thing’s first, before we jump into repairing that wood trim, make sure the damaged surface is prepped. Lightly sand it with 220 grit sandpaper, creating a rough surface for the Bondo to cling onto.

The next step is making a mold of the repair, if it has deep damage or a major break. If the damage is just some teeth marks, you can skip this part.

If you’ve got a similar undamaged part, it’s the perfect candidate. Apply a little Vaseline to it, then create the mold using hot glue or amazing mold putty.

Once your mold is set, it’s Bondo time!

To avoid the Bondo sticking to the mold, apply some more Vaseline inside the mold.

Then mix the Bondo. I like to mix my Bondo on a piece of cardboard, and with a paint stir stick. Put a blob of the Bondo base onto the cardboard. Then squeeze some hardener on the Bondo. Then mix it together really well, but also very quickly because Bondo dries fast!

Make sure the Bondo is a pink or blue color. If there is not enough hardener in the Bondo, it will not cure correctly. Here’s our Bondo Wood Filler review to learn more about the pros and cons of using this wood filler.

Then fill the mold up with the Bondo. While the Bondo is still wet, press the mold onto the damaged surface. Hold it in place until the Bondo starts to harden. You don’t want it to harden all of the way though, so this should only take about 5 minutes max. Then carefully remove the mold from the Bondo.

If you notice any major excess Bondo, get rid of it quickly with a utility knife before it hardens completely. Allow the Bondo to dry for about an hour and then sand it with 100220 grit sandpaper to shape it to your satisfaction.

You might find small holes or gaps in your repair. That’s where some regular wood filler comes in handy! Wood filler is not strong enough for a large repair, but it is great for tiny holes or cracks. Fill them up and let dry. Then sand the wood filler smooth again.

And here’s our list of other best wood fillers for furniture so you can decide which one is right for your project. We also listed the best wood repair putty that we have personally tried and tested.

Using KwikWood to Repair Dog Chewed Trim

For those who prefer a simpler solution, KwikWood is a great alternative. KwikWood is kind of like playdough for adults (and super handy for DIYers). It has a clay-like consistency that makes it easy to shape and mold into any form you need.

To use KwikWood, you’ll need to cut off how much you want from the stick of Kwikwood, then mix the two parts together until they’re completely blended. Make sure to wear disposable gloves to protect your hands here.

Once you’ve done that, you’ll shape it to fit the damaged area of your trim. Unlike Bondo, KwikWood gives you a little more time to work, around 10-15 minutes, so you can really make sure you have the shape just right.

After you’ve got your KwikWood shaped and molded, you’ll need to let it dry for an hour or overnight. Patience is key here! Once it’s completely dry, you can shape and smooth it out with 100-220 grit sandpaper.

If you find any small holes, just fill them up with a bit of wood filler and sand it smooth again. Learn more about how to use KwikWood here.

Painting or Staining the Repair

Finally, it’s time to paint or stain your repair!

When painting the repair, make sure to prime the repaired area before painting to create the best results. It is super important to prime before painting because it helps make the application smoother and improves how well it sticks.

Here is our list of the best primers for painting furniture so you can choose the best one for your project. Once the primer is dry, you can paint over the primer with the original paint if you have it on hand.

You can also color match paint at a hardware store to match it to the original color. If you aren’t sure what paint to use, here is our list of the types of paint for furniture.

If your repair is on raw or stained wood, you can stain the repair to match!

Just use this wood stain repair kit to apply layers of the same tones in your wood to make it look like the wood. It’s easier than you might think honestly. Here is our wood stain repair guide to help you with staining your repaired wood.

And there you have it – an easy and effective method to repair any dog-chewed wood trim, making sure your home stays looking its best for years to come. Remember, with the right tools and a bit of patience, there’s no scratch, nibble, or chew that can’t be fixed.

So, keep this guide handy for those little accidents, and continue to enjoy every moment of life with your four-legged companion.
