Things You Will Need

  • Safety mask
  • Flat non-porous surface to mix bondo wood filler

Step-by-Step Processes

Step 1: Sand to Smoothen the Area

First, you have to sand the surface where there is a chunk to smoothen it. Use sandpaper to get a smoother finish. The more you can smoothen the finish, the better you will get the result after applying the Bondo.

Step 2: Mix the Bondo

In the next step, you have to start mixing the Bondo, which comes in two separate parts. Wear a mask to avoid fumes and oiled hand gloves to protect your skin. Follow the directions written on the labeling of that Bondo. You have to choose a well-ventilated area to do this step.

Step 3: Apply the mixture to the Wood Furniture 

You need to start applying the Bondo immediately after mixing it because it dries quickly. You can use a spoon for the application. A putty knife will help you get a smoother finish if you work with a flat surface. If the surface is curved, you should go for more sanding to get a rounded finish. Once you notice the surface is hardening, you should stop applying it and let it dry. 

Step 4: Sand the Bondo

After drying, you have to sand the Bondo to smoothen it. If you notice a few pits and rough edges, you need to do another coat. 

Step 5: Prime and Paint

Once your Bondo is completely dry, you have to prime your wooden furniture. After applying a coat of primer, you will be able to apply the paint. 

Reasons to Use Primer Before Painting 

  • Primer helps the sheen of the paint to be the same. The repaired area gets a different sheet from the non-damaged area without the primer. 
  • With primer, you can cover bare wood’s red, yellow, or orange stains with a coat of paint. 
  • Primer helps cover the dark wood faster while using a light color than the paint.

  • Don’t spread the Bondo mixture too thin while mixing it. 
  • Follow the steps separately to fix the chunks in different sections.
  • Mix only a small amount of Bondo wood filler and hardener at the time. If you take a large amount, it will dry out fast and will not work effectively.
