One of the first steps in wood filler repair is assessing the damage. Figuring out whether the damage is artificially on the surface, or structural is a good way to see if you can do the wood repair yourself or if you need more expertise. It’s important to look for signs of moisture damage and evaluate the depth of the wood rot. Keep in mind that not all of the wood  will be visibly damaged.

2. Prepare For The DIY Process

When doing a DIY epoxy wood filler project, there are a few steps to get prepared for. Steps will include gathering the tools and following all safety measures.

3. Remove the Rotted Wood

The next step in the DIY epoxy wood filler process is using a rotary tool or router with a V-bit to grind/sand out any damaged areas. It’s crucial that you take out ALL of the damaged areas to make certain you are not just covering them or adding the epoxy on top. In this step you are trying to get out all of the loose materials, like the wood and any paint. 

4. Let the Area Dry

One of the most important steps in the DIY epoxy wood filler process is making sure the area you are looking at is completely dry. In order to guarantee your wood rot won’t get worse, the area has to be dried 100%. Ensuring all of the moisture is gone before applying anything to the wood is key before applying epoxy. Having moisture underneath the epoxy wood filler repair can create bubbling or further the wood rot. 

5. Apply a Wood Hardener

The next step is to apply a wood hardener. This is an optional step but it is highly recommended, especially if doing this project by yourself. You will brush on a bonding agent to the exposed wood you are working on. This is to help the epoxy apply better and more smoothly as well as help the adhesion. It will help because it stabilizes the remaining wood fibers. It is a liquid resin that soaks into the wood to make this happen. 

6. Mix the Epoxy Wood Filler

Before applying the epoxy, you will need to mix the epoxy wood filler together to get it ready to apply. You will need to use something to mix it, either manually or a drill with a mixing blade. Follow the mixing directions according to the type of epoxy you bought to make sure you are doing it correctly, each one is a bit different. Typically, you will need to mix until the color is uniform to ensure it is ready for effective curing.  

7. Apply the Epoxy Filler

While applying the epoxy may be one of the harder parts in this process, there are a couple of things you can do to make it easier. The epoxy will be pliable before curing, with your gloves on, try your best to fit it into the shape of the wood you are repairing. Packing the filler deeply with a putty knife will make sure that there are no air bubbles that may compromise your repair. It is important to work quickly and carefully, and it’s okay to slightly over fill the area since you will be sanding it later. The real challenge will be to match any contours in the wood. 

8. Let the Filler Cure

Next, in the epoxy wood filler process, you will need to let the wood fully cure. The curing time is, again, different for each type of epoxy and will depend on what type you buy. The times can range from about 30 minutes for rapid curing products, to several hours, most people just wait overnight. This is another time where you must follow the manufactures directions very strictly to get the best and strongest results. 

9. Sand the Surface

After completely curing, you will need to sand down the surface with coarse grit sand paper. It is best to start with a coarse grit and then move to more fine grit to get the surface as smooth as possible. Professionals will ensure a flawless blend between the original surface and the newly fixed surface. Doing this on your own is possible but will be a lot of labor. Dust removal is another key for before painting, it is best to use a damp cloth after sanding. 

10. Prime and Paint

The last step in repairing wood rot with epoxy wood filler is painting or staining the area to match the rest of the surface. This step will depend greatly on the type of wood you are repairing. As an overarching idea, it is best to start with a layer of primer. Next you will paint one to two coats of the desired paint/stain. It is highly recommended by professionals to top these coats off with a sealant to protect it from future damage
