What Is Epoxy Wood Filler?

Epoxy is a material you use to fill holes, cracks, or gaps in wooden surfaces to maintain their primary structural integrity. Epoxies are available in the form of pourable liquid or epoxy putty.

Epoxy is a durable substance and adaptable. It easily adheres to almost any surface and offers a super long-lasting bond.  Most epoxies are water-resistant, sag-resistant, heat-resistant, and are suitable for interior and exterior use. 

Epoxies are available in different varieties, including those with extremely low volatile organic compounds (VOCs) levels. Is epoxy resin food safe? Within this range, you’ll find epoxy resins designated as safe for food-related applications and those not intended for such use.

When to Use Epoxy Filler for Wood

Use Epoxy Filler for Wood

You use an epoxy wood filler when repairing old wood that is either too challenging to remove or too pricey to repair. You use epoxy wood filler to fill gaps and cracks on the wood surface.

You can shape epoxy putty to repair damaged door frame and window frames. Epoxy filler adheres well to create long-lasting wood surfaces.

Use an epoxy filler when the element would be strenuous to clone with new wood, such as molded portions that would need advanced machining or grueling handwork.

You use epoxy fillers when you can’t easily remove an element without disassembling other components’ for instance, a pegged window sill.

You opt for wood epoxy resin filler when most of the element is still usable because there would be no need for replacing wood.

Epoxy becomes valuable when you require restoration and repair on surfaces already coated with epoxy. This approach provides a solution for addressing imperfections and renewing the appearance by applying epoxy over existing epoxy layers.

How to Choose An Epoxy Wood Filler – Factors to Consider Before Buying the Best Epoxy Wood Filler

We all want the best in everything. However, what you consider perfect for you may be trash for another person. The same is true when it comes to wood epoxy resin fillers.

There are different types of epoxy resin. Each has a set of properties suitable for various applications. Woodworking epoxy fillers differ in thickness, heat resistance, the time it takes to cure, the sturdiness of the finished project, etc.

Below are factors you should consider when buying epoxy wood fillers to help you pick a wood epoxy deal for your unique project.

Indoor and outdoor use 

Before buying an epoxy wood filler, consider whether you need to use it inside or outside the house. Some epoxy wood fillers are suitable for indoor and outdoor use.

Others are formulated uniquely for either exterior or interior use to improve durability due to exposure to the elements such as UV rays, moisture, ice, humidity, etc. 

Stain or Painting

Before spending a dime on resin wood filler, check if you can paint or stain it to match the surrounding wood to stop it from being noticeable. 


Confirm whether the size of the bottle of epoxy resin you wish to buy will cover your project to cut costs. Suppose you purchase several small-size containers to complete a considerable task.

In that case, It’ll cost you more than buying one larger-size bottle. Also, buy the epoxy resin you can use in one go to avoid wastage. Some epoxy resins may harden if you store them for too long after use. 


You need your wood epoxy repair to last as long as possible before showing signs of wear. Consider the following vital specifications when purchasing epoxy resin for wood repair to ensure durability.

Abrasion Scratching – Wood epoxy repair projects should withstand wearing. Do not use epoxy resin-coated surfaces as your cutting board as they get visible scratches. When buying a wood epoxy, opt for one that won’t easily show scratches.

UV Damage – Sadly, most woodworking epoxy fillers are extremely sensitive to UV damage. Opt for Non-yellowing formulas for outdoor use as they can significantly hold out the sun rays and last for a long time.

Consider buying a UV-resistant topcoat in addition to your favorite finish. UV rays can damage even UV-blocking epoxy resins after prolonged exposure.

Water – Water makes epoxy wood fillers wear faster than expected. To ensure durability, buy epoxy wood filler waterproof for outdoor use. Also, leave epoxy wood filler to cure before exposing it to any wetness.

Color matching

Buy an epoxy filler that will match the color of the surrounding wood when cured. If you can’t find an exact match, purchase a stainable or paintable one and then stain it to fit the nearby wood.

Staining wood filler would help in color matching. You can also opt for a clear epoxy wood filler.

Drying time

Cure/ drying time stipulates how long you should wait before sanding or continuing your epoxy wood project. Epoxy temperature and hardener cure speed determine epoxy resin’s cure time. 

Every hardener has a specific temperature cure range that works best for it. Select a hardener that will provide you with enough working time for your project at the temperature and conditions you will be working in.

Longer curing times give you more time to work on your project. You’ll be able to shape it the way you want, and you’ll have enough time to correct errors.

Note that it’ll take you longer to complete the project. Quick curing time necessitates quick work. You have little time to get creative or amend errors, but you’ll finish your project in record time. 

How to Use a Wood Epoxy Resin Filler

How to Use a Wood Epoxy Resin Filler

We’ve already looked at the best epoxy resin fillers for repairing and restoring wood, so let’s look at the process of working with epoxy. Follow this step-by-step tutorial to learn how to use epoxy resin filler.

Prepare The wood

Before you begin applying the wood filler, you must first clean the wood. To see how severely the wood is damaged, you must meticulously remove any dirt or paint you may need to sand it or use a paint stripper to clean the surface.

After a gentle sanding process, ensure the wood is free of dirt, grime, algae, and sanding dust.

Apply an Epoxy Consolidant

When you’ve finished preparing the wood, it’s now time to make the epoxy resin wood filler. Apply an epoxy consolidant to the entire surface you’ll be working on first.

An epoxy consolidant is a thin covering of epoxy that coats all of the fiberboards together by a resin. Allow the surface to dry completely before proceeding to the next step.

Fill the crack with Epoxy Eternal Wood Filler

Fill in the cracks in the wood with epoxy putty once the consolidant has fully cured. This is because holes in wood tend to broaden much further.

The very worst scenario is that the gap is created by insects, which will form a hole right through the wood. If you pour the liquid wood filler too soon, it may drip through these gaps and run through the insect hole.

So, to avoid this process, apply wood epoxy putty. Make a paste by combining two parts epoxy filler.

Seal all cracks thoroughly, and don’t worry about developing an even finish because you will sand down the surface later.

Pour the Liquid Wood Filler into the hole

Allow the wood epoxy filler putty to cure before pouring the liquid wood filler. Mix the resin with wood filler liquid to achieve a pourable consistency.

Pour it all over the wooden surface and let it seep into all the insect holes and cracks. Now apply the liquid filler to the remaining gaps and cracks. 

Allow the filler to absorb in for a few minutes after being filled. At this point, the epoxy will have dropped slightly. Then pour some more epoxy filler until it has filled all the cracks and holes or is no longer falling.

Finish the Wood

Before finishing the wood surface, ensure the epoxy filler has wholly cured. The brand and the manufacturer’s instructions will determine this.

However, it is recommended that you wait at least 24 hrs before using the wood surface again. 

After it has fully cured, sand the surface until it is even and smooth. You can sand by hand or with an electric sander.

Why Use the Best Epoxy for Wood Repair?

There are several reasons why you should use epoxy for wood repair. Let us look at some of them.

Epoxy Wood Repair For Beauty

Some of the best epoxy wood repairs are compatible with a wide range of pigments, allowing for an excellent array of different tints. These tints add color to epoxy wood repairs and enhance the aesthetics of refurbished wood surfaces.

Epoxy For Durable Wood Repair

Other epoxy wood repair agents are unrivaled by the bond between the resin wood filler and the wood surface. Epoxy bonds exceptionally well on the wood surface, infiltrating it to provide military-grade lifetime durability.

As a result, epoxy wood repairs are scratch and abrasion-resistant, UV resistance, waterproof, and pressure and impact resistant.

Epoxy Wood Repair in 2 Ways

By trying to perform wood repairs in two different ways, you can enjoy the benefits of the methods by which epoxy wood filler works. One method is the consolidation method.

The damaged or deteriorated rotten wood surface is fully saturated with the best epoxy for wood repair. The second method is the filling method.

The damaged part of the wood is eliminated to expose only the fresh and healthy wood surface to which you apply the epoxy primer and epoxy filler.

Tips and Tricks for Using a Wood Epoxy Resin Filler

Make sure you’re prepared for the overall process before mixing the two-part epoxy. There is only a limited amount of time before the epoxy dries up. Have everything you need in front of you before mixing the epoxy.

You should also work more quickly after you’ve mixed it. Mix only the quantity of epoxy wood filler you intend to use. If you have any extra unused epoxy, store it for use later. 

When the liquid wood filler has fully cured, some minimal depressions may remain in the wood. This can be remedied by using wood epoxy putty. Apply the epoxy wood filler to the holes and cracks and any other areas of the house that require it.

The temperature determines the time required for the epoxy resin filler to cure fully. For the best outcomes, work in warm temperatures. You can also use heat to speed up the curing process.

Because epoxy is plastic-like, it will take much longer to sand. It necessitates a gentle sanding procedure that may require additional sheets of sandpaper. As a result, you must be patient!

You can either contain the wood with a cover or do the procedure inside while the filler cures. This is because dust and dirt can affect or stick to wet epoxy.

Before you begin this project, remove any decayed or rotted wood. If the wood epoxy putty becomes too wet, it will collapse, widening gaps.
