Epoxy fillers for wood are adhesives used to seal up wood damages like rot and cracks, etc. They are widely used for wood repair because they give damaged wood a durable finish so there’s no need to replace the wood. Epoxy wood fillers are made from a mixture of resin and hardener, which are mixed to form a putty-like consistency.

After wood filler is applied and it cures, the epoxy wood fillers can be leveled and colored to mask repaired surface and make it blend with the wood. They are resistant to water, UV light, and other external elements, that’s what makes them a great option for indoor and outdoor use. This article will cover the various kinds of epoxy wood fillers available, how to use them, and some tips for achieving the best results.

Types Of Epoxy Wood Fillers

In the market, several types of epoxy wood fillers are available for purchase and use. They are available for purchase in different forms and have peculiar properties depending on the brand. They usually come in the following forms:

Pourable (Liquid) Epoxy Wood Filler

The pourable epoxy wood fillers come in liquid form that is easy to prepare and apply to cracks in wooden structures, tables, and other furniture. After application, the liquid epoxy filler is left to cure, which can then be sanded to make the surface even.

Two-Part Epoxy Wood Filler

A 2-part epoxy wood filler comprises a hardener and resin mixed in a ratio recommended by the manufacturers. The combination results in a thick mixture commonly used to repair and fill up gaping holes or cracks in the wood.

Powdered Epoxy Wood Filler

Technically the epoxy filler is not used in powdered form. Powdered wood fillers are mixed with epoxy resins to achieve a thickness. The mix is used to seal up the cracks in wood and repair other little errors. One of the reasons why woodworkers commonly use it is its ability to bond well with wooden surfaces.

Exterior Epoxy Wood Filler

There are epoxy fillers that are made specifically to be used for outdoor woodwork. Some properties that make them suitable for exterior use are their high UV light tolerance and moisture resistance. They commonly repair wooden decks, doors, fences, etc.

Colored Epoxy Wood Fillers

Although epoxy wood fillers can be painted and stained there to the colors of your choice, wood fillers come in a range of custom-made shades. This is a welcome option because sometimes it is difficult to find paint or stain that matches the pre-existing color of the wood being repaired.

What Are The Benefits Of Using Epoxy Wood Fillers For Your Wood Repairs?

Epoxy Wood fillers are one of the common ways of fixing damages. Other options include replacing the entire wood or using regular wood fillers. However, using epoxy wood fillers has many advantages as opposed to using traditional wood fillers or replacing the whole work.


Epoxy wood fillers are far more durable than regular wood fillers; they have been known to last longer than the wood they are used to repair. Plus it protects the sealed areas from new damages for a prolonged period.

Saves Time

Using epoxy wood fillers is more time-saving than doing a complete replacement. Especially when dealing with large-scale projects, using epoxy wood fillers will reduce the time spent doing a new project. Handling repairs will take a short time, and the finished work will still be durable enough to last a couple more years.

Saves Cost

Epoxy wood fillers are more pricey than regular wood fillers. But using them to repair damages is much cheaper than embarking on a new project to replace any wood works that need repairs. Except a substantial portion of wood has been weakened beyond the point of repairs, it’s better to go for the more pocket-friendly alternative.

Frequently Asked Questions

How Can You Apply Epoxy Wood Filler?

Applying epoxy wood filler is a straightforward process, but there is a proper way to go about it. Before using any epoxy wood filler, prepare the wood by drying it thoroughly and checking the extent of rot/damage. Get rid of any rot in damaged regions so the surface doesn’t keep rotting even after wood filler has been applied.

Then you’ll prepare and apply your consolidant and filler afterward, and once it’s dry, you can add some color.

Can I Paint Over An Epoxy Wood Filler?

After applying epoxy wood fillers to seal damaged and cracked wood surfaces, you can paint over it or stain the wood filler. Allow the wood filler dry for up to 24 hours, then prime and sand the surface to level it, so it’s relatively easy to paint and stain the epoxy wood filler.

Is Wood Filler Waterproof?

It depends on the product. While most manufacturers claim their epoxy wood fillers are waterproof, when you try using some of the products, you’ll quickly discover that not all are fit for outdoor woodwork.

You will notice that the water that gets on the surface will cause the places where the wood filler was used to begin to crack up. However, customer reviews are an excellent way to know if a wood filler is genuinely waterproof.

How Long Does Epoxy Wood Filler Take To Dry?

Epoxy wood fillers take about 30 minutes to dry, typically under optimum weather conditions. However, you can leave it overnight or for at least 24 hours before sanding.


Finally, epoxy wood fillers are a valuable tool for repairing and filling in wood surfaces. They offer a strong and durable solution and its resistance to moisture and external elements, makes it perfect inside and outside repair projects. Epoxy wood fillers are also easy to work with and can be sanded, painted, and finished to match the surrounding wood.

However, following the manufacturer’s instructions carefully and allowing the filler to fully cure before proceeding with any additional steps is crucial. With proper use, epoxy wood fillers can help you achieve professional results and extend the life of your wood projects.
