Below are answers to some commonly asked questions that we’ve received about epoxy wood fillers.
Will epoxy stick to wood filler?
It depends on what type of epoxy wood filler you’ve purchased. Generally speaking however, epoxy wood fillers are a reliable adhesive so they will stick.

What is epoxy filler used for?
They’re great if you’re looking for a filler that has more structural integrity – perhaps for a widening crack or a rotting void. They come in either a tube or a can and can be either clear or colored – depending on your needs. When using an
How Do You Fill Holes in Wood with Epoxy?
There are a couple of steps that you’d need to take to fill holes in the wood with epoxy.
- If you’re filling rotting wood, you’d need to find and stop the cause of the rot. If you’re not sure what’s causing the rot or how to repair it, it’s best to call a professional for some help. If there’s moisture within the rot, ensure that your wood has about a week to dry properly as trapped moisture can cause additional rot and even prevent the epoxy from bonding properly.
- Then, you’d want to probe the area surrounding the damaged woo to determine the extent of the rot. Soft wood should either be removed or reinforced with epoxy consolidant.
- Once you’ve determined the cause, proceed to remove all decayed wood before applying the liquid wood epoxy consolidant according to the manufacturer’s instructions. You’ll want to work it into the wood with a small brush until the entire wood is saturated. Then, go ahead and let it dry for at least a week before starting the next step.
- Before applying the epoxy, you’d need to go ahead and mix it. As epoxy can harden – especially in warmer weather, you’d want to work with it quickly. Try and keep your epoxy materials as cool as possible when you’re working with it, and you can speed up hardening with a hairdryer or spotlight.
- Then, go ahead and fill the wood cavity with the epoxy wood filler. Start by pressing the putty into the area with a putty knife. Make sure that you’re pressing hard so all voids are filled and there’s a good bond.
- After that, you’ll want to make sure that you’re wearing chemical-resistant rubber gloves to shape the epoxy with your fingers and overfill the repair. You don’t need to get the shape perfect, just make sure that you’ve got enough material leftover to match the surrounding profiles.
- With that, you’re good to go when it comes to filling the hole with epoxy. If it’s warm, you’ll be able to shape it in about three to four hours. If not, you’ll need the patch to harden overnight. Once that’s done, you can go ahead and sand the epoxy or proceed to paint over it.
Tips for Using Epoxy Wood Filler
If you’re new to using an epoxy wood filler, here are some tips to get you started:
- Epoxy should generally be used for large voids, and if you’d like you can also mix epoxy with tints and pigments from an art supply house for an additional touch of colour. When applying, make sure you’re doing so carefully with a knife or wooden stick as it can be difficult to clean up.
- You should always follow the manufacturer’s recommendations when mixing your epoxy, and make sure that you’re using the right ratios to ensure that the glue cures fully and reaches its maximum strength.
- As epoxy generates heat when it cures, it’s best to mix it in smaller batches.
- Take the necessary safety precautions when working with epoxy. It’s important that you’ve got proper protective clothing and safety glasses. Make sure that you’re also working in a well-ventilated space. Long-sleeved clothing is also recommended along with mouth protection.
- When mixing, try and do so in plastic containers as epoxy simply peels out after it has set.
- Epoxy is not UV-resistant, so if it’s meant for the outdoors you should topcoat your wooden piece with an exterior varnish or paint.
