What is the difference between wood epoxy and wood filler?

Wood epoxy and wood filler are two different products. They can both be used to repair damaged wood, but they each have their own unique properties and uses.

The choice between the two is a matter of preference: you should choose the one that best suits your needs for that project.

Can I use epoxy as a wood filler?

You can use epoxy as a wood filler. Epoxy is a great way to fill holes, cracks, and gaps in wooden surfaces. It’s also good at sealing and repairing woodwork.

If you want to use epoxy as a wood filler then it’s important that you buy the right kind of epoxy for the job. Some types of epoxies are designed for specific tasks:

  • For filling holes and cracks in wooden surfaces – use an exterior grade resin with microspheres (the small balls). These resins will flow into all the nooks and crannies but they won’t harden until they’re exposed to UV light (sunlight). When this happens, they harden quickly so it’s important not to touch them until they’ve dried completely.
  • For sealing large areas such as decks – use an adhesive grout instead of a resin as this will give better adhesion between your decking boards without leaving any unsightly residue behind once it has dried out completely

Is epoxy stronger than wood filler?

Epoxy is a two-part adhesive that includes resin and hardener, which come together to form a cured bond. Wood filler, on the other hand, is often made of similar materials but it doesn’t require any curing process.

That said, epoxy tends to be stronger than wood filler because it takes longer to dry and cure completely as compared to fillers which are quick drying.

That’s not to say you can’t use fillers instead of epoxies if you’re in a hurry—but if strength is your main concern, then epoxy might be better suited for your project needs.

Epoxies tend to cost more than wood fillers due largely in part because they’re more expensive materials used in their production process (in addition).

So even though they may be stronger and more durable than their cheaper counterparts (filler), their higher price tag may keep some people away from using them on their projects or buying them all together!

What is better than wood filler?

Before we discuss the differences between wood fillers and epoxies, let’s take a look at what each product is used for.

Wood filler is a two-part adhesive used to fill in minor cosmetic defects in wood. It can also be used as an adhesive for certain types of flooring materials such as vinyl sheet flooring, tiles, and carpets.

As you might expect from its name, it is made of sawdust mixed with glue or resin (or both) that can be brushed or rolled onto the surface of your project without any need for additional tools.

Once applied and dried, it creates an invisible bond between your piece of furniture and whatever material you are using to cover it – whether that’s paint on a tabletop or carpeting in your living room!

Epoxy resins are stronger than wood fillers so they’re often chosen over them when filling gaps/cracks or making repairs because they won’t break down under heavy loads as other types might do over time given enough pressure being put onto them during use.”

Which is better wood putty or wood filler?

If you’re going to be filling large areas with wood filler, then wood putty is your best bet. It’s easy to apply and doesn’t shrink or crack like other types of fillers.

However, if you’re looking for something that can be used on vertical surfaces such as walls, doors, and frames as well as flat surfaces like tables and shelves, then epoxy is the better option.

Because every person has different needs when it comes to applying their wood filler (or putty), it’s best that you decide which one works best with your project before starting.

When should I use epoxy on wood?

  • If you have a crack that is deeper than the thickness of the wood or a hole in the wood, use epoxy. This is because it will fill up any nooks and crannies that are below the surface of your board.
  • In addition, if you want to fill an area larger than 2″ x 4″, then also opt for epoxy. It’s simply more efficient at filling large areas than standard wood filler would be.

What can I use to fill cracks in wood?

Epoxy is a good choice for filling cracks. It’s strong and can be used to fill gaps up to 3/4 inches wide. Epoxy is more expensive than wood filler, but it also lasts longer and won’t shrink as much as filler does over time.

If you have a lot of large holes or deep cracks in your wood that need filling, epoxy is probably the best option for you.

But before you go out and buy some epoxy, there are some things that you should know about this type of product:

  • The adhesive component will harden quickly when it comes into contact with air—which means it will start drying right away if you’re not careful! This can make managing the application very difficult if there’s any moisture left on your surface (like water). It’s important not to let any excess spill onto other parts of your project because otherwise, they’ll likely get stuck together until they dry completely (which could take hours).
  • After applying epoxy carefully scrape away any excess material using something like sandpaper so that only what needs fixing remains behind; otherwise there may be areas where no glue has been applied at all which could cause problems later down the road when trying to smooth out those surfaces again later down another day or month when working back over them again after waiting 24 hours for each new layer dries fully first…

Does wood filler get as hard as wood?

In general, wood filler is more flexible than epoxy. Epoxy is more flexible than wood filler. Wood epoxy is the most rigid of all three.

Wood epoxy may have a higher initial cost and be difficult to apply without special tools, but it’s the best option overall if you’re looking for a product that will last longer than either type of filler.

What is the toughest wood filler?

Epoxy is the strongest and most durable of the two. It’s also more expensive and difficult to work with than wood filler, but if you’re looking for a product that can hold up against wear and tear over time, epoxy may be your best bet.

Wood filler is an easy alternative for simple home projects that don’t require a lot of durability or strength—like repairing small holes in furniture or fixing cracks in walls.


There are many things to consider when trying to decide on the best wood filler for your needs. Make sure you understand what type of project you will be working on as well as your personal preferences before choosing a product.
