can you use wood glue as wood filler?

Wood filler is an important part of any do-it-yourselfer’s toolkit. Whether you’re repairing a piece of furniture or building something new, it can be hard to find the right type of wood glue to fill gaps and holes in your project.

Wood filler comes in many different forms, including putty and spackle. The good news is that wood glue can also be used as a type of wood filler.

In this article, we’ll look at some common uses for wood glue and how they compare with other types of wood filler.

Can you use wood glue to fill holes in wood?

You can use wood glue to fill holes in wood, but it’s not the best option. It would be better to use a product like Zinsser Wood Putty or Titebond III Ultimate Wood Glue.

If you’re determined to try your hand at using wood glue as a filler, here are some tips:

  • Use a thin layer of glue and allow it to dry before sanding with 100-grit sandpaper until smooth.
  • Apply another thin layer of glue over the first one, let dry again and repeat until there is no more sign of damage or discoloration on the surface you’re working on (this may take several applications).

Is wood glue good for filling gaps?

The short answer to this question is yes, you can use wood glue as a filler. However, it depends on the gap you need to fill.

Wood glue is best used for small gaps and spaces between 1/8″ (3mm) and 1/4″ (6mm). In fact, most carpenters consider it essential when gluing two pieces together.

Wood glue has a reputation for being strong enough to hold large pieces of furniture together but flexible enough not to crack or break over time like other types of filler materials such as putty or joint compound would.

What can I use if I don’t have wood filler?

If you’re in a pinch and don’t have wood filler, but you do have some wood glue that you can spare, then there are a few things it might be able to do:

  • Epoxy glues are strong. They’ll bond two pieces of wood together; however, some epoxies will take longer to cure than others. This means that if your project requires holding something together quickly or lasting for a long time before breaking apart again (like with outdoor furniture), epoxy probably won’t work for you. But if the items being glued are small enough and not exposed to extreme temperatures or weather conditions (like under windowsills), then it could work great!
  • Silicone caulk is another option for filling small gaps in your projects. You can use caulks made from different materials like acrylics or urethanes depending on what type of result you’re looking for (and whether or not those materials will be affected by water). The advantage here is that caulk tends to come in squeeze tubes so they’re easy to apply and control while working with them—which isn’t always true when using other types of glues!

Can I use Gorilla wood glue as filler?

Yes, you can use Gorilla wood glue as a filler for small holes in wood. The glue is strong and durable, making it ideal for filling holes that are too large for wood putty but too small to fill with wood filler.

It dries waterproof and UV resistant, which helps prevent the discoloration or cracking that can occur when using other types of fillers on bare woods like cedar and pine.

Gorilla glue comes in two versions: clear (which is tinted) and white (which is left natural). Either one will work well as a filler, although clear will dry slightly darker than white because it has already been tinted before packaging.

Can you use wood glue to fill screw holes?

If you have a screw hole in your wood and need to fill it, there are several options available. You can use wood filler, which is designed specifically for filling holes and other small imperfections.

Using glue as filler works just fine but requires a little more prep work—you’ll need to let the glue dry before applying paint or stain over it so that the finish doesn’t dissolve the dried glue.

Epoxy is another option worth considering; it’s not as versatile as wood filler or glue but can be used to fill larger holes (upwards of 1/4 inch).

In general, gluing things together is a great way to fix broken items. But it’s even better when you’re using precision instruments like hammers!

How do you fill gaps in wood?

  • When filling a gap in wood, it’s important to use a filler that is compatible with the wood. If you’re working with oak and you want to stain over your repair job, for example, it’s best to use an oak filler—otherwise, you run the risk of making the existing cracks even more obvious once the new material is stained and finished.
  • You should also use a filler that complements your chosen finish. For instance, if you’re going for an antique look on your furniture piece and choose to apply cream paint over top of a repaired crack or hole that was filled with birch fillers, then those fillers will stand out in stark contrast against their white counterpart (which isn’t desirable).
  • After applying glue or paste into those gaps using either brush or trowel (depending on how large they are), allow them enough time to dry before sanding down any rough edges left behind by your chosen type of adhesive.

Is wood glue stronger than wood?

Yes, wood glue is stronger than wood.

The glue you use to assemble your projects is typically a latex-based adhesive that bonds with the fibers in the wood you’re working with.

When it dries, its chemical bond will be stronger than those same fibers or grains of wood. In fact, it’s even stronger than the cells themselves!

That’s because its molecular structure holds together so tightly that if you were to pull on one side of your glued piece of furniture, all of those little cells would break apart before any part of your glue let go—like chains breaking before links snap off.

However, there are some situations where applying too much pressure can cause problems: if there aren’t enough grains in place to support each other and hold everything together properly (such as when using plywood), they may crack apart under too much stress; also keep in mind that if gluing two pieces together requires more strength than either piece has naturally (like when putting together reclaimed lumber), then extra reinforcements might be needed as well.”

Can you use Liquid Nails as wood filler?

You can’t use Liquid Nails as a wood filler because it is not meant to be used as a wood filler. It’s a glue, and while it is strong, it won’t have the same strength and durability as another type of wood filler like epoxy or polyurethane.


As you can see, there are a lot of questions about wood glue and how it can be used as a filler. While we don’t have all the answers yet, we do know that wood glue is an excellent choice for filling holes in wood.

It’s easy to use, affordable and easy to find at any hardware store or home improvement center.
