are wood filler and wood glue the same?

Filling the gaps in a piece of wood or furniture is one of those tasks that seems simple but can be surprisingly tricky.

The two most common types of fillers are epoxy and polyester resins. Both of these are available at home improvement stores and are easy to use, but they have their own quirks that can make them more suitable for certain situations than others.

What happens if one type doesn’t work as well as you expected? Is there anything else you can try? Let’s take a look at these two options and see how they stack up against each other:

Can wood glue be used as wood filler?

Yes, wood glue can be used as wood filler. Wood glue is not as strong as wood filler and should not be used to fill large gaps or defects in the wood because it will shrink over time.

It is better than using nothing at all and it’s cheaper than buying a product specifically designed for that purpose, so if you don’t have any on hand, using some glue may be better than going without altogether.

While wooden glues are not designed specifically for filling small defects or gaps in your furniture projects, they do work well enough for this purpose if there isn’t much of a gap involved (less than ¼ inch).

Glues will also dry clear (unlike most stains), which means that they can help hide less-than-perfect areas of your project before painting begins on top of it!

Can you use Gorilla wood glue as a filler?

You can’t use Gorilla wood glue as a filler. It’s glue!

Filler is a different product altogether. A filler is used to fill holes in wood, so it’s more of a paste than glue.

This paste dries after it’s applied and makes your piece look like new again.

Wood filler comes in different types (caulk, putty) but they all work the same way—they fill in holes or cracks and smooth out the surface of your project nicely so you don’t have to worry about any blemishes or unevenness when you paint later on.

What can I use instead of wood filler?

If you need to fill a gap, consider using caulking first. This is a good solution for filling gaps that are less than 1/4 inch in diameter.

You can use caulking to repair cracks and holes, but you’ll need to make sure that the caulk adheres well to the surface of your wood before installing it.

Wood putty can also be used as an alternative to wood filler or wood glue if you’re looking for something more versatile.

Wood putty is sandable and paintable once dry, which means that it’s easy to adjust texture on your project after installation.

However, because wood putty isn’t waterproof like most caulks are (unless they’re silicone-based), it won’t last as long as caulking will if exposed directly to moisture over time

How much gap can wood glue fill?

Wood glue is not as strong as wood filler. A common question that people ask is “How much gap can wood glue fill?” The answer to this question depends on a number of factors: the size of the gap, how much pressure is applied to fill it, and how long you let it dry before applying pressure.

Wood putty works similarly to wood filler because they both adhere to wet or damp surfaces better than dried ones. However, because it’s composed of fine particles (like sawdust), it tends not to leave gaps behind when applied correctly—but if you’re not careful when applying, you could end up with clumps instead of even coverage across your surface area!

Wood putty usually has a medium thickness compared with other types; this means that although it may take more product per square foot than some other products out there (like Liquid Nails), less product will be needed overall due to its lightweight compared with other materials like epoxy glue which tend toward being thicker and heavier overall despite being made from similar ingredients–that being said though there are some disadvantages such as having difficulty working with small spaces since many epoxies come out at room temperature, unlike other types which must always be mixed together beforehand using heat from somewhere else like an oven or stovetop burner.”

Is wood glue or wood filler stronger?

The answer to this question depends on the type of wood filler or glue you’re using. While wood glue is stronger than wood filler, it doesn’t fill gaps as well.

If you need to fill a large gap, use wood filler; if you need to glue two pieces of wood together, use wood glue.

Can you use Liquid Nails as wood filler?

The short answer is that you can’t use Liquid Nails as wood filler. However, we would like to point out that it’s not a good idea to use any polyurethane adhesive as a wood filler or wood glue.

Polyurethanes are strong adhesives and will bond well with most surfaces, but they’re just not meant for this purpose.

Polyurethane is great for bonding things together permanently, but it doesn’t soften when it dries out like some other adhesives do and can sometimes even stiffen up over time—so that’s why we don’t recommend using polyurethanes as fillers or glues under any circumstances!

How do you fill wood cracks with glue?

  • Apply a generous amount of wood glue to the crack and spread it evenly.
  • Press the pieces together, applying even pressure from all directions.
  • Allow the joint to dry before moving on to the next step, which is…
  • Sand any excess glue flush with the surface of your project and then seal it with wood filler or spackle. Apply a thin layer—too thick and you’ll see bumps after you paint over it! This can be done with an old credit card or another hard plastic tool that has been run along both sides (front and back) of each side piece where they meet in their middle; smooth out any bubbles that form while spreading out the adhesive so they don’t show through later on when painted over top. Let dry completely before moving on to the next steps listed above: priming/painting a new joint area covered by filler/spackle sealant

Can I use caulk instead of wood filler?

You can use caulk to seal small cracks and gaps. Caulk is a good choice if you are working with a small area, but it doesn’t have the strength of wood filler, so it won’t be able to fill deep gaps or large holes.

Caulk also isn’t permanent, so it may be harder for you to fix any problems later on down the road.


There are many differences between wood filler and wood glue, but it all comes down to what they’re used for. If you’re looking to repair a small crack or hole in your wood furniture or shelves, then either product could be the solution.

However, if you are trying to reattach pieces of a broken piece of furniture or make something new like a shelf/table/desk with two separate pieces of wood glued together then you will need something stronger than just standard glue like epoxy or polyurethane which is why we recommend using epoxy resin instead as it offers more strength and flexibility when working with different types of surfaces.
