What to use to fill holes in plywood?

If you’ve ever tried to repair a piece of furniture, you know that even the smallest hole can be difficult to fix.

Depending on the type of wood and material surrounding an existing hole, there are several different ways that you can fill it up.

For example, some woods are more porous than others and will allow for more moisture absorption. If you have a particularly large or deep hole in your project, there may not be any way around replacing it altogether!

Still curious about how to fill holes in plywood? Read on for tips and tricks from professional woodworkers themselves!

How do you fill a plywood hole?

There are several methods you can use to fill holes in plywood. Here’s how to choose what works best for your project:

  • Wood glue. Wood glue is a good option if you don’t need the hole filled in right away. The glue will take some time to dry and harden, so make sure it’s not an emergency repair job before using this method.
  • Wood filler and putty. These products can fill small holes quickly, but they’re not ideal if you have larger areas that need filling—they’re more expensive than other options and tend not to be as strong or durable over time (especially when used on large surfaces).

Can you use wood glue to fill holes?

You can absolutely use wood glue to fill holes in your plywood. And it’s probably the best option for most people.

Wood glue takes longer to dry than wood filler, but it’s also stronger and better suited for long-term applications like this one.

Wood filler is intended as a patching material that will eventually be sanded down, while wood glue performs well over time and resists cracking or peeling away from the surface of your project after it dries.

This makes it ideal for filling holes in plywood—especially if they’re large!

If you’re looking for a quick fix that will hold up long enough until you find more permanent solutions later on down the road, we recommend using Elmer’s ProBond Advanced Wood Glue instead of traditional wood putty or other types of glues (like polyurethane).

The ProBond dries quickly enough so that you won’t have any issues with clogged drains due to excess water content (which happens sometimes when using regular adhesives).

How do you fill holes in wood with wood filler?

  • To apply the wood filler, use a putty knife or small spatula to spread the filler evenly.
  • Let the wood filler dry for at least 24 hours before sanding it smooth.
  • Use coarse sandpaper to remove any excess filler and smooth out your repair.
  • If you want to paint or stain over your repaired area, wait for at least 48 hours after applying primer before doing so.

How do you fill a large hole in rotten wood?

The first step to fixing a large hole in rotten wood is to remove the rotted wood, using a hammer and chisel.

Use heavy-gauge wire bristle brushes on both sides of the chisel and hammer to remove all remaining pieces of rotten wood from the surface, then clean up any loose dust with a vacuum cleaner or compressed air.

Once you have removed all of the rotted wood, fill your holes with wood putty so that they are level with surrounding surfaces.

Let dry for at least two hours before sanding down any excess putty until it is flush with surrounding surfaces. Finish off by applying one or two coats of paint or stain over your patched hole(s).

Can you fix a hole in plywood?

You can fix a hole in plywood. Here’s how to do it:

  • Use wood glue to fill holes. You will need a small amount of wood glue and clamps or tape to hold the materials together while they dry.
  • Use wood filler to fill holes. Wood filler has similar properties to paint, so if you don’t want your repairs visible, this is a good option for concealing them.
  • Use Gorilla Glue brand epoxy putty (or any similar product) instead of other glues or fillers because it dries hard like plastic, which makes it perfect for filling large gaps or holes; however, make sure you follow the instructions on the package carefully before using this material!

What is the difference between wood putty and wood filler?

  • Wood putty is a paste that is used to fill holes in wood.
  • Wood filler is a thick paste that is used to fill holes in wood. It usually has some plasticizer or wax so it will stick and remain soft for shaping and sanding.

Should I use wood glue or wood filler?

You should use wood glue for wood to wood joints.

You should use wood filler for wood to metal joints.

Wood glue dries clear, while most of the time, wood filler will dry white (although there are exceptions).

Wood glue is stronger than wood filler and can be used on wet surfaces, which means that you don’t have to wait for any surface preparation before applying it.

Can you use Gorilla Glue as a wood filler?

Gorilla glue is wood glue, not a wood filler. Filling holes in wood with gorilla glue may be possible but it’s not the best option for filling large gaps or cracks.

Gorilla glue has great adhesive qualities which make it an excellent choice for repairing small chips and cracks in wooden surfaces, however, the strength of Gorilla Glue is only equal to that of plywood itself so larger holes should be filled with other materials such as sanding putty or epoxy filler (which can also be used on bare metals).


In conclusion, we recommend using wood putty or wood filler for small holes in your plywood. It is easier to work with and you can use it to fill any size hole.

If you have a large hole, consider buying some epoxy glue and mixing it with sawdust or sawdust mixed with water.

This creates a very strong bond between the pieces of wood so that they can be mended together again like new!
