How to Join Sheets of Wood

Updated February 21, 2017

When you need a bigger sheet of wood than what you have available, you can either purchase a sheet the size that you need or you can make a larger sheet by joining smaller sheets of wood together. One type of wood that you can join together is Balsa, which is a light wood that can be easily joined by using glue and a few pieces of tape.

Lay the sheets of wood together on a flat surface, such as a table. Align the sheets so they are laying together side by side.

Apply two to three small pieces of painter's tape horizontally across the joints on the top side of the wood.

Turn the piece of wood over and apply a long strip of tape vertically over the centre of the joint.

Remove the pieces of tape from the opposite side of the wood.

Bend the piece of wood so that there is a gap in the joint. Set the piece of wood so it is in the shape of a triangle on the table.

Brace the sides of the wood to keep it upright and then run a bead of wood glue along the inside of the joint.

Lay the piece of wood flat so the gap in the joint is closed. Wipe up any excess glue with a paper towel.

Place a small amount of acetone on the paper towel and clean any remaining glue residue off of the wood. Let the piece of wood set for about 15 minutes to allow the acetone to dry.

Apply small strips of painter's tape horizontally over the joint and then turn the piece of wood over on the opposite side.

Remove the long strip of tape and then place more small strips of tape horizontally across the joint.

Wait at least 12 hours for the glue to completely dry and then remove the pieces of tape.

Repeat this process for additional sheets of wood that you need to join.


If you are using thicker sheets of wood, you can use clamps to hold the pieces together while the wood dries.


Be careful when removing the tape after the glue has dried, or you can damage the wood.
