Here comes a DIY Project for making an outdoor bench. With all the supplies listed below, you can have a new, inexpensive, and modern outdoor bench. Go give it a try!


  • Table saw
  • Rag
  • Paintbrush
  • T-square
  • Sanding blocks with 120 grits and 80 grits
  • Thompson’s Waterseal and Stain
  • Surgace protection such as tarp, cardboard box
  • Bar clamps
  • Exterior grade Titebond III or Liquid Nails
  • Hand held belt sander with 120 grits and 80 grits
  • Four feet and drill (to make the bench not touch the ground)
  • 2x4s pine

Cut list:

  • 4 pieces of 40” long cuts
  • 5 pieces of 22.5” long cuts
  • 8 pieces of 12.75” long cuts
  • 10 pieces of 16” long cuts

The Steps:

  • Take each piece of wood and mill the edges for 2” to make the edge square and no longer round. Square bench will make the look of the bench more modern. Mill the wood with table saw. But you can also make the faces of your wood more parallel using a planer.

  • Referring to the cut list, cut your wood based on the sizes above. All the pieces of the wood, when assembled, will create a bench with the size of 13.5” deep x 40” long x 16” high. If you want to make bigger or smaller benches, make some adjustment to the sizes accordingly.

  • Have your liquid nails and box clamps ready. Put the 40” long wood on the floor with the 33”5 cut in the center of it. Place a 16” long perpendicular piece at every end of the wood. Ensure that you make place every piece evenly and as flush as possible. Get the help from t-square to get a perfect angle. Then, secure them with clamp and glue.

  • To get the idea of the final joints of all the bench pieces, try to organize them without applying glue. Then, when you are already sure that every piece is perfect, start applying some liquid nails at the end of the bench to begin the assembling. As you are working with the assembling, get a help from box clamps to get the right attachment.

  • Keep your bench clamped although you are done with the assembling. Let the clamp tighten the attachment and let the glue dry for a night.

  • Then, remove the clamp. Take your belt sander to sand uneven surface and the grain. Make sure you keep sanding until all surface and edges are flat and smooth. After that, wipe all the dust away. If you think your bench needs more even-ing, sand it with 80 grit and then with 120 grit sand.

  • Next, paint your bench using the stain and your brush.

  • Your bench is complete now!
