New Titebond Fast Set Polyurethane Construction Adhesive and Building a Sandbox

Building a Sandbox

1.) Gather Supplies – The area we had available was roughly 10’x14′ so it easily could accommodate a box 8’x8′. I picked up 5 – 2x10x8′ green treated planks (that were all exactly the same length), a short 4′ treated 4×4 post, some 3″+ construction screws and a tube of Titebond Fast Set Polyurethane Construction Adhesive.Titebond Sandbox-1

2.) Cut up the 4×4 – Cut the 4×4 post up into 4 pieces that are the width of your 2×10 planks. They can be a hair shorter but if they’re too long the seats will have a hard time laying flat in a later step.Titebond Sandbox-2

3.) Apply adhesive to one face of the 4×4 and screw the plank flush to the 4×4 section. Do this to both ends of two planks.Titebond Sandbox-3

4.) Tip up the two assemblies, apply adhesive to the near ends of the two remaining 2x10s, tip them up and screw them off to the 4x4s. The sandbox now resembles a box shape.Titebond Sandbox-9

5.) Take the remaining 2×10 plank over to your miter saw, set it to 45 degrees and cut a trapezoid piece with 6″ being the “short to short” measurement. If you have a 12″ sliding miter saw you can make this cut in one pass.Titebond Sandbox-5

6.) Square up the box by pulling your tape measure to opposite corners and comparing the measurement from the other two corners. Once the box is square, glue and screw down the seats. The seats act like gussets to help the box remain rigid and square.Titebond Sandbox-6

7.) Fill it up with sand and enjoy. The sandbox is roughly 8’x7′-9″x9-1/4″ or almost 48 cubic feet. That’s a lot of sand so your best bet is to buy it in bulk at the local landscaping supply or ready-mix supplier.Titebond Sandbox-7
