Before You Begin
Whichever colours you choose for the paint and the hardware (e.g., silver, brass, black) is completely up to you, so feel free to get creative with it. You can even make a two-tone sandbox, just make sure you buy a gallon of each paint colour so that you have enough.
Construct the Sandbox
1.1Use a circular saw or a mitre saw to cut the 2x12 boards into two 45" and two 43" pieces.
1.2Use an orbital sander to lightly sand the cuts (or sand them by hand).
1.3Use a drill and 3" wood screws to construct the 2x12s into a square shape. Check that everything is level with a carpenter’s square.
Construct the Doors
2.1Use a mitre saw to cut the pieces for the two doors:
- 8 pieces of 45" 1x6
- 6 pieces of 20" 1x4
- 1 piece of 41" 1x4
2.2Use an orbital sander to lightly sand the cuts (or sand them by hand) so that the surfaces don’t cause splinters.
2.3Set 4 of your 1x6 pieces down side-by-side, perfectly flat and square to one another. Use 1" treated wood screws to attach a 1x4 piece to the top, middle, and bottom of the 1x6 pieces to hold them together. Repeat to make the second door.
2.4Choose one door and attach the 41" board on the same side as the 20" pieces so that half of its length is overlapping. When both doors are closed, this will help reinforce their junction.
2.5Cut two sheets of the geotextile fabric to a size that can cover the sandbox and part of the way up the sides. Use a T-50 staple gun to attach the fabric.
4.1Install the sandbox doors, using two hinges each.
4.2Paint the sandbox in two coats of outdoor paint.
4.3Install a handle on both doors and measure to ensure that they are in the same position.
If you will be placing the sandbox on an uneven surface, like a wooden deck, then make some drainage holes in a plywood sheet and put it under the geotextile fabric at the bottom of the box to keep the sand in.
