Step by Step Process to build an outdoor storage box

Step 1: Cutting the plywood

Put on your 3M Tekk protection glasses. This is for your eyes' safety. Measure the plywood as illustrated below using a Miter box or Tape measure. You may have your own dimensioning depending on the size of the box that you want.

Just make sure to have dimensions that will allow you to use one single plywood. This will help you minimize wastage. Then cut the plywood along the measurements using a Table saw or Skil saw.

Step 2: Assembling the panels

The purpose for your box will determine the type of materials you use for assembling. In our case, we will be using 3M marine sealant and nails. The sealant is the best choice because of its weather resistance and strength.

Place the base panel on a surface that is elevated. Make sure that it hangs a little bit from the edge. Apply the bead on the edges. Then attach the other panel along the edge as shown below.

Have someone help you hold it steady. Using the nail gun nail it after every few inches. This will secure the box more firmly. Ensure you cover your ears with the 3M Tekk hearing protectors to protect you from the constant nailing noise.

Repeat the same procedure with the other edges applying the sealant and nailing every time. Caulk all the seams once you're done with the base and the sides. Use 3M Marine sealant to caulk.

Step 3: Adding Reinforcements and Painting

Hold the trims along the edges and mark the measurements. Then cut the trim boards according to the size of both the top, bottom, and sides. Glue the top, bottom, and side trims then nail them.

Apply PVC molding along the edge of the lid to finish up. Then hinge it and nail it onto to the box. You can add 2 1x2" trim boards to the bottom of the lid. This will improve its strength and rigidity.

Use the 3M Wood filler to feel all the nail holes. Then lightly sand the patched places. Use 3M Abrasive sandpaper to sand. Place your box on a drop cloth. Then apply 2 coats of Exterior latex paint.

Finally, screw 4 casters at each bottom corner of the box. Also, attach the galvanized hinges on both the lid and the box. You can paint the inner side of the lid with the color of your choice. There you go!
