Building a floor for a backyard storage shed
Once you have all the tools and equipment, proceed to the following steps!
First, clean any debris from the area where you want to build your storage shed. Start laying down five skids on the ground, ensure the base is flush and level, and space the skids every 12″ or 16″ on center in the edge. To ensure the skids are flat and level, you can use a 4-foot or 6-foot leveler and place the level on top of the skids both ways. When laying down the skids, take your time and level each one. Since this will be the foundation, it must be flat and level, and it will make the rest of the building easy.
2nd, start cutting floor joists. If you don’t plan on using your shed for heavy equipment or tools, we recommend you use 2×4 floor joists since they are affordable. If you are planning on using your storage shed for heavier material, we recommend you use 2×6 floor joists for their strength. Cut the floor joists all to the same length and space them out every 16″ on centers. Use galvanized wood screws to screw the joists to the floor using two or three screws. After everything is screwed and secured, start making the subfloor square by measuring from corner to corner and ensuring that it’s the same number.
3rd, once the floor joists are set, you can start by laying down the plywood on the subfloor. Start installing the plywood on the floor’s corner to ensure it’s square. Put a nail on one side of the plywood and make it square on the other side. Use 6d nails, or you can use wood screws when installing the plywood. After you have installed the plywood that is all squared up and plum, lay down another sheet of plywood.
