• Asphalt shingles should be used between 4x4 runners and blocks or treated lumber. Never use
shingles in direct contact with ground.
• For best results and aiding in water drainage use gravel under each concrete block.
LEVELING METHODS

LEVEL AND SQUARE FLOOR FRAME
Before attaching oor decking, it is important to level and square the oor frame.
A level and square oor frame is required to correctly construct your shed.

Use a level to ensure the frame is level before installing oor panels.
Check for frame squareness by measuring diagonally across corners.
If the measurements are the same, the frame is square.
The diagonal measurement will be approximately 173-1/16" (439,6 cm).
When the frame is level and square, secure one side of frame to the 4x4 runners using one fastener
at ends of each runner. Move to the opposite end of the frame.
Secure the frame to 4x4 runners with one fastener at ends of each runner, making sure the frame remains square
(Fig. A).
After the oor frame is level and square, fasten the frame to the 4x4 runners at each point
where the frame contacts the 4x4 runners.
See page 9 for the preferred oor leveling method.
First, secure
at ends with
one fastener.
