If your shed has an OPTIONAL TIMBER FLOOR KIT, fit this now.
• Take all 5 x 4000mm Floor Joists and place them parallel (with
the narrow side of the joist on the ground) as per the diagram.
The outside joists are 2000mm apart and the centre 3 joists are
500mm spaces (to the centres).
• Select 2 x 2000mm floorboards and lay them on the top of
the joists, one at each end as per the diagram. Nail the
floorboards to the joists, flush at the corners, with 2 x 50mm
clouts at each end.
•
When completed, Measure
diagonally
from one outside corner
to the other, note the measurement and then measure the opposite
diagonal distance. These measurements must be the same for the
shed to be square. Adjust if necessary.
• Once the shed is square, check that the spacings of the remaining 3 x joists
are 500mm apart to the centres and nail 2 x 50mm clouts through the end
floorboards into each joist at each end.
• Check for square again nail another floor board at each end with 2 x nails into
each joist.

FITTING THE REMAINING FLOORBOARDS
• Next lay all of the floorboards onto the joists. Note, you may
need to cut down a floorboard
lengthwise to fill the final gap
(fig. 1).
• Starting from one end, lay the floorboards in place until you reach the middle of the floor.
Then start fitting them from the other end until you have a gap near the middle of the floor
that the last floor board won’t fit into. If you don’t need to cut one down, move to the final
step on this page.
• When all of the floorboards are in place, measure the width of the remaining gap and add
3-4mm to ensure a tight fit. Cut the board lengthwise to this measurement (fig. 1).
• Remove 2 full floorboards and fit the cut down board (fig.2). Make sure that the ends of all
the boards are straight and aligned with the joists at both ends.
• Place the final 2 boards in place inverted as per fig.3, and align the ends to the rest for
the floor. Stand firmly on the inverted boards to push them into place and tighten all of the
floorboards.
• Finally, nail all of the floor boards to the joists with 2 x nails per board into each joist.
Your floor is now complete and ready for your shed!
