SENTRY WOODEN FLOOR
• The optional Sentry kitset wooden floor is precut and designed
to be fitted into the shed after the shed is assembled.
• Assemble shed as per instructions and fit floor last.
(see page 13 for details).
CONCRETE SLAB FOR RAISED BASE PLATE SHED
To build a raised concrete slab for your shed to sit on, we recom-
mend the following:
• The raised slab size should be 15mm smaller than the base
size of the shed and at least 30mm above ground line.
• The slab should be 80mm thick in the middle and 100mm
thick around the edges.
• The slab should be laid on a solid or compacted base.
• Plastic sheeting under slab will prevent moisture coming
through from underneath.
• During construction, you may raise the bottom timber
plate to allow the wall cladding to protrude 20mm below
the bottom plate. This will stop water flowing between
the bottom plate and the concrete floor.
See note on page 8.

RAISED BASE PLATE OPTION
(For sheds placed on a raised concrete floor)
No doubt by now you will have decided what sort of base you are putting down.
Please read the section that applies to your situation.
If you choose to pour a concrete base you will need to decide whether you wish to raise the base plate of your shed.
This allows the cladding to protrude below the surface of the concrete and ensures a water tight pad.
See concrete pad specifications below
By choosing this option you will need to make the concrete pad to the specification below.

ard roof sheets on both sides. Pre drill and fasten with the 50mm roofing
screws provided. Ensure screws are not overtightened as this can damage the
seals and cause the shed to leak.

SECURING SHED
Secure your shed using Treated Timber Pegs or a Bolt Down Kit
TIMBER PEGS—WOODEN FLOOR
• The optional Duratuf Timber Peg Down Kit includes six H5 treated timber
pegs that can be hammered into the ground and then attached to the
Base Plate with stainless steel screws. A Sentry timber floor can then be
fitted on top of the Base Plate if required.
BOLT DOWN KIT—CONCRETE
• The optional Duratuf Bolt Down Kit includes 6 x galvanised
brackets, screws and dynabolts.
• Space the brackets evenly around the shed and fix to the Bottom
Plate and the concrete slab. A 10mm masonry drill bit is required.
IMPORTANT— CLEAN UP
REMOVE ALL DRILL FILINGS FROM ROOF, WALLS AND CHANNELS THOROUGHLY. FAILURE TO DO THIS
WILL RESULT IN CORROSION AND COULD THEREFORE VOID THE WARRANTY.
FIT PADBOLT
• Rivet Padbolt to door and keeper onto Door Jamb as
shown.

FITTING A SENTRY FLOOR KIT (OPTIONAL)
• Position the Floor Joists equally between the side Base
Plates and skew nail each end with two 75mm nails.
• Check that the shed is sitting level and square . Check
that the diagonal Bottom Plate measurements are the
same. This ensures that the shed base is square.
• Place the Floor Boards in position. (You may need to cut
the last Floor Board to the correct width using a Skill
Saw.) Nail each Floor Board in, using two 50mm nails
each end and two nails into each floor joist.
