and two Studs on a flat surface and nail together using two
75mm nails per join. Nail in remaining centre studs using Nogs
to get correct position. Position Nogs centrally between Top
and Bottom Plates and nail in place. (All Plates, Studs and
Nogs are joined together with two 75mm nails each end).

MK4B WALL CLADDING
TO AVIOD CORROSION:
• Where at all possible try not to trap metal filings between two sheets. Remove all metal filings before riveting.
• Carbon in pencils reacts with the Zinc/Aluminium coating on steel. Use ink to mark steel.
TERMS EXPLANATION
• To Tack: To Tack on a wall sheet means to use minimum nails hammered partly in to hold Wall Sheets in position. Should a Wall
Sheet need to be re-positioned, the nails can easily be prized out.
• If a window is required, identify Wall Sheet(s) with window hole pre-cut. Lean up Wall Sheets where window(s) are to be located.
Note:
When fitting Ga-
ble End Sheets
ensure they over-
lap correctly (fig
1).
The overlap di-
rection may differ
from cladding
detail.

MK4B WALL CLADDING
Step 1: Front Wall: Start at the left hand side. Position
the Wall Sheet with the LIP on the left hand
side. Ensuring the LIP is flush with side of the
Stud and the top of the Top Plate, tack in place.
Repeat with Wall Sheet on the right hand side
of doorway.
Step 2: Back Wall: Position the first Wall Sheet with
the LIP on the right hand side. Ensuring the LIP
is flush with the side of the Stud and the top of
the Wall Sheet is flush with the top of the Top
Plate, tack in place. Position the next Wall
Sheet with the LIP on the right hand side. Over-
lap as shown in fig.1 (page 7). Ensuring Wall
Sheet is flush with top of Top Plate, tack in
place. Repeat with remaining two sheets.
Step 4: Nailing Off: Nail one 30mm Clout each side of the Rib (two per Pan) into the Top Plates and Bottom Plates. Nail
Wall Sheets to mid wall Nogs (one per pan). Nail each corner Wall Sheet to Studs using two 30mm Clouts evenly
spaced.
Gable Ends: When nailing Gable Wall Sheets to the Top Plate, use a String Line. At the top of the gable nail two
30mm Clouts into the end of the Ridge Beam. This will stop it from twisting.
Step 3: End Walls: Lean Gable Wall Sheets against
the shed to form gable shape. With the LIP
flush with side of Stud tack in place ensuring
the bottom of the Wall Sheet is 10mm above
the bottom of the Bottom Plate. Tack on re-
maining Wall Sheets. Repeat with other gable
end. If fitting a window, nail in Window Studs
and Nog now. Refer to Window instructions.

MK4B HASP & STAPLE
Using seven rivets, attach hasp to
Left Hand Door and the staple to the
Right Hand Door as shown.
RAISED FLOOR MODIFICATION
For sheds being placed on a purpose built floor,
(concrete, cobbles, ply etc.), the Wall Sheets will pro-
trude 20mm below the Base Plate. This will stop water
flowing in between the Base Plate and Floor.
The Floor should be made 15mm smaller than Base
Size.
Note: Although it is not essential, fitting Damp Proof
Course in between the Base Plate and the Floor
will give added protection against moisture.
CLEAN UP
• Remove all swarf (drill filings) with a soft brush or rag.
• Hose down roof and walls thoroughly.
• For Coloursteel sheds use touch-up paint provided on all nail heads, rivets and exposed cuts.
