MK4A 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 Gable
End Sheets en-
sure they overlap
correctly (fig 1).
The overlap direc-
tion may differ
from cladding de-
tail.

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.
