Action 3: Building the framework

Connect a joist at each end of the ledger implementing angle

mounting brackets or galvanised joist hangers and verify that they are

rectangular. Fix supporting slabs at the ends of these joists, to

keep them level.

Fit joist hangers (using galvanised nails or screws in every

opening) along the ledger at 400mm (16in) intervals. Join to a further

joist at the other end to develop a supporting beam parallel with the ledger.

Verify that building is square and

level at all stages.

Nail noggins 400mm (16in) apart between the joists to

fortify and support the assembly.

Fit a second joist upon the end joist for further

sturdiness and join with coach mounting bolts.

Tip: It is possible to use posts on concrete

floor foundations or boundary post bases if you

desire to raise the deck.

Action 4: Installing the decking

Decking is the most visible part so take good care to line up all fixings and lay upright with

even spaces between

boards. You can set the decking boards diagonally or in other

forms but this exposes more cut ends with risks of

splitting. Always use steady

lengths if doable.

Decking panels with an end grain are ideal. Lay this way up for

reduced warping using a couple galvanised nails,

anchoring screws or terrace clips at every joist. Use

purpose made stainless steel or galvanised screws so that your decking is not

spoilt by rust staining.

Use 6mm (1/4in) spacers or nails on each individual area of decking panel to

ensure continuous spaces. This is

significant for

ventilation and permits for expansion in

rainy weather condition.

Suggestion: If any boards need joining, put together on

top of joists.

Action 5: Polishing off

Extend the panels over the edges of the side

joists and trim directly when all are inserted. If you really

want, use a fine-toothed saw to avoid breaking.

Fix on a facia panel to handle the ends - if employing nails, tap

into the ends first so they are blunt to prevent splitting the decking.

Tip: Patio boards

are stress treated with a long-enduring chemical

procedure but the coloring will fade after a few months.

You can sometimes leave your terrace to age

naturally or treat it with an

external penetrating lube that soaks into the

wood rather than resting on the outside. These come

in various wood

gradations and can be brushed, sprayed or rollered onto the

boards.
