Action 3: Constructing the platform

Attach a joist at each end of the ledger using angle

mounting brackets or galvanised joist hangers and check that they are

square. Fix boosting slabs at the ends of these joists, to

keep them level.

Fit joist hangers (using galvanised nails or screws in each

gap) along the ledger at 400mm (16in) intervals. Join to a deeper

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

Check that construction is rectangular and

level at all phases.

Nail noggins 400mm (16in) away from each other among the joists to

reinforce and strengthen the assembly.

Fit a second joist on to the end joist for additional

strength and join with coach mounting bolts.

Tip: It is possible to use posts on concrete footings or fence post bases if you

would like to heighten the deck.

Action 4: Laying the decking

Decking is the most visual part so take care to line up all fixings and lay straight with

equal gaps among

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

styles but this exposes more cut ends with problems of

cracking. At all times use continuous

lengths if doable.

Decking boards with an end grain are perfect. Lay this way up for

lessened bending using two galvanised nails,

anchoring screws or deck clips at every single joist. Use

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

spoilt by rust discolorations.

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

guarantee consistent spaces. This is

crucial for

air flow and permits for expansion in

moist conditions.

Tip: If any boards need joining, put together on

top of joists.

Action 5: Finishing

Extend the boards over the sides of the side

joists and cut directly when all are laid. If you want, use a fine-toothed saw to avert breaking.

Fix on a facia panel to handle the ends - if using nails, tap the ends first so they are blunt to prevent splitting the decking.

Word of advice: Deck planks

are tension treated with a long-lasting preservative

procedure but the colouring will change after a few months.

You can choose to leave your deck to age

the natural way or treat it with an

external penetrating lube that soaks into the

timber rather than resting on the outside. These come

in numerous hardwood

hues and can be brushed, dispersed or rollered onto the

boards.
