Action 3: Building the framework

Affix a joist at each end of the ledger implementing angle

brackets or galvanised joist hangers and verify that they are

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

maintain them level.

Fit joist hangers (using galvanised nails or screws in each

gap) alongside the ledger at 400mm (16in) intervals. Join to a further

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

Verify that construction is rectangular and

level at all phases.

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

strengthen and strengthen the platform.

Fit a 2nd joist onto the end joist for additional

strength and join with coach mounting bolts.

Idea: It is practical to use posts on concrete

floor blocks or fence post bases if you

desire to increase the deck.

Action 4: Laying the decking

Decking is the most visible part so take care and

attention to line up all fixings and lay straight with

identical spaces amongst

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

shapes but this reveals more cut ends with problems of

cracking. Always use constant

lengths if possible.

Decking planks with an end grain are ideal. Set this way up for

reduced warping using a pair of galvanised nails,

screws or deck clips at every single joist. Use

purpose produced stainless steel or galvanised screws so that your decking isn't

spoilt by corrosion discolorations.

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

guarantee regular gaps. This is

crucial for

venting and enables for expansion in

rainy conditions.

Suggestion: If any boards need joining, put together on

top of joists.

Action 5: Polishing off

Expand the boards over the sides of the side

joists and trim straight when all are laid. If you would like, use a fine-toothed saw to avoid cracking.

Fix on a facia board to protect the ends - if employing nails, tap

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

Word of advice: Outdoor patio panels

are stress treated with a long-enduring chemical

procedure but the colouring will diminish after a few months.

You can choose to leave your terrace to age

by natural means or treat it with an

outer penetrating oil that soaks right into the

wood rather than resting on the surface. These come

in various timber

hues and can be brushed, sprayed or rollered onto the

planks.
