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.
