It's been a long time between drinks on the deck project with much to report.
1. Better half decided (after talking to family members over the course of about 3 minutes) that yes, we should go composite decking. This despite our constant arguing and disagreement with how "fake" it looks and that we'll definitely be able to maintain merbau. She reneged on that for no logical reason for all the reasons I fought for. The trouble is, I'd already allowed for 19mm of timber when the thinnest composite board at 450mm joist spacing is 23mm. Just going to have to deal with a lip at the entrances.
2. I gave her the task of sourcing the board. This delayed everything a few months.
3. She felt guilty and went to the council for a DA. This stung us because I'd already poured the footings and the bloke came out to inspect the footings. I'm still interested in what exactly he would have confirmed.
Long story short, we were given verbal approval to complete it. Here's a shot from a few days ago, I've nearly laid it all since then:
The product we went with was
NexGEN composite decking. Interestingly the product we received was
Fibreon branded which has different joist spacing recommendations to the NexGEN website. The installation instructions are also BS, which state the ****** hidden clips need to be squeezed together and then screwed from the top using the supplied bit. The supplied bit however is too large for the gap. It also says to NOT screw at an angle, but in my opinion that was the ideal way to do it observing the clip design. I did it anyway and had some spacing issues as I went because the clip would move on the screw - nothing I couldn't address, but has left some larger-than-desired gaps every now and then if you look for them. Reading the Fibreon instructions now however it shows that they should be installed at an angle pulling the clip into the board.
Great.
It cost around $6400 delivered for ~50m2. Not cheap. However, it comes with a 25 year warranty against staining and fading and has excellent resistance to scratching because it's co-extruded (this is me talking, not the salesmen). We got a sample pack of a heap of different products and this was the toughest, along with another brand. I wanted to go Australian made but it didn't offer the same long term benefits and joist spacing of the NexGEN. The other advantage of this stuff is it has two different finishes on each side, so flipping them randomly gives it a more non-uniform and natural appearance. It really does look good once down.
I'm looking forward to some finished shots, but sadly we don't have enough of the edging to go down to the ground. Stuffed that up somehow but I don't really care, I'm happy I've got a surface to walk/sit on that's not dirt.
