Re: Poll - Grooves up or down on decking ? 12Sep 22, 2011 8:28 pm I laid my decking reed-face UP on an arched bridge over a feature pond to avoid it becoming slippery when wet from the fountain, but I have seen it laid both ways on a flat deck Arfur Re: Poll - Grooves up or down on decking ? 13Sep 23, 2011 9:53 am grooves down! Our previous house had grooves up merbau, what a waste. Not only did everything underneath rot through but it was painful to walk on after a while. The boards also had cracks from the nails as well. Definitely go grooves down from now on. Re: Poll - Grooves up or down on decking ? 14Sep 24, 2011 9:46 am There was some guy on the ABC radio this morning talking about decking/pergolas etc... this was one of the questions.... and they guy (not sure who he was) said the grooves should go down.

The grooves are there to stop the decking rotting out where they rest on the joists. So you would be creating a problem, not solving one.

This whole airflow thing is a load of crap - how much air is gonna flow through those piddly little grooves? And how likely is that to stop rot? Not likely at all. If you are that concerned about your joists or boards rotting, then put a primer on the joists or put a physical barrier bewteen the joists and decking boards. Re: Poll - Grooves up or down on decking ? 19Sep 26, 2011 8:22 pm Have had both (grooves up where on house previous to us buying and we add grooves down) And there was a huge difference between the two!!! The grooves up ended up a big eye sore and rotted not to mention that previous owners had painted it and it was really hard to repaint into all those gooves again (not a good look) not to mention all the dog hair that got caught in there Yukko. The gooves down still, to this day looks great, easy to restain, and has nice clean lines.

When you have ripped up as many decks as I have you see the difference. Putting a primer or physical barrier between the joist and the decking board ONLY protects the joist, moisture will still be on the underside of the decking board. Those "piddly little reeds" do make a massive difference. Hi, as per the subject. Does anyone have any recommendations for the best value decking oil (Bunning is close to where I live) for a treated pine deck? Thanks 0 11338 I would really appreciate if if you can complete the poll about windows, if you have a story I would love to hear it. Please share… 0 443 Use a product like Equisol's Vitalise to clean the deck then coat with a penetrating timber oil. It will look 10 years younger and add value to your home. Visit for… 1 15879 |
