Blackbutt Deck, Oil or Stain
Hi, I'm sure this advise has been sort many times before. I live in Sydney and have an uncovered 70sq deck in Blackbutt. 5yrs ago when new I covered in 3 coats of Sikkens Cetol HLS after leaving new wood for 3mths then rough sanding. Didn't last that well so I thought stupidly I could leave deck and let go grey, being hardwood would last 20yrs. I'm wiser now. A bit. I've just spent a week belt sanding back to bare with 40 grade. Replaced a few rottting bits but now ready to cover. Guy in shop says Sikkens was the way to go, but some friends say oil because its not going to crack and chip etc like a stain. I'm now confused. As you can probably tell, maintenance is not my forte. I'm not after a master piece. I deck is for bbq's and drinking and eating food on. Just want longevity without being a slave to it. Any advise from experienced people would be much appreciated
P.S. My railings are treated pine??

Trolling through the forums and internet for days now.
1) Dubious of Stains now.
2)Water Based oils. Its a LIE to start with. Can they be trusted when the label sells a lie. Either its oil or its something water based. Or am I mistaken?
3) What about Intergrain "Nature's Timber Oil™". Except Intergrain website says clean-up in Hot soapy water or mineral turpentine. So is it oil if you can clean up in soapy water? My best pick so far with no one advising me. Love to hear some of your opinions.
4) If I use oil, will the wood turn grey underneath, and what does UV protection mean anyway. Is my deck going to get cancer?

Hi, There's a lot of information available over in the renovate forums. You might have more luck with help if you try over there...

Steer clear, imho. (BTW, all "exterior" products come with half-truths and deceptions, so I've found.)
3) What about Intergrain "Nature's Timber Oil™". Except Intergrain website says clean-up in Hot soapy water or mineral turpentine. So is it oil if you can clean up in soapy water?
The best deck oil I currently know of is Cutek CD50:
Cutek CD50<sup>®</sup> CD50 Index
It penetrates deeper, and lasts longer. But you'll still to recoat every 12 months. It needs 1-2 weeks (at least) between 1st and 2nd coat so that the first can sink in properly. You might need a 3rd coat about a month later.
Cutek is not cheap, and can be a bit difficult to get hold of in Sydney. (I got it from Bristol, Auburn.) You buy a quantity of clear, and also a small tin of tint and mix it yourself. Colours available on the Cutek website.
4) If I use oil, will the wood turn grey underneath, and what does UV protection mean anyway. Is my deck going to get cancer?
And, as Fuzzie mentioned, you can probably get more info (some of it conflicting) over in the Renovate Forums, i.e., the decking forum:
DECKING
I have been through the process of using Feast Watson (old formula), which doesn't last very long even though it's supposed to be a good product. I've also used Spa-n-Deck, but became very frustrated when maintenance time rolled around. Worse, it's really hard to change from Spa-n-Deck to Cutek unless the former is sanded off totally -- else the Cutek seems to react with the remnants of Spa-n-Deck, producing an ugly black colour.
Although Cutek is more expensive and harder to get, I'm pretty sure I'll be using it from now on...

decking in winter
One thing to think about before deciding on the coating is the weather. Would suggest you wait till it is drier. Leave it as it is now and then just give it a light sand when the weather is dry and importantly the timber is dry.
Any oil that is washable in water is not a true oil. Any varnish coatings that seal on top, will most likely require sanding back. The softeners in the coating deteriorate with the sun, the coating splits, and water gets under the cover.
Whilst oils require regular maintenance, this is usually easily done by reapplying another coat, no sanding back required. You know what happens when you sand one too many times....
Now you need to consider what oil and most have a synthetic component in them. Don’t think the pictures that one see with the penetrating powers of Cutek is really penetrating to nearly half the thickness of the boards.......and there is no natural oil that is clear as it breaks down too quickly with the UV rays and weathering.
You need to decide what is your priority, maybe give up your notion of longevity for ease of maintenance.
Oh....and the timber turning black...watch out for mould.Livos Australia

Oils ain't Oils
Thanks for the replies. There is a Bristol in Mona Vale. Will visit and look into Cutek CD50. Website say "Equipment may be cleaned with detergent and water, or mineral turpentine." Cutek does not mention what the product actually is. Stain,Oil??
Cabots Aqua Deck. "Cabot's Aquadeck is a highly durable, low odour decking oil" Also water based.
And yes Angella, Decking in winter. But summer was so wet. I stripped in a week of sun. I cover in plastic when it rains, uncover to continue to dry when its sunny. Didn't think the deck could handle another damp winter.
I keep thinking a deck oil should be oil based. Is there a decking Oil that is made form oil? Is this old fashioned thinking?

Well, I'm old fashioned so I'll throw this out there with the proviso that you wait for someone with more up to date knowledge to comment on my suggestion.
Back in my day.....one of those statements I once swore I would never use.....there was nowhere near the vast choice of products to choose from for coating a deck. You basically has a choice of Sikkens, something called DWD (Doors Windows & Decks) which were both finishes that sat on top of the timber or Sceneys All Purpose Weatherproof Oil.
That was my choice. Didn't last very long....12 months if you were lucky but re-coating was a breeze. And, it was cheap. It dried so fast one could decide to invite people over for a Bar-B-Que, re-coat your deck before lunch and it would be good to go that same evening.
I spotted it at a local hardware store very recently so its still available, but it may well have now been surpassed by one of the newer products that surpasses it in durabilty.
Thus my request to see if that has in fact happened.
I do know it works though. I've seen it on merbou and cypress decks regularly re-coated and many years, and therefore coats....later it still looked a million bucks.
Cheers

Sceneys All Purpose Weatherproof Oil
Thanks Jim, I understand what you mean about not wanting me to take it as up to date advise. I looked up Sceneys All Purpose Weatherproof Oil. Still make it but also make a deck specific oil called "Timber and Decking Oil". Looked at the Data sheet and its Raw Linseed oil, solvents,Alkyd resin and dryers. Sounds like oil.
I will look into this product, Cudek cd50 and my son friends Dad has just recoated his deck with Cabot's Aquadeck, that he says he has been happy with.
I quick clean and an oil/oil type once a year sounds much easier than a barrier type product that if it is breached, you have to strip.

Sounds like you're in the same area of Sydney as me. I have a tiny amount of Cutek left over if you want to come take a look. (PM me if so.)
Bristol, Mona Vale still didn't stock Cutek last time I checked which was quite recently. I really hated the trip over to Auburn, but the main Cutek supplier in Melbourne said they're the closest to me, though this was over 6 months ago. Bristol Mona Vale actually gave me wrong information about it at that time. There's no point asking a supplier about a product they don't stock...
You should probably talk to Cutek Melbourne direct and see if there's a closer distributor to you now.
Website say "Equipment may be cleaned with detergent and water, or mineral turpentine."
But you definitely need turps cleanup. I normally buy a cheap pad from Bunnies and treat it as a single-use item. For cleaning brushes that may be needed at the edges, turps was ok, though Bunnies also sell some ultra-cheap throwaway brushes.
Cutek does not mention what the product actually is. Stain,Oil??
And like I said, the base product is clear. You add tint if you want a colour (which is essential if you don't want the timber to go grey).
Cabots Aqua Deck. "Cabot's Aquadeck is a highly durable, low odour decking oil" Also water based.
I cover in plastic when it rains, uncover to continue to dry when its sunny. Didn't think the deck could handle another damp winter.
I recently Cutek'ed my deck by seizing the sunny days in Winter, so it can certainly be done. (I think it might need a 3rd coat though, since rainwater stopped beading on it after about a month.)

But have you actually done the experiment? I.e., apply Cutek to a piece of decking offcut as per manufacturer's instructions with 1+ weeks between coats, then wait another couple of weeks, then cut it through to determine the depth of penetration? I haven't done this, but... maybe I will now. I vaguely recall a thread over the decking forum where someone had done this and the penetration depth looked reasonable.

I was at Mitre 10 today and FW who were only making the new water based oil have just re released the original "turps wash up Original Formula Classic Finish" in there traditional Decking oil. Make your own mind up on what that means.
Can't find bad things said about Cutek cd50.

New Deck help
Hi there, my hubby and I have just built a new deck made of blackbutt and we love the colour of the timber and are receiving a lot of mixed messages re oil/stain etc We have been recommended Cutek CD50 as well as Sikkens Hlse. Just wondering how your deck turned out and what product you used in the end? We are thinking an oil or something clear w no colour but not sure about maintenance. It isn't a big deck so ok w oiling every 12- 18 months if need be. Any advice is appreciated. Thank you

What about Livos? Noticed they have a deck oil. Have not used any of their products but a lot of people rave about their finishes.
