Decking Oil - Which one for Northern Box

[JasonBF]

Hi All

Now let me start by saying I have done my homework, and I made a decision to buy Spa n Deck after numerous reviews, blogs, posts suggesting it is one of the best.

Well!!! One thing I did not read was the yellow/orange pigment (This has ruined the dark red nature of the timber - only a square metre test, phew)

So, before the timber went down, I coated in Organoil Furniture Oil. This turned the timber into a lovely deep rich red colour, fantastic

I was going to Burnish the oil into the timber, but found that the timber was not completely dry enough. I waited 6 months for the timber to dry out. It has since "greyed" in parts, with a major portion of the decking covered in winter by plastic. That part is still dark red and dried. The other parts suffered the UV problem.

I am now looking at an oil that enriches the red colour (like the Furniture Oil) without a yellow/orange pigment

And Yes I know my maintenance is higher (Every 6 months).

Any Suggestions on oil based products

Eez no possible Jason. The oil must have a tint to keep out any UV. The more tint the less UV. No tint = 100% UV attack. Yellow is at the near opposite to UV, hence the preference to use it.

I've been using Minwax Decking Oil "Natural" and quite like what it does with red timber. Feels excellent to the touch too. It still has a very very slight yellow tint, but works well. Hasn't been down long enough to test longevity (3 months on one deck and 6 weeks on another).

Ok, now see the pictures about the problem I face

The back board is raw (sanded only)

The next one is half Organoil Furniture oil only, half Haymes Decking oil on top of Organoil (Not Bad- might consider)

The third one from the top is Haymes Decking oil only - Partial second coat on the left (Around Screws)

The three boards to the left are all covered in Spa n Deck (To Yellow)

Now you may understand why I like the darker red colour. I am unsure how the 2 oils will mix if I go with Organoil Furniture Oil & Haymes Decking Oil (UV). Perhaps someone with a chemical background may assist with that

The next one is half Organoil Furniture oil only, half Haymes Decking oil on top of Organoil (Not Bad- might consider) This looks to be very similar indeed to what the Minwax would yield.

The three boards to the left are all covered in Spa n Deck (To Yellow) These also look to be to what the Minwax would yield.

Now you may understand why I like the darker red colour. That can really only be remedied by laying more red boards.

I've got a feeling that someone with the chemistry knowledge may say that two different oils may not cross polymerise (at least properly). Probably not at all if they are of substantially different ingredients. The Organoil Outdoor Furn oil is largely Tung Oil IIRC, with a fair hit of Citrene Oil (the predominant and very strong smell). I just had a look at the Minwax can and it doesn't specifically mention anything.

The Haymes looks like it produces more or less the same visual result as the Minwax Natural. I'm afraid you are stuck with needing some tint to mitigate UV attack.

Unless you wish to sand them back significantly once or twice per year......and wind up with wafers

You could always tint whatever product you select.

adding a fair bit of red and a touch of blue will offset the yellow and result in brown ..... the more pigment the better the UV resistance will be.

Universal tinter should do the job, but may be a little opaque.
Solvent bassed stains or dyes might work.
