If a wall of the shed is against a fence or wall and will not be accessible it is worth covering that area in a good quality roofing felt after wood treating it.

Cover in horizontal sections starting at the base and overlapping the next layer up over the layer below to stop water ingress.

If ur going to that extent u'd be better off with a membrane as it will let the timber 'breathe' roofing felt won't.

 

Fpr all waste ol is carcinagenic (and i must admit i would't coat a nice shed in it) it really didnae do plants much harm, i used slap it everywhere when painting the fence as a kid and  had more waste oil over myself and plants than the fence and the plants never bothered

 

Does sandolin/woodsheen etc not put a sort of hard film over the wood almost like varnish??

I like to et wood breathe more which i think it does with ur cresote type things.

I still believe cresote (or waste oil) is the best stuff if u really want to preserve something and aren't to bothered wot it looks like, nowadays roo many folk would rather there fence was a pretty colour for a few years before it rotted whereas in the past everyone just had fences the same colour that lasted.

Like a lot of modern things looks over substance

Used oil can’t be all that carcinogenic as mechanics and fitters are still living to old age. 

How many of you constantly are in contact with your fence or shed after it’s been treated. 

Ill keep using it as it works and has done for decades. I use to work on a crude tar refinery and creosote was a by product. Not the watered down stuff they use on telegraph poles.

Real nasty stuff that would leave Weals and welts on your skin. Not just a pink blemish. Works very well but stinks in the sun. 

On new planes wood I use new clean engine oil and let it soak for a few days in the sun, it soon goes in, then another good coat and thicken the end grain as it soaks more up. I don’t have to worry about rot or water damage, no bugs will eat either.

Products like Creosote and old engine oil are not appropriate in the back garden. Apart from being carcinogenic Creosote is toxic to plants - even the fumes - and used engine oil around the garden? This is the 21st century and suitable products are easily available and don't cost life threatening money so why slap such filthy stuff on a decent building. The reason that barely anyone stocks Creosote these days is because there are much safer and more sanitary products available that are at least as good if not better.

Ducksback is for fences and lasts about 5 years. It's similar to decking oil in that it has a tiny amount of wax to aid protection, but such products are little more than watery emulsion paint.

I stand by my earlier post. Sadolin, which originates from Sweden where they have huge numbers of wooden buildings, has always been the No 1 choice because it lasts for years and years and will protect the wood indefinitely if retreated every 10 or so years. We have some 44 year old wooden window frames on the outhouse and the wood is as sound, strong and healthy looking as the day it was bought.

Sadolines is good advice, all the joinerys I worked in wouldn't use anything else.

My company use to manufacture wood preservatives, under our label and for most of the big name brands as well.

Since solvents were banned from wood treatments, most of the DIY "treatments/stains" are water based and not much better than emulsion paint. Notice they are no longer called wood "preservatives". thats because they don't "preserve", they just colour.

Wood varnishes give the best (legal) protection, most of Sadolin's are varnishes.

All the nasty stuff mentioned , such as waste oil, etc., will give the best protection, but it is "nasty".?

that is why most human preservatives are alchohol based i believe..
