Deck restoration (thinking about deck oil? read this first)

No...I am not going to spend my time disproving your theory based upon glossy 'well written' articles, especially when you admit you are a layman (no bad thing) and so will not understand the principles and mechanisms of fungal decay.


If you wish to disprove that 'BS 8417:2011 + A1:2014 Preservation of wood. Code of practice' is wrong, because it does not consider oil a 'preservative', feel free to do so.

I wasn't asking for much time to be spent, more a basic principle explanation of why oil is so bad. I enjoy talking and helping people out in areas I am knowledgable in as it not only helps them out but I realise it is considerably easier for me to advise than for them to research. Apart from 'it's bad because I say it is bad', there's not a huge amount to go on here.

I understand that being knowledgable on a subject does not make you a teacher so I will thank you for what you have shared and continue my researching outside of this thread.

I think you need to re-read the thread.

Oils may last 18 months but can last as little as six months, once the oil fails the timber can weather, which was exactly what happened as shown in the origonal post.

This seems to mystify you, can't understand why, oil fails = timber weathers?

If you are prepared for the high maintenence, go ahead, most people are not.

Nothing said in this post is new information, so I really can't understand your view that you think I am saying 'its bad because', unless this is some lame attempt at trolling, in which case goodbye.

The picture at the start of the post does not look like oil, it looks more like a water based stain which has broken down and moisture has got underneath. Oils, on a decent surface will soak into the wood, yes they may need several coats but they don't lift like that because they don't sit on the surface like a varnish or water based stain.
Because they soak into the wood there is nothing to lift off the surface.
