Fence paint - do more coats last longer?

I would take the 5 year life of Ronseal with a large pinch of salt, it does  actually  say  "up to 5 years".

Our daughter's neighbour has used it on a fence that divides their gardens, and on a bin store he built, after 2 years it has started flaking off.  The panels are rough sawn treated timber, but not sure whether dipped or pressure treated.

She is now treating her side  of the fence with Sadolin, after removing all the flaky Ronseal with a rotating wire brush.  It is a long fence, so not something you want to be doing every 5 years, never mind every 2!

As far as I know, these expensive treatments do also penetrate and help preserve the wood, and the  Sadolin and Jotun products are very similar.

When we fenced our garden some 32 years back, we treated all the pressure treated posts and boards,  before installation, with what was then called Butinox (made by Jotun), and they are, as far as I can see, mostly still in reasonable shape, having had no further treatment.  They are "weathered" but very few have suffered any rotting.

We use the same stuff on the woodwork of the house and only the very exposed parts  need done more often than every 10 years.  The windows round the back that are very sheltered have only needed to be redone once in 30 years.

Just as well, as the stuff is very expensive these days!

My father in law who was a painter and decorator aways vouched that outdoor painting done at the tail end of autumn lasted longer than jobs done earlier in the year, may be similar with fence treatments.

If you have a narrow gap between shed and fence, and any trees nearby, this gap will collect leaves. I guarantee that permanently wet leaves will rot the bottom of shed and fence very quickly. I have now taken to adding a protective layer (either additonal thick, treated wood or something like roofing felt) to protect inaccessible areas.
