I have a new house that's partly clad with Douglas Fir (just over a
half at a guess). The developer said that the cladding would last
about 10 years. I hate to think of the expense to re-clad the house
but I can't believe that if it is looked after it should last a lot
longer. When it was raining yesterday I looked at my cladding which
was getting wet yet my shed treated with cuprinol Duckback just had
the water rolling off it so it got me wondering if there was
something similar which could be applied to my cladding, only I don't
want to change the colour.

On searching I came across this product http://www.valhalco.com/
which to my uninitiated eyes looked like just what I want, however
it's a US company, so no help there. Has anyone any ideas or views
on what I can do to preserve my Douglas Fir cladding? Be kind
because if there is a solution I may just be hiring the Medway
Handiman to come and do it for me!!!

Why not just a clear coat of somethiong like Sadolin?
