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!!!
