hi all -

i hope this is an ok forum for this - i need your help if you really know your finishes....

i have beautiful tall fir simpson doors, south facing. i wanted to keep the natural wood, so a painter applied 3-5 coats of exterior varethane, water-based to keep the wood light.

after 3 months water at the bottom of the doors (since been corrected) had intruded into the vertical/horizontal grain junction at the bottom and swelled the doors shut. after 9 months the finish had started to peel there and on the horizontal bars of the doors - peeling completely off in little plastic flakes!

is varethane really that lame? what do i do now? can i sand lightly & apply oil-based? if i have to strip, what is the best exterior natural wood finish? oils, wax, ???

help is appreciated since winter's on the way!

You can't put an oil based product over a water based product and anyway if some is peeling it will probably all peel eventually.

Names like Urethane, varathane, varnish are all the same thing if the cleanup is paint thinner - oil based polyurethane.

The best polyurethane finishes for outdoor use is generally considered to be finishes used in the marine industry however if the wood is exposed to sunlight nothing will last very long.

I would consider this - a penetrating stain which does not leave any solids on the surface. The good ones are clear and have a UV inhibitor. They are guaranteed for up to 4 years and when you have to redo there is no stripping involved since it wears out as opposed to peeling.
