New outdoor garage door frame : creosote ban

[Reynardine]

New untreated timber has been used to contruct a door frame to support an up and over garage door. This wood is exposed to the elements and has already been rained on a few times.

As creosote is now banned, how should I go about painting this timber frame to protect it from the weather ?

Thanks.

for rot and insect protection, use Cuprinol Green. It is a much better preservative than creosote. The green colour shows which surfaces have been treated, and how heavily. If you want to use a clear finish afterwards, use Cuprinol Clear.

It would have been better to treat the timber before assembly. It would then also have been possible to paint the backs with a flexible breathing stain or paint, as well as the showing surfaces.

facing surfaces can be given several flowing coats of Cuprinol with a brush. Surfaces in contact with the ground should be soaked from ten minutes (small bits) to 24 hours (big bits)

See if you can put a plastic bag or kitchen foil round the timber so that the underneath is immersed in the fluid. Any surfaces that you can't or don't treat will let the rot in. The bottoms of the sides wil be most prone to rot, as will any joints that damp can creep into, and bits that water runs down.

After it has dried off (a few days for brush coats, a few weeks for immersion) you can paint or stain it. I like to use those water-based shed and fence stains that leave a waxy, water-repellent film. You need a flexible and breathing finish if you go for paint.
