Finishing Your Folding Sliding Doors

Finishing your patio doors before installation

We recommend finishing your unfinished patio doors with a medium or high
build microporous wood coating system. This will be one coat of base stain
and two coats of top coat, in a wood or paint colour of your choice.

All surfaces and edges of the patio doors and frames (even the back)
must be coated with these three coats to adequately protect the
timber and stop moisture getting in. You must also maintain
the finish regularly, to make sure that moisture doesn’t
penetrate into the timber.

Important: Your oak folding patio doors must be finished BEFORE
the door set is installed. If you don’t this will invalidate the guarantee.
We don’t recommend finishing with Danish oil, wax or any finish other
than a medium to high build microporous wood finishing system.

Please note. If you use steel wool, or allow steel or iron
fragments to come into contact with the untreated oak timber,
this may cause oxidisation resulting in black stain.

There is no need to remove the timber from the sill for
pre-finishing underneath as we have already applied a
protective finish. However, the exposed surfaces and
edges will need finishing and regular maintenance.
