I have an all-wooden 1st floor balcony, about 6x4 ft, where the balcony
floor consists of about 10 narrow wooden planks (separated by thin gaps, not
tongue-and-groove) supported underneath by 4 (much fatter) joists that are
in fact extensions to the joists supporting the 1st floor interior.
Obviously, the joists are at right-angles to the narrow planks, which in
turn are parallel to the wall of the house.
Despite trying to keep everything covered in sadolin, the narrow planks are
mostly rotten. One of the joists is appears partly rotten, but only along
its outer edge, and a carpenter chap (who has since become uncontactable)
assures me that this was originally tree sap, and the "rot" isn't really
rot, it's just insect infestation of where the sap was, and the rest of the
joist is not in any danger of rotting.
So here are a couple of questions for all you woody folk out there:
1. Using a screwdriver, I have vigorously scraped away the infested part of
the joist, leaving about 95% of the original. Is it now just sufficient to
sadolin over the exposed surface, or should I treat it first with
2. What type of wood should I replace the narrow planks with? Because it was
so fiddly to sadolin between them (because of the narrow gaps) ideally I
want fewer but wider planks, also perhaps with a "camber" like a road so
that rainwater runs off 'em (the old narrow planks had no camber). Is this
Thanks a bunch,
