I tried searching usenet for all variations of the subject, but it
appears I'm the first in internet history to ask this one.
I've got brick on 3 sides, and only 600 square feed of Masonite siding.
Most of that is fine, but down near the ground, where the water
splashes up, it's got a few rotted spots. Searching the web was an
effort in frustration because the siding scheisters have drowned-out
any meaningful search results.
Anyway, I don't want to or need to re-side the whole back of the house,
and I don't really want to remove a 8 foot board to repair a 1/2 inch
on the edge, or even 2 inches on the edge, or one soggy spot near an
overdriven nail head. There was one board on the bottom that was soft
all along the bottom, and I pulled that one off (used recyprocating saw
parallel to the face of the bad board and under the board above to cut
through nails, and used the circular saw to cut vertically through the
bad board, since only 4 of the 12 feet was bad).
But what I want to do is find someone (there must be someone) who has
fixed hardboard lap siding (spot repair), and to learn about their
What I have done works, but it's pretty painful, and I'm not sure how
long it will last. Here's what I did... I scraped the wet/rotted
portion out, then filled it with Elmers wood filler. Since it was a
thick mass of filler, I put shims behind, and wood filler on top of
that. Then, since it was so thick, I waited a long time (days) for it
to dry, then removed excess by using a wood rasp. Then I filled again,
sanded again, filled again, sanded again...well, you get the picture,
it's a pain. If the patch was near the corner board, I caulked it with
GE XST. Otherwise I just painted.
But I figured that someone would have a more efficient technique to
handle the occasional rotten spot on hardboard siding.

There! Now when somebody googles what I tried, they'll at least get my
post, and know they're not the only one!
