attaching a wood cap to a knee wall
Doug
of the knee wall I plan to put a black walnut cap. The knee wall is 2
by 4 construction covered in cement board. The black walnut will be
polyurethaned then attached to the knee subwall. A friend suggested
"gluing" it down with silicone. Any thoughts on that suggestion.
Thanks
Leon

Silicone will hold it but I suggest you not put a wood product that is not
painted that close to a tub or shower as it will be an on going maintenance
problem.

easily removed. Couple of thoughts. Be sure you seal that cap with the
poly all around and be sure it's thoroughly dry before any silicone is
applied to it.
The silicone caulk takes space, think of it as a thick glue so unless you
can apply a lot of weight to the cap while it's curing (30 days) you may
want to do the following. Route a small groove (1/4 wide", 1/8" deep or so)
all around the bottom of the cap. About a 1/2" or so in from the edge or
far enough in so the groove is over solid wood or whatever the cap sits on.
Slightly overfill the groove with silicone and put it in place, wiggle it
around slightly to smear the excess and weigh it down. Now the silicone is
glued to the knee wall and there is a bead of silicone holding the top from
any lateral movement. Doubt anybody would be pulling on it hard enough to
break the seal.

Silicone is a bad joke for this application.
Find a marine chandlery that handles Sika products and get a tube of
SikaFlex 291.
Not sure about the walnut, might want to think teak, the real stuff.
