Interesting, the acetone wipe works for teak, wonder why not IPE?
Anyway, most of the time I just give the acetone wipe lip service.
The 24 grit surface prep makes up for a lot of sins.<G>
it works ok but the joint is better without it. it is one of the urban
myths of woodworking. one of the mags even tested it and found the
same thing I did the joint was not as strong when it was used. not a
huge difference only a small one.
I can't agree with your conclusion, Steve. I'm not sure which
magazine you're referring to, but if you're talking about epoxy,
there's no better source of information than the Gougeoun Brothers,
makers of West System epoxy.
The West System user manual, generally considered the bible of boat
building and epoxy construction, has this to say on the subject:
"Teak/oily woods - Wipe with acetone 15 minutes before coating.
Solvent removes the oil at the surface and allows epoxy to penetrate.
Be sure solvent has evaporated before coating."
That only makes sense. You're only concerned with the ~1/16" depth of
wood that will be bonded. You'd mentioned in an earlier post in this
thread that the acetone drew the oils to the surface, and that it was
better to just bond the freshly milled/sanded surface. A freshly
milled surface has as much oil as anywhere in the wood. How could the
acetone increase the oil at the surface? That's saying that the
acetone concentrates the oil somehow, and, well, that just doesn't
happen. Sanding it won't appreciably affect the oil content and is
necessary with or without the acetone.
West also has a new adhesive coming out that deals with this exact
I haven't gotten my hands on any yet, but I plan to test it out
I did an 18x20 deck with Ipe that is now 5-6 years old ....if you want
photos let me know. I did one coat with $50 a gallon specialty
formula and it only lasted a few months. Wife isn't so crazy about
the patina but it still looks great and certainly will last. Never
saw hair-like splinters but for a while the kids did get some in their
feet...this encouraged them to wear shoes anyway. I never sanded it.
Very stable but very very heavy. I will make benches out of 1x4 I
still have (just the seat and back) but if any table top is made it
will be small like a coffee table. A full sized deck table top would
probably weigh enough that your bracing underneath would be too
expensive. I seek an outdoor stain and poly that will keep the
color...I think I ran across one once.
