[Greenbuilding] Which caulk

[Amy Bauman]

Hello caulkers and potential caulkers -

If greenGoat could add just one caution: please check caulking for the
following possible (asbestos) ingredients:

chrysotile, amosite, crocidolite, tremolite, actinolite and anthophyllite

To provide a little background, asbestos is a term applied to a group of
minerals.  The six minerals listed above are in the asbestos group.  Use of
products that contain these minerals will preclude responsible material
reuse end-of-life.  There's a whole, long sad regulatory tale as to why
asbestos mineral types are still commercially available, and I'm happy to
send our two-pager on that off line.  But trust me ... caulking and joint
compound brands (mostly made in Mexico) may still contain asbestos within,
and this continues to thwart gypsum wallboard recycling efforts nationwide.

Anyway, I thought I'd add a build-for-disassembly slant to the conversation.

Thanks

Titebond has a line of solvent-free and ultra-low VOC caulks and adhesives
(along with low-odor). The solvent-free crystal clear may work best and
cheapest for your application.

Also could consider AFM Safecoat all-purpose caulk.

Depending on your location, they may be hard to find.

I appreciate the discussions on this list about caulking seams to prevent
air infiltration.  We are finishing up the first-floor joists this week, and
while the plumber does the underfloor I would like to spend some quality
time sealing the underfloor seams between foundation and sill, between sill
and rim joist, and in all butt joints.


The question now is---which of the bewildering assortment of caulks should I
use?  The contractor recommends using one with a polyurethane base.  I would
prefer that to acrylic or (ugh) vinyl.  Any recommendations?
