Choice of caulks/sealants?
I know there's a completely bewildering array of caulks, adhesives,
sealants, etc out there on the market but I'm kind of interested
in what the building community prefers these days, and why. I'm
not even sure it's 100% kosher to do brand comparisons here on GBA
but if it's all in the context of *opinions* and real-life
experience, hopefully that's okay.
HD seems to sell more "contractor bulk packs" of certain caulks than
others, notably Alex Plus and Dynaflex 230 and maybe various types of
Liquid Nails. I've used all of these in some small ways but not
really in any kind of shootout situation. I also tried one or two
of the polyurethane-based ones which, aside from being VOC bombs,
seemed much more cantankerous to apply.
In particular I'm interested in hearing experiences from when any
of these products are used as *adhesives*, for example when gluing
rigid foam to other things like basement walls. What works? Foil
face or no? How long does a product take to set to self-holding?
Where's the boundary between "caulk" and "construction adhesive"?
Even within similar product families I've also seen different
characteristics of viscosity, setting time, and final flexibility
from just which color of goop it is. That's just weird, you'd
think that would have nothing to do with it.
