RE: GBlist: ?s on the user friendly foam alternative (Chris Koehn)



Handi-Foam is available at the local home warehouse. I've used it before
and I like it better than some of the other brands. The low expansion is
an advantage, for the following reasons:

- If used around windows and doors, it is much less likely to bow the
frame if the gap is overfilled
- Is easy to 'tool' using an ice cube. Just wait for it to skin over,
then take an ice cube and tool the bead much as you would use your
finger to tool a bead of caulk. Makes a nice smooth finish. If you
overfill slightly you can push the stuff back in with the ice cube. This
is the only way to handle the stuff until it completely hardens; it
sticks to EVERYTHING.
- Injects into small cracks better. The high-expansion stuff is already
expanding by the time it hits the end of the nozzle. The low expansion
foam is still liquid at that point and thus it is easy to work it into
cracks. Just be careful not to overfill the crack.

Another good brand is DAP expanding foam. It is a high-expansion foam
but it is easier to control than other high-expansion varieties.
