Though they are available locally at home improvement stores, I don't
think the spray can foams give you much value ,
in terms of amount of foam per $$
They are useful for small scale projects, but it takes a lot of cans
to fill a large volume.
You can purchase 2 part expanding foams ,
similar material, but in liquid form
you mix the 2 parts in certain ratios .
You must prepare the 'container' ahead of time because this foam
expands rapidly and expands to many many times it's
original volume .
actually, the uncontained area looks very much like bread rising.
It will fill any voids and volumes and in fact will overflow
(Remember the Woody Allen movie "Sleeper", where Woody is the robot
housekeeper?
the scene where the dishwasher overflows with foam and he tries to beat
it back down with a broom?
This could be you (or me) mixing too much foam at a time!)
You can use as much or as little as you need , each time.
You can use a knife, saw or sure form to finish off any overflow
These products are often used by the stagecraft industry and stage set
builders, as well as mixed media artists, etc.
You do need to learn how to handle and use the products safely and
effectively,
also what materials it will and will not release .
It is available in different hardnesses (i.e. rigidity of final foam).
when expanded against plastic for example, the surface will be quite
smooth and you can paint it or coat it with other materials.
you can purchase these and other sculpture and moldmaking materials
from a number of places
one of them is from Douglas and Sturgess

Actually for anyone interested in such materials, the Douglas and
Sturgess catalog is a gem of information.
very drool worthy.
their website also has useful information on casting, etc.

A few months back I tried the builders insulation foam in a can.
Spray your form with WD 40 or any release agent then spray away.
The stuff expands. ...
