Canned foam also does not do well when put on thick. There was a TV show
where they tried to use the foam to make a part using a mold where the
material was several inches thick. The next day when they opened the
mold the only foam that set up was on the surface and there was a large
void where the foam had liquified in the middle.
Tim, there are two types of expanding foam in a can, the stuff you used,
and a minimally expanding foam intended for around doors and windows so
things don't get pushed out.
Peace,
Pat
