pouring foam
2 part polyurethane foam is used alot here for sealing drill holes
so heres a few hints.
1 heat up both parts before mixing.
2 give the foam plenty of room to expand .
3 warm the area to be filled to keep it all foaming.
If I was doing a boat I would consider making moulds of the areaes
to be filled from cardboard/scrap wood , line it with plastic pour
the block, trim and fit. any offcuts get thrown into the nextpour.
I would suspect that this would be a lot more expensive than
cutting styrofoam.
I wouldnt pour foam into a confined space as the exit may blockand
solidifybefore it finishes expandingand COOLING. this stuff could
tsart a fire in a tight place
hint for fizzy rdink bottles , place in freezer with lid off , put
on lid when pouring foam , heat of foam will pressurize bottles.
coke bottle rockets!!!!! get a 1 litre GLASS coke bottle in a big
paddock, mix foam in bottle, screw on lid , point into distance and
run away . we have lift off.
Cheers Paul
