Need advices about pourable foam

[jfblouin]

I just buy 2 parts pourable foam for my boat. My seller dont really know how to use it.

What is your suggestions?

Can I heat part A and part B up to 100F before mixing them to have better expansion?

What is the best quantity for mixing part A and B?

What kind of pot and mixing device are best for mixing?

Do you have special hints?

I'm affraid to use this product!!!

That's okay! My french is so embarassing I won't even try here.

Who makes the foam you bought? It would be easy to find out how much to mix if I knew the name.
Heating the foam is a bad idea.
Having a warm workpiece is a good idea.
Use Golves!
Don't breathe it!! Modzeee!!! DON"T BREATHE IT IN!!!! They KILL RATS with this stuff. Do it outside! It stinks!!!Like dead fish!!!
Don't get it on you!!
You can mix it in anything. You have to pour it right away anyway. I'd use a coffee can and some old soup cans.

In what part of the boat are you using this stuff?
You know that anything other than polystyrene foam (Styrofoam) will absorb moisture and turn into a big sponge. I wouldn't use it anyplace below the waterline! I would think hard about it's use at all, certainly NOT in any large quanitys.
There are several densitys of polyurethane (pourable) foam. none of it has a very good "flotation" to weight ratio. It adds weight, holds moisture & promotes rot & corrosion. Be careful in it's use in a marine enviroment. Darn, huh!... and it's SO damn convienent & appears to be the answer to so many design areas. NOPE, sorry.

I have seen some saturation tests with a newer urethane formulation. It looks pretty good. The saturation test was a 48hr test though.

Lets hold good wishes for the new stuff because a "pourable" marine spec foam would be great. Sadly, I learned about this type the hard way a few years back.
