Part A of foam hardened in the jug

Post by Dutch1 » Wed Jul 10, 2019 11:10 am

Has anyone experienced this issue? I had about a third of a gallon of part a harden up in the jug and it's only a year old. What could have caused this?

Putting part b in part a? :lol:

That stinks. Hopefully this isn't a recurring pattern with the formulation. I know several of us had problems with the foam shrinking. :(

Did you try soaking the jug in a tub of hot water?

High moisture and my foam states it is only good for 6 months after opening.

Oxygen in the air and moisture.

Had to chuckle at that.

High moisture is very possible here.... My jugs don't say anything about an expiration date. I ended up sticking a big paint stirrer through the hard part and getting to good part A below. Then shook it like it owed me money. All the pieces ended up being very small with a good amount of part A left. I mixed two batches and it worked fine. I let the little clumps join the mix if they fell in and they seemed to break up more once I mixed the two parts together. This effort was for a last minute thing anyway. I'm going to let it sit tonight to see if it shrinks at all. If it does, I'll remove it.

I'll follow-up and post the results so everyone knows.

Thanks for the responses!!

I think I read it in my data sheet that came with my foam.

Hey folks. Just to follow-up. I sanded it down to shape about 4 hours after I poured it. May have been too soon. I know, I was in a hurry though. I left it overnight and did notice it fell some the next day but ended up leaving it for the project. It did shrink some but think it will be fine.

I knew I was taking a chance using it since part A was in question. I like testing the limits and you never know unless you try!!

I thought I read to leave 48 hours. :doh: I think 4 hours was a bit quick. :wink:

I've had issues with this foam shrinking after a time (weeks later) on two different boats. It was the same batch of A/B though.
