How well would this work in making props? I'm working on a bat and tried to make a duct tape mold followed by spraying can foam in. The mold ended up spliting along the seam and being severely misshapen. Is there a way to estimate how much it'll expand?
Not really because the foam will compress in service. Plus you need to be careful as it expands 25 times its original volume and if trapped in narrow slot it would expand and push the transom out of shape. A better method is to dry out the rotten timber and fill it with Bote Cote but it is not something I would recommend due to cost. Nothing beats cutting out the rotten timber and gluing in new Plywood using Bote Cote Epoxy resin thickened with Glue & Filleting filler and either gluing the old inner skin back on or a couple of layers of 435gram Double Bias fibreglass fabric with Bote Cote Epoxy Resin.
Apologies. I thought i had responded to your question whilst I was travelling. Looks like I bombed the course. The pouring foam sets very stiff and not inclined to compress. Once cured it is easy to sand and shape using a sharp knife. Let me know if you want additional info. Dave.
The Foaming Resin does not tend to heat up when it is chemically reacting. The problem is trying to contain it. Be very careful to allow it to expand freely because it can distort and worst case blow out panels. Dave
That has to be the best explanation I've ever seen! Added bonus "Benny Hill theme," I was so waiting for something unexpected to happen.
You're very welcome!
Thanks for the tips. I want to fill boat cabin walls with it;

Can you use that kind of foam for a 5 gallon ac project?
where to buy pouring foam?
Can this be used in transom replacing rotten plywood?

Is the foam soft and squishy enough to make a canoe seat with it?

How hot does it get?

How did you cut the foam
The foam is easy to cut. Small areas use a sharp bladed knife using a sawing action. Als oa normal handsaw works okay or a sharp chisel.
@@TheEpoxyGuruTipsTricks is it able to be sanded?
@@bernardaustin5081 Good Morning Bernard, Yes it can be easily sanded and shaped. Also cuts easily with a saw.
