I was very keen to find out how to do this as I can see many benefits. I’m already aware of using baking powder to create a light weight and strong bond but this seems like another excellent tip.

Look forward to somebody sharing please

I wondered whether Richard meant foaming PU- brown Gorilla Glue

Maybe, but he also refers to doing the same with ‘pva’ as well.

It is possible to mixx gorilla PU glue with PVA. Its supposedly makes the foamed PU stronger.
I have whisked PU with water to make it foam up more but that make an open brittle foam.
