Polyurethane Foam
Categories: [ DIY ]
I tried to make a block (12x12 cm) of polyurethane foam with a cardboard shape, but what I got was this mushroom full of air and wet on the inside. Moreover, it leaked during the night, so some amount of the PU inside came out, increasing the size of the inner cavity. I'll let it dry a bit before throwing it away, but I'll have to find another way to make my blocks of foam. Maybe making a 6x6 shape out of wook? Note to self: don't fill the shape up to the rim, the foam expands about twofold. Less foam would dry quicklier.
