Easy to do Brick Molds
This is a fast, easy way to make some free molds for concrete,
hypertufa, plaster, etc.
First decide what you want to copy. It must be something that
can be painted with Acetone without melting. An example would be
a brick or rock.
Now get some of that blue or pink rigid foam insulation.
Clean your rock and be sure it is dry.
Put your insulation on the table, and next to it put your rock
with the side you want to copy facing up. Paint the rock with
Acetone and VERY quickly place it on the foam. When it has sunk
in an inch or two pull it out.
Wait a while for the foam to harden up, and there is your mold!!
Paint on some mold release (also known as 10w engine oil). Try
not to have any puddles, they will cause holes in the concrete.
You may have to play with this a bit to get the feel of painting
and sinking your rock, but it works!!
