Skin Coat Casting/Reproduction
Set
the rubber mold back into the mother mold and make sure the locators
are all pushed in place in the mother mold. Then be sure
to spray in Alumilite’s UMR in to the mold. Although
it is not necessary, the UMR will aid in the release and help
to preserve the life expectancy of the mold.
Mix
equal amounts of Alumilite’s Skin Coat Rigid and add a small
amount of orange dye. As soon as you the two liquids come
in contact they will begin to gel. Mix thoroughly for 1 minute
and then begin to spread/paint the Skin Coat into the mold.
Continue
until the entire mold cavity is evenly coated. Try to build
a minimum of 1/16-1/8” thick layer throughout the mold.
An
easy way to build up thickness with out using a ton of Skin Coat
is to brush in a layer of Alumilite’s 610 Foam. The
610 Foam will add reinforcement as well as wall thickness to the
piece. Here we have used approximately 8 oz of A + 8 oz of
B of the 610 Foam with a small amount of Brown Dye. Using
the brown dye in the foam will give the original orange outside
layer a little bit of depth.
Pour
a small amount of the thoroughly mixed 610 Foam along the top edge
and allow it to flow down.
Using
a cheap paint brush (will not be able to salvage), spread the mixed
foam throughout the mold until it is all covered.
Continue
to brush the foam up the walls until it begins to expand. Then
allow the foam to expand and cure.
If
you have thin areas of foam, mix up a smaller second batch and
concentrate brushing the material on the top edge and in the thin
areas. Then allow it to expand and cure.
Once
the 610 Foam has expanded and cured, remove the rubber mold from
the mother mold and prepare to remove your reproduction.
Peel
the rubber mold off of the Skin Coat piece to demold.
You
now have a perfect reproduction of your original.
The
last thing you’ll want to do is to simply trim the flash
off of the edge with sharp knife and you are ready to make your
next piece. Once it is painted and the stem is added, you will
have a beautiful reproduction that will easily withstand outdoor
conditions.
