Trylon is a craft supply company located in the United Kingdom. One of their products is moulding latex, which is a liquid rubber compound used to make moulds of small objects for duplication. Once the mould has been made, dozens of copies can be made out of a variety of casting materials (also available through Trylon). Making a mould with latex can be accomplished in two different methods: dipping and brushing. Both methods require the same preparation work.
Fill any holes that pass all the way through the object with modelling clay. These holes must be filled or the latex cannot be removed from the object.
Spray two coats of acrylic enamel spray onto the object to seal it.
Brush a thin coat of hand soap onto the object to serve as a mould release. Allow it to dry.
Hold a small object (such as a chess piece) by its base.
Dip the object into Trylon latex and pull it straight out again.
Set the object onto a piece of cling film and allow the latex coating to dry. Drying can be accelerated with a hair dryer if desired.
Dip the object into the latex again. Allow it to dry and dip a third time.
Allow the final coat of latex to dry.
Lubricate the outer surface of the latex mould with hand soap.
Peel the latex mould off of the object (like pulling a glove off of your hand). The soap helps the latex slide against itself.
Brush a thin coat of Trylon latex onto an object. Leave the bottom uncovered for easy removal.
The coats for this method must be thin. Trylon latex dries through contact with air. If a coat is too thick, the latex forms an outer skin, preventing the latex beneath it from drying.
Allow the latex to dry fully.
Apply nine more coats of latex, allowing each to dry before applying the next.
Brush another coat of latex onto the object. While it is wet, press a piece of cheesecloth onto it. Allow the latex to dry.
Build up a total of 10 layers of latex and cheesecloth onto the mould. The cheesecloth provides additional strength and helps the mould keep its shape.
Allow the mould to dry completely.
Peel the mould off of the original object and trim off the excess cheesecloth.
Avoid getting latex into your hair or clothing. It is very difficult to remove.
