Moulding latex is a prevulcanised natural rubber solution having approximately 60% dry rubber content.

Ideal for flexible one-piece moulds, from cold setting resin and Plaster of Paris originals.

Directions:

Plaster models: Immerse the model very slowly (to avoid air traps) into the liquid latex and suspend it there from 20 min to 3 hours depending on the thickness required. Remove coated model and allow to dry.

Other than Plaster Models: If necessary, seal the model with polyurethane varnish and allow to dry. Place item to be moulded on a tray or similar so that excess latex can be contained and returned to the bottle.

Paint latex onto the object one layer at a time allowing each coat to dry completely. Apply sufficient coats relative to the size of the object.

To Thicken Liquid Latex: For heavier moulds, the addition of standard wallpaper paste is suggested.

After applying several coats of unthickened latex, make up a quantity of wallpaper paste 3-4 times thicker than normal. By blending a small amount of this very thick paste with latex, very much higher viscosity latex is achieved which can then be applied to the model.

To ensure a strong mould: Allow to fully set and dry before use. The mould can be made stronger by heating in an oven slowly to 100°C for no more than 20 minutes. Allow to cool.

To Release Mould: Soap the outside of the mould (detergent + water) to act as a lubricant and peel the mould back over itself to release itself from the casting.

Hints:

Avoid air bubbles when brushing latex.

Wash brushes and equipment in warm soapy water.

Avoid contact with petroleum solvents.

Use in a well-ventilated area.

Keep contents airtight for storage.

Store in a cool place.

Ideally use within 60 days of purchase.
