Liquid Latex Rubber (dipping rubber)
Latex  is a natural air drying liquid rubber easily used to produce thin skinned, highly elastic molds.
A former (original model) is simply dipped into the liquid latex. A thin film of latex will cling to the former, and dipping is repeated until a skin of the required thickness is built up.

For “one off’s” or limited production runs, formers can be made from glass, aluminium, glazed porcelain, polyester resin or plaster. Copper, brass, bronze or ferrous formers should not be used as the metals impair the rubber (for the same reason, latex should not be stored in containers made from these materials).
Latex should be stored in airtight containers. A sheet of polythene floated on the surface will prevent the latex skinning.

Immerse the former slowly in the latex, making sure the liquid flows in all dents and undercuts, then remove the former and allow to dry for a few minutes, then repeat the process five or six times to build up a significant thickness.
After dipping, the mold should be left to dry thoroughly before removing from the former. Drying will take about 24 hours at room temp, longer at lower temperatures. Higher temperatures should not be used – if over dried, the latex loses its elasticity.

Once dry, the mould should be rinsed in diluted washing- up liquid, then peeled from the former. Before turning back the right way, dust the mould with French chalk (talc).
Untreated plaster formers should be thoroughly dried before re-use, non-porous formers can be reused immediatel

An excellent new dust respirator, up to 50 times better than no mask, FFP3 is an official rating meaning that this is the best protection achieved by a dust respirator. It is comfy with an excellent fit and a valve. Not all respirators and dust masks are the same, always check the rating to ensure that you recieve the protection need.

Fibreglass chopped strand mat is made up of glass strands randomly laid and held together with a binder, either emulsion bound or powder bound. In the case of Polyester and Vinylester resins an Emulsion bound mat is used and in the case of an Epoxy resin a powder bound mat would be used. The binder would then dissolve in the chosen Resin and this would make the Fibreglass Matt (CSM) conform into the shape of the object being laid up on, most commonly the Glass mat sheets are laid on top of each other in layers combined with a resin to form a thicker / stronger part as part of a GRP (Glass Reinforced Plastic) molding.
