GRP Tooling&Moulding (for Maxim G)

Maxim

First off you need to make a "plug"

In most cases wood is the preffered material.

Once you have a design you can then set about building your plug ( an exact replica of what you want the end product to be)

For this thread i will use a moulding i made for a spray-on tanning boothe............

The next step is to apply a finish to your plug, pattern resin is the best but for quickness yo can spraypaint if the finish is not critical.

This one is pattern resined .........

Then its apply several coats of release wax to ensure the plug does not stick to the mold, once waxed the gelcoat can be brushed on to the plug surface...........

when the gelcoat has cured its ready to fibreglass.....

first layer to go down is a very fine tissue, this prevents the pattern of the fibres showing through the gelcoat....

once cured apply 2 layers matt.

leave to cure fully.....

next process is to bulk the mould up with more matt to the desired thickness(depending on what you are making)

lastly reinforce mold to stop any distortion..........

when your mold is fully cured, it may then be parted from its plug. then the repeat process of waxing, gelling, glassing to make your product............

The wax is not brushed on; it's applied with a cloth, then polished. (a bit like waxing your car)
