Gel Coating

Manufacturing Process: Gel coating

A double layer of gel coat is applied to the surface of the mould.

Gel coat is available is a variety of colours, but in this instance a grey coloured primer gel is
being used as the products are sprayed and baked when finished.

Whilst the gel coat is the first material that is applied to the surface of the mould – which is then backed-up with layers of chopped strand mat, it then becomes the outer surface once the product is released, and hence this is the surface that is seen on completion, therefore it is important not to have any contamination, to try to ensure an even spread, and also to ensure no areas are missed.
