WRAS Approved range of coloured Polyester Gelcoats. Choose from White, Black, Dove Grey, Bright Blue or Dark Olive. If you require a bespoke colour, choose 'Clear' which may be pigmented to your desired colour.
Gelcoat is not a finishing coat; for fibreglass mould making, it is painted onto moulds/plugs and remains tacky after it cures. Resin and Glass are generally applied on top of the Gelcoat. It forms the hard, smooth shiny surface of the finished article and is usually pigmented.
It paints on easily but does not drain from vertical surfaces. Use Topcoat if a finishing paint is required. WRAS approved.
How to Apply a Brush Polyester Gelcoat
This depends on the type of mould you are trying to make (male or female). In this case, it sounds like you need a gelcoat rather than a topcoat. Please refer to our guide on making a mould which will detail the mould making process.
The expected coverage of the Standard Polyester Topcoat and Gelcoat is 500g per square metre.
