The gelcoat must be mixed homogeneously. It can be heated to approx 40 °C. The optimal processing temperature is between 30 °C – 35 °C. Within these limits, the pot life is shorter, but the material is very easy to spread and can be applied to the pattern without air inclusions. Afterwards, carefully stir in the required amount of hardener. Afterwards, carefully stir in the required amount of hardener. The gelcoat can be applied with a short-hair brush or a spatula (approx. 2.7 kg/m²). If the thickness of the layer should be more than 1 mm, the mixture must be applied several times. Before the second layer can be applied, the first layer must be gelled. After the second layer of surface resin has been applied, it is either immediately sprinkled with ALUMINIUM GRANULATES (2 – 4 mm) (for mechanical bonding of the ALWA MOULD D backfilling compound) or stabilized by an epoxy laminate, epoxy backfilling or epoxy laminating paste.
Layers, which have cured, need to be grinded before continuing. In this case, it is necessary to use a copper layer, for example, of ALWA EPF 10. After curing the surface is easily machinable.
