For standard glass reinforced laminates, weigh the liquids and base in separate clean containers at the following ratio:
AC730 Liquids 1 part by weight
AC730 Base 5 parts by weight
NB. When making a chopped strand premix as described in the ‘casting’ section below, it is possible to work at a ratio of 4.5:1. This ratio should only be used when adding 13mm coarse glass chopped strands. This method results in a high strength pouring mix that is an alternative to a glass reinforced laminate.
If using the mix to brush or spray apply a ‘Gel Coat’ or ‘Mist Coat’ to the mould prior to laminating or use of a premix, the mix should thickened by working at a mixing ratio of 5.25:1. This will help reduce run off or drape on vertical mould surfaces.
In general, the mixture can be adjusted to suit the application or the needs of the end user. Adding a little liquid or base to make fine adjustments is very useful
