GELCOAT 5.0 KG GREY This GREY GELCOAT is mainly used with moulds . It is the 1st layer applied to a mould that is then re-enforced with Fibreglass . When then cured laminate is extracted from the mould, it is the outer layer. NOTE - Gelcoat cures TACKY - it should not be used for gelcoat repairs - if you do need to repair a gelcoat surface , we suggest looking for a TOPCOAT ( flowcoat, gelcoat repair ) , Topcoat has a wax additive so will cure touch dry. Using Guidelines : The GELCOAT should be allowed to attain workshop temperature (18ºC-20°C) before use. Stir well by hand, or with a low shear mixer to avoid aeration. It only requires the addition of catalyst to start the curing reaction. The catalyst is should be added at 2% into the GELCOAT .
