Filler system

1. Surface preparation

Must always be applied on top of a dry and clean epoxy primer. If overcoating interval is exceeded, the primer should be sanded.

2. Fillers

Jotun Yachting fillers are all two components epoxies, with a mixing ratio ratio is 1:1 both by weight and volume, so it is very easy to get the correct mixing proportion for any quantity needed. Once applied and dry, the filler has to be sanded before re-painting with an epoxy primer or between filler layers. 

NB. All fillers are more porous than epoxy paints, so in case of heavy rain after filler application, they may absorb some humidity. Therefore, it is necessary to let them dry for a couple of days before overcoating in order to help evaporation and drying.
