Epoxy Fillers
Epoxy based fillers set harder than standard acrylic, water-based fillers and are therefore more robust and some even offer more flexibility than other fillers when fully cured. The dense consistency of epoxy fillers make them ideal for areas that a 'non-pick' fill is required. Epoxy fillers also have the advantage of being hard and stable enough, when cured, to take sanding, drilling and screwing into should fixings need to be attatched onto the substrate.
