The boat builder's preferred keel filler when the keel needs to be filled after, for example, a grounding. Interfill 830 does not absorb water as it is epoxy-based. Interfill 830 is the best alternative for profile filling of the boat, both above and below the waterline. It is a light gray 2-component lightweight epoxy filler that can fill up to 2 cm. per layer, without running. Interfill 830 is easy to sand and is especially suitable for large surfaces.
Can be used both above and below the waterline on steel, aluminum and composite hulls.
