Interfill 833 is an easily sandable “lightweight” finish fairing compound for use over the Interfill 830 bare fiberglass or epoxy primer to fill minor surface imperfections.
Interfill 833 can be applied up to 1/4" thick in one application. Interfill 833 mixes extremely easily, trowels out like “butter,” sands with ease, and is perfect for filling pinholes.
Like Interfill 830, Interfill 833 will not shrink or expand and has excellent sag resistance.
Interfill 833 is light gray in color when mixed.
NOTE - Interfill 833 is a 2-part product. You must purchase both the Base and Curing Agent. See Related Products, below.
