Kneadatite A/B is a two-part non-shrinking epoxy patching putty. Kneadatite A/B is great for larger repairs. It has a long worklife and it smooths out very easily when you add water. The mixed epoxy sets in 50 minutes and can be drilled, tapped, filed, machined and painted. Will cure underwater. Cured color is off-white. Kneadatite A/B is packaged in a 1 lb. kit (1/2 pound Part A and 1/2 pound Part B).
