Kneadatite A/B Epoxy Putty BarsKneadatite A/B is a two-part, non-shrinking, general-purpose epoxy putty for interior and exterior maintenance and repairs. It bonds to many metals, glass, ceramics, wood and concrete and is resistant to many chemicals. After mixing and before hardening Kneadatite A/B can be shaped, molded and sculpted as desired.

How to use:

To achieve optimum adhesion, repair surfaces should be scuffed and/or lightly sanded and cleaned free of grease or dirt prior to application. Wear impermeable gloves when handling or mixing uncured material.

Place A and B bars side by side and cut off equal amounts. Remove protective film and blend or knead with gloved fingers until material is a uniform color. Use damp fingers or tools to create a slippery feel for manipulation of the uncured material. Apply to repair surface within 20 minutes of mixing. Kneadatite A/B has a 45 to 60 minute worklife. After 90 minutes it will harden and form a tenacious bond. Functional cure occurs in 24 hours when it can be drilled, tapped, filed, machined and painted. Cured color is off-white. Kneadatite A/B is not intended for structural applications.
