Ready to Use: Kem-Ex-It Plus

Ready to use without dilution or mixing, Kem-Ex-It Plus rust remover is an ideal product for getting rid of rust lingering on steel forms, avoiding damage caused by sandblasters and other harsh cleaning methods. Through a chemical reaction, Kem-Ex-It Plus breaks down and softens rust buildup until it is ready for easy removal by a power washer. After removal, steel surfaces are left with a protective barrier that temporarily guards against flash rusting.

Kem-Ex-It Plus also removes concrete and mortar buildup on forms, equipment and tools. Additionally, Kem-Ex-It Plus contains a powerful detergent that cuts through form oil residue on steel and aluminum surfaces. Finally, all residue easily washes away with water.

When applied using Nox-Crete’s Pump Foamer, Kem-Ex-It Plus produces a thick foam that clings to vertical and overhead surfaces for exceptional effectiveness. Use with Neutralizer to eliminate flash rusting caused by chlorinated water during the rinse cycle.
