Nox-Crete's Kem-Ex-It Plus features a chemically active formulation that easily removes existing rust on steel forms. Once the effervescent action of Kem-Ex-It Plus has stopped, remove the rust residue and any unreacted Kem-Ex-It Plus with water. Once the forms are dry, spray apply a liberal coat of Formgard TJ over all exposed steel surfaces. Formgard TJ forms a tough, wax-like film on the form surface that will prevent the formation of rust on steel forms stored outside for up to 6 months.
Our company is in the precast concrete business. We have a problem with the formation of rust on our steel forms stored outside for short periods of time. How can we quickly and cost effectively remove existing rust and prevent the formation of new rust on our idle forms?
