SURFACE PREPARATION

All surfaces must be clean, dry, sound, and free from dust, oil, rust, or any other contamination.

Metals should be cleaned with a non-oily solvent soaked clean cloth, such as PROSIL CLEANER 1. Excess solvent should be wiped from the surface with a clean dry cloth. When used on remedial work all existing sealant must be removed. In some instances further cleaning or etching maybe required.
