Surface Preparation

Remove grease, oil, alkali residues and all other deposits. Remove loose rust, rust-scale and deteriorated coatings by scraping and wire brushing. Remove zinc salts with Surfa-Etch 108 Etching Solution. Rinse with clean water. Tight rust scale and mill scale are most effectively removed by abrasive blasting. The surface must be clean and dry during application. Degrease and sand intact coatings to roughen the surface slightly.
