A clean surface is necessary for proper bonding of the Armor Plate 951. Remove corrosion, dirt, oil and other contaminants. When coating marine surfaces, the surface should be cleaned from the top of the splash zone to two feet below low-tide water level.
Sandblasting works well underwater and is the preferred method for preparing surfaces for the AP 951 application. Oils may be removed with degreasing solvents or detergent. Concrete may be acid etched, sandblasted, or otherwise mechanically cleaned.
When the AP 951 is to be applied between the inner and outer cylinders, or sleeves, of product lines, first flush the space between the cylinders with a salt solution.
