SURFACE PREPARATION
The surface must be free of any oils, moisture, rust scale, soil or other contaminants that may interfere with good adhesion. Remove any loose material from seams or other surfaces with a wire brush or scraper. Oil and grease should also be removed with solvents or an appropriate cleaner, such our RoofProtect. In many cases, high pressure water blasts will be sufficient to prepare the surface.

APPLICATION TEMPERATURE
