Ezicover Smooth-Coat is specifically formulated as a surface equalizer/primer for interior broad wall paper-faced plasterboard walls and ceilings. Its unique formulation smoothes out minor surface irregularities and textural differences. Correctly applied over paper-faced plasterboard, Smooth-Coat imparts a surface suitable for a Level 5 paint finish requiring minimal sanding, saving time on plastering. Smooth-Prep may also be used over timber and properly prepared, previously painted surfaces. It has been specifically formulated for air-less spray application, but also gives excellent results when applied by roller.
