Primer SystemLIFESPAN’s factory-applied two-coat alkyd primer system further protects against water infiltration and weathering. The first full primer coat provides deep penetration and high film build to provide water repellence and to limit cracking. The second primer coat acts as an undercoat, providing a smooth, even, defect-free surface, concealing fingerjoints. The primers used in LIFESPAN are supplied by PPG Industries. |
