Abstract

The bottom of a cement fiberboard article is coated by conveying the article across a gap between a first conveyor and second conveyer and applying a liquid radiation-curable coating system to at least the bottom surface of the article while the article passes over the gap. The coating system is radiation-cured to at least a reduced tack state before the coated surface contacts the second conveyor.
