Claim:
1. A process for manufacturing a trim board, said process comprising: applying a first layer comprising an ultraviolet (UV) curable primer sealer on a front surface of said trim board, wherein said first layer comprising said UV curable primer sealer has a thickness that is 0.05 mm to 0.1 mm; heat drying said first layer in the presence of UV radiation so as to at least partially cure said first layer comprising said UV curable primer sealer; applying a second layer comprising said UV curable primer sealer on a back surface of said trim board, said second layer being thinner than said first layer, wherein said second layer comprising said UV curable primer sealer has a thickness that is 0.01 to 0.05 mm, creating micro-cracks in said UV curable primer sealer of said second layer and providing an increased resistance of said trim board to stresses caused by the weather; and heat drying said second layer in the presence of UV radiation so as to at least partially cure said second layer comprising said UV primer sealer.
