Do I have to paint HardiePlank® siding?
Yes, HardiePlank® lap siding must be painted or you may order many James Hardie® products with ColorPlus® Technology. If painting, 100% acrylic topcoats are recommended. Do not paint when wet. For specific recommendations, please refer to JH Technical Bulletin No. S-100 or refer to paint manufacturers specifications. Back rolling is recommended if the siding is sprayed. Within 180 days for primed product and 90 days for unprimed. DO NOT use stain or oil/alkyd base paints on James Hardie® products.
