Siding should be stacked on edge or laid flat on a smooth, level
surface. Edges and corners should be protected from chipping. To ensure
optimum performance, store siding under cover and keep dry prior to
installing. If siding should become wet, allow to dry thoroughly before
installing.
Finish the job by painting Hardiplank with a high quality, exterior
grade, 100% acrylic latex paint which may be sprayed, rolled or brush
applied. Hardie sidings have excellent paint retention qualities that
will keep your siding looking great well after other sidings need
repainting. But remember, paint performance is dependent upon the
quality of paint applied and the conditions under which it is applied.
Always follow the paint manufacturer's written recommendations for
application and maintenance of field applied paints.
