George Batchelor asks,
I have a sixteen year old home located outside of Atlanta. It is once again time to paint. However, I notice some of the people in the neighborhood have re-sided with HardiPlank and some have painted existing siding. I am told the determining factor when it comes to re-siding vs painting is the swelling of the planks. I currently have Georgia Pacific siding and would like to know what constitutes swelling (i.e. width in inches) so I can make an informed decision.
