I have purchased the James Hardie Hardipanel Stucco siding and want to attach it to a clock wall. We purchased from a local dealer who really knows nothing about it and I cannot get the answers I need from James Hardie either. We are concerned that you will see the seams as the person on the phone at the local store advised me to use caulking between the sheets. I notice on the spec sheets, they use J-joint type peices and/or caulking. Is there anyone out there who has actually put this on your home and can tell me how to attach it and how to keep the seams from showing and if it is worth the investment. I would appreciate any information I can get at this point. Thanks.
