Hello, my name is Scott Compton of Scott Compton Builder. I have enstalled a tremendous amount of cement siding both Hardie and Certainteed, primed and finished paint from the factory. This product can not get wet prior to installation or you will get a white chaulky film on the finished side they call "effervesce". It is my professional opinion to install cement siding with finished paint from factory, colored caulking provided, and one coat applied in the field either after installation or shortly after. I would be more than happy to provide you an estimate. I can be contacted at 603-279-1029 and you can also check my website out at
