Last year we had a contractor install Hardie Plank and paint it with the recommened paint. This spring I see where snow was up against the side of the house the paint is bubbling. Is this an issue with improper painting or is this a problem that Hardie Plank has?:(

Hardi needs to be kept from soaking up moisture. You need to keep the snow from piling up against the building. Sounds like you have vapor drive pushing the paint off.

All true
The Hardi isn't failing, the coating is

Could be the coating prep, coating application, or it could be the improper
installation of the Hardi (based on your region...check your local regs.)
