I have an issue with mold in and on my Hemplime walls. The surface seems to be an easy fix I think! What concerns me is the few areas we have mold in the wall. Our plaster flakes off or is crumbing where the mold is concentrated. I have also found some mold in my bales of hemp, not much but discoloration of some of the hurd. This is a test cabin so we can get our recipes figured out and building techniques before we build the main house. We dug out an area that was most problematic. Added a lime paste and some screws to key in the new hemp. My hope is someone out there that has had this problem can help me out.
