Introduction Plaster over radiant heat walls is coating heated walls with plaster after adding mesh and a small isolation layer. It relies on a reinforced base and a separating layer to handle heat and movement. In practice, expect this to be a hands-on job that needs careful prep and patience. The work breaks down into
