September 14, 20251 yr We are in the process of renovating an 1820s townhouse. Having a nightmare trying to line up a lime plasterer. Front elevation is double skin brick without a cavity, facing pretty much due South. What would be the consequences of going down the gypsum route for the internal plaster? We’ve managed to safe the original lime on almost all of the other external walls.
