Hi, we are in the process of renovating our 1700s cottage.
We plan to do a loft conversion in time so want to be efficient in using the suitable materials to meet building regs during the work we do now, but at the same time using traditional materials where possible.
We have taken down artex ceilings on the 1st floor due to asbestos and to expose the original beams and are left with the floorboards to the loft space (which is the same situation with the existing ground floor ceilings being the first-floor floorboards & beams). We plan to insulate and fireboard between the beams to meet a 60min fire-resistant threshold for the future loft flooring, however, we are unsure as to how to proceed with lime plastering the ceiling between the beams.
So far we've gathered the following:
-Seal the beams to prevent water leaching from the lime paster - PVA or DG27??
-Use 60min protection fireboard over the ecotherm/celotex insulation
-Seal/prime the plasterboard for the lime - PVA or DG27 again??
-Lime plaster to prevent cracking - any recommendations on ready-mixed lime plaster that can be applied to plasterboard and in 1-2 fairly thin coats? I've seen Lime Green solo one-coat plaster and Anglia Lime Fibrechalk mentioned on other threads.
Thankyou in advance for any advice or suggestions!
