Sorry but our architects has put gypsum it in the spec and he has got heritage to approve it, it’s a grade 2* building and I think he want to get I the job completed on time and can not wait for the normal time lime to set

 

[lucius]

Thats a new one on me best ask the Architect or Heritage its their idea.

i know in states we used to use putty lime and gauging plaster it was very strong gypsum that you gauged in to the lime in a circle on your spot board about 4-1 i seem to remember,lovely to use but takes ages to set hard not to finish but to set i mean week slater you could still put your finger nail in and make a mark.
