Used CSR Cornice Cement to repair a crack in a fibrous plaster ceiling.
Pushed the plaster up and over the joins and then built the middle up.
Joins in fibrous plaster was done this way when there was a flat roof and was  not possible to get in the roof space  to scrim the ceiling and joins.
The joins were v-cut to about 25mm or 30mm cleated up with temporary battens and maybe if needed a little packing to hold the joins level or just slightly hollow.
The first coat of plaster was pushed up into the join and over the top of either side of the join and and a v-shape put in the middle of the join so it was not  proud.
When set or nearly set the the plaster was cut back level, troweled and polished off.
With CSR Cornice Cornice Cement it is possible to do those two steps in one as it is sticks so much better than the stoppin plaster we used to use.
