How to rib a vaulted ceiling.

A couple of the EOP team went to Tenby in Pembrokeshire to add ribs to a vaulted hallway.
The property was one of a terrace of 5 decorated within a theme, this one however had lost the ribs at some point in time. The remaining sections around the ceiling roses gave the dimension. Originally these would have been run in situ before the ceiling was skimmed we didn’t have this luxury.

Replacing these was a challenge as the vaulted ceiling had been lime plastered by hand and although the overall look was uniform there transpired to be 4 variations on the curves.
The curves were measured and transferred to our working deck by bending some wooden lath secured with a frame of wood. Back in the EOP workshop we had produced silicone moulds to the dimensions of the ribs as straight sections. This enabled us to cast the ribs with a semi hard plaster and while still soft flop the mould onto it’s side and fit to the exact curve desired.
Once hardened each one could be fitted to it’s individual position and ‘joint ruled’ to run seamlessly into the original elements.

A lot of attention and time taken over the preparation meant that the process could run smoothly and everything could fit.
The final product used modern adapted materials in the process though the final product was the same material to the original satisfying the Conservation Officer to this Grade 2* Welsh town house.
