Previous | Page: 2 of 4 | Next         Making The Mould (cont.) Sheets of scrim (hessian) are soaked in a thick consistency of plaster. A stronger mix is important at this stage to enable the plaster to hold its shape. The scrim is then laid along the length of the bench inside the profile and wet plaster is applied on top and skimmed to give a nice smooth finish. The horsemould is then run down the length of the straight edge timber which gives us the reverse image of what is being produced. This is then left to set for around 30 minutes. The mould is then cut to length and shellac is applied (varnish) which acts as a waterproof barrier for the mould and the plaster. When the varnish has dried and the mould is ready for the plaster, tallow (a mixture of beef dripping and paraffin) is applied as a release agent. The Casting Process Once the mould has been greased with the tallow, scrim is then cut into sheets and rolled and placed into the cast to form a reinforcement agent. The first coat of plaster is applied to the mould which is liberally splashed with plaster from a brush to give it an uneaven egg shell type appearance. This finished surface allows better adherence for the second coat.   - Products - Manufacturing - The Showroom - Case Studies: - Private Chapel - Midland Hotel, Manchester - Lyall Street, London - Akbars Restaurant
