The Gyprock specialty plaster range provides product options for a range of plastering and casting applications from traditional fibre-reinforced plaster sheet jointing to cast cornices and manufacturing moulds.
Well before Gyprock introduced paper faced plasterboard to the Australian market in 1947, walls were often covered - or plastered - with a plaster mix made from a slurry of lime or gypsum mortar to which a binder such as horsehair or glasswool threads was added for strength.
Later came sheets made of fibre-reinforced plaster, jointed using a plaster mix and cotton or fibreglass tape in much the same way as modern plasterboard sheets but today, more sophisticated jointing materials are used.
Traditional fibre-reinforced plaster sheet walls and ceilings still exist in older built homes and Gyprock has a number of specialty plaster choices for repairs and original style renovations.
In simple terms, a plaster cast is made by pouring a plaster mix into a mould where it sets hard to the three dimensional shape of the mould.
Historically, plaster casts have been used for a multitude of purposes:
Gyprock offers a number of fine, grit free specialty plasters for all types of casting needs.
