Plastering is an essential part of finishing walls after they are built. Decorative touches can be added using plaster mouldings. These may be simple and smooth curves or lines, or they may be ornately embellished with ribbons, flowers, or geometric designs. For those wishing a custom finish, skilled plasterers can create plaster mouldings from photographs or drawings, or by examining a piece of moulding and creating changes where necessary. After plaster mouldings are installed, they can be painted to match or contrast with the walls and ceilings.

The most commonly used plaster moulding is the cornice, which finishes a corner where a wall and ceiling join. The most commonly used cornices are smooth and plain, and have a concave, symmetrically curved profile; others may be a plain square block. More ornate cornices may be decorated with straight lines, textures, waves, or patterns. Some have flowers, ribbons or other shapes embossed on them. Cornices are fitted at the top of walls, and hide harsh corners where walls and ceilings meet, making the join appear smooth. Many websites provide pictures of various cornices and other plaster mouldings in Melbourne, showing the decorative designs or a profile of the moulding. These can be found via web searches using appropriate keywords.

Walls and ceilings may be decorated with straps or corner straps, panels or roses. Straps and corner straps are thin strips similar to cornice, but designed to attach to a flat surface. Panels are large rectangles or squares, and roses are round, oval or diamond shaped; they are usually embossed with a design, and are used to decorate large flat areas of a ceiling or wall. Arches can also be finished with plaster mouldings. Different profiles can give an interesting finished to an otherwise plain doorway. Plaster mouldings can be used above square doorways and windows, which can make them appear more regal. Instead of a straight line, plaster mouldings can give a curved or patterned finish, with a decorative surface.

While considered a trade, plastering is also an art form. Plasterers are trained in the mixing and application of plaster, to finish walls and ceilings in houses. Plaster is made up of a mixture of sand, cement, and sometimes lime, mixed with water to create a thick, viscous liquid which can be applied with a trowel or similar implement. Wet plaster is applied to the wall to smooth corners, and conceal joins and imperfections such as nails or screws. After the plaster is dry, it can be sanded and painted. Plaster may also be sculpted in small areas, or poured into moulds to create the mouldings to be used.

Usually, plasterers are also builders, or painters, or both, or may be specialised in plaster only. There are many plasterers in Melbourne willing and able to do plastering in Brighton .A quick web search will give a list of plasterers in Melbourne who do plastering in Brighton and St Kilda.
