There are different types of plaster materials that may be used dependant on finish and requirements.
Gypsum Plaster
A material that is excavated and heated to 300oF to extract the water to form a powder and then bagged. It is then mixed with water on site to reform as gypsum ready to be applied to walls and ceilings
One Coat Plaster
As it says on the tin, this plaster is commonly used on areas that require a rougher finish (e.g Old buildings) for the effect of a traditional lime plaster or in most cases, used for filling patches and chasings following electricians/plumbers. It can be built up in stages up to 25mm.
Lime Plaster
Limestone is heated to approx. 850oC to produce quicklime. Water is then added to produce slake lime and becomes a putty or can be dried to a white powder. Additional water can be added to produce a paste like material.
It was a common material used on wall and ceiling surfaces of lath (“lath and plaster”) attached to studwork to form a frame. It would be smoothed off but not necessarily to a fine finish. Most commonly used in period properties and older buildings.
Heat Resistant Plaster
A plaster material that is applied primarily to chimney breasts or in hearth areas where stoves and fires are liable to increase the relative temperature. Resistant to 1200oC and used in conjunction with fire resistant board and render, it is the ideal material where the surface requires the look yet the resistance to fire
Application
The plasterer will mix the material in appropriate quantities of plaster and water so as to achieve a creamy, smooth texture. Typically, this is then applied as a base coat to the substrate using a trowel in a sweeping motion to cover the wall. Once this has started to “go off” a second coat is applied which is then smoothed off and floated to leave a flat, smooth surface which will dry to leave the perfect finish for whichever decoration is chosen.
