It was then generally superseded by drywall techniques and plasterboard.

Laths ~~are thin strips of wood,~~ typically ~~measuring~~ 25 mm x 6 mm, and positioned about 6 mm apart from each other.	+	The process involved laths (thin strips of timber) nailed to timber joists or posts and then covered with built-up layers of plaster. Laths typically measure 25 mm x 6 mm, and are positioned about 6 mm apart from each other to allow the plaster to penetrate into the gaps between them.

−	~~The~~ three ~~lime putty layers that the~~ plaster would be applied ~~in were as follows~~:	+	Typically three coats of plaster would then be applied:

−	* ~~First~~ ‘render’ layer~~: To~~ fill the gaps between laths ~~and obtain a strong bond~~. ~~Typically~~ about 6 mm thick.	+	* A ‘render’ layer about 6 mm thick to bond to and fill the gaps between the laths.
−	* Second ‘floating’ layer: To provide ~~the~~ smooth ~~finish~~ for the third layer~~. Typically about 6 mm thick~~.	+	* A ‘floating’ layer about 6 mm thick to provide a relatively smooth surface for the third layer.
−	* ~~Third~~ ‘setting’ layer~~: To~~ provide ~~the~~ smooth finish for decoration~~. Typically about 3 mm thick~~.	+	* A ‘setting’ layer about 3 mm thick to provide a completely smooth finish for decoration.

−	The first and second layers typically used a 1:3 lime putty to clean, sharp sand mixture. Animal hair was often added to assist with binding. The mixture for the third layer was usually a 3:1 lime putty to fine sand mixture or lime putty on its own~~. As time went on, gypsum or cement was added which helped to reduce the setting time between layers~~.	+	The first and second layers typically used a 1:3 lime putty to clean, sharp sand mixture.
