Lath seen from the back with white plaster coat oozing through. Lath and plaster is a building process used to finish mainly interior dividing walls and ceilings. It consists of narrow strips of wood which are nailed horizontally across the wall studs or ceiling joists and then coated in plaster.
The first coat is of coarse stuff finished fair with the darby float and scoured. A thin coat of setting stuff is then laid on, and trowelled and brushed smooth. Two-coat work is described as render and set on walls, and lath, plaster and set, or lath, lay and set on laths. Three-coat work is usually specified for high specification work.
Lime plaster was a common building material for wall surfaces in a process known as lath and plaster, whereby a series of wooden strips on a studwork frame was covered with a semi-dry plaster that hardened into a surface. The plaster used in most lath and plaster construction was mainly lime plaster, with a cure time of about a month. To ...
Sawdust can be combined with clay or cement mixtures and used for walls. Such walls are very sturdy and the method effectively recycles any trees needing excavation from the building area. Depending what type of sawdust is used (hardwood is best) the wood chips in the walls absorb moisture and help prevent cracking during freeze and thaw cycles ...
Clay wall plaster exhibited very high deposition velocities and negligible yields. Clay and materials containing clay (e.g. bricks) consume ozone readily, perhaps because of a reaction catalyzed by metals present in the clay. Clay plaster with very high ozone uptake rates, has certain surface roughness, and porosity.
Plaster veneer (American English) or plaster skim (British English) is a construction methodology for surfacing interior walls, by applying a thin layer of plaster over a substrate—typically over specially formulated gypsum board base, similar in nature to drywall.
Rammed earth is both an old and newer take on creating walls, once made by compacting clay soils between planks by hand; nowadays forms and mechanical pneumatic compressors are used. [10] Soil, and especially clay, provides good thermal mass; it is very good at keeping temperatures at a constant level. Homes built with earth tend to be ...
Wattle and daub is a composite building method used for making walls and buildings, in which a woven lattice of wooden strips called "wattle" is "daubed" with a sticky material usually made of some combination of wet soil, clay, sand, and straw. Wattle and daub has been used for at least 6,000 years and is still an important construction method ...
