![]() Sets – these ‘curls’ of plaster are known as keys and they play a vital mechanical role in securing the plaster Squeezed through and behind the laths locking the plaster to the wall as it The measured spacing is critical and allows plaster to be pushed or Each horizontalĬourse of lath is spaced about 3⁄8 inch (9.5 mm) away from its Wood lath is typically about one inch (2.5 cm) wide by four feet Hardwoods are commonly used such as oak, chestnut and larch. Greater strength and durability due to the split along the natural grain of the Laths can be sawn or riven (split) with the latter providing The technique derives from a more basic historical building method called wattle and daub that’s been used for at least 6000 years. Laths or ‘lathes’ are narrow strips of timber nailed horizontally across the timber stud frame or ceiling joists and then coated in plaster to finish the wall surface. Studwork is comprised of ‘plates’ that are fixed on theįloor (bottom plate) and ceiling (top plate), ‘studs’ are the vertical supportsīetween the two plates, and ‘noggins’ are horizontal pieces of timber nailed Non-loadbearing walls were constructed using a timber stud frame or ‘studwork’. Loadbearing walls were constructed of solid brick or stone and internal and ![]() Onto hard surfaces, such as brick and stone walls or plaster onto laths, strips In period homes with the plasterwork generally attached in two ways – plaster Lime plaster was traditionally used to finish wall surfaces Was superseded by modern gypsum plaster and plasterboard. Interior walls and ceilings from the 1700s to the early-to-mid 1900s before it The lath and plaster technique was generally used to finish But what is this building method? Why is it no longer in widespread use? And should we worry about preserving it as a heritage feature? Or is it simply out with the old and in with the new? And the whole point of gyprock is to have the smoothest possible finish for painting.Ī good painter can find it very hard to make up for a rough wall.Out with the old and in with the new? Should we keep lath and plaster or replace with modern plasterboard?ĭo you live in a period house? Perhaps it’s Edwardian era, Victorian or Georgian? If you do, you’ll likely have come across lath and plaster construction. DIY can be fun, but the right product and technique is important – for example in settings that experience moisture and humidity problems. We are familiar with the variations in Plasterboard and where they are best used. There are variations to this process and materials used which can result in gyprock sheets that can be used for soundproofing or have water-resistant properties.Īt SY Plastering, we have many years of experience with plasterboard on jobs all over Brisbane and Queensland. Standard plasterboard is manufactured by sandwiching a gypsum plaster layer between two very thick sheets of specialised paper. This new form of plaster grew in popularity because it could speed up the building process. Further advances followed in making the product less brittle and easier to handle. ![]() Unlike the lime-based plaster that was applied wet, it was found that gypsum-based plasters that had a faster drying time for manufacturing the plaster boards, and that is where the name Gyprock comes from.Ī USA company made further improvements to the products’ fire resistance and called their product Sheetrock. These sheets of board provided a smooth finish for painting (or further plaster), as well as insulation, and were faster and easier to put up.The plaster was already dry, between the layers of paper, hence the term Drywall. Even up until the 1940s, most Australian homes had timber nailed across the frame and then covered in plaster (lath and plaster) to provide a smooth finish for painting.īut a process was invented in 1894 of setting a layer of gypsum plaster between layers of felt paper that was called Plasterboard. Ancient Egyptian tombs feature paintings on the plaster walls that line their interiors as did the Romans buildings. Gyprock is also known as gypsum board, drywall, or plasterboard.įor thousands of years, plaster made from lime, sand, animal hair and other ingredients was used to create a smooth interior finish on building walls and ceilings.
