Looking at Revonia’s references, you have probably noticed that the interior walls and some exterior walls are covered with a rough, sometimes striped and mainly white-colored covering material. This is lime plaster. Lime plaster is intended for plastering, filling and leveling of substrates both in outdoor and indoor conditions. It is suitable for use on facades, in dry and wet interiors, and also on walls and ceilings. Suitable substrates are: wooden surfaces covered with reed board, all mineral plasters, limestone and brick surfaces, concrete and stone, gypsum boards with adhesive primer, cement boards and fiberboards. Lime plaster is certainly one of those basic materials that have been used in the construction of almost every traditional old house. So, in the larger picture, lime has a vital role in our traditional building culture. It is also positive that recently lime as a traditional binder has started to be valued and used more and more. Today, lime plaster has become the choice of a conscious person who wants a long life for the house and good health for the residents through a sustainable finish. But what are the advantages of using such material?
Nature-friendly – lime plaster is a natural finishing material. The lime plaster mix consists of natural sands, crushed limestone and high-quality slaked lime. Lime-plastered surfaces are antistatic and do not collect dust, making them suitable for homes with allergies. Unlike synthetic materials that can release harmful chemicals into the air, lime plaster is a non-toxic alternative. It does not emit volatile organic compounds (VOCs) or other hazardous substances that can negatively affect indoor air quality.
Indoor use – lime plaster destroys mold and fungi due to its strong alkaline reaction. Lime is a natural fungicide that, thanks to its strong alkaline reaction, destroys mold and prevents fungi from growing in a damp room. Therefore, lime is well suited for humid and heavily used rooms. For example, cellars where there is no heating or where several different types of products are stored in bulk.
Humidity – lime plaster regulates the humidity in the rooms and stabilizes temperature fluctuations. For this reason, it is the best choice for earth cellars and saunas. In cellars, the recommended humidity is above 75%. However, at times when the cellar is drier, the lime plaster expels excess moisture and thus keeps the air humidity at a high level. The story is a little different with saunas. During the use of the sauna, the lime plaster stores excess moisture and releases it in the days following the sauna evening to ensure a more stable fluctuation of the humidity level. Lime plaster is also a popular choice in Revonia residential buildings. Regardless of the fact that the humidity level in our houses is low and similar to a normal house, lime plaster is a good choice that maintains optimal and stable humidity throughout the year and thus reduces the risk that, for example, wooden parts will crack due to too dry air.
From a construction point of view – such a constant exchange of dry and wet and cold and warm would cause many ordinary paints to crack and the paint would begin to peel off. However, lime plaster is elastic. If the wall expands or shrinks when the temperature changes, this elasticity allows the plaster to play with it and cracks do not appear as quickly. Both ceilings and walls can be covered with lime plaster, and it also hides minor defects on the surfaces – thereby creating a smooth look. If the lime plaster has outlived its lifespan, is dirty or has suffered physical damage, it is also quite easy to refresh it with home remedies. You can read how to update lime plaster HERE! In addition, you can give the lime plaster the color you like.
In addition to its structurally useful properties and good appearance, lime plaster is certainly a very good choice for damp rooms where fresh food is stored, in sauna steam rooms or living rooms where allergy sufferers live or just for people who favor nature-friendly solutions.
