The desire to decorate the habitat is peculiar not only to man, but only homo sapiens can transform utilitarian things into objects of art. Such a metamorphosis occurred with stucco. Initially, it was made from burnt lime and water and was used to eliminate defects on various surfaces, level them and protect them from external influences. Over time, the plastic mass underwent changes and became a real godsend for decorative walls and ceilings, allowing you to create unique samples of design art.
One of the types of this material was structural plaster, consisting of a base, plasticizers, pigments and special additives in the form of pieces of quartz, wood fibers, particles of mica or small stones. Depending on the main component, mineral, acrylic and
silicone plasters are distinguished
. They are characterized by various properties and are intended for registration of both external and internal surfaces of buildings. Water-based mixtures are odorless and are used for decoration of residential premises, and those made with the help of solvents are used for application on the facades of structures.
Characteristics and performance
A mixture based on cement and lime increases the refractory properties of the surface and its breathability, due to which the decorative layer does not accumulate moisture and does not crack over time. The material, which includes acrylic, is resistant to weathering and does not deteriorate under sharp temperature changes. Latex structural plaster repels dirt and liquid, it can be used in rooms where humidity indicators exceed the norm. Adding special modifying substances determines the properties that characterize plaster. The structural surface also depends on the type and size of the granules.
Methods for applying structural plaster
Before applying the finishing layer, careful alignment of the walls is not required , you only need to eliminate the largest defects and indentations exceeding the size of the granules. So that in the future when changing the design of the room there are no problems with the removal of the decorative layer, it is advisable to paste the surface with special wallpaper or paper. If the coating is applied for a long time, then it will be enough to clean the walls, treat them with a certain primer (depending on the type of base) and dry.
Structural plaster is used for exterior and interior decoration of structures made of brick, concrete, drywall, asbestos cement and other materials. It is sold in the form of a solution that you only need to mix thoroughly, and then it can be applied to the prepared surface. Finishing work is carried out in several stages. First, you should apply the first layer of the mixture with a stainless steel spatula or spray gun, evenly distributing it along the wall. When it dries, the surface is covered with a plastic mixture a second time and treated with a structural roller. Under the influence of air, structural plaster hardens and forms a durable breathable film. Finishing work should not be carried out when exposed to direct sunlight, and the air temperature is lower than recommended by the material manufacturer.
The decorative effect is obtained through the use of mixtures of various colors and surface treatment with a
structural roller.Decorative structural plaster can be painted with special pigments in the manufacture of the solution or with water-based paints after the applied layer has dried.
Combining color and texture, you can get unique combinations and embody the most incredible fantasies. This material is appropriate to use for creating interiors of any style: from luxurious Empire to strict minimalism.
