Decorative plaster: types and features
Decorative plaster is an interesting, stylish and modern design of the walls. And if you decide to use it, then consider the main types of coating, their features, as well as the rules of application.
Decorative plaster: the pros and cons (video)
If you still doubt the application of decorative plaster, then weigh the pros and cons to make the final and correct decision.
We should start with the advantages of the material, and there are many more than minuses:
- Such material is suitable for both internal and external decoration, with its help it is possible to design both the interior of the house and its exterior. On this topic, coverage can be called universal.
- Decorative plaster performs two functions at once, creating the main coating, as well as completing the finishing finish.
- The plasticity of the material allows you to eliminate and mask the defects present on the surface of the walls. Mass easily fills cracks and grooves, hides irregularities, forming an almost perfectly smooth coating.
- The possibility of applying the material on a variety of surfaces, including concrete, plasterboard, wood and even brick walls. In addition, the application does not require complex preparation, because the pre-level the surface is not necessary.
- The coating “breathes” perfectly, that is, it lets in air and evaporates water, which ensures and maintains natural circulation in the house, and also significantly improves the microclimate.
- Plaster practically does not absorb foreign odors, so it can even be used for kitchen decoration.
- You can not just decorate the walls, but also create an unusual, unique and even exclusive coating, if you choose your method of application and achieve the effect of a relief texture. And some techniques allow you to simulate various surfaces, for example, fabric, stone, metals and even skin, including exotic animals.
- Decorative plaster can organically fit into the interior, decorated in almost any style, because there are several types of coating, the output of different surfaces and colors. The material is used for decoration of rooms, designed in such directions as high-tech, classic, minimalism, Provence, modern, chalet and many others.
- The coating has excellent sound insulation characteristics, as it retains and absorbs noise.
- Decorative plaster is a completely safe and environmentally friendly material that does not emit any harmful substances into the environment.
- The use of this material will provide durability, strength and wear resistance of the coating.
The disadvantages are few and mostly insignificant:
- Quite high cost, especially in comparison with other finishing materials.
- Finishing with the use of this material is a rather long and laborious process. Although complex surface preparation is not required, the composition should be applied to all walls evenly, preferably in two layers. And it can take a lot of time and effort.
- Covered with decorative plaster walls can be contaminated, with some pollution in the structure, literally eats into the surface and greatly spoil its appearance.
- With increased humidity, some characteristics and quality of the material may change, and not for the better.
Material classification by composition and basis
There are different types of decorative plaster, and they differ in such criteria as base, composition, and texture. For a start, it is worth considering the classification by composition of components. The first type is mineral plaster. In her definition of cement, and it forms a durable coating. You are looking at this material in powder form and it requires the addition of water and thorough mixing to a uniform consistency. The cost is low, and the coating «breathes.» But there are drawbacks. So, initially the mineral plaster has a light color, and therefore requires subsequent staining. In addition, the composition is inelastic, which can cause cracking, for example, during house shrinkage or temperature changes.
Acrylic based plaster
Considering the main types of plaster, it is worth noting acrylic, as the basis of containing acrylic resin. And it is this component that determines such characteristics as high elasticity, water resistance, plasticity and uniformity of application, as well as high adhesion (i.e. adhesion) with various mineral bases. Such a plaster is sold in the form of a mass ready for application, it is easily distributed using a conventional trowel.
Using unusual techniques, you can make the surface textured and embossed. In addition, the mass can be given almost any color with tint additives. But the material, firstly, requires additional high-quality preparation of the walls, and secondly, it can ignite, therefore, does not belong to the safe.
Silicone decorative plaster is a modern, relevant and versatile material, produced in finished form and is a plastic mass. As the main component is used silicone resin. The material has several advantages, which include excellent adhesion with any bases, wear resistance, elasticity and ductility, durability, vapor permeability and ensuring complete microcirculation, aesthetics, practicality, resistance to contamination and even self-cleaning, and for external.
The structure is completely ready to use, and drawing will not demand special difficult skills. In addition, silicone plaster is implemented in various ready-made color variations, and their choice is quite rich.
Silicate decorative plaster is made on the basis of the so-called liquid glass and is more suitable for exterior facades, as it can release the fermentation of some harmful substances. The coating is characterized by such characteristics as refractoriness, strength, water resistance, resistance to external influences and temperature extremes.
But the choice of colors is very limited, and since the composition dries quickly and must be evenly distributed over the surface.
If you take an invoice as a basis for the classification, then there are several types:
Finishing decorative plaster with his own hands is carried out in several stages. Responsibilities: first clean and primer. Further plastering follows directly (if necessary, prepare the composition, following the enclosed instructions clearly). It is spread with a spatula or other tool in an even layer. Then you can give relief. Some types are applied in several layers, and the previous one should be completely dry.
After the plaster has completely dried, defects can be eliminated, for example, using ordinary sandpaper or emery cloth. Then, if desired, paint the walls to make them brighter. The use of decorative plaster is a great way to interestingly decorate the walls.
