In modern construction, the surface of the walls is leveled with gypsum plaster, sold as a dry product. The material contains the right proportions of mineral-based components and flexible mineral or organic binders, which contribute to more effective solidification and adhesion to the plane. Traditionally, gypsum plaster is characterized by a high level of whiteness, optimal consistency and an excellent degree of adhesion to the surface.

When can gypsum plaster be used?

Covering walls with gypsum plaster is especially recommended in situations where it is necessary to properly align and prepare surfaces on plasterboards, as well as in cases where it is necessary to obtain a perfectly flat and smooth surface. After that, further treatment of the walls is planned with tools such as interior decoration paint, wallpaper, etc. High-quality gypsum plaster can be used in such works, where there is a need to fill not too large cracks, pits, and to perfectly align too stiff plane segments. It should be remembered that the classic variants of gypsum plaster are best used in a private residential building, including interior spaces that are not susceptible to the harmful effects of excessive moisture. This means that in rooms such as bathroom, kitchen, toilet,it is better to use other building materials.

Benefits of using gypsum plaster

The positive features of gypsum plaster contribute to a significant reduction in the cost of decorative materials that are planned to be used in a further project. The fact is that high-quality material is able to fill in any, even minimal, surface defects (cracks, irregularities of various sizes). Thus, when building materials of this category are applied, for example on walls, a stable, perfectly even surface can be obtained, on which, after some time, a finish such as wallpaper, special paints for interior wall decoration, etc. is applied. Good quality gypsum plaster, has the ability to dry quickly. It is very convenient for repair work in a private apartment building or apartment in a block of flats.

Advantages of gypsum plaster?

Application of gypsum plasterDepending on the functional purpose, special, environmentally friendly and proven softening ingredients with natural mineral origin can be added to the plaster base in various proportions. In addition, the usual gypsum finish includes special polymer additives that are responsible for the resistance of the product to all physical, mechanical and natural external influences. If, when applying, all the recommendations indicated on the packaging are followed, then the product will fulfill its functional purpose for a long time without cracking.

The gypsum plaster is intended for use on walls and ceilings inside buildings, in rooms not exposed to moisture. It is easy to apply and can be sanded. It is used for finishing the substrate of gypsum boards, gypsum plasters, cement-lime plasters, smooth concrete elements, gypsum blocks and cellular concrete. Provides a perfectly smooth surface as a base for paints and other decorative materials. Appropriately selected technical parameters allow to obtain a smooth surface, which is an excellent basis for other works. The simple method of preparing the mass, its plasticity, ease of grinding, as well as other operating parameters make the product very convenient to use and enable quick work at every stage.

Methods of applying gypsum plaster

Mix the contents of the package mechanically or manually with the indicated amount of cold water to obtain a homogeneous mixture and the required consistency. At this stage, you can adjust the texture of the material by adding water or dry material (when filling larger holes, the consistency should be thicker than for smoothing). The mass prepared in accordance with the specified requirements retains its properties for about 1.5 hours. The high quality of the material allows the second layer to be applied to a damp surface in about 30 minutes after the first layer is applied.

The gypsum plaster is evenly applied to the surface, preferably with a stainless steel spatula. The product should be well smoothed during application. The plaster is applied to the walls in stripes from the floor and towards the ceiling, making a movement with the putty knife from the bottom up. The mixture is applied to the ceilings from the window and towards the depth of the room. After drying, small irregularities are removed with sandpaper. The drying time depends on the absorption of the substrate, the ambient temperature and the consistency of the material. When drying, avoid direct solar heating and drafts, and ensure good ventilation of the premises. Further finishing work, such as, for example, painting, wallpapering, begins after the surface has dried.Before painting with water-soluble paints, the finished surface should be primed with a primer recommended by the paint manufacturer or with a diluted paint.
