Mineral plaster and its application

Because of its natural composition and longevity, mineral plaster is a popular option for wall finishes on both interior and exterior surfaces. This kind of plaster provides a breathable and environmentally beneficial wall covering option because it is composed of mineral ingredients like lime, cement, and sand.

Mineral plaster has the ability to control moisture, which helps to keep indoor environments healthy and inhibit the growth of mold. This is one of its main advantages. Additionally, it has a high level of weather resistance, which makes it perfect for outdoor applications requiring durable protection.

Although applying mineral plaster takes some skill, with the right tools and methods, it can produce a lovely, textured finish that gives any area character. Knowing how to use mineral plaster correctly can have a big impact on the outcome, whether you’re building a new project or remodeling your house.

Advantages of mineral plaster.

Even though it has disadvantages, occasionally those disadvantages can also be an advantage. Take fast setting, for instance. This plaster binds to the base quickly in contrast to many other options, and it finally hardens in 1-2 days. After application, the primary setting happens in 15 to 20 minutes.

Therefore, work with it should be carried out as quickly as possible. Thanks to this advantage, wall finishing is carried out in the shortest possible time. However, if the master is not sufficiently qualified, everything can end in failure. If the mineral composition is applied in several stages, and not at once, the surface will be uneven with drips, which worsens the appearance of the finished wall.
Another advantage of this type of finishing material is high strength. The strength level is one of the highest, and as a result, in terms of service life, the treated surface will be the most durable if the correct combination of building materials is observed.

The reason for this could be attributed to the porous structure, which instead of weakening when exposed to moisture, becomes stronger. Additionally, it flawlessly fulfills the role of heat insulator and permits air to flow through, something that is nearly impossible with acrylic.

Application for interior work.

For interior plasterboard work, mineral plaster is extremely practical. You can alter the texture of the plaster and it doesn’t need any extra processing. It is most frequently used to draw attention to specific elements, like niches, cornices, or even single walls.

Designers adore it because it makes it very simple to apply a rugged, masculine style to the walls.

Mineral decorative plaster used indoors can be further varnished to intensify color and give the surface a unique sheen. As a result, its strength characteristics are further enhanced, and the requirement for regular wall renovations within the room is decreased.

Application for outdoor work.

Mineral plaster is used for facade work because of its strong resistance to moisture and atmospheric influences. Its longevity has been demonstrated in use.

For facades, mineral plaster endures heat, frost, and daily temperature fluctuations. It also resists most cleaning agents, which is crucial in heavily trafficked cities. External staircases, entrances, and basements are frequently finished with mineral plaster for facades.

Furthermore, it is employed to complete the facade as a whole as well as individual components. Since mineral facade plaster doesn’t burn, it serves as fire protection for surfaces that can catch fire, like chipboard, MDF, and wood.

Use for primary rough work.

It is not practical to use mineral plasters as starting coatings because they are primarily decorative finishing compounds. They are applied to surfaces that have already been prepped, degreased, large differences leveled, and cracks covered. This is because the composition that has been applied will only highlight flaws.

Use for decorative/final work.

For decorative purposes, mineral plaster is far more convenient. In addition to looking really good, it doesn’t require any extra coatings like wallpaper or tiles.

Both tinted and unpainted mineral decorative plaster are available. It is sometimes even applied over a surface that has previously been painted with colored primer. Therefore, the base’s color is maintained when a thin layer of an almost transparent layer is applied, and its depth is obtained by applying a second layer of colorless varnish. Depending on the type, mineral plaster offers a variety of finishing textures. It may be silky, pebbled, or grooved.

For many years, the exterior of houses has been decorated with mineral facade plaster, of which t.n. «fur coat» is a striking example.

Technology of applying plaster, what is necessary for work.

There is no variation in the order in which the steps are executed when applying it. Protective gear is used for work and when applying other types. Since the composition has an alkaline pH, exposed skin areas must be protected. The following are the tools you’ll need:

• Containers for mixing (if a dry mixture is used);
• Construction mixer (optional);
• Spatulas of different sizes;
• Steel float (for applying the composition);
• Trowel;
• Plaster float (for creating texture, optional).

Furthermore, you might require:

• Masking tape;
• Beacons;
• Plaster mesh with screws;
• Corner profiles.

If the walls have visible flaws like holes, cracks, crooked bends, or depressions, they are first leveled using starting compositions. They must be disposed of beforehand.

There might be extra cement mortar after such preparation, which also needs to be disposed of. Medium sandpaper is one of the grinding tools used for this. In addition, the wall needs to be degreased if there are any stains. Plaster mesh needs to be laid if plastering is done over mineral wool insulation or another type of soft base. It is fastened to the ready base, and the top is covered with a mixture of starting plaster.

To increase adhesion, the wall is primed prior to applying the finishing composition. In order to prevent the composition from sticking, water is used to moisten the tools before they start to work. Since a particular area will be covered in one sitting, it is imperative to determine ahead of time how much composition is required to cover it. Any leftover solution will dry up and become unusable for more work.

Should the store-bought ready-made plaster not have a convenient consistency, it can be smoothed out by diluting it with tap water. This is a prerequisite because an uneven mass will result in streaks that exacerbate the appearance. Thick sour cream is thought to have the ideal consistency.

Applying masking tape along the drawn or marked lines allows you to create a geometric pattern or combination of colors on the surface. Both top to bottom and bottom to top applications are possible for the solution. There is a 15-degree angle between the tool and the wall. The layer ought to be thin, not thicker than the composition’s largest portion. Using a spatula, the rough layer is applied first, and then it is leveled. Following their placement on the corners, pressing, and covering with a building mixture, the profiles are leveled.

The next step in processing with a composition like "Bark Beetle" is to create a texture. Based on the intended outcome, a plastic grater is used in either circular or linear motions. After keeping a 15–20 minute technological pause for the primary setting, they remove the masking tape that still has some wet composition residue on it. The surface can be varnished after the last hardening, which takes one to two days, depending on the brand.

Electrical equipment can also be used to apply the composition, but manual leveling of the surface is still required. When working outside, the treated surface needs to be shielded from the wind and debris while it dries.

Made from natural materials like lime, cement, and sand, mineral plaster is a multipurpose and long-lasting wall finish. It is prized for being moisture resistant, breathable, and environmentally friendly, which makes it perfect for both indoor and outdoor uses. This post will discuss the main advantages of mineral plaster, its different varieties, and offer helpful advice on how to apply it correctly for stunning, long-lasting results.

Consumption of mineral plaster per sq. m.

One of the main planning tasks is figuring out how much composition there is per square meter. However, this presents a challenge when it comes to variations in mineral content because you have to be aware of the consumption rate listed on the packaging beforehand. It can be noticeably higher than in other compositions of a similar nature. The applied layer’s thickness is to blame for this. The layer thickness increases with the largest fraction’s grain diameter.

As a result, consumption rises as thickness does. For instance, 3.5 kg will be consumed per 1 m2 of plaster like Barashek, which has granules with a cross-section of 2.5 mm from one of the brands. With the largest granule size of 3.5 mm, the composition from the same manufacturer will already require as much as 4.9 kg per square meter. In contrast, the consumption of textured plaster on a silicone base for interior applications will be less—roughly 2.7 kg.

Use of this plaster in the interior.

Mineral plaster is more frequently used in hotels and office buildings for interior decoration. However, it’s also utilized inside homes, like in the hallway or bathroom. Pebble solutions are a perfect fit for the restroom. Not only does mineral decorative plaster mimic coarse sand, it is also resistant to mold growth.

It is better to use the "Bark beetle" option for hallways, corridors, and stairwells.

It’s crucial to effectively draw attention to the color with extra accessories, like in the example below.

If this isn’t addressed by the style, it’s crucial to avoid going overboard with the details so the space doesn’t appear cluttered.

It is not required to apply a structural plaster composition to the entire space; for instance, you could choose to draw attention to the fireplace alone.

Average cost of mineral plaster.

It’s critical to accurately determine your purchasing power if you wish to purchase mineral plaster from a particular supplier. You must determine the price of each option in order to accomplish this. It is important to keep in mind that mineral-based decorative pebble plaster is significantly more costly than typical cement-based. Even within a single brand, the cost of a 25 kg package varies and is determined by several factors, such as:

• Place of sale;
• Type of mixture;
• Category/grade;
• Region of production;
• Composition of the mixture.

For instance, a bag of Ceresit mixture costs between 597 and 840 rubles, while "Kraysel" and "Teplon" plaster range in price from 450 to 465 and 450 to 518 rubles, respectively. However, there are some instances where the price range—such as "Bolars" from 560 to 2655 rubles or "Vetonit" from 639 to 2500 rubles—can be extremely significant.

For wall finishes on the inside as well as the outside, mineral plaster is a dependable and adaptable option. It’s an environmentally friendly choice because of its natural composition, which consists of materials like sand, cement, and lime. In humid environments, the ability of mineral plaster to breathe aids in moisture regulation and the prevention of mold and mildew.

Applying mineral plaster is comparatively simple, and even a do-it-yourself enthusiast can produce results that look professional with the right tools and techniques. You can alter the texture and finish to fit your style, from sleek surfaces to more textured, rustic appearances. Because of its adaptability, mineral plaster is a preferred material for a variety of architectural designs.

Mineral plaster is renowned for its longevity in addition to its aesthetic and practical qualities. When applied to external walls, it is resistant to severe weather conditions and fading over time. Mineral plaster can last for many years on your walls with the right care.

All things considered, mineral plaster provides a classic solution that blends aesthetics, functionality, and sustainability, whether you’re building a new structure or remodeling an existing one.
