Plastering is an essential technique in interior construction that ensures a smooth and even surface. It involves the application of gypsum plaster, which is used both as a base coat and as a finishing coat. Due to gypsum's high moisture-regulating properties, plastering ensures a pleasant indoor climate and is therefore a preferred method in living and working spaces.
Interior plastering relies on plastering because it offers a wide range of design options. Depending on the desired end result, different techniques, grain sizes, and materials can be used to achieve the perfect surface. But what types of plaster are there, and what are their advantages and disadvantages?
Base coat and various types of plaster for plastering work
Before the actual plastering work begins, the base coat is applied. This serves as the foundation for further processing and ensures optimal adhesion of the final plaster. The choice of the right base coat depends on the type of substrate and the desired surface properties. Let's take a closer look at the types of plaster that can be considered as the first step in the plastering process!
White plaster – the ideal base for smooth surfaces
White plaster is probably the best-known and most widely used form of gypsum plaster when it comes to a sophisticated, even finish. It is applied as a fine topcoat and ensures a particularly smooth, homogeneous wall surface. Thanks to its fine texture, it is perfect for rooms where walls are to be painted or wallpapered. Its ease of application and the ability to touch up minor imperfections make it the preferred choice for living rooms, bedrooms, and formal areas.
Lime-gypsum plaster – The optimal solution for damp rooms
The combination of gypsum and lime combines two important properties: gypsum provides a smooth and even surface, while lime naturally regulates humidity. This makes this plaster particularly suitable for damp rooms such as bathrooms or kitchens, as it prevents mold growth and has antibacterial properties. It also improves the indoor climate by absorbing excess moisture and releasing it when the air is dry. This makes it not only functional but also environmentally friendly and healthy for living.
Cement-gypsum plaster – Robust and durable
When it comes to particularly durable wall surfaces, cement-gypsum plaster is the first choice. The addition of cement makes the plaster more resistant to mechanical stress and is particularly suitable for high-traffic interior areas such as hallways, stairwells, or commercial spaces. Its hard, robust surface is also less susceptible to cracks and signs of wear, making it a long-lasting solution for demanding interiors.
Textured plaster – decorative surfaces with character
Those looking for individual design options should opt for textured plaster. Unlike smooth gypsum plasters, textured plaster contains additional grains that create an interesting surface texture. Depending on the technique and material, a variety of effects can be achieved through plastering – from subtle wave patterns to striking structures. Textured plaster is a popular choice, especially in living areas that require a unique look, or in hallways that need to be robust yet stylish.
The role of abrasive grain in plastering work
Another important factor in plastering work is the choice of abrasion grain. This not only influences the appearance and feel of the surface, but also its durability and maintenance requirements. Abrasion grain refers to the size of the mineral or synthetic grains contained in a plaster. Abrasion grains in plastering work can be divided into three categories:
Fine grain (0,5 – 1,0 mm)
Ideal for smooth walls and ceilings that require a particularly elegant appearance. This abrasion grain creates an almost velvety surface. It is often used in living rooms or formal areas and is particularly suitable as a base coat for paint or wallpaper.
Medium grain size (1,5 – 2,0 mm)
It gives the wall a light texture and is less susceptible to minor damage. The medium grain for plastering allows for subtle effects and is particularly suitable for rooms subject to heavy wear, such as hallways or stairwells.
Coarse grain (from 2,5 mm)
Suitable for high-traffic areas, it offers a rustic look. The coarse grain is particularly resistant to wear and scratches, which is why it is often used in commercial spaces.
Choosing the right grit depends on the desired end result and the use of the room. While smooth walls are often preferred in living spaces, textured surfaces can be useful in hallways or stairwells, as they are more robust and less prone to scratches.
Advantages, disadvantages and alternatives to white plaster
White plaster is one of the most popular types of plaster for plastering work, as it creates an exceptionally smooth surface and serves as an optimal base for paint and wallpaper. It also helps regulate humidity, thus improving the indoor climate. Another advantage is the ease of repairing minor damage, which contributes to the longevity of the wall surfaces. However, white plaster also has disadvantages: It is less resistant to mechanical stress and can more quickly show scratches or signs of wear in heavily used areas.
An alternative to white plaster is lime-gypsum plaster. This combines the positive properties of gypsum with the natural advantages of lime. This type of plaster is particularly effective in damp rooms, as it regulates moisture and prevents mold growth. In addition to its healthy living properties, it is also durable and long-lasting.
Those seeking a particularly decorative surface can opt for textured plaster. Different grain sizes allow for individual patterns and textures that are not only visually appealing but also functional. Textured plaster is more resistant to minor impacts and is ideal for high-traffic areas such as hallways or stairwells.
For robust requirements, cement-gypsum plaster is recommended. This mixture is characterized by increased resistance to mechanical stress and can withstand even heavier wear and tear. It offers a durable, low-maintenance solution, particularly in commercial spaces or high-traffic areas.
How does plastering work work?
A professional plastering company follows a precise procedure when plastering to ensure a flawless surface:
- Preparation of the surface: Old paint residues or wallpaper are removed, cracks and unevenness are leveled.
- Applying the base coat: This is selected depending on the wall condition and the desired surface and provides an ideal base.
- Plastering work with the desired type of plaster: Depending on the customer's wishes, white plaster, lime-gypsum plaster or another variant is applied.
- Fine finishing of the surface: The structure is finalized through the use of special tools and techniques.
- Drying phase and final inspection: The plaster must dry completely before further work such as painting or wallpapering can be carried out.
Plastering work for a perfect interior design
Plastering is a proven method for providing interiors with high-quality wall and ceiling surfaces. Choosing the right type of plaster and grit plays a crucial role in meeting both aesthetic and functional requirements. Professional execution by a specialist company ensures that the plaster is durable, smooth, and optimally suited to the space.
