Types of Plastering: A Comprehensive Guide
Types of Plastering
Plastering is an important step in construction and renovation projects, providing a smooth and durable finish to walls and ceilings. This process involves applying a mixture of cement, sand and water to create a protective and aesthetic surface. However, there are many different types of plastering techniques, each with its own characteristics and applications. In this article, we will explore some of the most common types of plaster used in the construction industry.
Traditional coating:
Traditional plastering, also known as double-layer plastering, is one of the oldest methods used in construction. It involves applying two layers of plaster - a base or scratch-resistant layer and a top coat. The base coat provides strength and rigidity, while the top coat provides a smooth, decorative finish. Traditional plaster is very versatile and can be used for interior and exterior surfaces.
Skim Coating:
Plastering is a technique used to achieve a smooth, flawless finish on walls and ceilings. This involves applying a thin layer of plaster, usually about 2-3 mm thick, directly to the prepared surface. Plaster plaster is ideal for hiding imperfections, such as small cracks or irregularities. It provides a clean canvas for painting or wallpapering.
Venetian plaster:
Venetian plastering, also known as polished plaster, is a decorative plastering technique that originated in ancient Rome. It involves applying several thin layers of plaster, usually made of marble dust or other natural materials, by trowel. Each layer is polished to a high gloss, marble-like finish. Venetian plaster is often used in high-end residential and commercial projects to achieve a luxurious and striking surface.
Gypsum mortar:
Plastering is a technique mainly used for exterior surfaces, such as walls and facades. It involves applying a thick layer of plaster, made up of cement, sand, and lime, to create a durable, weather-resistant finish. Plastered mortars are popular for their ability to provide texture and architectural detail to buildings. It can be customized with different finishes, including smooth, matte or patterned surfaces. Spray plaster:
Spray plastering, also known as machine plastering, is a more modern and effective method than traditional manual plastering. It involves using a plastering machine to apply a pre-mixed plaster mixture directly to the surface. This technique is faster and provides better coverage, making it suitable for larger projects. Spray plaster is commonly used in commercial buildings, but it can also be applied to residential areas.
Gypsum for drywall:
Plaster plaster, also known as plaster putty, is a technique of using gypsum-based plasterboards to create a smooth, even surface. The plasterboard is attached to the frame of the wall or ceiling, after which the joints and screw holes are filled with joint compound. Gypsum plasterboard is a popular choice due to its ease of installation and versatility. It is commonly used in residential and commercial construction.
These are just a few of the many types of plastering techniques used in the construction industry. Each technique has its own advantages and applications, depending on the desired finish, durability and project requirements. Whether you are aiming for a traditional, decorative or functional finish, choosing the right coating is essential to achieving the desired results in your construction or renovation project.
