Plastering is the process of applying a smooth and even finish to walls, ceilings, and other surfaces in a building. It involves the use of various materials, such as plaster, sand and cement, and plasterboard, to achieve a polished and uniform surface ready for painting or wallpapering For interior walls, a plaster finish can be achieved through either a float and set method or a skim plaster finish. The float and set approach involves applying a base coat of plaster or sand and cement, followed by a top coat of finish plaster to achieve a smooth surface suitable for decoration.
Float and set can help to correct minor imperfections on a wall, resulting in an even and polished finish. Alternatively, finish plaster can be applied directly onto any plasterboard installation, with a thickness typically ranging from 2 to 3mm, creating a surface that is ready for decoration.
Dry lining refers to the application of plasterboard on timber or metal frames, or on plaster 'dabs' for blockwork walls, as a substitute for traditional wet trades such as brick or block or lath and plaster. The term has evolved to encompass internal fit-out work in buildings beyond its original use as a replacement for sand and cement or wet plaster finishes on internal blockwork.
Dry lining is a skilled trade that requires precision, focus, and a high level of workmanship. A popular method of dry lining is dot and dab, which involves applying adhesive in dabs on the wall and sticking the plasterboard onto it, resulting in an easy-to-apply finish.
Non-loadbearing partitions can confidently be constructed using standard metal stud partitions, offering speed and ease of construction for both commercial and domestic applications. These versatile systems can meet a wide range of performance requirements using minimal components, and can be customized with different types of boards to suit specific needs For instance, Standard Wallboard or Plasterboard is commonly used, but Moisture Resistant board can be employed in areas with high humidity, while a Sound or dB board can be utilized for noise reduction, and a Fire board is suitable for areas that require fire resistance. Vapour or Duplex Board can be used for areas requiring vapour control.
Spray plastering, also known as spray rendering or spray application, is a modern method of applying plaster or render onto walls and ceilings. The technique involves using a spray machine to apply a thin layer of plaster or render in a consistent and even manner across the surface.
Spray plastering has become a popular choice for large commercial and residential projects due to its speed and efficiency. The process is relatively quick, and it can cover large areas in a short amount of time compared to traditional plastering methods. The spray machine applies the plaster or render at high pressure, ensuring an even and consistent finish.
Spray plastering can be used for both internal and external applications, depending on the type of plaster or render used. It is a suitable option for a range of surfaces, including brickwork, blockwork, concrete, and plasterboard.
The main advantages of spray plastering include its speed, efficiency, and ability to cover large areas quickly. It is also a cleaner option compared to traditional plastering methods, as there is less mess and waste. Additionally, spray plastering can be used to achieve a range of finishes, including smooth, textured, or patterned designs, depending on the desired aesthetic.
The MF ceiling system is a traditional method of application that can support some degree of loading. It offers versatility as it can accommodate one or more layers of a wide range of boards, depending on the performance required. These boards include Standard Wallboard, Moisture Resistant Board for humid areas, Sound Board for noise reduction, Fire Board for fire resistance, and the complete range of Gyptone Quattro acoustic boards.
The boards are affixed to a lightweight metal framework of MF ceiling channels and MF perimeter channels. The borders often feature a standard wallboard design. The framework is suspended using either strap hangers or angle sections that are fixed to the structural soffit with soffit cleats.
The tapered edge boards can be taped and jointed using Jointing Compounds and Accessories. Alternatively, a 2 to 3mm skim smoothing coat can be applied to achieve a more traditional plaster finish.
Suspended ceilings are commonly used in commercial buildings, such as offices, schools, and hospitals, but they can also be used in residential settings. The flexibility of suspended ceilings means they can be customized to suit a wide range of design needs and performance requirements. A suspended ceiling is a secondary ceiling installed below the primary or structural ceiling of a building. It is typically made up of a metal grid system that is suspended from the structural ceiling using wires or hangers. Ceiling tiles are then placed within the grid system, creating a smooth, level surface.
Suspended ceilings have a range of benefits, including improving acoustic performance, hiding unsightly ceiling fixtures or ductwork, and providing easy access to pipes, wires, and other utilities that may run above the primary ceiling.
The tiles used in suspended ceilings come in a variety of materials, including mineral fiber, metal, plaster, and wood, and they can be finished in various ways, including painted, perforated, or embossed. The tiles can also be removed or replaced without damaging the grid system or the primary ceiling, making maintenance and repair easier.
Tape and jointing is a process that involves covering all joints and screw holes on the plasterboard to create a seamless finish. This can be done by hand or using a machine. The process begins with scrimming the joints using a fibre tape to prevent cracking. Next, joint filler is applied to bed the tape into the joint.
The tape acts as a reinforcement to ensure that the joints remain strong and stable. Two additional coats of filler are then applied to create a smooth and even finish. Once dry, the area is sanded down to perfection, preparing it for decoration.
Recently, the application of tape and jointing has advanced with the introduction of machines that can spray joint cement over the joints, resulting in an even higher standard of finish. This method ensures consistency across the entire surface and can help to save time and effort compared to traditional hand application.
