Types of spray plaster machines

A spray plaster machine is a device that applies a coarse mix of plaster on walls. They are used to reduce the amount of manual labor required and increase the speed of plastering. There are two main types of spray plaster machines: air compressor machines and electric machines.

• Spray plaster machines with air compressors

  Air compressor machines use compressed air and pressure to spray plaster. This is done by mixing plaster in a hopper that is then connected to a spray gun via a hose. Once the air compressor is turned on, the plaster mix is pushed out of the gun by the air pressure which then coats a surface. Air compressor spray plaster machines are available in different sizes, weights, and specs. Choose a lighter model if buyers plan on doing more mobility work while a larger model is suitable for bigger jobs. Generally, air compressor machines have some benefits like lightweight, ease of use, and efficiency. It is also important to note that air compressor machines spray a finer plaster coat compared to other machines.

• Electric spray plaster machines

  This machine uses electricity to spray the plaster. It comes with a mixing hopper and pump system that pushes the plaster mix out of a spray nozzle. Electric spray plaster machines are usually quieter than air compressors. They are also easy to set up and clean. In terms of power, electric spray plaster machines are weaker than air compressors, meaning it can handle smaller jobs only. Some electric machines can handle both spray and backfill functions. This is done by just changing the nozzle. The electric spray plaster machine is versatile, saving the customer money by doing many jobs with it.

Specifications and Maintenance of Spray Plaster Machines

Different machines have specialized features for other purposes. Some of the unique specifications of spray plaster machines include the machine model, spraying capacity, voltage, weight, and the type of material it can handle.

• Machine Model: Machines are available in different models and types, each suited for alternative purposes. The models vary depending on the manufacturer and may have features that change how they look and work.
• Spraying Capacity: Each spray plaster machine has its own plaster spray capacity, which is the amount of plaster or mortar the machine can apply per unit of time. This capacity is typically measured in liters or pounds per minute.
• Voltage: The machine operates at a certain voltage, usually 220-240V 50Hz or 380V/440V 60Hz. This is the power supply needed to run the motor and other electrical parts.
• Weight: The spray plaster machine weighs a specific amount, usually around 100kg (220lbs). Its weight can affect how easy it is to move and lift during construction work.
• Material Compatibility: Machines can spray different materials like lime, gypsum, and cement-based plaster. They are built so that the material can be conveniently loaded, mixed, and sprayed.

The proper maintenance of spray plaster machines helps enhance their lifespan and performance. Some maintenance tips include regularly cleaning the machine to avoid material hardening, lubricating moving parts to prevent wear and tear, and checking for loose parts and malfunctioning components. Compressing air through the machine helps remove plaster residue from hard-to-reach areas. Before starting the machine, the feeding pipe must be inspected to avoid clogging from dried plaster.

Scenarios of using spray plaster machines

Even though plaster spray machines have a wide range of applications, spray machine plastering walls stands out among them. This is because it enhances the quality of plastering interventions-not only for structural integrity but also aesthetically.

In this context, the use of spray machines for plaster represents an effective solution to cover large wall surfaces in a consistent manner without requiring constant manual intervention. In addition, the fast-paced nature of construction sites makes it critical to adopt strategies aimed at reducing time spent on each square meter.

Buying spray plaster machines is a shrewd move for contractors since they can use them in:

• New constructions: Spray machines are widely used in new constructions to apply plaster to walls and ceilings quickly and efficiently. They are ideal for projects where large surface areas require plastering within a short timeframe.
• Renovations and extensions: In renovation projects where existing walls need to be covered or in extension areas added to an existing building, spray machines help achieve a uniform finish for improved aesthetics and increased property value.
• Commercial properties: For commercial properties, such as shops, offices, and warehouses, spray machines can be involved in creating attractive interiors. They can also be used to create fire-resistant or soundproof coatings on walls and ceilings.
• Industrial facilities: Spray machines are practical for constructing industrial facilities, where time is of the essence, and large-scale plastering is required. Using spray machines improves productivity.
• Public buildings: In public building projects, such as hospitals, schools, and government buildings, spray machines help meet construction deadlines while maintaining high-quality standards for plastered surfaces.
• Infrastructure projects: Spray machines also find application in infrastructure projects, such as constructing tunnels, bridges, and retaining walls, where specialized plastering is required for protection or stabilization purposes.

Besides plastering, spray plaster machines can also apply materials like joint compounds, fireproofing, and insulation. Hence, they are handy for other sprayable materials industries, such as the insulation industry, where spray machines must apply thermal or acoustic insulation. They are also essential in the fire protection industry, where spray machines apply fireproofing coatings to structural elements to improve their fire resistance.

How to Choose a Spray Plaster Machine

Consider the following factors when choosing a spray machine for wet plastering.

• Construction Needs and Purpose

  Determine the construction purpose and type of project. Is it for large construction, commercial, small projects, or renovations? Consider the project type. Is it new building construction or a fireproofing and waterproofing project? The project's scale and type will influence the choice of plaster spray machine.

• Material Compatibility

  Choose a spray machine that works with the type of plaster (dry mix, damp mix, or gypsum) that will be used. For instance, a spray machine must effectively handle cement and water-soluble plastic plaster must be used if water-soluble plastic plaster is to be used.

• Ease of Use and Portability

  Factors like weight, size, and whether it has wheels or handles determine the machine's portability. Features such as digital control, remote monitoring, tool-free assembly, and automatic cleaning determine ease of use.

• Machine Capacity and Efficiency

  A capacity of 3-5 liters indicates the machine spray's plastering volume per stroke. A spray rate of 50 liters/hour shows the machine's amount of plaster sprayed in one hour. Choose the capacity and spray rate based on the project size and efficiency needed to meet deadlines.

• Mixer Type

  Choose between a continuous and batch mixer for spray plaster machines according to mixing needs. The choice affects material preparation speed and efficiency.

• Machine's Power

  The machine's spray capacity is affected by its rated power, measured in horsepower (HP). Consider the rated power needed for the project to handle plastering demands efficiently.

• Durability and Maintenance

  The durability and maintenance needs of machines are different according to the material they are made of—aluminum, plastic, or steel. Consider the durability and maintenance requirements of the machine to ensure a reliable and long-lasting plastering solution.

• Budget Considerations

  Apart from the machine itself, other spray béton machines' options, such as different plaster materials, may be more cost-effective. Consider the total cost and value of the plastering solution for budget planning.

FAQ
