How Keycoats and Gypsum Plaster Machines are Changing the Game


When it comes to tile installation and plastering, there are many different products and tools available. Two key products in this space are tile adhesive and plaster, both of which are essential for creating a smooth and even surface for tiling. In this article, we will explore the benefits of using keycoats and gypsum plaster machines for tile adhesive and plastering, respectively.

Keycoats for Tile Adhesive

Keycoats are a type of bonding agent that is used to enhance the adhesion of tile adhesive to a substrate. The purpose of a keycoat is to provide a rough surface that the adhesive can stick to, creating a strong and durable bond. Keycoats are typically made from a mixture of cement, sand, and other materials, and can be applied using a trowel or roller.

Benefits of Keycoats

  1. Improved Adhesion: The primary benefit of using a keycoat is improved adhesion. By providing a rough surface for the tile adhesive to stick to, the bond between the adhesive and the substrate is stronger, which can help prevent tiles from shifting or becoming loose over time.
  2. Even Surface: Keycoats can also help create a more even surface for tile installation. By filling in gaps and smoothing out rough areas, key coats can help ensure that tiles are installed on a level surface.
  3. Cost-Effective: Keycoats are a relatively inexpensive solution for improving tile adhesion. Compared to other methods, such as grinding or sandblasting, applying a keycoat is a cost-effective solution that can help save time and money.

Gypsum Plaster Machines for Plastering

Gypsum plaster machines are a type of plastering machine that is designed to apply gypsum plaster to a surface. These machines use a spray nozzle to apply a consistent layer of plaster, creating a smooth and even finish. Gypsum plaster is made from a mixture of gypsum powder and water and is commonly used in construction to create a smooth and even surface for walls and ceilings.

Benefits of Gypsum Plaster Machines

  1. Speed: One of the primary benefits of using a gypsum plaster machine is speed. The machine can plaster large areas in a short amount of time, making it a highly efficient solution for construction projects.
  2. Consistency: Gypsum plaster machines provide a consistent layer of plaster, creating a smooth and even finish throughout the entire surface. This consistency can help ensure that the final product is of high quality and meets the desired specifications.
  3. Reduced Labor Costs: Using a gypsum plaster machine can help reduce labor costs, as fewer workers are needed for the plastering process. The machine can be operated by one or two workers, reducing the overall labor cost for the project.
  4. Safety: Gypsum plaster machines can also improve safety on the job site. Traditional plastering methods can be hazardous, as workers must work at heights and handle heavy machinery and tools. With a plaster machine, workers can operate the machine from the ground, eliminating the need for workers to work at heights.

Other Types of Plaster Machines

In addition to gypsum plaster machines, there are other types of plaster machines available that can be used for different types of plaster. Cement plaster machines, for example, are designed to apply a consistent layer of cement plaster to a surface. These machines are typically used for creating a smooth and even surface for walls and ceilings.

Factors to Consider When Choosing a Plaster Machine

When choosing a plaster machine, there are several factors to consider. One of the most important factors is the type of plaster that will be used. Different types of plaster require different types of machines, so it is important to choose a machine that is designed for the specific type of plaster being used.

Another important factor to consider is the size of the project. Larger projects may require a larger machine that can handle higher volumes of plaster, while smaller projects may only require a smaller machine.

Cost is also an important consideration when choosing a plaster machine. While gypsum plaster machines and cement plaster machines can be expensive, they can also help save money in the long run by reducing labor costs and improving efficiency.

Finally, ease of use is an important factor to consider. Plaster machines should be easy to operate and maintain, with clear instructions and minimal training required.


In conclusion, keycoats and gypsum plaster machines are two important tools for tile adhesive and plastering, respectively. Keycoats can improve adhesion and create a more even surface for tile installation, while gypsum plaster machines provide speed, consistency, and safety benefits for plastering projects. When choosing a plaster machine, it is important to consider factors such as the type of plaster being used, the size of the project, cost, and ease of use. By choosing the right plaster machine for the job, construction professionals can improve efficiency, save money, and ensure a high-quality finished product.
