As a metal fabrication provider, we understand the importance of maintaining and enhancing the durability and aesthetics of metal surfaces. Sandblasting is an effective process that we highly recommend to achieve these goals. In this blog post, we’ll explore the benefits of sandblasting and what to avoid to ensure its optimal use.
What is sandblasting?
It is a process that involves the use of compressed air and abrasive materials to clean and prepare metal surfaces for further treatment such as painting or coating. The process works by propelling abrasive particles at high velocity to remove rust, paint, and other contaminants from the metal surface, leaving a smooth and clean finish. The abrasive materials used can vary depending on the specific application and can range from sand to glass beads, aluminium oxide, or steel shot. This is a highly effective method for surface preparation, as it can remove even the toughest coatings and contaminants from the metal surface.
What are the benefits of sandblasting?
It restores rusty equipment
Rust is a common problem in metal equipment and structures, especially those exposed to moisture and harsh environmental conditions. This is particularly true for regions such as Queensland, where humidity levels are high during the wet season. Sandblasting can effectively remove rust, extending the lifespan of the equipment. Additionally, it can identify underlying corrosion issues that may require further attention.
It smooths surfaces for painting
A surface profile is created that enhances the adherence of paint and coatings, improving their longevity. Without proper surface preparation, the paint may not stick effectively to the metal, leading to premature failure. Sandblasting eliminates the need for manual sanding and ensures a consistent, uniform surface profile.
It increases paint longevity
In addition to improving paint adherence, it removes contaminants that can contribute to paint degradation. These contaminants, such as grease and oil, can cause premature paint failure. Removing contaminents can significantly increase the lifespan of the paint.
It is cost-effective
Sandblasting is a highly efficient process that saves time and money compared to other methods of surface preparation. When you undertake professional services, there is no need for manual sanding, in-turn reducing the labour time for surface preparation. Additionally, sandblasting can be used on large or complex surfaces that may be difficult to clean using other methods.
What to avoid when sandblasting:
Even though sandblasting seems relatively easy, don’t try to do this yourself. It’s always best to leave it up to the professionals who know the tricks of the trade. There are some key considerations to take into account before starting sandblasting that require expert knowledge. Some of these include:
- Choosing the right abrasive material: The type and size of abrasive material used in sandblasting can impact the final result. Some materials may be too harsh and damage the metal surface, while others may not effectively remove contaminants. Choosing the appropriate abrasive material for the specific application is crucial to achieving optimal results.
- Controlling the air pressure: Air pressure is a critical factor in sandblasting, as too much pressure can damage the metal surface, while too little pressure may not remove contaminants effectively. It is essential to monitor and adjust the air pressure to ensure the best possible outcome.
- Wearing appropriate personal protective equipment (PPE): Sandblasting can produce a significant amount of dust and debris that can pose a health risk to workers. Wearing appropriate PPE, such as respirators and protective clothing, is crucial to prevent inhalation of hazardous materials and skin exposure.
Sandblasting offers numerous benefits such as removing rust from metal fabrications and preparing the material for painting. It is an effective method to restore metal fabrications and achieve a beautiful finish. However, precautions must be taken before proceeding with the process. Following safety guidelines and working with a professional sandblasting company like the Fab Company ensures the benefits of sandblasting while maintaining safety for everyone involved.
