FEATURE PERFECT SHOT
The Preparation Group shines a light on the process, applications, and benefits of shotblasting, emphasising its utility in maintaining and restoring surface properties.
Shotblasting is a versatile, efficient, and cost-effective method for preparing a wide variety of surfaces. It is widely used to clean, texture, and provide a profile for surfaces to ensure adhesion and performance of applied materials. However, the success of shotblasting relies on many factors, including the integrity of the multiple surfaces, proper curing, and the operator’s skill in adjusting machine speed and selecting the appropriate grade of shot for the task.
THE SHOTBLASTING PROCESS
Shotblasting involves releasing steel abrasive (commonly called shot) into a high-speed rotating wheel inside the body of the machine. The Blast wheel propels the shot at high velocity onto the target surface, creating the desired profile. The centrifugal force and the suction from the filtration system collects the dust and debris. The shot is recycled via the hopper for reuse, until it wears away, while dust is securely collected in a sealed filtration unit. The process is efficient and environmentally friendly, producing minimal waste.
The surface being prepared must be dry, hard, and reasonably level for optimal results. Shotblasting machines can only be operated with a filtration unit or vacuum attached to ensure cleanliness and environmental safety, producing an environmentally friendly safe operation.
APPLICATIONS OF SHOTBLASTING Shotblasting is suitable for various surface preparation needs:
Concrete Preparation: Removing laitance, keying existing resins, self-levellers, and coatings for upgrades.
Coating Removal: Eliminating waterproofing systems, contaminants, and thin levelling materials.
Steel Preparation: Preparing steel surfaces to standards such as SA2 and SA2.5/SA3.

Asphalt Retexturing: Enhancing the profile of asphalt to expose aggregate and reveal surface defects.
Stone and Tile Cleaning: Texturing and cleaning to prepare for other materials.
Road and Runway Maintenance: Restoring micro texture and macrotexture to improve skid resistance and extend surface life.
MACHINE SPECIFICATIONS AND FEATURES
Advanced shotblasting machines, such as the PPC400 and PPC558 Shotblaster, made here in Britain, are designed for large areas such as warehouses, factories and distribution centres to roads and runways. These machines offer adjustable working speeds, and high production rates of up to 1000m² in an eight-hour day. Made from high-grade manganese steel, they are durable, efficient, and easy to maintain. The hydrovane filtration technology ensures maximum suction, effective dust containment, and minimal downtime for maintenance.
CONCLUSION
Shotblasting is a clean, efficient, and environmentally friendly surface preparation method suitable for various applications. With the right equipment and expertise, it offers unparalleled benefits in improving surface properties, enhancing safety, and ensuring optimal performance of applied materials. Many material manufacturers include this form of mechanical floor abrasion as part of their warranty process. Its proven effectiveness in restoring many surfaces, including road or runway, steel decks and many other textures, highlights its critical role in substrate profiling and maintenance.
