Shot blasting is a powerful and efficient method used for surface preparation, where tiny steel balls or shots are propelled at high velocity onto a floor surface. This process effectively removes contaminants, old coatings, and creates a roughened texture, making it ideal for the subsequent application of epoxy coatings or other floor treatments. The result is a clean, profiled surface that ensures optimal adhesion for coatings.
Shot blasting is a preferred method for large commercial or industrial spaces due to its efficiency and effectiveness. It’s particularly useful for areas that have accumulated stubborn contaminants, old paint, or other coatings over the years. The roughened texture created by shot blasting is ideal for ensuring that epoxy coatings or resurfacers bond securely to the surface. This method is also environmentally friendly, as it doesn’t use chemicals and captures the removed material for disposal or recycling.
An old manufacturing plant, with floors stained by years of chemical spills and coated with layers of paint, turned to shot blasting to revitalize its workspace. The process efficiently stripped away the old coatings and contaminants, preparing the floor for a new, durable epoxy coating. In another scenario, an airport hangar, which required a floor that could withstand the weight and movement of aircraft, used shot blasting to prepare its surface before applying a heavy-duty protective coating. Additionally, a large shopping mall undergoing renovation opted for shot blasting to remove old decorative overlays from its floors, ensuring a clean slate for its modern redesign.
Shot blasting is particularly effective for quickly and uniformly preparing large areas. While both methods create a profile suitable for epoxy coatings, shot blasting is more aggressive and can remove thicker coatings and contaminants faster than diamond grinding. The choice between the two often depends on the floor’s current condition and the desired finish.
While shot blasting is designed to be a contained process with built-in dust collection systems, it’s not entirely dust-free. However, modern shot blasting machines are equipped with efficient vacuum systems that capture the majority of dust and debris, minimizing the spread and ensuring a cleaner work environment.
Yes, shot blasting is versatile and can be used on both concrete and steel surfaces. The intensity and size of the shots can be adjusted depending on the material and the desired finish, making it a flexible solution for various surface preparation needs.
Once shot blasting is completed and any residual dust or debris is cleaned up, epoxy or another coating can be applied almost immediately. The freshly blasted surface provides an excellent profile for coatings to adhere, ensuring a long-lasting and durable finish.
