Shot Blasting Clarity

Concrete Prep Part 3: Is Shot Blasting Necessary for Epoxy Garage Floor Coatings? There’s a lot of confusion around concrete shot blasting, so we decided to clear the air and provide some clarity on this process for your epoxy garage floor coating project in Toronto, Mississauga, Vaughan, the GTA, Scarborough, and Brampton. Shot blasting is a technique that involves propelling abrasive materials at high speeds onto the concrete surface, effectively removing fine particle contaminants such as dirt and dust to prepare the substrate for your residential epoxy flooring.

Adhesion Benefits

It’s often performed after diamond grinding the concrete, and by creating a clean and roughened surface, shot blasting accomplishes a CSP 3 profile that enhances adhesion with concrete coating services. Is shot blasting required for every epoxy flooring Toronto project? The answer to this question is—it depends on the coating. Some coatings require a CSP 3 profile, which is necessary for their mechanical bond between the concrete and the coating, preventing delamination and premature failure of your garage floor coating.

Cost Efficiency

However, a number of our coatings require only a CSP 2 profile, which is obtained through diamond grinding and doesn’t necessitate shot blasting, saving costs for our clients with concrete coating services across the GTA. Ultimately, in some cases, shot blasting ensures that the coating can perform optimally, protecting the concrete substrate from damage and extending its lifespan, while in others it’s completely unnecessary—we assess each job to decide.
