Boost productivity and get consistent results with these shot blasting best practices.
Shot blasting is one of the most effective ways to clean and profile concrete floors. Whether you’re prepping for epoxy or improving surface texture, the right techniques can make or break the job. To help you get the most out of your shot blaster, here are five tips to follow.
1. Choose the Right Shot Blaster for the Job
To start, it’s important to match the size and power of your machine to the workspace.
- Use compact models (8″ or 10″) for tight areas or edges
- Choose larger walk-behind or ride-on units for big, open surfaces
- Always pair your machine with a properly sized dust collector to maintain safe and efficient operation
2. Maintain a Steady Travel Speed
Next, focus on keeping a consistent pace. Uneven speed can lead to poor results.
- Move at a steady pace to ensure even coverage across the surface
- Avoid stopping mid-pass, which can create ridges or overblasted areas
- Mark your lines ahead of time for clean, overlapping passes
3. Check Your Blast Pattern Regularly
As you work, it’s essential to monitor your blast pattern for consistency.
- Clean and inspect the control cage frequently
- Watch for wear on blades and liners that can affect performance
- Select the right shot size based on the surface profile you need
4. Control Shot Flow Carefully
In addition, controlling your shot flow is key to achieving consistent results.
- Start with a lower feed rate and increase it gradually as needed
- Look out for clogs or buildup in the recovery system
- Keep an eye on amp draw with electric machines to avoid overload
5. Keep Your Machine Clean and Maintained
Finally, regular maintenance keeps your equipment in top condition and prevents downtime.
- Clean the shot hopper and dust bin after each job
- Replace worn parts as soon as they show signs of damage
- Inspect your blast wheel regularly for signs of wear
- Check and tighten bolts and inspect alignment before storing
