Floor Preparation Project-Carpark Surface Roughening

Carpark Floor Surface Preparation by CMG-350 with Vacuum

The project involved preparing the concrete carpark surface using the CMG-350 floor grinder, combined with an industrial vacuum . The main objective was to roughen the smooth carpark floor finish, creating an optimal surface profile to improve adhesion for subsequent coating and resurfacing works.

Scope of Work:

• Deployment and setup of CMG-350 floor grinder with vacuum attachment.

• Mechanical grinding of carpark floor to roughen and expose the surface profile.

• Simultaneous dust extraction with vacuum system to ensure minimal dust emission and maintain a safe, clean environment.

• Quality check on the prepared floor surface to confirm required roughness was achieved.

Methodology & Equipment

To achieve the required surface profile, the following equipment was deployed:

• CMG-350 Floor Grinder – for mechanical grinding and surface roughening of the concrete.

• Industrial Vacuum – connected simultaneously to the grinder to perform dust extraction.

The grinder was equipped with appropriate diamond grinding tools, selected based on floor condition, to effectively break the surface laitance and create a coarse texture.

Execution of Works

• Step 1: Site Setup

  • Delivery and positioning of CMG-350 grinder and vacuum.

  • Safety measures implemented (barriers, signage, PPE).

• Step 2: Surface Grinding

  • Grinder operated in multiple passes to uniformly roughen the concrete carpark surface.

  • Special attention given to high-traffic zones and areas with uneven patches.

• Step 3: Dust Collection

  • The industrial vacuum system was operated simultaneously to ensure effective dust extraction.

  • Airborne dust was minimized, maintaining a clean and safe working environment.

• Step 4: Final Inspection

  • The prepared surface was inspected visually and manually tested for required roughness.

  • Confirmation that the surface was ready for coating application.

Outcome & Deliverables

• Carpark concrete surface successfully roughened to achieve the specified surface profile.

• Smooth finish converted into a uniform coarse texture suitable for epoxy, PU, or cementitious coatings.

• Worksite maintained dust-free and safe during the entire process due to effective vacuum system integration.

• Handover inspection confirmed surface readiness for subsequent trades.
