How to Use This Daily Job Log

This Job Log can help you manage your daily surface-prep (removal) activities before, during and after the job. Use your smart phone to record any or all prep variables before, during and after the job with the “save this form’ feature. Use one job log for each surface-prep machine.

In an effort to improve this form, please provide your feedback here:

12 Prep Job Variables

We have identified 12 distinct prep job variables that will effect job performance in achieving all 10 surface profiles when using rotary-style or drum-style surface-prep equipment. Rotary-style prep equipment includes grinders, erasers, and waterblasters. Drum-style prep equipment includes scarifiers, planers, shavers, and shotblasters.

  1. Select the right rotary or drum-style equipment and consumable (cutter) drum assembly for the desired surface profile (SP1-SP10) specified, and consistently perform in the “cutter impact zone” (narrow cutting edge position to the surface).

  2. Inspect chassis, drive, power and consumable drum components for wear, loose or malfunction and replace prior to use with stock OEM parts. Stock extra cutter drums and wear parts on the job to reduce downtime.

  3. Reduce the causes for vibrations by replacing worn drive, cutter components and reducing depth of cut on uneven or hard surfaces.

  4. Ensure cutter drums are in balance, correctly spaced and aligned to prevent uneven wear, binding or breakage.

  5. Prevent hard-drop cutter drum starts with soft-lowering mechanisms and inspect that reactive cutter surface depth and pitch angle control mechanisms are properly set and operational.

  6. Ensure the equipment travel speeds and cutter drum rotational speeds are not excessive for the cutter, equipment or surface. Always decrease or increase the cutting impact force required for desired cutter wear, removal performance and surface finish.

  7. Prepare for any surface or material inconsistencies with the correct cutter styles, cutter drum rotation, depth and pitch settings, forward/reverse travel feed rate, cutter to surface exposure ratio and if required a sweeping side-to-side motion to achieve surface profiles.

  8. Always remove in shallow depths with multiple passes when working on uneven and/or hard surfaces.

  9. Control the lateral shear force loads outside the cutter impact zone that may cause cutters to wear, bind or break prematurely.

  10. Prevent overheating components and coatings from continuous removal operations.

  11. Ensure all removed materials evacuate from inside the cutter housing to prevent material buildup and the cutting in the impact zone.

  12. Perform a test strip to dial in the right surface profile and cut depth. Log results and approval prior to starting job.
