The Power of Surface-Preparation Work

The Power of Surface Preparation Work

Surface preparation doesn’t start with a broom, air blower or power washer. Surface-prep work starts with a drum or rotary-style wet or dry impact device.
 
Impact equipment of scarifiers, grinders, blasters planers, erasers, or shavers are tools used to alter the surface condition, whereas a broom, air, or power washer simply cleans the surface of accumulated dust, dirt and debris.
 
Changing the surface condition to an acceptable state for whatever is planned “next” is the objective of proper surface-preparation work. Next can be the applied coatings, markings, overlay, or repair materials. Next can also be just improving the conditions of the existing surface conditions, then leaving it alone.
 
The use of an impact tool outfitted with the right tools operating in the “impact zone” will get the surface prepared to the right surface profile (SP) condition without causing the surface to micro-crack or bruise. When the surface is properly prepared at the highest level, a condition we call SMITHing, anything applied to that prepared surface will last longer.
 
 
Surface-preparation work requires specialized equipment, manpower, and time to complete the work properly. Allowing coatings, overlay, or repair materials to be applied to a surface that is too porous or too smooth results in premature bond failures and unsafe surfaces.

Always remember that an impact device will NOT be used on the job, if
(1) the job doesn’t clearly specify its use, or 
(2) it’s not a final surface condition requirement.
 
When the surface-prep work is clearly specified, it details what the final surface profile conditions will look like and follow a process like this 4-step.  After the profiling work ends, the final step before application is surface cleaning with a brush, blower, or power washer. 
 
To assure surface-prep work starts with profiling and ends with clean-up, all parties should agree:
  • The work will be clearly defined in contracts
  • The work will be given a pay consideration
  • The work requires agreement as to what the final SP surface conditions will look like

 

Proper preparation work can be a rewarding experience for the applicator, the client, and anyone who walks, bikes, rides or uses the surface. When we shine a light on the value of specifying, performing, inspecting, and paying for proper surface-prep work, everyone benefits.
 
That’s the power of surface preparation work.
 
 

SFO Airfield Marking Removal Symposium Invite

SFO Airfield Marking Symposium Invite

We want to help you remove pavement markings without surface damage or water.

Join SMITH at the San Francisco Airfield Marking Symposium sponsored by Sightline, August 15-16, 2017 and see how.

SMITH will be removing airfield markings with the same machine used by SFO maintenance operations, the  SMITH X3 Dry Rotary Eraser. You’ll see markings being removed without surface grooving, micro-cracking, or water for same day marking re-application. 

Please let me know you would be interested in learning more or will be attending by clicking here.

Hope to see you on the tarmac!

Best removal,

Steven Smith 

P.S. Here’s a 2 minute video from the FLL Airfield Symposium. Enjoy!


Marking Removal 101, Rotary or Drum, what to use on pavements and floors

Marking Removal – Drum or Rotary?

marking removal

On March 22, 2017, Steven Smith presented “Marking Removal 101” at the ATSSA How-To Conference to help stripers decide which style of pavement-marking remover (drum or rotary) is best.

This presentation will help the user select the right equipment to remove and replace pavement markings cost-effectively without ghost lines or grooves.

Leaving grooves when removing markings makes driving and biking unsafe. Grooving also causes pavement surfaces to rut and fail prematurely.
