Vacuum Tanks Restored by TMI Coatings


TMI Coatings, Inc. (TMI) recently completed restoration and lining of two vacuum tanks for a Styrofoam manufacturer due to existing lining failure. The vacuum tanks were experiencing excessive corrosion as a result of the harsh acids and alkalis present in the companies production process. After discussions with the Styrofoam manufacturer, the specific coating material was chosen by TMI due to its compatibility with coating over some of the existing lining material present. TMI devised a plan to complete this project on time, on budget, and safely.


  • Access was provided into each tank through a 16” diameter manway to enter 5’ diameter by 4’ high chambers.
  • TMI prepared surfaces for steel repairs due to corrosion of the tanks utilizing diamond grinders with vacuum attachments and needle guns.
  • After completion of repairs, TMI further prepared all surfaces to bare steel by sandblasting, creating a surface profile for adhesion.
  • TMI then applied two full coats of our urethane elastomer high performance coating system, which provides good corrosion protection against acids and alkalis and abrasion resistance.


Time was of the essence to complete repairs and coating application due to the owners’ tight schedule. Even with unforeseen additional repairs, TMI was able to complete the project within a satisfactory duration to meet the owner’s shutdown schedule. The owner was pleased to have the tanks back up and running for production and stated the project “went good” and they are “not expecting any problems.”
