Interior Silo Lining for Fly Ash Silos


North America’s leading producer and supplier of sustainable cement alternatives contracted TMI Coatings, Inc. (TMI) to complete a lining project on the interior of fly ash silos in Cleburne, TX.  Moisture was seeping through the seams of the bolted silos, which was getting into their product and causing the cement alternative to harden.

TMI coated the interior seams using a quality, tried, and true coating system.  First, TMI applied an epoxy prime coat to ensure corrosion resistance. Next, a highly durable and flexible urethane elastomer coating was applied to create a water and chemical-resistant barrier while providing abrasion and corrosion protection.


  • Disconnected lower flanges and cut holes in the silo roofs to allow TMI access to all surfaces inside the silos to allow for ventilation during the lining process.
  • Completed confined space entry procedures for safe access.
  • Safely rigged the interior of the silos with swing stages and baskets for access to all bolted seams.
  • Prepared an area approximately 3” on either side of all seams in the interiors by abrasive blasting to SSPC SP-10 Near White Metal Blast. This removed corrosion and created an anchor pattern for new coating adhesion.
  • Removed and disposed of spent abrasive after obtaining TCLP test.
  • One full coat of epoxy rust inhibitive metal primer was applied. The primer coat prevents corrosion in the areas on/around the seams.
  • Applied the urethane elastomer coating system to seal all the seams inside the silos. This helps prevent moisture from penetrating the seams.


Upon completing the project, the owner stated, “The project has gone better than I could have ever expected.”  TMI Coatings completed another fly ash silo lining project and resolved the moisture issues that were previously present in these silos.  TMI Coatings.
