Fertilizer Towers Sealing and Corrosion Reduction


Fertilizer towers are subject to some of the most corrosive environments. The towers enable the world to store, blend, mix and dispense essential ingredients allowing farmers to produce more products with less land. TMI Coatings, Inc. (TMI) was contracted to assist a Kansas Cooperative with waterproofing and reducing corrosion on their fertilizer tower roof, as erosion caused dozens of holes. TMI devised a plan to rehab the roof with the owner’s assistance.


  1. Before TMI’s arrival, the owner removed all items from the roof and patched any visible holes with new metal.
  2. To neutralize any existing fertilizer, TMI high-pressure washed with Chlorid.
  3. TMI mechanically abraded 100% of the roof to remove rust, mill scale, and create an anchor profile.
  4. TMI primed the roof with epoxy and coated around all the penetrations with trowel-grade liquid and embedded scrim cloth to seal thoroughly from water infiltration.
  5. Finally, the crew applied two heavy coats of a urethane elastomer coating and added grit for a non-slip finish. The coating bonds tenaciously to irregular surfaces and offers a flexible, high-performance finish.
