ArmorThane applicators spray polyurea and polyurethane linings on concrete and steel storage structures. Silo owners can request a quote or find a local applicator.

Line it, seal it, keep it filling. Practical guidance on inspecting, repairing and spray-lining concrete silos, steel grain bins and storage tanks before corrosion and spalling cost you a season.
Every lining job starts inside the empty structure: mapping spalled staves, exposed hoops, wet seams and old coating failures, then blasting to sound, profiled concrete or bare steel.
Spray-applied polyurea cures in seconds, bridges hairline cracks and resists the abrasion of grain flow and the acids that silage produces. Food-contact suitability depends on the specific system, so confirm it with the applicator.
Condensation, fertilizer dust and wet grain attack galvanizing at the bolt lines and floor ring first. A primer and elastomeric lining system can stop rust from undercutting the shell.
Feed, water and liquid-fertilizer tanks, plus the containment around them, need a lining matched to the stored chemical and to how much the concrete moves.
Clean-out, confined-space safety plan, and a close look at every stave, seam and hoop.
Patch spalls, seal cracks, blast to profile and prime for the chosen system.
Heated plural-component spray, built up to the specified thickness in one visit.
Thickness readings, holiday checks where specified, and a record before the first load.
A quick area check to include with your quote request. It doesn't give a price; pricing depends on prep, thickness and site conditions.
It depends on the specific product. Ask the applicator for the manufacturer's data and any food- or feed-contact approvals for the exact coating before it's used in a storage structure.
Yes. Have structural damage assessed and repaired first. A coating protects the surface but isn't a structural repair.
Typically by cleaning out residue, removing loose or deteriorated concrete, profiling the surface, priming where specified, and blasting steel to bare metal. Prep quality largely decides how well a liner bonds.
Polyurea cures quickly, but total downtime depends on cleaning, repairs, access and weather. Your applicator can give a realistic schedule.
Yes. Confined-space entry, fall hazards and residual gases are serious risks. Use trained contractors who follow confined-space procedures.
