All Things Coating Supply · Merrillville, IN
A contractor-owned coating supply store in Lake County. Polymer Nation, Premera, US Abrasives, Xingyi grinders and vacs, and EZ Cove — stocked deep for same-day pickup, with a showroom of 80+ finish samples.
The store
ATC Supply is the coating supply house I always wished existed when I was installing floors.
Every product on the shelf, I’ve used. Every tool on the wall, I’ve tested. The store carries complete epoxy, polyaspartic, metallic, flake, quartz, urethane cement, and concrete polishing systems — plus the grinders, diamond tooling, vacs, and sundries to put them down.
Most orders are same-day pickup. For bigger pours, special colors, or bulk quantities, flag the job about a week ahead and it’ll be staged and ready when your crew arrives.
Weekdays 8:00 AM – 4:00 PM
Evenings & weekends by appointment
