Founded by Gary King and Danny King, DG Hot Rubber Sealant was built on decades of hands-on experience and a deep understanding of the demands placed on grain bins, Quonsets, and industrial roof systems. Based in Effingham, Illinois, the company has spent more than 20 years delivering high-performance hot rubber sealant systems designed to withstand structural movement, extreme temperatures, and harsh agricultural environments.
Specializing in grain bin sealing, Quonset sealing, and roof coatings, DG Hot Rubber Sealant provides durable, flexible solutions that protect steel, concrete, and stored materials from water intrusion, air loss, and corrosion. Our hot-applied rubber systems are engineered to flex with the structure, providing long-term protection where rigid materials fail. With nationwide service, we support farms, grain companies, co-ops, grain elevators, and industrial facilities across the country
