Built for High-Production Sealcoating Contractors
The Seal Rite 850 Extreme Trailer is designed for contractors who demand durability, efficiency, and versatility on every sealcoating project. With its 850-gallon steel tank, reinforced heads and sidewalls, and a rugged trailer frame, this unit allows crews to tackle large commercial lots, industrial properties, and multi-site projects with fewer refills and consistent application. Its extra deck space and organized storage areas keep essential tools and equipment within easy reach, improving workflow and reducing downtime on the job site.
Hydraulic Agitation for Consistent Sealcoat Mixing
A key feature of the SR-850 is its hydraulic agitation system, which uses a 4-inch agitation shaft with infinitely variable forward and reverse speeds. The full sweep, four-paddle system with 3/8-inch rubber wiper blades ensures sealcoat, sand, and additives remain fully suspended, providing a consistent, smooth spray throughout the entire tank. Operators can adjust agitation speed for thicker or sand-heavy materials, keeping spray performance uniform and professional.
Professional Spray System
The trailer includes a 2-inch Wilden air-operated dual diaphragm pump capable of handling heavy sand or additive-loaded sealcoat mixtures. Contractors also benefit from a Hannay 150-foot swivel mount hose reel, 100 feet of 3/4-inch 300 PSI hand hose, and a 6½-foot aluminum spray wand, providing excellent reach and precise control. This professional-grade spray system allows crews to maintain a steady flow rate and smooth application over large surface areas.
