PU Spray Applications
From building insulation to chemical-resistant tank linings, polyurethane and polyurea spray systems power some of the most demanding industrial applications. Below: five primary use cases, the JYYJ machine series we recommend for each, and project case studies from real customers.
By Industry
Each industry vertical has its own pressure, hose-length, and chemistry requirements. Our machine lineup spans all three.
Construction & Insulation
Building envelope, roofing, attic, wall, cold storage. Continuous closed-cell PU foam delivers R-6.5 to R-7 per inch with full air-sealing in a single application.
Industrial Coatings
Tank linings, mining wear protection, truck bed liners, industrial floor coatings, pipe & pipeline linings, chemical-resistant coatings, marine and offshore. Polyurea and high-density PU systems handle aggressive chemistries, abrasion, and thermal cycling.
Water Containment & Lining
Potable water tanks and cisterns, irrigation ponds and canals, geomembrane and aquaculture lining, secondary spill containment, and manhole, sewer & wastewater rehabilitation. Seamless pure-polyurea membranes bridge cracks, resist chemicals and UV, and return assets to service in hours.
Cold Chain & Refrigeration
Cold storage panels, freezer rooms, vaccine logistics. -40°C service temperature with closed-cell stability and food-contact compliance paths.
Agriculture & Livestock
Poultry houses, dairy and cattle barns, swine and equine buildings, and grain silos. Closed-cell SPF cuts heating fuel, stops condensation and ammonia, and seals leaky curtain-sided structures.
All Applications

Spray Foam Insulation
High-performance thermal insulation for walls, roofs, attics, and industrial buildings. Seamless, air-tight, energy-efficient.
Polyurea Waterproofing
Fast-curing 100% solids polyurea coating for roofs, terraces, pools, and containment. Seamless waterproof membrane with extreme elongation and tear strength.
Cold Storage Insulation
High-density closed-cell PU foam for walk-in freezers, cold chain warehouses, and food processing facilities operating at -25°C to -40°C.
Spray Foam Roofing
Seamless spray polyurethane roof systems for commercial flat roofs and metal roof retrofits. Self-flashing, reflective topcoat compatible.
Polyurea Tank Lining
Polyurea tank lining and liner systems for petroleum, chemical, water and cistern tanks — seamless, chemical- and abrasion-resistant corrosion protection.
Polyurea Bed Liner
Seamless spray polyurea truck bed liner for pickup beds, fleet vehicles, trailers and equipment — permanent, anti-slip, abrasion- and corrosion-resistant.
Poultry House Insulation
Closed-cell PU spray foam for broiler, layer, and breeder houses — cuts heating fuel, stops condensation and ammonia, and seals the envelope for bird welfare.
Polyurea Mining & Wear Lining
Fast-set pure polyurea spray lining for chutes, hoppers, truck beds, and slurry lines — a seamless.
Livestock & Barn Spray Foam Insulation
Closed-cell PU spray foam for dairy, beef, swine, and equine barns — cuts heating and cooling fuel, stops condensation and sweating.
Industrial Flooring & Floor Coating
Fast-set polyurea and high-build polyurethane floor coatings for warehouses, factories, parking decks, and food plants — seamless, chemical-resistant.
Pond, Canal & Geomembrane Lining
Spray-applied pure polyurea waterproofing liner for irrigation ponds, reservoirs, canals, aquaculture basins, and landfill containment — a seamless.
Water Tank & Cistern Lining
Seamless potable-grade pure polyurea lining for drinking-water tanks, concrete cisterns, ground reservoirs, agricultural water tanks.
Secondary Containment & Chemical-Resistant Lining
Sprayed pure polyurea lining for containment bunds, dikes, spill basins, fuel-farm berms, chemical process floors, trenches, and sumps — a seamless.
Pipe & Pipeline Coating & Lining
Sprayed pure polyurea for internal lining and external coating of oil and gas pipelines, water mains, mining slurry and tailings lines, and penstocks.
Concrete Lifting & Leveling (Slab Jacking)
High-density polyurethane geotechnical foam injected through small drilled ports to raise, level, and stabilize settled concrete slabs — faster, lighter.
Manhole, Sewer & Wastewater Lining
Sprayed pure polyurea protective lining for sanitary manholes, sewer structures, lift stations, and wastewater treatment tanks — seamless, structural-grade.
Marine & Boat Coating
Fast-set pure polyurea spray coating for boat hulls, ballast tanks, pontoons, fish holds, and offshore structures — a seamless, saltwater-resistant.
