Fast-curing,
spray-applied protection for concrete,
vehicles and industrial linings
Polyurea
Polyurea is a highly reactive, two-component material that cures within seconds of mixing - which is exactly what makes it valuable for waterproofing and protective coating work, and exactly why accurate metering matters more here than for almost any other material 2KM processes.
Because polyurea reacts so fast, it's always spray-applied rather than statically mixed, and the equipment needs to protect the material's moisture-sensitive chemistry right up to the point of application.

Material Properties
Polyurea is a two-component elastomer, valued for its extremely fast cure and durable, flexible protective finish.
Typical Viscosities
Under 10,000 mPas - a relatively low, spray-suitable viscosity, consistent with the fast, fine-coating application polyurea is used for.
Key Processing Notes
Very reactive - the material needs to be spray applied rather than statically mixed.
Moisture sensitive, so moisture-capturing filters are needed on the machine to protect the chemistry through to application.
2KM Machines for Polyurea Processing
- PGM 100 Spray - 2KM's dedicated polyurea spray system, drawing both components directly from 30 litre hobbocks at flow rates up to 3kg per minute, with recirculation & moisture-capturing filtration built in.
Supplier Compatibility
2KM systems are designed to work with materials from a wide range of manufacturers, giving customers flexibility rather than locking them into a single supplier ecosystem.
Rather than being tied to one brand, customers can confidently use approved polyurea materials from multiple manufacturers across their operation.
Typical Applications
Polyurea's speed and durability suit a specific, well-defined set of protective coating applications.
Industries Using Polyurea
1. Construction & Infrastructure - waterproofing membranes for concrete structures, supported by continued UK infrastructure investment.
2. Transport & Logistics - protective bed linings for trailers and delivery vehicles.
3. Marine & Offshore - protective coatings, a sector 2KM's own Market Assessment identifies as expanding.
4. Model Making - spraying of polyurea and polyurethane for props, set pieces and film/theatre work, per Industry Knowledge.docx's explicit mention.
Polyurea - FAQs
What is 2-component polyurea used for?
Polyurea is used for fast-curing, spray-applied protective coatings - commonly waterproofing concrete structures, coating trailer and delivery vehicle beds, and other industrial protective linings.
What 2KM machines are best suited to spraying polyurea?
The PGM 100 Spray is 2KM's dedicated polyurea spray system, drawing both components directly from 30 litre hobbocks and delivering them through a lower pressure spray gun.
Can the machines condition the material to ensure it is optimally processed?
Yes - the PGM 100 Spray includes moisture-capturing filtration to protect polyurea's moisture-sensitive chemistry right up to the point of application, since even small amounts of atmospheric moisture can affect the cured finish. The machine is also supplied with recirculation to keep the material in prime condition.
What kind of flow rates can I expect?
The PGM 100 Spray delivers flow rates of up to 3kg per minute.
Is this an entry-level polyurea spray system?
Yes, this machine has been designed as a budget friendly & portable alternative to the bigger, truck mounted systems in common use. The 2KM machine is lightweight and portable making it perfect for small, localised jobs.
Which industries rely on polyurea spraying?
Construction and infrastructure for concrete waterproofing, transport and logistics for vehicle bed linings, marine and offshore for protective coatings, and model making for spraying polyurea and polyurethane props and finishes.
Does 2KM offer access to demonstration units to help validate a new material or process?
Yes - 2KM has a full test facility for process evaluation and proof of concept before purchase, plus lease and hire options for longer-term on-site testing before you commit.
