Rethinking gypsum & concrete wall & facade finishing
with our patent pending spray method and technology.
One nozzle, two worlds
Albér SprayTech has introduced a new, patent-pending spray gun designed to deliver reliable, high-quality application across both gypsum-based products and concrete slurries. Built around a precisely engineered mixing chamber and an extended outlet, the tool bridges two material categories that traditionally require separate equipment. The system is also capable of handling materials with added fibres, enabling the application of fibre-reinforced mortar, gypsum, cement, and concrete without clogging or loss of spray consistency.
Conventional slurry and plaster spray guns typically use fixed nozzles, forcing material through small openings at high pressure. This often results in irregular spray patterns, material waste, uneven layers, and extra smoothing or cleanup. Albér SprayTech’s updated design avoids these issues by using an air-assisted internal mixing chamber, where
compressed air and liquid material combine immediately before leaving the gun. The elongated outlet then spreads the mixture as a smooth, controlled sheet—suitable for both fine gypsum applications and dense slurry mortars, including materials containing reinforcing or insulating fibres.. The result is a cleaner workflow, fewer passes to achieve full coverage, and a more uniform coating thickness.
The Gun
Albér SprayTech spray gun is designed to deliver precise, consistent application across a wide range of materials. Its air-assisted internal mixing chamber combines compressed air and liquid compound just before release, while the elongated outlet forms a stable, uniform sheet of material.
This patent-pending design reduces waste, minimises overspray and ensures even coverage — making the tool a reliable choice for everything from standard gypsum plasters to high-density mortars, including fibre-reinforced materials, and specialised fire-protection products.
Applications
Clean and controlled slurry spraying: In field trials at a major Danish construction firm, the gun was tested with concrete slurry coatings, operated with a standard compressor at just 4 bar. The even output and low overspray make it ideal for structural fireproofing overlays, repair coatings, decorative concrete finishes and retrofit projects — including applications using fibre-reinforced materials. By enabling low-pressure operation with a wide, even spray, the gun simplifies fine concrete applications that previously required heavy or messy equipment.
Fire safety use
Albér SprayTech’s technology is also being developed for fire protection applications using materials such as fire cement and fire-resistant gypsum.
In addition to the spray application itself, Albér SprayTech is developing a patented system combining a lightweight mechanical support structure with an applied fire-protective layer. This approach enables a more stable build-up compared to directly applied coatings, which may crack or give under stress.
The system is designed to ensure consistent and sufficient layer thickness, supporting fire resistance levels of approximately 1.5–2 hours burn-through time, while remaining practical and easy to apply under real jobsite conditions across different geometries (e.g. ducts, steel structures and pipes).
The spraying method and overall system are patent-pending and currently undergoing further development to optimise application quality, material efficiency and compatibility with high-performance fire-protection solutions.
Benefits
Speed & Efficiency
Finish walls and facades in half the time. Projects stay on schedule, and teams move faster from one phase to the next.
Cleaner Process
Less dust, less debris, and almost zero waste. Crews spend time building, not cleaning up.
Health & Safety
No more heavy lifting of gypsum boards. The spraygun is ergonomic, reducing strain and the risk of workplace injuries.
Durability/Quality
Surfaces are strong and seamless. The spray seals around pipes and outlets, improves fire safety, resists mold and flooding damage.
Sustainability
Traditional methods generate piles of off-cuts and waste. Our method uses only what is needed — no paper, no excess, fully recyclable.
