A polyurea machine deployed in Dubai enabled a local contractor to complete swimming pool bottom coating with fast curing, strong adhesion, and long-term waterproof performance under high-temperature conditions.
In May 2025, a Dubai-based swimming pool construction company confirmed stable results after using the equipment on commercial and private pool projects exposed to intense heat and continuous water pressure.
Swimming pools in the Middle East require coating systems that cure quickly, resist water penetration, and remain stable under temperature fluctuations. Polyurea-based systems are increasingly selected for pool bottoms due to their seamless waterproof layer and high elasticity.

Project Background: Swimming Pool Construction in Dubai
Dubai has a growing demand for residential villas, hotels, and resort pools. Typical construction challenges include:
- High ambient temperatures exceeding 40°C
- Continuous water immersion after commissioning
- Concrete cracking caused by thermal expansion
- Tight project schedules requiring fast turnaround
The contractor needed a polyurea machine capable of producing a uniform, pinhole-free coating layer on curved and flat pool bottoms without extended curing time.

Problems Faced Before Equipment Upgrade
Before adopting the new system, the contractor relied on traditional waterproofing methods.
Common issues included:
- Long curing time delaying tile installation
- Poor adhesion between waterproof layer and concrete
- Risk of leakage at corners and drainage zones
- Inconsistent thickness caused by manual application
These problems increased maintenance risks and reduced overall pool service life.
Technical Requirements for Pool Bottom Spraying
To address these issues, the contractor defined clear equipment requirements:
- Stable 1:1 material ratio to ensure coating integrity
- High-pressure output for dense, seamless layers
- Adjustable temperature control for material viscosity
- Ability to spray evenly on curved pool surfaces
- Continuous operation without pressure fluctuation
After evaluation, a hydraulic-driven polyurea coating machine was selected for this application.

Application Process on Pool Bottom Surfaces
After surface preparation and moisture control, spraying was carried out directly on reinforced concrete pool bottoms.
Observed performance characteristics:
- Smooth and continuous coating without seams
- Rapid gel time, allowing foot traffic within minutes
- Strong adhesion at corners, drains, and joints
- Uniform thickness across flat and curved areas
The contractor later noted that the same system could also be adapted as a polyurea spray machine for pool walls and auxiliary waterproofing zones.
Performance Results After Project Completion
Based on on-site records and post-curing inspection:
- Waterproof layer thickness deviation remained within ±5%
- Construction time reduced by approximately 30%
- No visible cracks or delamination after water testing
- Material waste reduced due to precise ratio control
The coated pool bottoms passed pressure and leakage testing before tile installation.

Why This Polyurea Machine Was Selected?
The decision was driven by application suitability rather than brand preference.
Key considerations included:
- Hydraulic stability under high-temperature conditions
- Proven performance in continuous waterproofing tasks
- Flexibility for future insulation or coating projects
- Compatibility with other systems, including a polyurethane foam machine for sale used for adjacent insulation work
This reduced the need for multiple specialized machines on site.
Delivery, Setup, and Technical Support
The equipment was delivered after factory testing and configuration confirmation.
Support provided included:
- Pre-shipment pressure and ratio verification
- Operating guidance for pool-specific spraying
- Remote technical assistance during initial projects
- Spare parts support for Middle East applications
Commissioning was completed smoothly without production delays.
