How to recoat a swimming pool with polyurea

Saudi Jomana and AEMCO recently joined forces to recoat a leaking swimming pool, using polyurea and Graco’s Reactor 2 E-XP2.

The owner of a private swimming pool in Al Khobar, Dammam, Saudi Arabia was facing the ultimate disappointment. Some of the tiles had cracked and the water was leaking away. He asked Saudi Jomana to completely renovate the pool. Based in Al Khobar but working throughout the Middle East, Saudi Jomana specializes in the application of seamless polyurea hot spray waterproofing and coating systems. Their experience at solving complex challenges with swimming pools, complemented by their polyurea application knowledge, led the customer to select Saudi Jomana for this job. They in turn joined forces with Graco’s authorized distributor AEMCO. Established in 2007, AEMCO’s focus is on increasing professionalism and productivity in the arena of coating and surface preparation throughout Saudi Arabia.

A 5-day job

The job took five days to complete. The first three days involved site preparation. This involved removing all the tiles, identifying and plugging the leaks, and adding a layer of concrete. The primer was sprayed on day four, and on the final, fifth day, the polyurea and topcoat were sprayed. A team of six men were on site for the duration of the project.

The operators found the E-XP2 comfortable to lift, hold and use. It was easy to operate, smooth to control, and was vibration-free. The operators were also impressed at how quiet it was during operation. The machine was operated from a truck parked outside the compound and hardly made any noise in the neighborhood.

The E-XP2 sprayed both the primer and the topcoat smoothly. No blockages or bounce-back of material was experienced. Time savings were achieved because no premixing or heating were required. The Reactor’s computer control and preset parameters helped to ensure a single seamless coating.

One of the key features of this Graco Reactor is that it measures material consumption. “We found that the E-XP2 used significantly less polyurea than expected,” added Mr. Biju. “We could see from the data that only 2 kg of polyurea were needed to spray a layer 2 mm thick over every square meter of pool area.
