Hot polyurea system

WATERPROOFING OF SWIMMING POOLS

Polyurea is an innovative material resulting from the chemical reaction between isocyanate and polyol. Polyurea can be applied either as a cold application or hot spray. Hot spray polyurea (as detailed below) is a relatively new technology that is continuously gaining traction. All polyureas result from the mixing of at least two components in the appropriate ratio.

Polyurea is used for waterproofing surfaces with varying requirements. After the spraying process, the final product is an elastic and rigid surface without joints and seams, with high resistance to wear, chemicals, and temporal degradation (long lifespan). Depending on the requirements of each application, the appropriate type of polyurea is available, as our company offers a range of more than 20 different materials.

1. Preparation of the surface to the required degree (cleaning, washing, local repairs, removal of loose parts, etc.).

2. Preparation of the materials by preheating and mixing according to the technical datasheets of each material.

3. Priming the surface with the appropriate bonding agent.

4. Once priming is complete and the required time has passed (if applicable, according to each material), and the components of the pure polyurea are ready for spraying, a check is performed on the spraying equipment and the Personal Protective Equipment (PPE) of the applicator and assistant.

5. The spraying process of the pure polyurea begins using a specialized two-component hot spray machine, IS40-Carlisle, during which continuous monitoring of the necessary parameters (temperature, pressure, material flow, relative humidity, application thickness, etc.) is conducted to ensure proper application.

6. As a final layer, a top coat (two coats) is applied in any color of your choice.

7. Once the application is complete, a quality check is conducted using specialized equipment to identify any imperfections or problematic areas, and these are repaired.

Advantages of waterproofing with polyurea:

Polyurea has an incredibly fast application speed, as most materials cure to 80% within 20-30 seconds and can withstand traffic and rain after just a few minutes (15-30). Its reaction, application, and curing are faster than any other technology, resulting in quick completion of work (for example, waterproofing 200m² can be completed in one day).

Polyurea is applied in a single layer to the required thickness and forms a seamless surface without joints and seams, which are the main points of failure in conventional materials.

It can be applied to any surface regardless of shape or difficulty of access, including protrusions or cavities.

It has excellent resistance to impact, abrasion, thermal cycling, standing water, etc. The performance of the material is not affected by moisture and temperature, and when combined with spray-applied polyurethane insulating foam, it can provide a top-tier thermal and moisture insulation system.

With polyurea, the installation of tiles for decoration is not required.

It contains no VOCs or solvents (100% solids) and is an environmentally friendly product."

The primer and preparation depend on the substrate.
