The roof was sprayed in August, 2019. It is located in Guangzhou city, Guangdong province . We sprayed our 100% pure polyurea product Qtech-406 for the project. Our water proofing polyurea coating has achieved very good waterproofing, protection and appearance effects.
The construction process is as followed:
1. Clean the substrate.
2. Fill the crack with polyurea joint filler.
3. Primer application.
4. First we need to block the thing not needing spraying to avoid spraying contamination on its surface. Then we can spray pure polyurea.
Polyurea Applications
Pure polyurea material has excellent waterproof, anti-corrosion and anti-abrasion properties. The polyurea coating has no joint and smooth appearance.
Pure polyurea is widely used in different kinds of projects, especially suitable for:
1. Waterproofing projects: high-speed railway, tunnel, sports buildings, roof, underground, pool, water conservancy project, etc.
2. Anti-corrosion projects: exterior & interior pipe line/storage tank, oil pipeline, etc.
3. Wearing resistant projects: ocean projects, industrial flooring, film and television properties, industrial and civil construction etc.
Polyurea can also be applied over a variety of different substrate (concrete, metals, wood and more) in a wide range of temperature and humidity environments. In addition to fixed workshop locations, coating products can be sprayed any time, any place.
Polyurea Features
1. High reactivity and fast curing speed.
2. Not sensitive to temperature and humidity, even can be cured on the surface of the water and ice.
3. Excellent physical properties, such as high die performance, high tensile strength, high elongation, impact strength and so on.
4. It does not contain any volatile organic compounds (VOC), is environmentally friendly, and is non-toxic, odorless and non-polluting.
5. Excellent chemical resistance and decorative.
6. Good weather resistance and aging resistance.
