Excellent material properties and mechanical properties: Polyurea has high tensile strength, high tear strength and good elasticity. It can withstand the external impact and friction caused by frequent movement of people in the stands, installation and removal of seats, and various activities. It can effectively prevent cracks and damage on the surface of the stands and ensure long-term stable use of the stands. Excellent weather resistance: It can be exposed to the outdoor environment for a long time without being affected by natural factors such as ultraviolet rays, wind, rain, ice and snow, and will not discolor or fade.

Material properties

Excellent mechanical properties : Polyurea has high tensile strength, high tear strength and good elasticity. It can withstand the external impact and friction caused by frequent movement of people in the stands, installation and removal of seats, and various activities. It can effectively prevent cracks and damage on the surface of the stands and ensure long-term stable use of the stands.

Excellent weather resistance : It can be exposed to the outdoor environment for a long time without being affected by natural factors such as ultraviolet rays, wind, rain, ice and snow, and will not appear discoloration, fading, powdering, cracking, etc. It can always maintain good appearance and performance, greatly reducing the frequency of repairs and replacements, and reducing maintenance costs.

Strong chemical resistance : For the various chemicals that bleacher surfaces may come into contact with, eg acid rain It has excellent resistance to chemicals, beverages, oil stains, etc., and can effectively prevent chemical substances from corroding the base layer of the stands and protect the integrity and safety of the stand structure.

Good anti-slip properties : By adjusting the formula and construction process of the polyurea material, a coating with a certain roughness and friction can be formed on the surface of the stand, which can provide good anti-slip effects for spectators and reduce the occurrence of slipping accidents even when it is wet or oily.

Construction technology

Basic treatment : First, thoroughly clean the surface of the bleachers to remove impurities such as oil, dust, loose concrete, etc., and then polish and repair uneven areas to ensure that the surface of the base layer is flat, solid, and dry to ensure good adhesion between the polyurea coating and the base layer.

Primer construction : Apply special primer evenly on the treated base layer. The function of the primer is to seal the pores of the base layer, enhance the bonding force between the polyurea coating and the base layer, and prevent rust and moisture at the same time. Primer construction generally uses roller coating or brushing. After construction, you need to wait for the primer to fully dry and solidify.

Polyurea spray : Use professional high-pressure airless spray equipment to evenly spray the polyurea material on the primer surface according to the design requirements. During the spraying process, the moving speed of the spray gun, spraying distance and spraying angle must be strictly controlled to ensure that the coating thickness is uniform and there is no leakage, sagging, etc. Generally, the coating thickness of polyurea sprayed on stands is Between 1.5-3mm, the specific thickness can be determined according to actual needs.

Topcoat construction : After the polyurea coating is cured, a topcoat can be applied as needed to improve the gloss, stain resistance and decorative properties of the coating. Topcoat is generally used with good weather resistance acrylic acid For materials such as polyurethane, the construction method can be spraying or roller coating according to the actual situation.

Advantages

High construction efficiency : Polyurea material has the characteristics of rapid curing and can be tack-dry within seconds to minutes after spraying. It can complete large-area spraying construction in a short time, greatly shortening the construction period and reducing the impact on the normal use of the stadium.

Environmentally friendly and pollution-free : Polyurea materials do not or rarely produce during the production and construction process volatile organic compounds (VOC), meets environmental protection requirements, is less harmful to construction workers and the surrounding environment, and is a green and environmentally friendly construction material.

Overall seamless : Polyurea spraying can form a continuous and seamless coating, effectively avoiding leakage, cracking and other problems that are prone to occur at the joints of traditional materials, and improving the waterproof performance and overall aesthetics of the stands.

Long service life : Due to the excellent performance and good construction quality of polyurea materials, the service life of the stadium stands after spraying polyurea can be up to 20 years or even longer, greatly saving later repair and replacement costs.

Application cases

Large comprehensive stadium : Such as the Beijing Bird's Nest, Guangzhou Asian Games Main stadiums, etc., the stands of these stadiums all use spray polyurea technology, which not only provides spectators with a comfortable and safe viewing environment, but also maintains good performance and appearance after years of use.

professional football field : Spray polyurea technology is also widely used in the stands of many professional football stadiums at home and abroad, such as Premier League Manchester United's home stadium, Old Trafford, Bundesliga Bayern Munich home court Allianz Arena etc. The polyurea coating of its stands is still strong, durable and beautiful despite being able to withstand a large number of spectators for a long time.

multifunctional gymnasium : Some multi-functional gymnasiums used to host basketball, volleyball, badminton and other sports events as well as theatrical performances, exhibitions and other activities. After the stands are sprayed with polyurea, they can meet the needs of different activities and also facilitate daily cleaning and maintenance.
