Large stadiums, with high footfall and complex equipment foundations, often have numerous embedded bolts that are prone to leakage. The application of a polyurea elastomer waterproof surface layer offers excellent waterproofing performance. Additionally, since the color of polyurea elastomer waterproof coatings can be customized, and wear-resistant particles can be added to the base material to create a matte, textured surface, it serves as a new decorative surface material that meets both functional requirements and aesthetic appeal.

The entire decorative layer of the stadium grandstand surface is constructed using polyurea spray coating.

Construction process for polyurea elastomer waterproof coating on sports grandstands: Base treatment—Applying sealing primer—Applying 108 adhesive interface agent—Leveling the base with putty—Applying sealing primer—On-site protective treatment—Pre-spraying preparations—Polyurea spraying construction—Applying aliphatic polyurethane topcoat.

By using sprayed polyurea elastomer waterproof coating for construction, the stadium surface achieves a smooth, clean finish with consistent color, clear and smooth edges, and detailed workmanship, meeting the waterproofing and seepage prevention requirements for grandstands. After hosting multiple large-scale events, the grandstand surface shows no signs of cracking or delamination. It demonstrates excellent resistance to sunlight, high temperatures, and wear. After multiple cleanings, no leakage has occurred, fulfilling the requirements for waterproofing, durability, sturdiness, aesthetics, and slip resistance.

We undertake a series of polyurea product constructions: Polyurea anti-corrosion, polyurea spraying, polyurea waterproofing, polyurea flooring, and pipeline anti-corrosion.
