How to Apply Polyurethane Waterproof Coating<\/h2>\n

[\/et_pb_text][et_pb_text _builder_version=”4.27.6″ _module_preset=”4f6cad0c-a169-49ec-84cd-4fdf9873e45e” hover_enabled=”0″ locked=”off” global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n

Polyurethane waterproof coatings form a seamless and flexible waterproofing layer and are widely used for roofs, concrete structures, basements, wet areas and other construction applications. However, application requirements vary between single-component, two-component and water-based polyurethane systems. Substrate condition, primer requirements, coating consumption, film thickness, recoat interval and curing time should always follow the technical data sheet of the selected product.<\/p>\n

For concrete waterproofing projects, proper substrate preparation and product selection are particularly important. You can learn more about substrate considerations, typical applications and system selection in our guide to polyurethane waterproof coating for concrete<\/a>.<\/p>\n

The following steps provide a general application overview. Exact procedures should follow the TDS and project requirements for the selected polyurethane coating system.<\/p>\n

[\/et_pb_text][et_pb_text _builder_version=”4.27.6″ _module_preset=”4f6cad0c-a169-49ec-84cd-4fdf9873e45e” hover_enabled=”0″ locked=”off” global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n

1. Surface Preparation<\/h3>\n

The substrate should be structurally sound, clean and free from dust, oil, loose particles and other contaminants that may affect adhesion. Cracks, holes and uneven areas should be repaired before coating application. Acceptable substrate moisture conditions vary by product, so always check the relevant technical data sheet before application.<\/p>\n

[\/et_pb_text][\/et_pb_column][et_pb_column type=”3_5″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ _module_preset=”4f6cad0c-a169-49ec-84cd-4fdf9873e45e” hover_enabled=”0″ locked=”off” global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n

2. Priming<\/h3>\n

Primer requirements depend on the selected polyurethane coating, substrate type and project conditions. Some systems require a compatible primer to improve adhesion, while certain products may be applied directly to properly prepared substrates.<\/p>\n

3. Detail Treatment<\/h3>\n
\n

Pay particular attention to corners, joints, penetrations, drains and other areas where movement or water concentration may occur.<\/p>\n<\/blockquote>\n

\n

Case Study 1: Rooftop Waterproofing for Commercial Building in Shanghai<\/h5>\n

[\/et_pb_text][et_pb_text _builder_version=”4.27.5″ _module_preset=”4f6cad0c-a169-49ec-84cd-4fdf9873e45e” locked=”off” global_colors_info=”{}”]<\/p>\n

Project Overview:<\/strong> A large commercial complex in Shanghai faced recurring leaks on its flat rooftop due to heavy rainfall, thermal expansion cracks, and urban pollution. The 5,000\u33a1 roof area required a robust solution to handle extreme weather variations.<\/p>\n

Challenge:<\/strong> The existing bitumen membrane was deteriorating rapidly, leading to frequent water ingress, interior damage, and high maintenance costs during monsoon seasons. Temperature fluctuations caused cracking, and solvent odors were restricted in the densely populated area.<\/p>\n

Solution:<\/strong> Applied JY-DPU Double Components Polyurethane Waterproof Coating to create a seamless, flexible membrane. Its high-solids, cold-applied formula ensured no solvent emissions, while superior elasticity accommodated structural movements. Technical support included customized installation guidelines for optimal adhesion on the weathered substrate.<\/p>\n

Results:<\/strong> No leaks reported after two years, with enhanced UV resistance and ponding water tolerance extending the roof’s lifespan by 10+ years. The quick 24-hour curing minimized downtime, saving the client on repair costs and earning praise for eco-friendly performance in a high-traffic urban environment.<\/p>\n

Case Study 2: Basement Sealing for Residential Development in Beijing<\/h5>\n

[\/et_pb_text][et_pb_text _builder_version=”4.27.5″ _module_preset=”4f6cad0c-a169-49ec-84cd-4fdf9873e45e” locked=”off” global_colors_info=”{}”]<\/p>\n

Project Overview:<\/strong> A new residential high-rise in Beijing required reliable waterproofing for underground parking and basements, covering over 10,000\u33a1 prone to groundwater seepage and soil pressure.<\/p>\n

Challenge:<\/strong> High water table, constant moisture, and structural settling risked flooding, mold growth, and corrosion of reinforcements, complicating compliance with green building standards in a humid climate.<\/p>\n

Solution:<\/strong> Utilized JY-951 Waterborne Polyurethane Waterproof Coating for its low-VOC, odorless application. The single-component system was brushed on concrete walls and floors, forming an impermeable barrier with excellent adhesion and root resistance for adjacent green areas. Detailed application guides ensured compatibility with existing materials.<\/p>\n

Results:<\/strong> The basements remained completely dry through multiple rainy seasons and harsh winters, preventing mold and corrosion. The project met environmental certifications, with the developer noting a 30% reduction in labor time due to quick drying and ease of use, plus long-term durability against weathering and chemical exposure.<\/p>\n
