Superiority of Polyurea Waterproofing


For many years, polyurethane materials and epoxy coatings have been widely used for waterproofing in various construction facilities. With the emergence of polyurea, the overall level of waterproofing projects has taken a new leap forward.


Polyurea waterproofing technology organically integrates new materials, new facilities, and new processes. It represents a revolutionary leap from traditional construction techniques and is currently one of the most advanced waterproofing construction technologies internationally.


Advantages of Polyurea Waterproofing

  1. Rapid curing, allowing continuous spraying on both horizontal and vertical surfaces without sagging.
  2. Not sensitive to humidity or temperature, with good thermal stability.
  3. 100% solid content, VOC-free, pollution-free, and environmentally friendly.
  4. Excellent physical properties with strong adhesion to concrete substrates.
  5. Seamless coating, providing superior waterproofing performance.
  6. High elongation rate, resistant to cracking under thermal cycling.
  7. Good weather resistance, no powdering or discoloration.


Applications and Construction of Polyurea Waterproofing

Usage: Polyurea waterproofing materials are mainly used for rooftop waterproofing of high-end building facilities, industrial factories, vapor barriers in cold storage, reservoirs, bridges, tunnels, underground projects, cooling towers in power plants, wastewater treatment ponds, aquariums, swimming pool liners, and other areas.


Roof Waterproofing

The construction process of polyurea coatings consists of substrate preparation, priming, and polyurea topcoat application.


  1. Substrate preparation is key to ensuring construction quality. This can be divided into metal substrate and concrete substrate preparation. For metal substrate, first, sandblast the substrate to Sa2.5 level. For defects like weld seams, use epoxy filler to level it. After the epoxy filler has cured, grind it smooth with an angle grinder. Then, clean the substrate and apply two coats of the corresponding primer either by rolling or brushing. For concrete substrate, treat the precast concrete with shot blasting or remove surface dust and residues using an angle grinder or a high-pressure water jet. Once the substrate is completely dry, use a filler to level the surface. For areas that need filling, grind them smooth with an angle grinder after the filler has cured. Afterward, remove surface contaminants and apply a coat of the corresponding primer.
  2. The maximum interval between the application of the primer coats is 24 hours, and the minimum is 3 hours.
  3. The polyurea topcoat should be applied between 3 to 168 hours after the primer application. If the interval exceeds 168 hours, reapply a coat of primer a day before the polyurea application. Before applying the topcoat, use dry high-pressure air to blow away any surface dust.


Feiyang has been specializing in the production of raw materials for polyaspartic coatings for 30 years and can provide polyaspartic resins, hardeners and coating formulations. Some of our polyaspartic coating formulations: Polyaspartic Coating
