Two Component Polymer Modified Waterproofing Coating

Two component polymer modified waterproofing coating (PWC™ code) is a product used to seal surfaces. There are many options for insulating concrete near water such as pools and water tanks and sealing other cement coatings; But which of these options can last against hydrostatic and mechanical pressures has always been one of the most important parameters for choosing the type of insulation and sealing. For example, in the sealing of water tanks, where the hydraulic system is one of the problematic issues, two-component polymer insulation is one of the appropriate solutions. Two-component polymer insulation can withstand all kinds of mentioned forces and therefore assure the consumer that basic sealing has been done. Two-component polymer insulation can also cover all types of joints up to 5 cm.



  •  The ability to withstand all kinds of hydrostatic and mechanical forces
  •  High adhesion with cement and concrete
  •  Very high flexibility
  •  Resistant to various chlorine and Chlorosulfate ions
  •  heat and cold Resistant cycles (-40 to 90 degrees Celsius)
  •  Resistant to abrasions and mechanical shocks
  •  Suitable for cooling factories and iron smelting industries
  •  Applicable on wet surfaces
  •  Unification of the final color of concrete and insulation coating
  •  Reducing costs in the long and short term


Two-component polymer insulation is used in many cases in the construction industry. Its most important application is in concrete and cement sealing. In general, the most important uses of this product are:

  • Sealing pools and water tanks
  •  Sealing terraces
  •  Sealing of parking lots
  •  Sealing bridges
  •  Retaining wall sealing
  •  Sealing of canals and concrete drains
  •  Sealing the floor of the bathroom and toilets
  •  Sealing the walls and facade of the building
  •  Sealing wet environments such as kitchens or sewage treatment plants

Application Instructions

To use two-component polymer insulation, there is no need to mix it with water, and the existing powder and the desired resin are mixed together. One of the advantages of two-component polymer insulation is its quick and easy composition. The surface on which the two-component polymer insulation is to be applied must be free of any dust or oil particles and any sticky particles. Metal surfaces must also be clean before use, and any rust or oil stains must be removed from them. All surfaces should be as smooth as possible before use. Porous and water-absorbing surfaces must also be completely saturated before use; So that there is no excess water on their surface. The specialists of Afzir retrofitting company recommend for better sealing, the implementation of waterproofing in at least 2 layers as follows.

  • Levels of terraces, toilets: 1.0 kg/m² in each layer.
  • On the surfaces where the water is above 1 meter: 1.5kg/m² in each layer
  • On surfaces where water is at least 1 meter above them: 2.0 kg/m² per layer
  • For protective layer: 2.0kg/m² per layer (protective layer is recommended in places that are heavily exposed to water).
