Polyurethane Liquid waterproofing Bangladesh

Polyurethane Liquid Membrane Waterproofing:

Polyurethane liquid membrane is a group of liquid waterproofing coating based on polyurethane resins.Use together this system  creates a seamless polyurethane liquid roof membrane across terraces,decks or  flat roofs  reliably protecting building structures over the long term, even under the most demanding of conditions.
polyurethane application requires comparatively less skill and supervision. Application is fast and this type of treatment can be used for post construction applications as well.

• Water Tanks / Ponds.
• Roofs.
• Pedestrian Decks.
• Wet Areas.                                                           
                                      
  

Benefits:

• Water Resistant.
• Seamless Membrane without Joints or Leak Risk Areas.
• Water Vapor Permeable.
• Simple Application.
• Adherence to the entire surface.

Polyurethane Waterproofing Procedure:

1.First cleaned the full surface and free it of any foreign matter.
2.If there is any crack on the surface just cut it on V shape,cleaned it and filled it with 1 part polyurethane based crack filling compound and 2 part white cement(1:2).
3.A two pack  primer polyurethane coat is first applied to the surface and allowed it to dry at least 8 hours.
4.After successive these three coats then brush-applied, each with 2 component polyurethane mixed as per design ratio. Each coat is allowed to dry for at least 12 hours for next coating.
5.The final Polyurethane coat is sprinkled with a layer of 300 micron of sand.
