THIXO 71 PU COAT

THIXO 71 PU COAT

"SINGLE COMPONENT FLEXIBLE WATER BASED POLYURETHANE"

THIXO 71 PU COAT is the single component, modified polyurethane, liquid applied coating that is composed of specially developed polymers, properly selected and graded fillers. It cures by reaction with atmospheric moisture to give a tough elastomeric waterproof membrane. THIXO71 PU COAT is elastomeric in nature and has good resistance to weather and sunlight. THIXO71 PU COAT has excellent flexibility and bonding with concrete, breathing properties, water resistance, crack bridging properties, weathering durability.

Areas of Application

  • Open Terrace, any Open Surfaces
  • Foundations, Basements & lift pits
  • Terrace Gardens
  • Sunk portion of bathrooms, toilets, balconies, etc.
  • Car Decks, Podiums

Features & Benefits

  • Cold curing, cures to a tough, flexible and abrasion resistant coating
  • Highly Resistance to sun light and UV rays
  • Bonds strongly on cement concrete, asbestos, mild steel, cement plaster applied surfaces.
  • Thermal stability – Irreversible chemical cure eliminates melting and flow at high temperature.
  • High elasticity - Cures to give a permanently flexible resilient barrier for water over a wide range of temperatures
  • High chemical resistance – Excellent protection against corrosive soil conditions, resistance against saline water, mild acids and alkalis, high sulphate resistance

Method of Application in Waterproofing

Surface preparation :

  • Surface should be clean, dry and free of any lataince, grease, oil, dirt and other loose materials.
  • Concrete surface should have a light steel-trowel followed by a fine hairbroom or equivalent finish which is dry and free of dust, oil and other contaminants. All protrusions to be removed to level the surface.
  • Algae and fungi must be removed physically. After treatment leave for 2-3 hrs and then wash down thoroughly with clean water and allow drying completely.
  • Clean the remains of paint, rust and other contaminants before coating the metal surface.

As a Waterproofing Coating :

  • THIXO71 PU COAT should be applied by Airless Spray , brush/trowel in two coats maintaining the spreading rate to achieve the desired thickness .
  • In critical applications where film thickness is paramount and desired than the stated one then two coats should be applied with quantities per coat gauged to give the specified final film thickness.
  • On a vertical surface if high film build up is desirable then additional coat may be required.
  • If a water ponding test is to be run, the membrane should be fully cured

Technical Data

Precautions & Limitations:

Surface to be dry for application as the material is cured in presence of moisture. Moisture level shall not be essentially more than 0.7%. Soft settling is likely to be observed in containers and the same shall be stirred thoroughly and carefully to achieve a homogeneous consistency. Avoid application on very hot substrate & during very hot and windy conditions. Film formation may not be uniform and gradual under such circumstances & skinning on top surface may lead to formation of blisters and bubbles due to entrapped vapor from within the material. Recoat Can be applied after touch dry and duration will vary depends upon the weather. THIXO71 PU COAT membrane must be cured for a minimum of 4 hours @ 27℃ before placing protection. Where damage to the membrane is possible (by traffic, backfilling, etc) it should be protected by a cementations screed or protection boards. A dust coat of cement should be used to prevent adhesion of the membrane to the boards. A bond with the topping is not required; a separator sheet
