Hind Pentro Hard


Category: .



Hind Pentro Hard is used for case hardening of concrete surface and to obtain  absolute Dust proof surface. On its application  a improved highly chemical resistant surface is obtained. It is used for all type of industrial concrete floors, warehouses, chemical processing plants, car park and basements, storage silos, sewage plants, refineries and heavy pedestrian floor trafficking areas in civic centres, stadium, airport, hospitals and museums.

Floors constructed with metallic floor hardener can be protected to prevent oxidation on its application on the floor surface.


  • It provides a tough abrasion resistant surface which does not turn yellow or decolorizes .
  • Single component, ready to use.
  • It penetrates deep into the surface, densify and hardens concrete which does not allow entry of moisture or any other foreign matter
  • Scratch and peel proof.
  • Chemical resistant and dustproof and surface becomes abrasion resistant .on its application.
  • It is cost effective due to high coverage.


New Concrete Surface: It can be applied over new concrete surface after final trowelling.

Over Old Concrete Surface: Before application over old concrete surface, the surface is to be vigorously cleaned by wire brush, chipping or grinding so that it becomes free from oil, dust, grease, algae and any rust scale. Over the cleaned dry surface Hind Pentro Hard is to be applied by spraying, squeegee or broom after slightly agitating the mixture in the container. The material to be scrubbed with a mechanical scrubber on the surface until it gels ( min. 45 minutes). After such operation spray material with water and continue to work on the surface for few more minutes (7-8 mins) Excess material to be cleaned by squeegee or a mop. Finally the surface is required to be flushed with water. It is recommended to recoat the surface where is surfaces is porous and penetration even takes place after the first coat.  The drying time of Hind Pentro Hard depends on the nature of the concrete surface. If the surface is new and fresh it gets dried up within 2-3 hours. For old concrete drying time may get extended due to surface conditions. Traffic should not be allowed between 4- 12 hours on coated surface.
