Duratop 400

A colourless low viscosity liquid for application to concrete floors which binds the surface particles together and seals the surface to form a hard non-dusting protective layer.


Product uses

Hardens and dustproofs concrete floors or cement-based wearing screeds and pavings in factories, garages, industrial units and warehousing.




  • Permanent treatment.
  • New or old floors can be treated.
  • Simple and easy to use.
  • Used straight from the container.
  • Economical.



As porosity and texture of concrete floors and cement pavings vary considerably, it is not possible to quote accurate coverage rates, but the following will provide a guide:

Tamped concrete: Approx. 3.5 – 5m² per litre per coat. Applied in a two coat application.

Smooth concrete: Approx. 5 – 7m² per litre per coat. Applied in a two coat application.

Dense power trowelled: Approx. 9 – 10m² per litre per coat. Applied in a one coat application.
