Elastomeric Waterproofing Coating


Mitchell’s Hardoflex is an acrylic based clastomeric coating for concrete and metal structures such as roofs and walls. Hardoflex provides a seamless, tough and highly flexible film ensuring complete water protection. Hardoflex is UV resistant therefore it is unaffected by sunrays and other weather elements. This in addition to Hardoflex’s excellent bond strength ensures that the film does not disintegrate or peel off over time.


Hardoflex is used to waterproof roofs and walls in homes, offices, factory buildings, warehouses, processing plants, power plants, cinemas, cold storages, schools, mosques and any other structure where protection from water penetration is required.

Hardoflex is applied as per procedure laid down for a good surface paint. The method of application for most applications is

  1. Clean the surface of all dust, dirt, debris, oil, grease, rust and other contaminants.
  2. Soak the surface with water but remove any standing water prior to the application of Hardoflex.
  3. Apply a primer coat and then two flood coats of Hardoflex. The primer coat is made by adding an equal volume of water to Hardoflex and mixing well to obtain a homogenized product.
  4. Hardoflex should be applied by a painters brush, roller or spray machine.
  5. Each coat of Hardoflex must be applied at right angles to the preceding coat and an even covering of the entire surface must be ensured.
  6. Each coat of Hardoflex must be allowed to dry before the next coat is applied.
