What Is Synthetic Cob (Kahrang)?

The Kahrang (nano polymeric cob) is a silicone-based resin and water-based paint that looks quite similar to the natural cob after drying. The nano-silicone material is used in the manufacture of synthetic cob (Kahrang), which improves self-cleaning and increases its sealing and insulating properties. Karahang is a modern, waterproof, and dust-free cob mortar that is a good substitute for the traditional cob and simgel. It is suitable for the home environment, especially home interior decoration, as well as renovating historic buildings and creating a traditional facade similar to the desert regions. The synthetic cob (waterproof cob) can be applied by brush or spray and is much easier than other paints. Kahrang (polymeric cob) is highly durable and can be used on different surfaces, including cement, stucco, Knauf, wood, metal, Styrofoam, glass and ...

Cob in Iranian Architecture

Suitable for the home environment, especially home interior decoration, as well as renovating historic buildings and creating a traditional facade similar to the desert regions

Cob mortar is used in Iranian architecture, especially in desert regions. Iranian architects have used cob with tile, wood, stone, and similar materials to decorate buildings. The pleasant color of the cob gave the Iranian cities extraordinary beauty. It gave people's lives a special light and color. They covered the walls of the inner courtyard with the best kind of red clay and created geometric patterns on the walls with embossed stucco lines. Occasionally they drew stucco lines into the vestibule of the entrance and made medallion designs. The cob makes pleasant the intense sunlight to residents. It minimizes the return of sun rays and heat on cob rooftops and walls. One of the most critical problems of traditional cob is its water re-solubility during rainfall and producing dust when the weather is dry. For more information on Cob Mortar, see Wikipedia.

How to apply synthetic cob (Kahrang)?

First, clean and prepare the surface you want. Then dilute the Kahrang (synthetic cob) with water and apply the mixture to the surface using a brush or spray it by a Kenitex spray gun as well as a paint roller

If more thickness is needed, apply the second layer after drying the first layer to give maximum adhesion between the two layers. If necessary, sprinkle some straw on the surface before drying and then coat it with a "nano-insulating resin" to create a dust-free, greasy surface.

The amount of synthetic cob consumed is approximately one kilogram per three square meters, for smooth surfaces.
