Teknoser 300 is a hardener for fresh concrete surfaces, which includes corundum chips, hydraulic binder and special chemical additives. Increases the strength properties of the concrete surface by 2 times.

Scope of application

  • For industrial floors of medium and high intensity of operation.
  • For parking lots of cargo and passenger transport.
  • For rooms where heavy equipment is used.
  • For large logistics centers, stadiums, and other socially significant structures.
  • Production shops, warehouses, factories.
  • Shopping centers with heavy traffic, industrial buildings, gas stations, aircraft hangars.


Features and Benefits

  • Economical material.
  • Eliminates the formation of dust from the coated surfaces.
  • Excellent resistance to mechanical shocks.
  • Excellent resistance to coating wear.
  • Creates a strong, smooth and non-slip frost-resistant surface.
  • Increases the impermeability of concrete, increases the resistance to penetration of oils, lubricants, etc.


Instructions for use

Before applying TEKNOSER 300, the appropriate concrete hardness must be achieved, otherwise cracks may appear in the concrete.

TEKNOSER 300 is applied by the "dry-on-wet" method, which means that the hardeners must be applied to non-hardened concrete(approximately 5-6 hours after pouring) for better adhesion of the materials. Topping crumbles in an even layer at the rate of 2-4 kg / m2 and does not require additional watering, since the mixture will independently absorb the necessary amount of water from the concrete. After the hardener absorbs moisture and darkens, it is necessary to treat the coating with a grout machine, paying special attention to the corners and edges of the surface. Then it is necessary to re-fill with the calculation of 2-4 kg/m2 and re-rub the surface in the same way. Depending on the expected load force on the floor, the consumption of the dry mixture may vary.

Application Notes / Restrictions

  • To get the highest quality coating, you need to calculate the optimal time for application.
  • Avoid use in windy, extremely cold and rainy weather.
  • The application of the surface hardener should not be carried out in very windy or dry conditions.
  • Surface hardeners may change color depending on the type of concrete surface.
  • To ensure uniformity and continuity of color, the process of laying the floor should be as protected from environmental influences as possible.
  • Do not add fly ash to the concrete mix, as it accumulates in the upper layer of the slab, which leads to dust release of the floor covering or peeling of the hardener.
  • Do not add water to the concrete mix to increase its workability. This reduces the strength of the concrete and increases the chemical and physical shrinkage, resulting in uncontrolled scratches and cracks.
  • The product may cause irritation if it comes into contact with the skin. Wear protective gloves and safety glasses. In case of contact with eyes, rinse immediately with plenty of water and seek medical attention.
