  • masonry walls;
  • foundation walls;
  • docks and ports.


  • Easy preparation and use;
  • Can be applied using brush;
  • IzoKrist fills cracks and provides waterproofing features by means of durable crystals in its composition;
  • Provides protection of concrete and other surfaces from corrosion;
  • Resistant to water pressure;
  • No water vapour transmission, resistance to freezing and melting;
  • Wear resistant crystals in its composition do not decompose or tear away from the surface;
  • Suitable for reliable application in potable water reservoirs.

Application procedures

Preparation of the surface. The cement based surfaces being in contact with water should be healthy, rigid, clean, dust-free, and should have suitable dimensions. The surface should cleaned with water and should be totally free of any fat, rust, paraffin, and other substances deteriorating adhesive force, then it should be finely perforated to increase the adhesive force. Small metal and wooden particles should be removed from the surface. In case the surface has any cavities, they should be removed with  MATON 100 repair mixture. Thoroughly soak the clean surface with water, and do not use it until it is totally dry.

Preparation of the mixture. First pour the IzoKrist powder into clean mixing container, and gradually add water for 3-5 minutes using 400-600 RPM mixer till the solution is entirely homogeneous. Mix again in approximately 3-5 minutes during 30-second period, bringing the product to conditions ready for application. Prepare the solution in the amount required for application within 20 minutes.

Application. Spread the prepared IzoKrist mixture over the surface using brush preliminary soaked with water. While the water is not completely soaked and no crystals have formed, but the first layer is hard enough, apply the second layer. This process may take 3-5 minutes, depending on the ambient temperature. Anyway, the time between applications of the layers should not exceed 6 hours.

Recommendations. It is necessary to prevent quick drying of the surface after application of the IzoKrist product. Substances has been moisture-retaining features should not be used. The surface should be kept wet within 5-7 days by regular splashing water on it. Water reservoirs should be filled with water after application of IzoKrist product, to prolong the period of crystallization and to increase the effect of the mixture upon the deepest layers of the base surface. IzoKrist applied at +230C temperature achieves the design mechanical strength in 1 day, waterproofing features in 7 days, and final hardening in 14 days. 


First layer consumption:  1.2  kg/m2 powder product

Second layer consumption:  1.0  kg/m2 powder product

Shelf Life and Storage Method

The product can be stored during 12 months packed in original sacks in dry and cold conditions. For the short storage period the sacks can be placed on wooden racks one upon the other in three layers, and in the time of application the lower layer sacks should be used first. In case of long-term storage the product packages should not be laid one upon another.


  • In case the treated surface temperature is below +50C and above +320C, the required temperature should be provided;
  • In case of the product application onto external surfaces they should be protected from direct sun rays, wind, rain and frost during 24 hours;
  • The prepared product should be used within 20 minutes.
