GKZH hydrophobic agents are intended for imparting water-repellent properties to porous materials. Water-repellent impregnation GKZH-11 is ideally suits for the treatment of surfaces of brick, marble, tuff, stone, concrete, asbestos cement, tiles, gypsum products and other materials of a similar type. When carrying out construction and repair work of residential, public and industrial buildings and structures, GKZH-11K and GKZH-11N are used as a hydrophobizing additive to concrete and plaster, as an additive, a plasticizer and an air-entraining additive. In the field of oil and gas production, GKZH-11 is a modifier of clay drilling fluids.

Advantages

The application of hydrophobic agents GKZH-11K; GKZH-11N provides the following advantages:

  • It imparts the material excellent water repellency.
  • Decrease in water absorption up to 25 times.
  • Prevents the appearance of "salt traces".
  • Increases frost resistance, crack resistance and light resistance.
  • Prevents surface contamination.
  • Preserves the appearance of the material, its gas permeability and breathability.
  • Economically, as it is used in the form of an aqueous solution when the product is diluted more than 15 times with water.
  • Increases the overall thermal insulation properties of buildings.
  • Increases the life time of buildings and structures.
  • Increases the strength of the material.
  • Prevents materials from cracking.
  • It protects, preventing the growth of microorganisms, lichens, fungi and mold on the surface of the material.

Materials processing with a hydrophobic composition GKZH-11. The procedure for the waterproofing works. 

1. Surface hydrophobization is the treatment with a water-repellent liquid (impregnation) of porous mineral building materials on their surface using a brush or spraying to impart moisture resistance, concrete destruction protection, in order to increase the service life of buildings and constructions, as the surface treated with a water-repellent liquid practically does not absorb water and is not polluted by precipitation.

The surface hydrophobization of the coatings is effective for 4-5 years.

It is recommended to repeat the treatment with GKZH-11K solutions every 3-5 years.

Water repellent protection processing is subject to masonry, wall panels, cement and concrete screeds (floors), limestone, porous stone, slate, tiles, plaster coatings, paving slabs.

The use of GKZH-11K protects against the appearance of “salt trace” on the surface.

Technology of hydrophobization work with liquids GKZH-11K and GKZH-11N

Surface preparation:

Clean thoroughly from dirt, exfoliated plaster areas and blow off dust (sweep mechanically) with air. If necessary, level the surface (cracks, sinks, bumps) with an appropriate mortar.

Preparation of the working solution:

The solution is prepared in the amount necessary for 1-2 hours of operation, based on 55 ml of liquid GKZH-11K per 1 liter of water or 100 ml of liquid GKZH-11N per 1 liter of water.

If necessary to save the working solutions for a longer time (3-4 days), they should be placed in a well-sealed glass or plastic container.

Application method:
Hydrophobic impregnation GKZH-11 in the a solution form is applied to a dry cleaned surface until it is absorbed, avoiding smudges, leaving no drops. It is not allowed to carry out works on the hydrophobization of walls during the rain, as well as after the rain, before the textured layer dries. If an uneven coating is a result of treatment with a liquid, or applied on a porous surface, the treatment should be repeated, but only immediately after the application of the first layer, that is, on a still wet surface. In case if that immediately after the completion of the work it rained, the water-repellent treatment of the surface should also be repeated.

Works should be carried out at a temperature not lower than +5°С.

A contravention of the specified technology (working solution preparation and application), repeated processing on the dried layer, excess of the applied solution, can lead to the appearance of white stains on the treated surface.

Water-repellent impregnation GKZH-11 is applied to the surface with a brush-mowler, roller or spray.

Material consumption on a flat surface:

Consumption depends on the porosity of the processed material and on average is 350 ml/m2.

2. Volumetric hydrophobization is the imparting of moisture-proof properties to building materials by initiation a hydrophobic additive directly into the cement paste (in concrete) in the production of building materials, plaster, basement, etc.

Additive GKZH-11 in the solution for the bulk waterproofing is initiated during the preparation of plaster, cement, concrete solutions, in the production of asphalt and bitumen mixtures, and performs a range of other functions:

Hydrophobic additives GKZH-11K, GKZH-11N in concrete reduces water absorption and water permeability, eliminates capillary leakage.

GKZH-11 is a water reducing additive in concrete, which reduces water consumption for a solution by 1.5 times.

GKZH-11 is a clogging additive that increases the grade of concrete by impermeability.

GKZH-11 is a plasticizer of II, III, IV groups for concrete.

GKZH-11 is an additive that increases the strength of concrete, plaster and screed.

GKZH-11 is an additive that increases the frost resistance of concrete of normal hardening and asphalt pavements, regardless of their composition and type of binder (antifreeze additives to concrete).

GKZH-11 neutralizes acids contained in solutions.

The water-repellent liquids GKZH-11K, GKZH-11N are initiated into the solution together with the mixing water in an amount of 0.1-0.2% by weight of the binder — cement or lime.

Storage
