Organosilicon liquids GKZH-11 are an aqueous solution of potassium methylsiliconate (GKZH-11K) or sodium methylsiliconate (GKZH-11N).
GKZh water repellents are designed to impart water-repellent properties to porous materials. Water-repellent impregnation GKZH-11 is ideal for treating surfaces made of brick, marble, tuff, stone, concrete, asbestos cement, tiles, gypsum products and other materials of this 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 water-repellent additive to concrete, plaster, as a plasticizer additive and an air-entraining additive. In the field of oil and gas production, GKZH-11 is a modifier for clay drilling fluids.

Application of water-repellent liquids GKZH-11K; GKZH-11N provides the following advantages:
Surface hydrophobization of coatings with water-repellent impregnation GKZH-11K is effective for 4-5 years.
It is recommended to re-treat with GKZH-11 solutions every 3-5 years.
Brickwork, wall panels, cement-concrete screeds (floors), limestone, cellular stone, slate, tiles, plaster, paving slabs are subject to finishing.
The use of GKZH-11 protects against the appearance of a salt trace (efflorescence) on the surface.
Surface Preparation: Remove loose particles that are not bonded to the substrate, remove dust and other contaminants. It is recommended to clean the surface with high pressure washers, steam cleaner, water jet or mechanically. After wet cleaning, allow the surface to dry. It is recommended to apply on a dry, clean, dust-free surface.
Preparation of working solution:
Prepare in the amount required for 1-2 hours of work, at the rate of 55 ml of water-repellent liquid GKZH-11K per 1 liter of water or 100 ml of water-repellent liquid GKZH-11N per 1 liter of water.
If you need to keep working solutions longer (3-4 days), they should be placed in a well-sealed glass or plastic container.
Application
Hydrophobic impregnation GKZH-11 in the form of a solution is applied to a dry, cleaned surface until absorption stops, avoiding smudges, leaving no drops. It is impossible to carry out work on the hydrophobization of walls during rain, as well as after rain until the textured layer dries. In case of uneven coverage obtained after liquid treatment, or application on a porous surface, the treatment should be repeated, but only immediately after applying the first layer, that is, on a still wet surface. In the event that immediately after the completion of work it rained, the hydrophobization of the surface should also be repeated.
Works should be carried out at a temperature not lower than +5°C.
Violation of the specified technology for the preparation and use of the working solution, repeated processing of the dried layer, excess solution can lead to the appearance of white spots on the treated surface.
Application methods
Water-repellent impregnation GKZH-11 is applied to the surface with a brush, roller or spray.
Material consumption on a flat surface:
The consumption of the working solution GKZH-11 depends on the porosity of the processed material and averages 350 ml per 1 m 2 .
Additive GKZH-11 to the solution for volumetric hydrophobization is introduced in the preparation of plaster, cement, concrete mortars, in the production of asphalt and bituminous mixtures, while performing a number of other functions:
Water-repellent liquid GKZH-11 is introduced into the solution together with water in an amount of 0.1-0.2% by weight of the binder cement or lime.
Store at -30 to +30°C in original containers, away from acids. Protect from direct sunlight. Do not store in containers painted on the inside, including those made from aluminum or other light metals.
Warranty period of storage - 12 months.
Storage longer than the date indicated on the label does not always mean that the product is not suitable for use. But if the shelf life is exceeded, it is necessary to check the properties of the product before use.
Water-repellent liquids are non-toxic, fireproof, but have alkaline properties. It is necessary to work in rubber gloves, goggles, spray on the windward side, in a respirator.
