Product description

Water-repellent agent Aquaprok-1 Concentrate


Aquaprok-1 Concentrate is an aqueous solution of potassium methylsiliconate.


Aquaprok-1 Concentrate is designed to impart water-repellent properties to porous materials. Water-repellent impregnation Aquaprok-1 Concentrate is ideal for the treatment of surfaces made of brick, marble, tuff, stone, concrete, foam concrete, asbestos cement, slate, tiles, gypsum products, shell rock, mineral plasters, limestone, and other materials of similar type.

During carrying out construction and repair work in residential, public and industrial buildings and structures, silicone fluids Aquaprok-1 Concentrate is used as a water-repellent additive to concrete, plaster, as an plasticizer additive and air-entraining additive.

Not suitable for wooden surfaces processing. Covering the previously painted and glass subjects can lead to formation of spots. It is exceptionally
suitable for processing vertical and inclined surfaces on which liquid sediment and moisture condensate can be removed.


Surface treatment with water repellent Aquaprok-1 Concentrate will allow:

  • extend the service life of treated surfaces by 3 to 5 times, preventing the appearance of fungi and moss;
  • 2–3 times increase the frost resistance of buildings and 1,5–2 times the corrosion resistance;
  • reduce water absorption by 1.5 times;
  • keep heat by reducing heat transfer through walls and ceilings;
  • avoid repeated salt traces;
  • improve mud protection properties.

Materials processing with a hydrophobic composition Aquaprok-1 Concentrate. The procedure for the waterproofing works. 

1. Surface hydrophobization: 

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

Application: The working solution is prepared at the rate of 1 liter of product for 3 liter of water, in the amount necessary for 1-2 hours of work. It is applied with a brush, roller or spray to a dry, cleaned surface until it stops absorbing, preventing drips and leaving drops. Do not carry out work in the rain, as well as at temperatures below +5°C.

Caution: Repeated processing on a dried layer may cause white salt traces.

Consumption depends on the porosity of the processed material, and is on average 350 ml/m2 (1 liter of Aquaprok-1 Concentrate is sufficient to process an average of 12 m2 of surface).

2. For volumetric treatment: When preparing mortar and concrete, the agent is introduced together with mixing water in the amount of 0.25-0.5% of the weight of the binder - cement or lime.


Store at temperatures from -15°C to +30°C in original containers separately from acids. Protect from direct sunlight.

Do not store in containers painted inside, as well as containers made of aluminum or other light metals.

The guaranteed shelf life is 12 months.

Storage over the date specified on the label does not necessarily mean the product is unusable. In case, if store more please check the properties of
product before use.

  • combined drums (steel - polyethylene) with a capacity of 200 dm3;
  • special containers (IBC) with a capacity of up to 1 m3.

Safety information

Water repellent agent Aquaprok-1 Concentrate is non-toxic, fireproof, but have alkaline properties. Use rubber gloves, goggles, respirator during works. Spraying should be processing from the windward side.

Detailed instructions are given in the appropriate product safety data sheet. It can be provided upon request.
