Materials processing with a hydrophobic composition GKZH-11K. The procedure for the waterproofing works.
Volumetric hydrophobization occurs as a result of the water repellent agent insertion in the composition of the mixing water into the total volume of the mixture directly in the manufacture of products from cement, concrete, gypsum, clay.
Consumption is about 0.1 - 0.7% by weight of the cementitious product (for cement - not more than 0.2%).
The effectiveness of the water repellent agent depends on the quantitative and qualitative composition of the building mixture, therefore it is always necessary to conduct preliminary tests to determine the optimal dosage of GKZH-A.
Surface hydrophobization is applicable for brick, concrete, gypsum and other building materials.
During surface treatment, the liquid is diluted with water immediately before use.
Dilution rate: add 1 liter of GKZH-A to about 10 liters of water.
The surface must be thoroughly cleaned of dirt before application.
Water-repellent treatment of constructions should be carried out in warm, dry weather at a temperature of no higher than +30°C in two staps with an interval of not more than five minutes. For applying a hydrophobic agent brush, rollers, spray guns are used. It is possible to dip an object into a container. The drips must be removed quickly. Intermediate drying is not required. Upon completion of the operation, the construction should be left to dry completely.
A full drying time at the temperature of +20°C is not more than 24 hours, at a lower temperature, drying slows down and may take longer.
At this time, moisture and rain are not allowed.
The consumption of the working solution depends on the porosity of the surface of the processed material and is 200 - 300 g/m2.
The service life of the coating is 5 to 10 years.
Textile fiber processing:
Store at temperatures from -5°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 6 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.
Water repellent liquids GKZH are 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.
