Transportation. All modes of transport are allowed.

Warranty storage period. 24 months from the date of manufacture, provided the integrity of the original packaging is not compromised. 0 to +50°C in a dry place

                                                     keep at room temperature.


Perform the work at a surface temperature of the structure between +5 and +35 °C.

Security measures.

During work, it is necessary to use personal protective equipment: rubber gloves resistant to chemicals, cotton gloves, respirator, goggles, overalls made of dense fabric, rubber boots. If resin comes into contact with skin or eyes, rinse immediately with water and seek medical attention.

Surface cleaning.

Using a pump or high-pressure water jet, wash the seam gap, cracks with water.

Preparation of the pump.

Use hand pump "EK-100M" or electric "EK-200". Before using the resin, perform a test flush of the pump with hydraulic oil (eg Mob! HLP-68 or equivalent) in circulation mode.

Installation of injectors.

Usually, metal injectors with ball valves are used. The diameter of the holes should be 1-2 mm larger than the diameter of the injector (for example, if the diameter of the injector is 10 mm, the diameter of the hole should be 11-12 mm).

Cut the capillary rise of moisture: drill holes at an angle in one or two rows at a distance of 10-15 cm from each other so that the holes pass through as many joints as possible between the masonry elements (bricks, stones, etc.).

Crack sealing, concreting of joints: drill injection holes at an angle of ~ 45° to the surface. The distance between holes and recesses from the edge of the crack should be the thickness of concreting joints / structure.

- Clean the holes from drilling debris with compressed air and install the last injector;

- Prevent the leakage of resin on vertical and upper surfaces, for this purpose make a strip of 25x25 mm along the edge of the crack and fill it with "Scrape M500 Repair" solution mixture.

Preparation. It is important!

The temperature of the resin should be at least +17 ° C. As the temperature decreases, the viscosity increases, and as the temperature increases, the viscosity decreases. Before preparing a working volume of resin, prepare a control batch to evaluate the viability of the resin under facility conditions. Prepare the amount of resin that can be used during the life of the boiler:

- Mix the components in the ratio A:B = 1:1 by volume;

- Mix at low speed (up to 300 rpm) for at least 2 minutes.

Execution of injection works. It is important!

Injection of resin into vertical cracks is carried out by sequential injection from bottom to top.

- The injection is carried out until the pressure rises or until the resin begins to flow from the next hole;

- Install the next injector and continue the injection process;

- When the viscosity of the resin increases, wash the pump with a solvent (for example, solvent 646 GOST 18188) and prepare a new part of the resin;

- After the main injection, before the start of its polymerization, carry out an additional injection into the injectors already filled with resin;

- If the injectors need to be removed, fill the hole cavity with Penekrit solution mixture.

Cleaning the pump.

Flush the pump and hoses first with solvent (e.g. xylene or solvent 646 GOST 18188) and then with hydraulic oil (e.g. Mobil HLP-68 or equivalent). Remove the dried resin mechanically.
