Repair compound Teknogrout 350(Текногроут 350)

• Before applying the material, the surface should be cleaned of any types of oil, rust, detergents, dirt and other substances that prevent setting.
• The strength of the concrete must be at least 1 MPa.
• If there are active leaks on the surface, they should be eliminated.
• If there is corrosion on the valve, it should be cleaned. If necessary, treat with passivating compounds.
• If it is necessary to work out the seams, you can use Teknopoliderz 1K sealant.
• The tightness can be checked by wetting the surface with water.
• It is necessary to give the surface the necessary roughness.
• The absorbent surfaces should be pre-moistened.
• To prepare the working solution, pour 3.0 - 4.0 liters of clean water into a clean container. Pour the dry Teknogrout 350 compound (25 kg) into a container with water and use a low-speed mixer (400-500 rpm) to knead the composition for 3 minutes until a homogeneous mass is obtained. Leave the resulting compound for 2 minutes, then re-mix. The compound is ready for use.
• Pour the finished compound on one side for 30-40 minutes, evenly distributing it over the entire area to prevent the formation of voids. The height of the fill layer should be from 10 to 75 mm.
• When applying a layer of more than 75 mm, you can add 30% of the filler with a diameter of 5-12 mm to the compound. The filler must be added to the pre-prepared compound and mixed for 3-5 minutes until a homogeneous compound is obtained.

Notes:

• For outdoor use, in the first 3 hours of solidification of the compound, it is necessary to protect the surface from moisture, sunlight and frost.
• The reaction time of cement-based products depends on the temperature of the soil and the environment. At a high air temperature, the reaction time decreases, at a low temperature, it increases.
• When used at a low temperature, it is necessary to use warm water, at an elevated temperature – cold water.
• Work should be carried out in compliance with safety and hygiene standards, using a mask and glasses.
• Do not use the compound for repair work on patchwork surfaces.
• It is recommended to perform the work at a temperature from + 5 °C to + 25 °C.
• The freshly applied solution must be protected from adverse weather conditions, such as direct sunlight, high temperatures < + 35 °C, precipitation and frost.
• The tools and equipment used must be washed immediately after use.
