Self-leveling Teknogrout EX(Текногроут ЕХ)

1. The surface must be clean, smooth, and firm. Make sure that there are no third-party substances on the surface, such as oils, rust, detergents, dust and dirt. If there are cracks or other damages on the surface, they must be previously repaired with Teknorep 300. Use Teknogrout EX 3-4 days after surface repair.
2. To prepare a working solution for one package (25 kg bag), 3.5-4.5 liters of water is required. Fill the prepared container with clean tap water in the minimum recommended amount and add the Teknogrout EX powder. Mixing is carried out at low speeds (400-500 rpm) for 1 minute until a homogeneous compound without lumps is obtained. It is not recommended to add additional water after mixing the compound. 
3. It is necessary to pour the finished compound on one side on a pre-moistened surface, evenly distributing it over the entire area to prevent the formation of voids. The height of the fill layer should be from 10 to 60 mm. If it is necessary to fill a layer larger than 60 mm, it is recommended to add fillers with a diameter of 5-12 mm to the solution, based on 30% of the total amount of the mixture. The filler must be added to the pre-prepared compound and mixed for 3 minutes until a homogeneous compound is obtained.

Notes:

• For outdoor use, in the first 2 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.
• The freshly applied solution must be protected from adverse weather conditions (direct sunlight, high temperatures < +35 °С, precipitation and frost).
• After application, the equipment must be immediately rinsed with water until the mixture solidifies. Otherwise, it can only be cleaned mechanically.

1. How to repair a concrete floor?
For reliable concrete floor repair, it is recommended to use self-leveling, shrinkage-free repair mortars with high adhesion to concrete and reinforcement, as well as resistance to mechanical stress. One such repair mortar is Teknogrout EX. The material can be applied in thicknesses from 10 to 60 mm, allowing for effective leveling of irregularities and filling of potholes.

2. How to level a concrete floor yourself?
If there are cracks, chips, or holes, the best solution is to use the self-leveling repair mortar Teknogrout EX – a single-component compound with high strength. It is easy to apply, sets quickly, and creates a flat, shrink-free surface.

3. What repair mortar should you choose for quick concrete floor repair?
There are many concrete repair mixtures available, but the choice depends on application thickness, compressive strength, thixotropy or flowability, and adhesion to the substrate and reinforcement. Teknogrout EX is a pourable, single-component, shrinkage-free mortar with high adhesion. As a result, you get a perfectly smooth and durable surface ready for pedestrian and mechanical loads in just two hours.

4. What should be the application layer thickness of a pourable repair mortar?
The recommended application thickness for Teknogrout EX is from 10 to 60 mm. If a thicker layer is needed, it should be applied in multiple stages. Applying a layer thinner than 10 mm is not recommended, as it may affect the strength of the coating.

5. How to repair a hole in concrete?
To properly repair a pothole or deep crack in a concrete floor, use Teknogrout EX. Its shrinkage-free formula and waterproof properties make it suitable even for rooms with high humidity or aggressive environments.

6. How soon can you walk on the repaired surface?
Just two hours after application, the Teknogrout EX-repaired concrete floor can be used, significantly saving repair time and allowing for a quick return to operations.

7. Does the repair mortar shrink after drying?
No, Teknogrout EX is a shrinkage-free mixture that does not deform or crack after curing and requires no additional maintenance. This is especially important when repairing industrial or commercial floors.

8. Why shouldn't you use regular cement mortar to repair concrete?
Cement mortars have low adhesion and shrink, which leads to cracking. For quality repair, it’s better to choose specialized repair mortars like Teknogrout EX. It’s not only strong and durable but also has enhanced adhesion to concrete, doesn’t shrink, and retains its properties even in aggressive environments.

9. Which repair mortars should you choose for concrete?
When repairing a concrete floor, consider whether it’s for residential or industrial use, what loads the surface needs to withstand, and the size of the cracks to be repaired. Teknogrout EX is suitable for filling cracks from 10 to 60 mm, sets quickly, and withstands heavy industrial loads.

10. How to repair cracks in a concrete screed?
If cracks appear on the surface of a concrete floor and it starts to crumble, a good solution is to use Teknogrout EX. It is a self-leveling, shrinkage-free mortar for quick repair of concrete surfaces with damage between 10 and 60 mm deep.

11. The concrete floor is deteriorating in a garage, warehouse, service station, or production area. How to repair it?
To repair and restore concrete surfaces under heavy loads, use repair mortars with high adhesion to concrete and metal, high compressive strength, and self-leveling capabilities. Teknogrout EX gains strength quickly (within 1–2 hours), doesn’t shrink, resists moisture, is waterproof, has excellent adhesion, and withstands freeze-thaw cycles and exposure to various chemicals.
