Used as filler and repair mortar:
- Indoors and outdoors,
- Horizontal and vertical applications,
- Repair and leveling applications of concrete and reinforced concrete structural elements requiring high strength,
- Filling the gaps between old and new concrete,
- Filling of rod holes and core cavities,
- In chamfer applications before waterproofing applications.
- The ambient temperature should be between +5°C and +30°C.
- Avoid application in humid, rainy and high temperature weather conditions.
- Do not apply on surfaces that are frozen, melting or in risk of rain or frost within 24 hours.
- Surface bearing and stability should be checked to ensure that the surface is solid and clean.
- The application surface must be clean, smooth and solid. Dust, dirt, paint, oil and free particles must be removed from the surface.
- Rusts on the reinforcement should be removed with a wire brush.
- The application surface should be wetted and kept moist.
- ExperRepair SM 12 is placed in a clean mixing bowl. Then, 4,00-4,50 liters of clean water to be used for the mixture should be added to the bowl slowly and mixed with the help of a mixer (400-600 rpm) until a homogeneous and lump-free mixture is obtained.
- The prepared mixture should be rested for 2-3 minutes before application.
- The mixed material is applied to the surface with a trowel.
- If necessary, the second coat should be applied in the same way.
- The thickness should be maximum 10 mm for surface smoothing applications and maximum 40 mm for chamfer applications.
- The surface should be moisturized for 2-3 days after application.
- Do not apply in weather conditions below +5⁰C and above +30⁰C.
- Avoid application in areas that are frozen, in areas with the risk of freezing within 24 hours, in conditions that may prevent the application or that may damage the surface after application.
- Do not apply on surfaces such as stone, gas concrete, plaster, old painted surfaces.
- Should be stored in its unopened original packaging, in a closed, moisture-free, dry environment, protected from frost. Products should not be overloaded in a way to damage their packaging.
- Shelf life under appropriate storage conditions is 12 months from the date of production.
