Nottefix SELF 520

Description

NOTTEFIX SELF 520 is a self levelling, single component, polymer modified, cement based leveling mortar used on concrete floors not in the desired flatness, with a thickness of 5-20 mm.

Usage Areas

EBUSSELF 520 is used in the leveling and removal of defects of rough and uneven concrete surfaces; in the precast concrete surface plane; in the surface plane before the application of flooring materials such as carpet, ceramic, marble, natural stone, parquet, vinyl, PVC.

Characteristics

It levels by itself.
It can be pumped.
No shrinkage or cracking occurs.
Applicable to underfloor heating floors.
It is used indoors and outdoors.
It has fast hardening feature.
It is resistant to frost.
It can be opened to pedestrian traffic within 3-5 hours and to normal traffic within 24 hours.

Application Method

The surface to be applied should be cleaned and free of oil, paint, dust and free substances. Moisture from below the surface should be avoided. The concrete to be applied must be at least 14 days old and have structural strength to lift the load on it. Cracks on the concrete surface should be repaired with mortar and adherence enhancer EBUFIX/LATEX should be used to ensure that this repair mortar adheres very well to the surface. On under-heated surfaces, the heating system must have been activated 10 days in advance and the heating system must be switched off during application. The heating system can be operated after an average of 72 hours after application.

Each 25 kg of material is mixed with an average of 5.0 lt. of water. First, the required amount of water is placed in a clean container. The material is slowly added and mixed with the mixer until a homogeneous mixture is obtained. After resting for about 1 minute, it is mixed again for 3-5 seconds and applied. The resulting mixture should be applied within 10 minutes.

The prepared mixture is spread on the surface and the desired thickness is obtained with a trowel or rubber broom. Seamless application is required to obtain a uniform and smooth surface coating. The air on the surface should be removed with a hedgehog roll. Precautions should be taken against high heat, direct sunlight and wind to prevent excessively fast drying of the newly applied mixture. In conditions the evaporation, vapor permeable materials such a ceramic can be coated on the screed.

For the coating of non-vapor permeable materials such as PVC coating, it should be waited for at least 3 days and should be done after the moisture rate is measured. Coating materials to be applied on EBUSSELF 520 should be brought to the application area 3-5 days in advance and stored and their compliance with ambient conditions should be ensured.

Consumption

1,9 kg/m² for 1 mm thickness

Packaging and Storage

25 kg Kraft Bag In its original packaging, when stored in ventilated, dry and protected environments at +10°C/+30°C, protected from sun, rain and frost, its shelf life is 1 year from the date of manufacture.

Safety Precautions

Gloves, protective clothing, masks/goggles should be used during application and mixing, contact of the material with the skin and eyes should be prevented. In case of contact with eyes, mouth and skin should be prevented. In case of contact with skin, it should be washed with plenty of water, and in case of contact with eyes and swallowing, a doctor should be consulted.
