Advantages

  • Self-propagates in order to create smooth surface.

  • Easy-to-apply, low labour requirement.

  • Adheres perfectly even in very small thicknesses without shrinkage, cracking or degradation.

  • Suitable for floor-heated areas.

Areas of Use

  • Indoor and outdoor spaces

  • Housings

  • For ensuring a smooth surface beneath finish flooring materials such as PVC, parquet, wood, carpet, ceramic, marble etc.

Method of Application

The prepared fluid mortar is poured onto the surface. The self levelling mortar’s thickness is then adjusted with a steel trowel. A spiked roller should be used so that no air bubbles remain inside the mortar, the levelling process becomes easier and to make the final surface touches. Application thickness should not exceed 10 mm on any given layer. The product should be applied in different layers in cases where the thickness is larger than 10 mm.

Packaging
  • 25 kg kraft bag
Storage and Shelf Life

The shelf life of the product is 12 months when it is stored on wooden pallets in a cool, dry and moisture free environment with an ambient temperature between +10°C and +25°C.

Surface Preparation

The surface should be cleaned of all residual materials such as dust, oil, dirt, paint, curing materials, bitumen and other foreign substances.

The damaged parts of the concrete, fractures and static cracks on the surface should be repaired with the appropriate YAPIFINE MEND repair mortar first.

Sharp corner and edge joints should be chamfered.

Application Conditions

Should not be applied to surfaces that were exposed to sunlight for too long or to surfaces that are too hot or frozen. Should not be applied when the ambient temperature is not within the values of +5°C and +30°C.

The application area should be protected from the effects of wind and direct sunlight.

The final consumption amount might vary depending on application conditions and surface characteristics.

Depending on temperature and ambient conditions, it can be stepped on after minimum 24 hours. However, it is recommended to wait for minimum 3 days before any beginning any procedures on the surface.

Mixture Preparation

The 25 kg product is slowly poured into 6-6.5 l of clean water. The mixture is then stirred with a low speed mixer until a homogeneous mixture is obtained. The fresh mortar should be used within 30 minutes.

Consumption

1 mm for thickness of 1.7 kg/m²
