UZIN NC 150 is a very low-emission, cement-based project smoothing compound for leveling substrates and making them ready for covering. The smoothing compound has good flow properties, is highly suitable for pumping, and can be applied in layer thicknesses of up to 10 mm.
After drying, it forms a smooth, highly absorbent surface. This provides a suitable base for textile and resilient floor coverings, such as carpet, PVC, vinyl, and linoleum, as well as for multilayer parquet.
UZIN NC 150 was developed for normal loads in residential and commercial projects and is intended exclusively for indoor use.
Key properties
- Cement-based and self-leveling
- Suitable for layer thicknesses up to 10 mm
- Good flow properties
- Suitable for manual application and pumping
- Very easy to sand
- Highly absorbent surface
- Working time of approximately 20 to 40 minutes
- Walkable after approximately 2 to 3 hours
- Ready for covering after approximately 24 hours
- Suitable for hydronic underfloor heating
- Very low emissions according to EMICODE EC 1 PLUS
- For indoor use
The stated times apply at approximately 20 °C and a relative humidity of 65%. Temperature, humidity, and layer thickness may affect the drying time.
Suitable substrates
UZIN NC 150 can be used, in combination with the correct preparation and primer, on, among others:
- Cement screeds
- Concrete
- Terrazzo floors
- New mastic asphalt floors up to a maximum layer thickness of 5 mm
- Existing ceramic tile floors
- Natural stone floors
- Existing smoothing layers
- Substrates with well-adhering, water-resistant adhesive residues
- Magnesite and wood magnesite
- Suitable dry construction systems
The smoothing compound is suitable as a substrate for, among others:
- Carpet
- PVC and LVT
- Vinyl and CV floor coverings
- Linoleum
- Other textile and resilient floor coverings
- Multilayer parquet
From a layer thickness of 1 mm, the smoothing compound is suitable for hydronic underfloor heating and loads from swivel castors in accordance with DIN EN 12529.
Substrate preparation
The substrate must be load-bearing, dimensionally stable, permanently dry, clean, and free of cracks. Dust, dirt, grease, loose particles, and other substances that may reduce adhesion must be completely removed.
Weak or poorly bonded layers must be sanded, milled, or removed by another suitable method. Then vacuum the substrate thoroughly and treat it with a suitable primer.
Always consult the current product sheet and UZIN's application instructions before use.
Mixing and application
Pour approximately 5 litres of clean, cold water into a clean mixing tub. Then gradually add the full contents of the 20 kg bag.
Mix the material mechanically with a suitable basket mixer until a smooth, homogeneous, lump-free mixture is obtained. Do not add more water than specified, as a mixture that is too thin can affect the strength and drying.
Pour the levelling compound onto the substrate and spread it evenly with a smoothing trowel or levelling rake. Immediately after spreading, use a spiked roller to create an even surface and remove trapped air.
Preferably apply the required layer thickness in a single operation.
Coverage
Average consumption is approximately 1.5 kg per m² per millimetre of layer thickness.
| Layer thickness | Coverage | Area per 20 kg bag |
|---|---|---|
| 1 mm | approximately 1.5 kg/m² | approximately 13.3 m² |
| 3 mm | approximately 4.5 kg/m² | approximately 4.4 m² |
| 5 mm | approximately 7.5 kg/m² | approximately 2.7 m² |
| 10 mm | approximately 15 kg/m² | approximately 1.3 m² |
Actual consumption depends on the evenness, structure and absorbency of the substrate.
