UZIN NC 567 FusionTec is a self-leveling, virtually stress-free thin screed for layer thicknesses of 3 to 50 mm. The product can be used as a bonded screed and as an unbonded screed on a separation layer.
Thanks to its good flow properties and long working time, UZIN NC 567 is suitable for large areas and application with pumping systems. The product forms a level, stable, and absorbent substrate for textile and resilient floor coverings, parquet, ceramic tiles, and natural stone.
The thin screed can also be used for embedding and filling hot-water and electric underfloor heating systems. UZIN NC 567 is also a system component of the UZIN Turbolight System CA.

Applications
UZIN NC 567 FusionTec can be used for:
- Creating a bonded thin screed
- Creating a screed on a separation layer
- Creating virtually stress-free floor surfaces
- Bridging greater differences in height
- Embedding hot-water underfloor heating systems
- Embedding suitable electric underfloor heating systems
- Filling studded-panel and WARP underfloor heating systems
- Large areas processed with a pump
- Use as part of the UZIN Turbolight System CA
Within the UZIN Turbolight System CA, a maximum point load of 2 kN applies. Always refer to the current system documentation.
Suitable substrates
UZIN NC 567 can be used, in combination with the appropriate preparation and system build-up, on, among other substrates:
- Cement screeds
- Calcium sulfate and anhydrite screeds
- Concrete
- Magnesite and wood magnesite
- Screwed-down chipboards of classes P4 through P7
- Screwed-down OSB boards of classes OSB 2 through OSB 4
- Wooden floorboards
- Existing mastic asphalt floors
- Suitable underfloor heating systems
Over chipboard, OSB, wooden floorboards, and mastic asphalt, the maximum layer thickness is 10 mm unless UZIN recommends otherwise for the relevant system build-up.
The floor is suitable for normal loads in residential and commercial areas and for loads from swivel castors in accordance with DIN EN 12529.
Minimum layer thicknesses
- As a bonded layer: minimum 3 mm
- Over a separating layer: minimum 25 mm
- Over a separating layer in combination with UZIN RR 201 renovation fleece: minimum 20 mm
- Over chipboard, OSB, wooden floorboards, and mastic asphalt: maximum 10 mm
For floating or unbonded constructions, the complete floor assembly must be assessed technically in advance.
Substrate preparation
The substrate must be load-bearing, stable, dry, and free of cracks, dust, dirt, oil, and grease.
For bonded applications, all poorly bonded or bond-inhibiting layers must be completely removed by brushing, sanding, milling, or dust-free shot blasting. Then vacuum the substrate thoroughly.
Install suitable UZIN edge insulation strips along walls, columns, pipes, and other vertical building elements. Depending on the type and condition of the substrate, use a suitable primer and allow it to dry completely.
When applying over a separating layer, the load-bearing substrate must be clean and free of loose particles. Install the film or separating layer flat, without folds, and with sufficient overlap.
Mixing and application
Pour 3.2 liters of clean, cold water into a clean mixing tub. Then gradually add the entire contents of the 20 kg bag.
Mix the material mechanically with a suitable basket mixer until a homogeneous, lump-free consistency is achieved. Then pour the material onto the substrate and spread it evenly with a smoothing trowel or a squeegee for large areas.
UZIN NC 567 can also be pumped mechanically. If necessary, use a spiked roller to remove trapped air and improve flow.
Preferably apply the required layer thickness in a single operation.
Consumption
Average consumption is approximately 1.8 kg per m² per millimetre of layer thickness.
| Layer thickness | Consumption | Area per 20 kg bag |
|---|---|---|
| 3 mm | approximately 5.4 kg/m² | approximately 3.7 m² |
| 5 mm | approximately 9 kg/m² | approximately 2.2 m² |
| 10 mm | approximately 18 kg/m² | approximately 1.1 m² |
| 25 mm | approximately 45 kg/m² | approximately 0.44 m² |
| 50 mm | approximately 90 kg/m² | approximately 0.22 m² |
Actual consumption depends on the layer thickness, the evenness of the substrate and the selected system build-up.
Drying time
| Application | Indicative drying time |
|---|---|
| Walkable | after approximately 8 hours |
| Textile and resilient floor coverings at 3 mm | approximately 24 hours |
| Every additional 10 mm of layer thickness | allow for a considerably longer drying time, up to approximately 5 extra days |
For thicker layers, always check that the screed is sufficiently dry before installing moisture-sensitive floor coverings or parquet.

Why choose UZIN NC 567 FusionTec?
UZIN NC 567 is suitable for flooring projects requiring greater layer thicknesses, high load-bearing capacity or the embedding of underfloor heating. Its virtually tension-free curing makes the product suitable for both bonded and unbonded floor constructions.
Thanks to its pumpability, the thin screed can be efficiently applied over large surfaces. The product forms a stable and absorbent base for a wide range of floor coverings.
