UZIN NC 170 LEVELSTAR
SUBSTRATE PREPARATION: The substrate must be sound, load-bearing, dry, free from cracks and free from materials (dirt, oil, grease) that would impair adhesion. Cement and calcium sulphate screeds must be abraded and vacuumed. Test the substrate in ac cordance with applicable standard or notices and report any deficiencies. Any adhesion-reducing or unstable layers, e.g. release agents, loose adhesives, compounds, covering or paint residues, etc. must be removed, e.g. by brushing, abrading, grinding or shot-blasting. Thoroughly vacuum loose material and dust. Use a suitable primer from the UZIN Product Guide according to the type and condition of the substrate. Allow any primer that is applied to dry completely. The datasheets for other used products have to be ob served.

APPLICATION:
3 mm approx. 15 hours*
1. Put 6.5 litres of cold, clear water into a clean container. Sprinkle in the contents of the bag (25 kg) while mixing vigorously until a smooth and lump-free compound is ob tained. Use a mixing device fitted with a UZIN Mixing Paddle. 2. Pour the compound onto the substrate and spread even ly with a smoothing trowel or a screed rake. The flow and surface can be improved by removing air using a spike roller. If possible, apply to the desired thickness in one coat.

A shelf life of 9 months when stored in dry conditions, in the original packaging. The setting and drying times may become longer if the storage time is prolonged. The properties of the cured material are not affected. Care fully and tightly reseal opened packaging and use the contents as quickly as possible. u Best applied between 15 - 25 °C and relative humidity below 65%. Low temperatures, high humidity, little air circulation, dense substrates and large thickness will de lay the setting and drying time. Whilst high temperatures and low humidity, strong air circulation and absorbent substrates will accelerate setting, drying and readiness for covering. In summer, store in cool conditions and use cold water. u Expansion, movement and perimeter joints in the sub strate must be reflected through to the surface. Fit UZIN Foam Expansion Strips to any adjacent, vertical struc tures to prevent the ingress of the compound into the joints. u Can be pumped with continuous, forced-action mixer- pumps, e.g. from manufacturers such as m-tec, P.F.T. and others. u The substructure of wooden floors must be dry to pre vent damage due to damp through rotting or mould for mation. Adequate ventilation or rear-ventilation must be provided especially when installing impermeable floor ing, e.g. by removing the existing expansion strip or by installing special skirting with vent openings. u
