Universal cementitious self-leveling levelling compound for smoothing and leveling substrates from 0 to 20 mm thick.
| Technical | |
| Purpose | Universal cement self-leveling leveling compound for smoothing and straightening substrates in a thickness from 0 to 20 mm. |
| Surface | ---The substrate must be solid, load-bearing, dry, uncracked, clean and free of stains that impair adhesion (dirt, grease, oil). Inspect the base according to applicable standards and technical sheets and point out any irregularities. Remove any adhesion-reducing substances or non-adherent layers, e.g. release agents, non-adherent residues of adhesives and leveling compounds, residues of pressures and coatings. Do this by brushing, sanding, milling or intensive sanding with a parquet sander. Thoroughly vacuum all residues and dust from the substrate. Depending on the type and condition of the substrate, use the appropriate primer from the UZIN program. The primer should dry well. Also refer to the data sheets for all other products used. |

| Processing | Pour 6.0 to 6.5 liters of cold, clean water into a clean container. Shake the contents of the bag (25 kg) into the container while stirring vigorously. Mix the mixture until a thick liquid consistency without lumps. Use a mixer with the Uzin attachment to mix the leveling compounds. Let the mass ripen for about 3 minutes, then mix it again. Pour the mass onto the pre-coated base and spread it evenly with a trowel or squeegee. Try to achieve the desired thickness of the mass in one application. To improve flowability, or better application of the mass, use a spiked roller to vent the mass. For multi-layer applications, allow the first layer to dry for 24 hours, then apply the UZIN PE 360 primer. When this has dried, add the next leveling layer. The drying time (under normal conditions and with an application thickness of 3 mm) is approximately 24 hours. Sanding is possible after 12-24 hours with 40-60 grit paper. |
| Effect | UZIN NC 160 is a fine-powder, self-leveling cement leveling compound, suitable for application thicknesses of up to 20 mm. Mixed with water, it forms a high-quality, flat layer with excellent strength properties. It is suitable for indoor use. |
| Usage | The product can be stored for at least 6 months in the original sealed packaging in a dry place. Close the opened packaging tightly after use and use the product as soon as possible. Ideal working conditions are: temperature between 15 and 25°C and relative air humidity below 65%. Low temperatures, high air humidity and thicker layers prolong hardening, drying and the interval until laying the floor covering, while high temperatures and low air humidity shorten them. In summer, keep the product cool and use cold water for mixing. For larger loads, the minimum thickness of the mass application is 1 mm for most substrates, and at least 2 mm for cast asphalt. For thicknesses over 10 mm, up to 30% of UZIN MSP quartz sand, granulation 0.2-0.5 mm, can be mixed into the mass. Suitable for mechanical application. The leveling compound applied must be protected from dust and excessive temperature. The following standards, directives and technical sheets also apply or are particularly recommended: DIN 18365: "Laying floor coverings" and technical sheet TKB "Assessment and preparation of the base for floor coverings and parquet work" The product is not suitable as a usable floor or a usable surface, therefore it always finish with floor covering / top coat. Protect the freshly treated surface from drafts, direct sunlight and heat. Cement screeds tend to crack on soft or sticky substrates. Therefore, we recommend that soft or sticky layers be removed before treatment with leveling compound. Even too long open condition of leveling layers accelerates subsequent cracking. For an application thickness of more than 10 mm, you must use an epoxy primer from the UNIPOX Uniconnect family. Dilatations of the extension must be "mapped" onto the surface. If the thickness of the mass application is over 5 mm, you must use the UZIN foam edging tape. The product is not suitable for outdoor or wet surfaces. Cover the dry screed with the final floor covering as soon as possible. When working, use the entire system of Uzin products, otherwise you install the materials at your own risk Before using Uzin products, consult our technical service and follow the instructions on the technical sheets of all materials used |
