Universal cementitious self-leveling levelling compound for smoothing and leveling substrates from 0 to 10 mm thick.
| Technical | |
| Purpose | Universal cement self-leveling leveling compound for smoothing and straightening substrates in a thickness from 0 to 10 mm. |
| Surface | The substrate must be sound, load-bearing, dry, crack-free, clean and free of stains that impair adhesion (dirt, grease, oil). Inspect the substrate according to the applicable norms and technical data sheets and note any irregularities.Remove any adhesion-reducing substances or unbonded layers, e.g. release agents, unbonded residues of adhesives and levelling compounds, residues of flooring and coatings. This shall be done by brushing, sanding, milling or by intensive sanding with a parquet sander. Thoroughly vacuum the substrate of all residues and dust. Depending on the type and condition of the subfloor, apply the appropriate UZIN pre-coat. The pre-coat should be well dried. Please also refer to the technical data sheets for all other products used. |

| Processing | Pour 6.25 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 to a thick liquid consistency, do not mix too finely. 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 | Self-leveling cementitious levelling compound suitable for application thicknesses up to 10 mm. It is used to prepare flat, absorbent surfaces for the installation of textile and resilient floor coverings in rooms subject to normal to increased loads. |
| 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 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 7 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 specifically 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 for outdoor or wet surfaces. The product is not suitable for use in combination with chipboard and OSB boards. The product is not suitable as a usable pressure or usable surface, so always finish it with a 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. 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. 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 |
