ARDEX K 80 is a self-leveling, cement-based flooring material that provides rapid drying and industrial-grade high strength. Known for its quick-setting and smart screed properties, it is ideal for smoothing and leveling floors before the installation of final floor coverings such as parquet, PVC, and textiles.
Usage Areas
ARDEX K 80 is used to smooth and level floors before the application of final coverings like parquet, PVC, and textiles. This self-leveling, cement-based flooring material can be applied over rough concrete, concrete floors, cement and calcium sulfate screeds. Additionally, it can be used to correct old floors made of ceramic and natural stone, and it is suitable for use as a final layer in basements, workshops, warehouses, and industrial areas.
ARDEX K 80 is self-leveling and fluid, automatically smoothing and leveling itself while hardening. It is suitable for indoor use and offers properties recognized as quick-setting and smart screed by consumers. The product is known for its rapid drying feature and provides industrial-grade high strength.
Product Content
ARDEX K 80 is a gray powder product reinforced with cement, powder polymer, chemicals, and special fillers. Thanks to its excellent fluid consistency, it spreads and levels itself and can be pumped. The product can be worked for approximately 30 minutes and is walkable after about 2 hours. As the mortar dries and completes its hydration, it quickly becomes ready for covering. This floor leveling product has low internal and surface stresses, making it exceptionally durable.

IMPORTANT NOTE
This Frequently Asked Questions (FAQ) section is prepared for general information purposes and does not constitute a definitive guide. For the most accurate and up-to-date information about self-leveling screed applications, especially ARDEX K 80, please refer to the product technical data sheets. For detailed information about product features, usage conditions, and application methods, we recommend consulting the ARDEX Turkey technical team. Before any application, obtaining expert advice on surface preparation and product selection will increase the success of the application.
What is advanced self-leveling screed? Is ARDEX K 80 an advanced self-leveling screed product?
Screeds known as advanced self-leveling screeds in the market are high-performance flooring materials with features such as fast drying, high strength, and self-leveling. These products optimize performance throughout their usage and facilitate the application process. ARDEX Turkey does not refer to these products as advanced self-leveling screed but as self-leveling flooring material. They can be applied under coverings such as parquet, ceramic, and PVC.
How should the surface be prepared before applying self-leveling screed?
The surface must be clean, dry, and solid. Dust, dirt, oil, and loose particles on the surface should be removed. An epoxy primer can be used for non-absorbent surfaces. In case of any discrepancy, it is recommended to conduct a sample application.
What should be the application thickness of self-leveling screed?
There is no general application thickness for decorative screeds. It will vary depending on the product used and the manufacturer’s instructions. For ARDEX K 80, this thickness can range from 5 to 50 mm.
What is the drying time for self-leveling screed?
The drying time varies depending on ambient temperature and humidity. Depending on the product used, this time can range from a few hours to a few days before it becomes walkable. For ARDEX K 80, this time is only 2 hours.
Under what temperature and humidity conditions should self-leveling screed be applied?
The application should generally be carried out at temperatures between +5°C and +25°C with 50% relative humidity. High temperatures and low humidity can shorten the drying time, while low temperatures and high humidity can extend the process.
What should be considered during the application of self-leveling screed?
The surface should be protected from direct sunlight and wind, the mixture should be prepared in the correct proportions, and appropriate tools should be used. Post-application care of the surface and adherence to the drying time are essential.
