K20 wood floor special leveling self-leveling cement is a ground leveling material specifically designed for the installation of wood flooring. It is made from special cement, fine aggregates, polymer spray dry powder resin from foreignbrands, and cement additives, all carefully formulated.
To enhance the anti-cracking ability of the self-leveling cement, the formula also specially includes wood fiber, making the product's strength reach above 18-20MPa.
This product has high fluidity and plasticity, making it very suitable for leveling work in home decoration with wooden floors. It not only provides a solid foundation but also ensures the flatness of the ground, providing ideal conditions for the installation of wooden floors.
1. Moisture-proof and mildew-resistant, which can extend the service life of the floor.
2. Non-toxic and environmentally
3. Micro-expansion system, no shrinkage, anti-cracking.
4.High fluidity material, with superior leveling performance.

THICKNESS
K20 can be applied with a thickness of 3mm to 8mm in a single construction.
PS: K20 needs to add 8kg quartz sand when making 20mm-30mm thick layer.
1. Thoroughly remove any oil stains, dust, loose debris, and residual old coatings from the surface.
2. Grind uneven surfaces to eliminate loose concrete and debris, then vacuum to clear away residual materials and dust.
3. Ensure the base remains dry, preventing any puddles from forming.
4. For absorbent substrates, employ LG660 water-based absorbent interface agent; for non-absorbent surfaces, opt for LG670 non-absorbent interface agent to ensure adequate preparation.
Maintain a precise water to mortar ratio of 26% for optimal consistency and performance.
1. Post extensive cleaning of the base layer, select a suitable primer. Once the primer is absorbed and starts drying (approximately 2-6 hours post-application), initiate pre-work for self-leveling.
2. Introduce roughly 6 liters of clean water into a container, slowly adding a 25-kilogram self-leveling compound bag. Mix thoroughly with a mixer until entirely smooth and lump-free. Distribute the mixed material evenly, using a specialized notched trowel to manage thickness. Protect freshly mixed material from direct sunlight and strong winds, completing mixing and application within 10 minutes.
3. Prior to setting of the self-leveling compound, use a defoaming roller to eliminate trapped air bubbles. Note: A pump with a delivery capacity of 20-40 liters per minute is recommended for transporting the self-leveling slurry.
TRANSPORTATION
Store in a dry, well-ventilated, and cool environment, safeguarding from direct sunlight and humidity. When sealed, it enjoys a 6-month shelf life.
During transport, exercise caution to avoid collisions and compression, protecting the packaging from damage.
