Description

Product Introduction

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 foreign brands, 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.

Scope

Application Scope

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.

Features

Prep

Subfloor Preparation

  • Thoroughly clear the surface of any oil stains, dust, loose particles, and old coatings for optimal adhesion.
  • Level uneven surfaces by grinding away loose concrete and debris, followed by vacuuming.
  • Ensure the base remains completely dry and free from any standing water prior to application.
  • Use LG660 absorbent interface treatment agent on absorbent substrates, and LG670 on non-absorbent substrates.
Notes

Important Application Notes

Water-to-Ingredient Ratio: Ensure a precise water to mortar ratio of 26% for optimal performance.

1. Select appropriate primer after cleaning. Proceed with self-leveling once dry (2-6 hours after application).
2. Mix 25kg bag with 6 liters of clean water. Use a notched trowel to spread evenly. Shield from direct sunlight and wind. Mix and apply within 10 minutes.
3. Use a defoaming roller to remove trapped air before setting occurs.

Storage

Transportation & Storage

Store in a dry, ventilated, and cool environment, protecting from sunlight and moisture. Sealed products offer a shelf life of up to 6 months. Avoid collisions and compression during transport.

FAQ
