  • High water retention, lightweight with high strength

  • low shrinkage, strong adhesion

  • high impact resistance, excellent durability

  • low consumption per unit area, and wide application range.

Category:
  • Remove dust, dirt, and loose layers from the substrate. Roughen the shear wall interface; no treatment needed for AAC substrates. Reinforce joints of different materials.
  • Mixing: Use a powder-to-water ratio of 1:0.34 – 0.37. Add water first, then mortar, and mix for 3 minutes until smooth and lump-free.
  • Layered Application: Press the first layer firmly against the substrate (thickness ≤10mm). Apply the second layer after 24 hours. Use a straightedge to level once at full thickness. If total thickness exceeds 30mm, reinforce with alkali-resistant fiberglass mesh.
  • Details: Press mortar firmly on both sides of guide strips to avoid voids. Clean skirting areas thoroughly. Finish the surface slowly to prevent hollowing caused by the leveling tool.
  • Curing: Natural curing only; no water spraying required.

This product complies with the technical requirements of GB/T 25181-2019 Ready-mixed Mortar.

NOTE

  • Temperature: 5°C – 35°C; weather affects drying time.
  • Pot Life: Use within 2 hours (at 25°C); do not remix with water once hardened.
  • Joints: Avoid overly thin joints to ensure mortar strength.
  • Storage: Seal opened bags; store in a cool, dry place.
