Gypsum-based Self-leveling Mortar
Gypsum-based Self-leveling Mortar is a high-performance leveling material with building gypsum as the primary cementitious component. Designed for professional floor leveling applications, it offers superior performance characteristics for modern construction projects.
Key Features
- Quick-drying formulation for efficient project completion
- Low shrinkage properties with excellent crack resistance
- Lightweight composition reduces structural load
- Versatile application across various substrate types
- Safe, environmentally friendly material
Construction Process
Substrate Preparation: Remove all debris, oil stains, and loose materials. Grind or repair uneven surfaces as needed.
Interface Agent Application: Apply specialized interface agent to seal substrate pores.
Material Mixing: Combine with water at manufacturer-specified ratio until achieving uniform, particle-free slurry.
Pouring Construction: Pour mixture into work area, allowing automatic flow to fill uneven surfaces. Large areas may require sectional pouring.
Deaeration Treatment: Use defoaming roller to remove trapped air from slurry surface.
Applications
Ideal for PVC floor leveling in educational, healthcare, and commercial facilities including schools, hospitals, exhibition halls, and libraries. Also suitable as underlayment for floor coatings, radiant heating system backfill, and projects requiring precise floor leveling with high quality standards.
