Landercoll® HPMC significantly enhances the bonding performance of tile adhesives while preventing unwanted lump formation. The result is a strong, long-lasting grip to wall and floor surfaces, ensuring that tiles stay firmly fixed for years without loosening or falling off.
When applied to walls and ceilings, Landercoll® HPMC ensures exceptional water retention and adhesion. This enables gypsum plasters to set into smooth, flawless layers that resist cracking and clumping, providing a stable and uniform finish that stands the test of time.
For both interior and exterior finishing works, Landercoll® HPMC improves the cohesiveness of skim coat and wall putty mixtures. It increases abrasion resistance, creating even, well-bonded surfaces with a refined and polished appearance.
Within cement-based renders and mortars, Landercoll® HPMC plays a crucial role. It ensures superior water retention, better flexibility, extended open time, smoother handling, enhanced crack resistance, and reliable anti-sagging properties — all of which contribute to improved application and durability.
In masonry construction, Landercoll® HPMC improves mixing workability, lubrication, and laying efficiency. It preserves strong bond strength even under heavy loads or horizontal pressure, helping maintain the integrity and reliability of built structures.
For ETICS/EIFS adhesive and embedding mortar formulas, Landercoll® HPMC delivers consistent viscosity, prevents sagging, and reduces unwanted stickiness. The result is a smooth and effortless application process, enabling clean lines and uniform textures across surfaces.
Landercoll® HPMC demonstrates exceptional versatility and reliability across diverse construction applications, delivering consistent quality and performance benefits that professionals trust.
