Self-Leveling Compounds Additives

What Is Self‑Leveling Mortar?

Self‑leveling mortar, or self‑leveling cement, is a high‑performance floor substrate designed to automatically spread under its own weight to create a smooth, even, and durable base.

In modern construction, self‑leveling mortar additives are critical to control viscosity, prevent segregation, and ensure consistent hydration.

LANDU's advanced additive system fine‑tunes every self‑leveling mix — optimizing flow control, water retention, and curing behavior across different temperatures and environments.

Why Additives Make the Difference in Self‑Leveling Mortar

The quality of any self‑leveling floor depends largely on its cement additive system. LANDU's materials scientists engineer each component — from cellulose ether HPMC to PCE superplasticizers — to achieve superior rheology, mixing stability, and final surface finish.

Performance Advantages:

Smooth self‑leveling flow with minimal troweling

Firm bonding on concrete, screed, or existing substrates

Refined finish without pinholes or surface waves

Faster application · Reduced labor cost

Uniform internal structure · Anti‑bleeding formulation

Bubble‑free finish through efficient defoamer technology
