LANDU Self‑Leveling Mortar Additives

Precision Flow · Seamless Surface · Enduring Floor Strength

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

LANDU Self‑Leveling Mortar Additive System

Our integrated additive series addresses every requirement of self‑leveling mortar formulation — from workability to long‑term durability.

01
LANDERCOLL HPMC HEMC
Core Control
Cellulose Ether

HPMC / HEMC

Core Control for Flow and Water Retention

LANDERCOLL® HPMC / HEMC enhances rheology and maintains moisture throughout the hydration process — a crucial factor in self‑leveling cement formulations.

  • ✓ Improves flow and leveling performance
  • ✓ Prevents water separation and segregation
  • ✓ Extends open time for smoother application

(Essential HPMC additive for self‑leveling mortar.)

02
Redispersible Polymer Powder

RDP 5100L

Strength, Flexibility & Surface Cohesion

ACCURATE™ RDP 5100L improves adhesion, surface hardness, and elasticity in self‑leveling flooring systems.

  • ✓ Enhances bond between substrate and cement layer
  • ✓ Provides flexibility to handle temperature changes
  • ✓ Boosts abrasion resistance · anti‑crack performance

(A vital RDP additive for self‑leveling mortar toughness.)

PCE Superplasticizer

PCE 580P

Maximum Flow Efficiency at Low Water Ratios

NOVASTAR™ PCE 580P powder achieves exceptional fluidity and control without compromising cohesion — ideal for dry‑mix self‑leveling mortar formulations.

  • ✓ Superior dispersion and water reduction
  • ✓ Uniform strength development and surface density
  • ✓ Applicable for both automatic and manual mixing lines
04
Silicone Hydrophobic Powder

SHP 80

Moisture Resistance for High‑Traffic Areas

NOVASTAR™ SHP 80 creates a nano‑scale hydrophobic barrier that enhances moisture protection and stain resistance in self‑leveling floors.

  • ✓ Excellent water repellency and chemical stability
  • ✓ Improved abrasion resistance
  • ✓ Long‑term durability for wet environments

Defoamer P805
Zero-Bubble
Defoamer

P805

Perfect Surface, Zero‑Bubble Finish

LANDU P805 Defoamer acts immediately during mixing, releasing trapped air to ensure bubble‑free and mirror‑smooth finishes.

  • ✓ Rapid and long‑lasting defoaming power
  • ✓ Prevents pinholes and surface blistering
  • ✓ Fully compatible with PCE & RDP additive systems

FAQ · Self‑Leveling Mortar Technical Insights

Expert answers to common self-leveling mortar questions

Q1

What defines high‑quality self‑leveling mortar?

+

Stable flow, smooth finish, low shrinkage, and no segregation after curing.

Q2

Why do cracks appear in self‑leveling cement?

+

Improper balance of water retention or polymer additive — use HPMC K100 and RDP 5100L to correct.

Q3

What's the standard layer thickness?

+

3 – 10 mm; add more RDP and adjust PCE dosage for thicker application.

Q4

How to avoid bubbles or pinholes?

+

Include Defoamer P805, use balanced mixing, avoid excessive water.

Q5

Does polymer powder improve surface finish?

+

Yes — improves density, flexibility, and abrasion resistance.

Q6

Why choose PCE 580P powder type?

+

Superior storage life and compatibility for dry‑mix mortar production.
