What Is Self-Leveling Compound?

Self-leveling compound is a high-fluidity cementitious or gypsum-based material used to create smooth and flat floor surfaces before installing:

Tiles
Vinyl flooring
Wood flooring
Epoxy coatings
Carpet

Unlike traditional mortar, self-leveling mortar requires precise rheology control, high flowability, and controlled setting behavior — which heavily depend on advanced chemical additives.

Key Performance Requirements for Self-Leveling Mortar

A high-quality self-leveling system must achieve:

✅ High flow without segregation
✅ Excellent self-smoothing ability
✅ Controlled setting time
✅ High early strength
✅ Low shrinkage
✅ Crack resistance
✅ Smooth, bubble-free surface

These properties are achieved through optimized additive systems.

Core Additives for Self-Leveling Compound

Polycarboxylate Superplasticizer (PCE)

PCE is the most critical additive in self-leveling mortar.

Significantly reduces water demand
Improves fluidity and flow spread
Enhances particle dispersion
Increases early and final strength
Maintains slump retention

Michem provides high-performance PCE designed specifically for dry mix self-leveling systems.

Cellulose Ether (Low Viscosity HPMC / HEMC)

In self-leveling mortar, low-viscosity cellulose ether is used for stability control.

Prevents bleeding and segregation
Controls water retention
Improves surface finish
Stabilizes cement hydration

Special low-dosage grades are recommended to avoid affecting flow.

Redispersible Polymer Powder(RDP)

RDP enhances flexibility and bonding performance.

Improved adhesion to concrete substrates
Enhanced flexibility and impact resistance
Reduced cracking risk
Improved abrasion resistance

Especially important in thin-layer applications and renovation projects.

Defoamer Powder

Essential for smooth surface finish.

Reduces air bubbles
Improves surface density
Prevents pinholes
Enhances mechanical strength

Retarder / Setting Time Controller

Used to adjust working time and setting profile.

Extends workable time
Prevents flash setting
Ensures stable performance under varying temperatures

General FAQs

Frequently Asked Questions Questions

What is the most important additive in self-leveling mortar?

Polycarboxylate superplasticizer (PCE) is the most critical component for achieving high flowability.

Why use low-viscosity HPMC in self-leveling?

It stabilizes the system and prevents segregation without reducing flow.

Is RDP necessary in self-leveling compound?

RDP improves bonding strength, flexibility, and crack resistance, especially in thin-layer systems.

Can Michem provide formulation guidance?

Yes. We provide technical consultation to optimize performance for your local market.

Do you supply additives for both cement and gypsum systems?

Yes, we offer compatible additive systems for both types.

What is Hydroxyethyl Cellulose price per kg?

Hydroxyethyl Cellulose pricing depends on:

Viscosity grade: Higher viscosity = higher price
Purity level: Industrial vs. cosmetic vs. pharmaceutical grade
Order volume: Bulk orders (FCL) receive significant discounts
Customization: Special particle sizes or packaging

Price Range (2024):

Industrial Grade: $3.50-5.50/kg
Cosmetic Grade: $5.50-8.00/kg
Pharmaceutical Grade: $8.00-15.00/kg
