Gypsum-Based Self-Leveling Compound

Performance Priorities

Target performance for this application

Explore the functional requirements that guide material selection, product matching, and application testing.

Flowability

High flowability allows the gypsum-based compound to spread under its own weight and form a level floor with minimal manual assistance.

Flow Retention

Good flow retention provides sufficient time for pouring, spreading and connecting adjacent batches without ridges or visible joints.

Setting Time Control

Controlled setting time provides adequate working time while ensuring timely hardening and predictable construction progress.

Segregation Resistance

Proper stability prevents water separation and particle settlement while maintaining the required self-leveling performance.

Water Retention

Controlled water retention supports complete gypsum hydration and prevents rapid moisture loss to absorbent substrates.

Volume Stability

Stable expansion and shrinkage behavior reduces cracking, curling and dimensional changes during drying and curing.

Adhesion

Strong adhesion ensures reliable bonding to the prepared substrate and reduces hollow areas, lifting and delamination.

Air Release

Efficient air release reduces trapped bubbles, pinholes and surface craters, producing a denser and smoother floor.

Surface Smoothness

Good leveling and finishing properties create a uniform surface suitable for installing wood flooring, vinyl, carpet or other floor coverings.

Early Strength and Surface Hardness

Sufficient early strength and hardness allow earlier foot traffic and reduce powdering or damage during subsequent construction.

Problem Solving

Common application challenges

Open each topic to understand common issues and the considerations behind a more stable application result.

Poor Flowability

The mixed compound does not spread smoothly under its own weight, requiring excessive manual leveling and resulting in an uneven floor.

Rapid Flow Loss

The material loses fluidity rapidly after mixing, making it difficult to pour and connect adjacent batches without visible joints.

Uncontrolled Setting Time

The compound sets too quickly or too slowly due to temperature, gypsum quality or additive variations, making construction progress difficult to control.

Segregation and Bleeding

Water separates on the surface while heavier particles settle, causing uneven composition, weak surfaces and inconsistent strength.

Cracking After Drying

Cracks develop during drying because of excessive water, unstable expansion and shrinkage or unsuitable application thickness.

Poor Adhesion

The self-leveling layer does not bond firmly to the substrate, resulting in hollow areas, edge lifting or delamination.

Pinholes and Air Bubbles

Trapped air remains in the fresh compound and forms pinholes, bubbles or small craters on the finished surface.

Surface Powdering

The cured surface remains soft or dusty and may wear away during walking, grinding or subsequent floor installation.

Slow Drying

Excess moisture remains in the self-leveling layer for too long, delaying the installation of flooring materials and increasing project time.

Poor Moisture Resistance

The cured gypsum-based layer softens, loses strength or becomes damaged when exposed to excessive moisture or unsuitable wet environments.
