Gypsum Plaster

Gypsum Plaster
Performance Priorities

Target performance for this application

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

+

Water Retention

Proper water retention prevents rapid moisture loss on absorbent substrates, supports complete gypsum hydration and reduces premature drying.

+

Workability

Good workability makes the plaster easier to mix, spread, level and finish, reducing labor intensity and improving application efficiency.

+

Setting Time Control

Controlled setting time provides sufficient working and finishing time while allowing the plaster to develop strength within the required construction schedule.

+

Sag Resistance

Strong sag resistance keeps fresh plaster stable on vertical surfaces and allows thicker application without slipping or deformation.

+

Adhesion

Reliable adhesion ensures strong bonding between the gypsum plaster and the substrate, reducing hollow areas, peeling and delamination.

+

Crack Resistance

Improved crack resistance minimizes shrinkage cracks during drying and enhances the long-term durability of the plastered surface.

+

Rheology Control

Proper rheology provides balanced viscosity, stability and ease of application while preventing segregation and excessive stickiness.

+

Surface Finish

Good finishing properties help produce a smooth, uniform surface with fewer trowel marks, pinholes and surface defects.

+

Consistency Stability

Stable consistency ensures uniform application performance across different batches, temperatures and construction conditions.

+

Pumpability

For machine-applied gypsum plaster, good pumpability supports smooth material delivery, reduces hose blockage and improves spraying efficiency.

Problem Solving

Common application challenges

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

Short Working Time

The gypsum plaster sets too quickly after mixing, leaving insufficient time for application, leveling and surface finishing.

Poor Water Retention

The plaster loses water rapidly on highly absorbent substrates, causing premature drying, incomplete hydration and reduced application performance.

Poor Workability

The mixed plaster feels sticky, heavy or difficult to spread, increasing labor intensity and making it difficult to achieve a smooth surface.

Sagging and Slumping

Fresh plaster slides or deforms after being applied to vertical walls, especially when applied in thick layers.

Cracking After Drying

Shrinkage cracks appear on the plastered surface during or after drying, reducing surface quality and durability.

Poor Adhesion

The plaster does not bond firmly to the substrate, resulting in hollow areas, peeling or delamination after drying.

Inconsistent Setting Time

Setting time varies between batches or changes significantly with temperature, water quality and raw-material fluctuations, making construction difficult to control.

Surface Roughness and Poor Finish

The plaster surface is difficult to level or polish and may show trowel marks, uneven areas or a coarse final appearance.

Lumping During Mixing

Lumps or unmixed particles form when the powder is added to water, producing an uneven mixture and affecting pumping or manual application.

Low Wet Strength

The freshly applied plaster lacks sufficient body and stability, making it vulnerable to deformation or damage before setting.
