Gypsum Retarder

Gypsum plaster retarder is an additive used to slow down the setting time of gypsum-based plasters. It is especially useful in hot or dry weather conditions, where gypsum plaster might set too quickly, making it difficult to work with and finish smoothly.

Purpose of Gypsum Plaster Retarder:

• Prolongs setting time: Allows for better workability and finishing.
• Improves drying: Provides more time for leveling and smoothing surfaces.
• Prevents cracking: Reduces early drying stresses that can cause surface cracks.

Application:

• Mixed directly into the water used for preparing the plaster.
• Dose varies depending on the required delay (usually around 0.01-0.01% of the gypsum weight).

Benefits:

• Improved working time for plastering, especially in hot climates.
• Better surface finish.
• Reduced surface cracking and shrinkage.
