The dosage of retarder typically ranges from 0.1% to 5% of the total weight of gypsum, but the optimal amount may vary based on specific formulations and desired setting times. Testing is recommended.

Yes, gypsum retarders can be used alongside other additives, such as plasticizers or accelerators, but compatibility should be verified to ensure desired performance outcomes.

Gypsum retarders are especially useful in applications such as intricate moldings, large surface areas, or in conditions that demand extended working time, like during hot weather.

While retarders primarily serve to extend working time, excessive use can lead to reduced final strength or other performance issues, so it’s important to follow recommended guidelines.
