Gypsum Retarder is a chemical additive utilized in the construction and building industry to regulate and delay thesetting time of gypsum-based materials, such as gypsum plaster and gypsum board compounds. By slowing down thesetting process, it extends the working time of the material, facilitating proper application and finishing. This additiveimproves the workability of gypsum materials, allowing for smoother application and reducing the likelihood of
premature setting, which can result in uneven surfaces or imperfections.
