Cement/Mortar/Gypsum Retarder

Gypsum retarders extend the setting time of gypsum and determine the operational time during the construction or molding process of gypsum based materials.

We are pleased to introduce our Gypsum Retarder, a revolutionary product that extends the setting time of traditional plaster, finishing plaster, lime finishing plaster, and solidifying joint compounds. By slowing down the chemical crystallization that leads to gypsum setting or hardening, our Gypsum Retarder gives you more time to complete each job. Easily dispersible in water before adding gypsum, it is a convenient and effective solution for your construction needs.
