4 Key Applications of Gypsum Plaster Retarder

Gypsum-Based Self-Leveling

Mikem’s retarder ensures optimal flow and extended workability for self-leveling floors. By slowing the set time, it allows the material to spread evenly. This results in perfectly flat, smooth surfaces ready for final flooring installations.

Gypsum Plasters

Whether applying gypsum plaster manually or with spray equipment, our retarder provides extra time for flawless finishing. It prevents premature stiffening, helping achieve uniform thickness, sharp edges for both decorative and structural applications.

Gypsum Putty

For filling seams, cracks, or imperfections, Mikem’s retarder keeps joint compounds workable longer. This reduces tool marks, improves adhesion, and minimizes shrinkage cracks, ensuring seamless walls and ceilings before painting or coating.
