Gypsum putty

Introduction to Gypsum Putty: Composition, Uses, and Market Relevance

Gypsum putty, also known as plaster putty or gypsum-based finishing compound, is a fine, white powder primarily composed of calcined gypsum (calcium sulfate hemihydrate) mixed with specific additives to enhance workability, adhesion, and water retention. When mixed with water, it forms a smooth, workable paste used for filling cracks, leveling surfaces, and providing a base coat for paints and wall coverings. Unlike cement-based putties, gypsum putty offers superior crack resistance, a smoother finish, and faster setting times. It is widely used in interior wall and ceiling finishing, particularly in residential and commercial construction projects across Asia, the Middle East, and Europe. The global gypsum putty market has experienced steady growth, driven by urbanization, rising demand for aesthetic interiors, and the expansion of the construction sector in developing economies. The product is valued for its ease of application, low shrinkage, and compatibility with various substrates such as concrete, brick, and plasterboard.
