plasterin

Plasterin is a term used in construction and decorative arts to refer to a class of plaster-like materials that extend traditional plaster with modern additives. There is no single, standardized formulation associated with the name; products marketed as plasterin vary in base composition and in the types and amounts of binders, polymers, fibers, and pigments. In practice, plasterin candidates are typically gypsum- or lime-based, sometimes cementitious, and may include acrylic or vinyl polymers to improve adhesion and flexibility.

Forms and uses: Plasterin products are used for interior wall and ceiling coatings, skim coats, decorative plasterwork, and restoration projects. Variants are often designed for rapid setting, moisture resistance, or decorative finishes. They can be formulated for various substrates, including wood lath, masonry, or concrete, and may be offered as pre-mixed putties or as finish plasters to be troweled on.

Application: When prepared, plasterin mixtures are applied by trowel and spread to the desired thickness. They cure by a chemical reaction and gain strength as they dry, with cure rate and workability influenced by temperature and humidity.

Advantages and limitations: Polymer-modified plasterin can offer better adhesion, crack resistance, and stability than traditional plasters, and may reduce shrinkage. Performance depends on substrate compatibility, proper mixing, and environmental conditions; some formulations can be more expensive or moisture-sensitive.

History and terminology: The term plasterin is not a standardized industry designation. It may appear as a generic descriptor, a brand line, or in design literature; practitioners should verify product data sheets for compatibility with substrates or restoration goals.

Safety and environment: Like other plaster products, plasterin dust requires respiratory protection during mixing and sanding. Follow standard construction safety practices, including eye protection and ventilation. See also plaster, gypsum plaster, lime plaster, polymer-modified plaster.
