mikroplaster

Mikroplaster is a term used in the construction and decorative finishing industries to denote a plaster coating formulated with very fine, micron-scale aggregates to achieve a thin, smooth surface. It is typically applied in thin coats, often around 0.5 to 2 millimeters thick, and can be based on cementitious, lime-based, or polymer-modified binders, depending on the product and intended use. The coating is often marketed in variants that align with microcement or decorative micro plaster categories, with formulations designed for interior and sometimes exterior applications.

Composition and variants commonly include a binder matrix (cementitious or lime-based), very fine mineral aggregates, and optional polymer additives to improve adhesion, flexibility, and water resistance. Some products are pigmented or paired with texturing agents to create specific finishes. Because formulations vary by manufacturer, performance characteristics such as hardness, elasticity, and permeability can differ accordingly.

Application and performance requirements emphasize substrate preparation, priming, and controlled curing. Substrates should be sound, clean, and suitably prepared; mikroplaster is typically applied in one or two coats with a trowel or spray technique and finished to the desired smoothness or texture. Proper curing and protection from rapid drying are important to minimize cracking or debonding.

Advantages of mikroplaster include a very thin profile, uniform finish, and suitability for modern, seamless walls that are ready for painting or sealing. Limitations involve the need for skilled workmanship, substrate movement risks, and sensitivity to improper curing or moisture. The term is often used interchangeably with microcement in marketing but may refer to different formulations depending on the producer.
