Microcement

Microcement is a cementitious coating designed to create a seamless, continuous surface with a very thin profile. It consists of cement powder combined with polymers, pigments, and fine aggregates. When mixed with water, it forms a smooth paste that can be applied in thin layers (typically 2-3 millimeters) over existing substrates. It adheres to most stable surfaces with proper surface preparation and a suitable primer.

Applications range from floors and walls to countertops and furniture. The typical system involves multiple coats: a primer to promote adhesion, one or more base coats to build up evenness, a final finishing coat, and a sealer to protect the surface. Depending on the product, the finish can be matte, satin, or glossy. Microcement can be installed on concrete, ceramic tile, plaster, cementitious boards, wood, and metal with appropriate preparation.

Advantages include a seamless appearance, minimal thickness, and design versatility, allowing imitation of concrete, plaster, or natural stone. It can be applied over existing substrates, reducing demolition and disposal in renovations. The surface is durable, relatively easy to clean, and adaptable to curved or irregular forms.

Limitations and considerations include the need for skilled installers to prevent cracking from substrate movement, proper surface preparation, and timely sealing. The coating is not inherently waterproof; waterproofing behind the system is required in wet areas. Maintenance depends on the sealer and traffic, with possible need for re-sealing and periodic repairs if damaged.

Maintenance typically involves pH-neutral cleaners and routine resealing every few years. Repairs often require spot touch-ups or reapplication of coatings, followed by resealing. Microcement is commonly used in bathrooms, kitchens, living areas, showers, and commercial interiors.
