Microcements
Microcements are cementitious, typically with a much higher fineness than a CEMI Portland cement and can be mixed with other constituents such as fine aggregates, polymers, resins and colours. A sealer will be used post application.
Microcement is a coating that has become popular over the last few years in interior and exterior decoration. It can be applied on almost any type of solid substrate, both vertical and horizontal, such as concrete, self-levelling mortar, cement mortar, terrazzo, marble, plaster or plasterboard and tile.
Visually, the finish maybe similar to polished concrete and can be ideal for use in bathrooms, changing rooms and any room where the surface is exposed to moisture or water, including swimming pools. It is usually applied at 2-3mm thick generally on a fiberglass mesh.
Microcements can be categorised under BS EN 13813. Typically, it will be a proprietary product applied in accordance with manufacturer’s instructions and usually requires specialised certified labour.
Microcement is also use in specialist grouts and repair products.
