The primary area of application for Nafufill EF is levelling roughness and closing pores and cavities on concrete surfaces  which are non-trafficable. However, its composition allows it to be used for a wide range of applications in new and existing buildings, in indoor and outdoor areas, and on concrete or plasterboard. Even old tile coverings can be levelled over in combination with MC-Estribond uni as a bonding agent.

Easy application

The use as a porous and cavity filler places special demands on a fine mortar. Nafufill EF is a smoothening filler that is easy to work with and offers optimum pore sealing due to its fine grading curve and polymer addition. This allows for quick and efficient levelling of large areas with reduced labour. Application can be carried out using steel and hard rubber trowels. The fine structure of Nafufill EF allows for easy levelling  in extremely thin layers. Surface imperfections, such as trowel marks, can be removed by grinding. Partial quantities can also be easily mixed as required.

Use as surface protection

Theextra-fine filler has a high water retention capacity and is resistant to freeze-thaw effects as well as thermal shock. Together with the MC-Color T 21 or MC-Color Flair pure coatings, Nafufill EF can be used as an OS 4 surface protection system. In combination with the flexible coating MC-Color Flex pure, this extra-fine filler is tested and approved as an OS 5a system.
