Bostik MC250 Vitri-Flex is a fast setting, thin or thick bed adhesive. It is suitable for bonding ceramic tiles, quarry tiles, porcelain, vitrified tiles, natural stone and mosaics to walls and floors.

Bostik MC250 Vitri-Flex is formulated for fast track installation and enables tiles to be grouted approx. 2 to 3 hours after fixing depending on conditions. Bostik MC250 Vitri-Flex provides excellent grip and adhesion.

Bostik MC250 Vitri-Flex is suitable for most interior and exterior installations including more demanding installations, such as use with underfloor heating and areas subject to limited vibration. When fully cured the adhesive is suitable for permanently wet areas such as showers and swimming pools. It will bond to concrete, plaster, sand/cement render and screeds, blockwork, brickwork, glazed surfaces, vinyl tiles and plywood overlay.

Sufficiently flat to permit the specified flatness of finished tiling, bearing in mind the permissible minimum and maximum thickness of the bedding material.

Suitable for tiling in the service conditions to which it will be exposed.

Sufficiently strong and rigid to support the tile finish.
