Tekamal MFM 0-1 joint sealing mortar is a ready-made mixture of cement, siliceous sand, special chemical additives and polymeric fibre. Due to its special composition, the mortar has a slight swelling effect, which makes it ideal for a perfect sealing of joints.

It is specifically intended for sealing wide, 3 – 20 mm wide joints in stone walls, but it can also be used for sealing wide joints in other materials, always keeping in mind that siliceous sand is part of the mixture.
