ZM-22 Masonry mixture for gas silicate blocks

Masonry mixtures

Glue for thin seam masonry. Manufactured industrially in the form of a dry mixture with mineral binding fillers and agents. After mixing with water forms a homogeneous adhesive mass of grey colour. Prevents the occurrence of thermal bridges in the seams between the elements of buildings. Water resistant. Frost resistant.

Use of masonry mixture for ZM-22 gas silicate blocks

Masonry mortar designed for construction of exterior and interior walls made of cellular concrete blocks (for example - aerated concrete), connected by thin seams. The mixture is also suitable for blockwork of sand-lime blocks (silicate). Furthermore, it can be used inside buildings for leveling and smoothing of walls made of blocks.
