Masonry mortar for thin joints for cellular concrete in winter is intended for erecting walls using the thin-layer method of gluing walls with a cellular concrete block. Especially recommended for work in mild winter conditions, at temperatures close to but not lower than 0 C. It can also be used to build bricks, blocks and other ceramic and concrete materials of this type.

properties

Masonry mortar for thin joints for cellular concrete in winter is prepared in the form of a dry mixture of hydraulic binders, selected mineral aggregates and admixtures improving technical parameters and operational properties. The mortar is frosty and waterproof. Prevents the formation of thermal bridges at the joints between masonry elements.
