The article describes typical damages of the facing layer from the slit ceramic brick in multilayered wall. It was found that the use of increased strength mortars for masonry of the facing layer leads to an increase of tensile and shear stresses in the brick at the temperature and humidity actions. It is shown that the mortar of the facing layer should be sufficiently strong in compression and still enough plastic. Low- strength mineral mortars have a low modulus of elasticity which increases the masonry crack growth resistance in temperature and humidity actions. Recommendations on increase crack growth resistance of facing layer have been presented
