The cracks formed in the crown area cause many difficulties in treatment as compared to the vertical section of the chimney. The water, snow, and ice are present there and move inside from this point. If the ratio of cracks is 1:4 then it also becomes the source of moisture entrance. They are treated with a mixture of pre-mixed cement and mortar. It is applied by squeezing the bottle, which forces the material into the cracks.
