Add just enough water to the cement to form a thick paste. Moisten the old concrete along the hairline crack with water for several hours before adding the grout. Moistening the concrete prevents it from drawing the water from the grout, which will dry out the mixture.
What stops water coming down the chimney?
The chimney crown covers the top of the chimney to help protect it from the elements. The slanted crown should provide a downward slope that will allow for water runoff. This portion of the chimney prevents water from entering the flue, but also prevents wear and tear on the masonry.
