my in-laws asked me to do a small repair for an in-ground pool, top suction area.
the pool is a standard gunite diamondbrite finish and the pool cleaner goes into an opening cavity on the very top at water level, into a small round pool where the main suction line exists (another is on the bottom of pool)
in the small round area, there is a small crack in the cement right above the water line or just at the waterline
I have to drain the pool a little but am asking what type of cement to use to repair this crack as it will be exposed to the pool chemicals though most of it is above water level. none of this is the actual swimming pool, it's the small round hole outside the pool wall, about 1 foot away from the wall of the pool and exists only for the top suction line into the pool pump
