Thanks All

My trowel skills are not good so when I placed the flat, nearly level concrete floor of my swim pool I was left with features which collect algae and are difficult to clean.

I looked for a self leveling pour down type product but none of the outfits I contacted would use their stuff under water,  mildly salty water at that.

So I’m going to sacrifice pool depth and put down a topping coat of 3000PSI grout ready mix. adhesive solution over the existing surface first.

I can get a 1 yard transit mixer to the site for a thickness of 15/16″ or a 9 yard vehicle with however many yards are correct. They charge at 4 yds min.

What depth of topping coat should I be thinking about?  Its a structural slab under there, 5″ thk with #4 bars 12″ oc both ways. I even thought of Jiffy Seal or some similar foundation damproofing product over the existing slab first , then the topping coat to prevent water loss when new cracks happen as a result of the earthquakes we get around here, Puna Hawaii.

Thank you very much for the advice
