My parent's place in NH has this 30+ year old concrete 12x26 patio jutting out into the water. There has been some settling. Off the end of the patio the water is about 10 feet deep.
So I'd like some ideas on how to blend in the settling (looks like my father tried it at one time) and making the surface look nice. I'm not too concerned with leveling. I've read about acid staining but I don't want those chemicals in the water.
