I am opening an in-ground pool at our new house for the first time, and the chemicals are going well, but no swim time has happened yet as I'm waiting on CYA to dissolve to start shocking. The pool is gunite, approximately kidney bean shaped, and appears to be 30-40 years old. The deck surface feels very rough, like it hasn't weathered well (I can be pretty sure the previous owners did no preventative maintenance or treatment), but is also heaving and cracked in places. I don't have good pictures of the cracking yet, so I'll hold off asking about possible fixes, but I'm wondering about the surface - is there something I can paint on that will make it less rough? Does concrete sealant change the texture, or just make it less permeable?
Picture is attached of an area of the deck. Thanks for any advice.
