Concrete and Plaster Patch Recommendations

[rkast]

Hey, I'm on my second summer with a pool and I'd like to get some recommendations and tips for products/techniques to repair some DIY plaster and concrete. The pictures show three things I'm looking to resolve:
1. There are a few spots on the bottom of the pool that are circular cracks that I don't want to expand
2. The concrete grouting between the deck and the pool tiles is breaking up in places
3. There are some cracks in the concrete pool deck that I'd like to fill, and in places where rubberized filling was used, it's starting to get brittle and break apart.

Let me know your thoughts on DIY'ing those different jobs or if you think I'm in over my head.

Welcome to TFP.

Putting patches on the circular spots will not stop the delamination causing it. Your plaster is losing adhesion from the bottom.

Similarly, the correct fix for the deck is for a mason to remove the stones, clean out the cracked mortar and relay the stones in Type S mortar. Water is getting into those areas and the concrete and mortar are being broken from winter freeze-thaw cycles. Smearing something on the outside of the cracking area will break apart again.

There is no magic material to put on top of worn plaster or concrete that will make it new again. To make it like new it needs to be removed and replaced with new.
