I finally started rehabbing my pool after years of setbacks. I pretty much knew what I was going to do but ran into an issue. I'll go over everything briefly first. I plan on painting over re-plaster and have an epoxy primer and paint. Don't know if I can name the brand. I have the pool empty and clean. I will wash with TSP and acid wash before I continue. I had some rust spots I chipped out and some cracks I widened. I plan on using hydraulic cement in those. I have a jet where the cracks were more extensive but I still think I can fix that with hydraulic cement. I have flaking up plaster which I will pressure wash, chip, scrape, do what ever to remove. I plan to somewhat smooth the sides with extra hydraulic cement and leave the bottom as is. Where I have a problem is a crack next to the bottom drain. Water flows into the pool with pretty good pressure. I have a cap in the plug attached to 3/4 in pipe and in a photo you can see water flowing from it. I plan to hook a pump to that as soon as my impeller comes in and am hoping I can suck enough out of the drain plug that it doesn't flow out of the crack. My question is what is the best way to fill that crack? I'll post key photos and link to the rest.
