I bought my house last year and there is a plaster pool in the back yard. We opened and used the pool last year but noticed that there were a few vertical cracks along the pool walls. I've had a few pool companies out to look at them this year and was told that the plaster looks really new. I can't find anyone to repair the cracks the proper way we want, so I'm wondering if anyone has had any experience with the hydraulic cement? If you "V" out the crack and put this in there, can you put plaster over the top of it? We were losing some water last year, never did a leak test. It's mainly a cosmetic issue that we would like to fix or maybe these cracks are issues if the pool was recently re plastered? I can"t find out who or when the plaster job was done, previous owners will not return any calls or emails from the Realtor. Any recommendations on what's the best way to fix these cracks without just putting some silicon or something on there? I'd rather do something that we can plaster over to make it look decent. I can post some pictures later on or tomorrow.
