How to line a concrete slop sink

In our house we have an awesome old concrete slop sink that gets a lot of use! I love it, but at some point in the past it wasn't quite level. Now the concrete is worn in the back corner slightly below the level of the drain, so it never drains all the way (red circle in image). The sink is like 2 inches thick, so I'm not worried about it failing, but the standing water in there gets stinky. I would like to line the sink with something so I force those corners to actually drain, but I have no idea what to use. Is there some kind of resin I could pour along the basin of the sink to regrade the bottom of it? Can I just use mortar or cement (will it stick to existing concrete)? Any suggestions are appreciated! https://imgur.com/a/36yU76r submitted by /u/homininet [link] [comments]
