Polyurea Coating

[redraider2007]

I'm needing to replace my liner and i'm looking into this. It looks like someone will post asking about it every couple of years but there isn't much traffic on it. Has anyone used Polyurea for there liner? Thanks!

Never hear of it. Let's see if this bump helps out.

Looks like there's some success with ponds but it never took off with pools. I'm guessing there is a reason for it, especially with liner costs still very high at the moment.

I also wonder how well the Rhino-Liner like application would hold up in a pool environment.

There are many different polyurea formulations and so the right one needs to be chosen. Depending on your pools structural design, it’s not a guarantee that you can use polyurea in place of a liner. If the entire pool were a continuous concrete structure, then I could see polyurea possibly working. But if you have steel walls and vermiculite base, there’s no way a thin’ish sprayed-on polymer is going to work better than a 30mil thick continuous vinyl liner. And, as @Newdude alluded to, the cost of the polyurea materials to make up that kid of thickness would likely exceed the cost of a liner.

I don’t think you’ll save any money and I’m pretty sure you don’t want to be the guinea pig for this kind of experiment.

I've heard nothing but horror stories about polyurea - I believe it is not meant to be submerged and the chlorine causes it to break down.

I'd say just stick with a liner.
