Tiles removed, walls smell of urine

[emmavix]

Hi

I'm sorry, this is a weird query. We've removed some tiles in a bathroom that was once part of a cowshed and there's a distinct smell of wee. I'm planning to aquaboard (was going to do this over tiles but they were bulging & on inspection, they pulled off by hand!). I'm leaving the walls to dry out but should I do anything else?

Thanks

Em

You can get urine odour neutraliser from janitorial supply places.

Normally I'd suggest

but maybe you need this stuff intended for sewage farms (if it's decades of cow wee in the walls)
