Thanks very much for your advice. It sounds like I need to strip back and start again with one of the systems that you recommend. It’s a tiny bathroom, with a wet room floor (ie no shower tray) which drains to a sump that’s then pumped out once done, so not permanently wet.

Can I ask for advice on what top coat paint people would recommend for a wet bathroom floor? Rust had come through the previous one, which I’ve sanded back and treated and now primed ready for painting. It doesn’t need to be particularly slip resistant though that would be beneficial.
