They oxygenate the urine and break the chemical bonds to destroy it.

Also if that weren't the case there maybe chemicals in the new finish that may have activated the chemicals in the old finish and that is why it isn't curing.

Not the only factor but a big factor.For the one I have I hire out the pool maintenance (chemicals only and filter clean) and split the cost with the tenant 50/50.

I am a student, studying chemical engineering.

I also run an ionizer to get rid of any lingering chemical odors.  

Reglazing a tub won't affect the slope at all as that is not the intent of reglazing, reglazing a tub can be more or less thought of as painting a tub to make it look new again (just done with special chemicals).

We had an inspector check both sides, and based on the severity of the tenant side compared to our side, it was determined that the tenant side was the cause of the infestation.Meaning, the tenants were most likely the source.Three times we have sprayed (ourselves) a chemical called CrossFire.
