Why is the bath still unvented?

It is VERY important...unless it's not used much?!

If it's daily use, get a fan in there...vented to the outside, as is code.

You SHOULD wash the walls down first, preferably with POWDERED Dirtex.
Use a good primer like Zinsser's 123 Latex, or C2-One.

If it won't be vented...primer-type will make no difference. You're just asking for problems then.

Thanks, Faron. It is not a daily use bathroom, but I still wish it were vented. The condo was built in the 40s so there are many things about it that are not up to code. One day when I am able to remodel, that will all change.

I have not had issues with the walls in the bathroom in the past 4 years, with the exception of last month when a burst pipe in the upstairs condo unit and subequent half-a$$ed patching by the condo management led me to decide to it was time to re-patch and paint. :)

So...Wash em down with Dirtex then Zinsser's or C2-One. Sounds good.

Thank you!
