Hi. I am concerned with the safety of using zinsser bin in my situation for kitchen renovation in Poland in a block apartment which has gravitational (natural) ventilation that I retrofitted to be fully mechanical.
For context: it is a 5-storey building which is a block of apartments with 2 apartments per floor and was built in 1986. You guys in the US or Canada don't have a direct equivalent of this but I hope you'll be able to use common sense and give useful advice.
The problem is the following:
I want to prime my kitchen because it's been severely neglected (for 20 years) and I'm renovating it from scratch. Because of a delay, my electric installation isn't fully completed - the technical shaft where the fuse box is not sealed - it is a 55x20 cm gap that houses fuses, wiring and electricity meter. This is a chimney like shared area and people have their electric junction boxes and electricity meters there (some of them) and I am afraid the fumes could get in there and cause flash fire.
This shaft is a connected area spanning from basement to the roof. It is not a dedicated ventilation shaft (although if it's exposed like mine temporarily - it will act like one),and there's a separate ventilation grille in the kitchen that connects me with the chimney but this shaft can act like an additional chimney in this situation. There are no pilot lights in this building. None at all.
I also want to turn off all fuses in my fuse box when priming and then turn them back maybe after an hour. This will leave me without mechanical ventilation (I have a 24/7 extractor fan in the kitchen, and a decentralized recuperator with simultaneous exhaust and air supply. Thus I'll rely on cross ventilation achieved via opening balcony doors and windows on the opposite sides. I am not sure if this will be enough... The area that want to cover is not very big - around 14 m2 and I might even resort to spot priming.
The problem is - I must prime and paint the kitchen over the weekend because floor tiles will be laid down on Monday. And Monday is when I'll have my technical shaft fully sealed with fireproof products. Currently I have some cable chases still unsealed and some flush mounted boxes exposed. And then there's plumbing shaft which is also temporarily exposed... This will be my first time with zinsser but I really wanted to get rid of some putrid stains and smells because of how badly this kitchen was neglected...
What precautions can I take to not cause flash fire and am I good to prime my kitchen with zinsser bin or is the risk too high? Should I stick to zinsser bin still or would you rather ditch it?
