A few key points. 1) this stuff is toxic and can hurt you or worse (be 100% sure you buy respirator and have fresh air blown in) and only do it in unoccupied unit. maybe worst (toxic) stuff I have worked with residentially... bugs were dropping dead by the window...2) no it is not forever permanent--but what it is. 3) prep, prep, and more prep. 4) I would use it on a surround that gets some water splash--not where it gets constant water or submersed (like actual tub, need heavy duty stuff there). 5) follow all instructions and research well....cheap (25-30 bucks + roller)--but a lot of prep labor. it would make the surround look nice enough for the sale and/or get you through a few tenancies on a shoestring until you or someone replaces it.

The main thing you need to work safely with the interior variety is to set up box fans (I use two of the popular Lasko Wind Machines) for forced ventilation, but you should also wear a reusable respirator with VOC cartridges.

Make sure you have a proper respirator that can filter the particulates for your sprayer.I have a Graco model and I use it for exterior painting, interior trim, and for priming the walls. 

Guys with space suits and respirators are expensive--if you are determined to remove any and all lead or asbestos, figure that expense into your pro forma.Disclosure:  I am not a certified lead paint remediator, nor an asbestos abator. 

Seal walls with B-I-NI’ve mopped the walls of the main room with OdoBan & will continue to do so, but if this step is redundant I’d like to skip it because even WITH a respirator my lungs are not happy campers.

Most vermiculite (attic insulation) popcorn ceilings and such just don't pose enough of a risk to worry about.So, I sprayed the ceiling with water, put on a painter's suit and a respirator and scrapped the ceiling in about half an hour.

Get yourself an N-95 filtration respirator.

- The painters are to be covered in protective gear, wear protective eyewear, and have mouth sealing respirators with HEPA filters on them

If so, use your head and wear goggles, gloves, a respirator, etc. and do it on the outside panel so you're not inside with the fumes.

I'm a cheap SOB, so I'd have respirator & gloves and be swearing the whole efin time :DDon't wait too long!
