While many middle-men were vaporized by that internet phenomenon; travel brokers, traders, insurance, etc., Realtors® and mortgage brokers have gone unscathed thus far.

Ideally, you would now prime the wall with two coats of oil-based primer like Kilz Original while wearing a respirator equipped with organic vapor cartridgessIf that doesn't work, the plaster or drywall has to be replaced, with all the mess and expense involved.

Slab vapor barriers can be problematic. 

May very easily have nothing to do with a "leak".Concrete is porous, and air, water, water vapor, etc., will travel through it.

Is paint vapor permeability a concern? 

My personal vaporizer has been a life-saver!

Also, the crawlspace needs to be cleaned and have a vapor barrier properly installed along with insulation.

Some people think doctors are evil and tumors melt away with herbal drinks in the vitamix, and that we somehow are trying to BS people and the internet knows better, haha.

I have two exterior walls that need insulation. one particular wall has just the studs and the bricks behind them, so no way of putting sheeting/tar paper/vapor barrier, etc.so, i am thinking of just putting sprayfoam.is there a place online where i can buy supplies so that my contractor can do it?
