I am a full time math teacher, own my own lawncare business that I spray about 500 customers lawns.  

Some things to consider otherwise:- Paint is likely to outperform stain (in large part due to the pigments) over the long haul- Be cautious when power washing... a lot of damage can be done to the surface very quickly and water can get into places it's not supposed to... consider hand washing with TSP - Be cautious if spraying outdoors... don't want to have the wind carry overspray onto the neighbor's houses, vehicles, or other property (it happens all the time - dryfall paint is one option).  

After that, we'll make and install concrete counter tops, prep for the apron sink installation, spray the cabinets, doors and trim, paint the walls/ceiling, install the doors and then put in the brick floor.That's our plan of action at least.

Will spray new texture tomorrow.Kitchen has been designed, approved, and ordered.

It looks like it was something someone sprayed on.

i sprayed them three times over the course of three days with bleach and painted them with mold killer from depot @30bucks a gallon... they were on bricks in the basement and in the walls above the drop ceiling. 

Maybe mop with a strong bleach solution just to make sure, and spray some up the wall to the water line.

Sprayed the wood and this has taken the odor away.

I filled up the walls with "open cell" spray foam insulation. 

Spray the trim/cabinets with oil based paint.
