According to this page from the SW site this is the ProMar 400 Zero VOC Interior Latex Paint info listed. And it would be a custom mixed color as the label states. SW color matched should match the BM perfectly as computerized color matching is very accurate these days (especially the major brands).

My concern now is that I have a contractor grade flat paint with no primer being put on beforehand on new drywall in my kitchen and bathroom and several other locations throughout the house.

Was primer specified in the contract? Some painters use flat paint directly on the drywall with no primer.

this is just for one small area basically the entire upper for my house has all new ceilings and walls.

2 SF 0.37+ 1.72 = 0.26 4.00 23.95

51. PNT S- + Seal the ceiling w/PVA primer - one coat

C 9.42 SF 0.00+ 0.43 = 0.02 0.82 4.89

52. PNT P2 + Paint the walls and ceiling - two coats

WC 118.76 SF

Is there a chance they took the primer after using it?

The scope of work calls for this throughout the house. I copied and pasted the first thing I came to. Each area throughout my entire house states the same thing just different sizes of rooms and closets.

I guess there's always a chance they took the primer but somehow I doubt. We go over everyday after work and take pictures of what they've done. I would think if they put primer on, it would need at least a day to painted on throughout the house and let it dry so they could paint. thanks for everyone's input this has been a really tough thing for us and the contractor has left a lot to be desired. We had to oak trees fall on the house and had to have 15 new trusses put in plus the majority of our upstairs was destroyed and gutted. This happened back in May and we just got our roof replaced 2 weeks ago.

That is definitely interior Flat PAINT. In the 5G pail, there's just a little "B" (Black) colorant, that's it.

Most likely it was separately primed with whatever cheap-crap primer they travel with.
