I primed my walls with Kilz 2 days ago. I do not plan on painting over these walls for like 1 - 2 weeks due to time issues. Will the Kils smell go away or do I need to paint over it for the smell to go away? Any help would be greatly appreciated.
The "off-gassing" tends to dissipate after about 3-4 days- depending on the ventilation of the house/room.
Just remember to sand before painting- and use a dust mask.
As long as you don't see dust or grit type stuff in the kilz, you don't need to sand. kilz is a flat primer in either base. Yes painting over the kilz will encapsulate the smell,but, of course now it will smell like the new paint for a while.

You don't necessarily need to sand on walls, but a light scuff may be the difference between one or two coats and three or four. Particularly if you have textured walls, there will be a lot of little spots where the paint "beads" off of the dissimilar primer and the white primer shows through. A scuff also helps the overall bond; anyone who has tried to paint over yellowed-enamel on trim with a semi-gloss acrylic can tell you that sanding is a good idea.
If you do decide to sand the entire surface of the walls; make sure that kilz is 100 percent dry and hard as a rock! Read the instructions on the can....it seems that most folks don't.
If you sand, used a pole sander like drywall contractors use. It will go 100 times faster than hand sanding. Use fine or very fine sandpaper. I would use sandpaper, not screens for pre-paint sanding, but some people use screens.
If you want a really perfect looking job, take a very bright light, hold it an inch away from the wall. go over every square foot of the wall and examine it closely. Mark any blemishes, missed spots ect with a pencil. Then spackle, sand, touch up or whatever in those areas until the wall looks perfect under the bright light. Let ist all dry fine sand and paint.
If you want anything close to something that looks somewhat professional (mouthful)- sand!
Drywall repairs or not- if you didn't wash the walls, broom the walls, or in any other way try and clean them before primer- I'm positive they look like crap with a close inspection. And I'm sure you'll find plenty of lint/fibers from the roller (if you used one). If you used a brush, the walls are full of brush marks- all of which make for a less than superior paint job.
Sanding is not a major undertaking- especially when you consider the end result. Use a pole sander and 100 grit paper that's made for the sanding pad. Sand the walls in a vertical direction- at the ceiling line and baseboard you can go horizontally.
After sanding- take a "moist" cloth and wipe away the residual dust, now you're ready to paint with glowing results.
