Typically, one coat of primer is sufficient for most wall surfaces. However, if you're covering dark colors, stains, or new drywall, two coats may be necessary for better coverage and adhesion. Ensure the primer is fully dry between coats for optimal results. For more insights, check out my Quora Profile!

Yes, definitely do some light sanding after a primer coat. I've painted a lot of furniture and there is a definite difference if you don't sand between coats. (Unless you're using chalk paint. Just go for it, no sanding required.)
Most latex primers dry to the touch in 30 minutes to one hour. But for best results, don't paint until the primer completely dries—which can take up to 3 hours, depending on temperature and humidity. Once the primer is completely dry, it's prime time for painting.
Can you paint over primer without sanding the car? Technically, yes, you can do that. Some circumstances don't require sanding the existing paint and primer before repainting. If you choose this route, the car's surface might show minimal damage like puncture holes, body scratches, dents, and cracks.
It's recommended to wait at least 24 hours before adding a coat of paint over your primer. Painting over it soon could cause your paint to adhere to the wall improperly, flaking and peeling.

Overall, it is viewed as a cost-effective solution for priming and sealing surfaces before painting. Great product!! [This review was collected as part of a promotion.] My project would not have turned out so well without using Kilz.
Primer actually covers less area than paint does, at about 200 to 300 square feet per gallon. For a small room of 400 square feet, you'd need 2 gallons of primer. A good rule of thumb is to divide the total square footage of what you're painting by 200 to know how much primer you need to buy.
Generally speaking, you should leave around two to three hours between coats of primer, but always check the primer can's instructions to be sure. It is a good idea to not use any more than three coats of primer when painting to avoid a thick undercoat that doesn't dry properly, leading to cracking or chipping.

Primer is not meant to look perfect, ever. It's whole job is to seal the surface, and it does that job in one coat 98% of the time. If the wall was previously painted and its not a super dark color like greens, reds, and blues primer is absolutely not necessary especially two coats.
After the primer dries, lightly sand away bumps and ridges using very fine grit sandpaper folded into quarters. When the grit of one section of sandpaper becomes covered with dust, switch to an unused section and continue. Wipe the wall clean with a damp towel or sponge and allow it to dry before painting.

Editor's tip: As it's wise to wait a bit between applying your moisturizer and primer, you should also allow your primer time to dry down before applying the rest of your makeup. We suggest letting the primer sit for at least 30 seconds—or until it's no longer “tacky”—before reaching for your foundation and concealer.
For most new drywall, two coats of primer are enough.
The first coat seals the surface, while the second evens things out. This gives you a good base for your paint job.
If you want to prep polyester primer in order to prime over it with another material, start block sanding with 80 to break it open and roughly knock the panel down flat and then do the majority of your blocking with 180 grit and finish with either 180 or 220 grit on a DA sander.
