The answer depends on whether a spray texture is going to be applied. A drywall primer/sealer provides an even foundation and uniform porosity for texture or finish. Usually, these are a thin slurry, almost as if you mixed a primer with joint compound. USG makes one. I am more familiar with Hamilton Prep Coat.

For a paint system, a high-quality PVA primer will be fine.

Sorry but PVA primer is garbage. After you have used it your walls will look like nothing was even put on them. Do yourself a favor and use one of the multitude of primers on the market like Benjamin Moore Fresh Start Latex or Sherwin Williams Promar 200 Primer just stay away from PVA

I'm sorry that some painters have had bad experience with PVA primers. Quality ones are engineered with enough pigment to cover thoroughly, provide good adhesion, rust and mildew protection and give a positive seal. My company sells hundreds of thousands of gallons to small and commercial painters, all extremely satisfied with a good product and willing to invest the cost to reduce labor. Buy quality, not the cheapest thing you can get your hands on.

Yes...PVA-class primers are OK at best, but if you used a better primer like Zinsser 123 or C2-One...you'd never go back to the PVA-stuff!!

It's KIND OF like comparing cheap/light painter's-plastic to 6-mil landscaping plastic!

Best Primer for New Drywall?


We are working on an upstairs with 4 bedrooms, 2 baths, hallway & stairs. The bathrooms have all new sheetrock. The rest is painted sheetrock that was NOT primed before it was painted originally. It has various large patched areas (new drywall & mud), plus MANY smaller places where loose paint was removed or/and larger nicks were skim coated and sanded.

The drywall contractor swore by the USG Firstcoat, but after doing one bedroom and the hallway, (2 coats each), I am skeptical.

Is this stuff only good for the new sheetrock areas? How can I tell if it will bond the old and new paint? Why am I needing 2 coats of it? (Covering a dark maroon and dark green paint.)

Had it tinted, so can't return it - I think I want to change to 123.

Manufacturers go to great lengths in naming their products to indicate their inted purpose. "First Coat" is just that; it is not intended for previously painted surfaces. It is intended for new gypsum board surfaces only.

I think in your situation Zinsser 1-2-3 Primer is a better choice. It also has enough pigment load to help covering deep colors.

So should I go over what I have already primed with the 123? Better to do the extra work now than after the paint (I will be using either BM or Muralo - most likely a matte finish.)

My vote is for Zissner 'Cover Coat'. Bar None the best primer I have ever used for drywall priming. Once applied it can be sanded to a feather finish where most latex primers gunk up somewhat.

You probably should put 1-2-3 on everything. This will ensure that the primed surfaces have even porosity/sealing and enable your finish to go on evenly.
