New drywall - so many primer choices
 
I've spent the last several days reading just about every possible post about primers, and I can't say that I've come to any good conclusion.... so I need some help sorting it out.

I have a newly renovated bedroom/closet/bathroom with brand new 1/2" gyp and greenboard in the bathroom. Taped and finished by a professional, it looks pretty good. Now I'm ready to prime.

My plan is to put a light blue eggshell on the walls in the bedroom, and an off-white on the ceilings and walls everywhere else. I'll prime everything first, then lightly sand the primer coat, apply a first coat, lightly sand again then apply the final coat. BUT.. which primer to use is the big question.

I have a good SW store nearby, and I've seen suggestions for Preprite Problock, Promar 200, and Premium Wall and Wood primers. I could use a little guidance to settle on one. It will be rolled, not sprayed, and I'd like to get the best possible looking finish, of course. There are some small imperfections that would be nice to hide, but I'm not going for level 5. Or is SW Drywall Primer the best way to go?

And, do I need to use a different primer in the bathroom with the greenboard? Should I get it tinted for the walls (light blue) or just use a white all around?

Any help would be greatly appreciated.

Priming drywall is one of the most basic duties for primers.
Go with the Drywall Primer- don't tint because you are using light colors and you can use it on all walls/ceilings.
You might want to pick up some lightweight filler in case you see something after prime that needs a bit of mud- paint never fills. Sand and spot prime any of those and 2 full coats quality finish and yer golden!

Primer and paint will not fix the flaws, take the time to fix them before doing anything.
Nothing wrong with the Sherwin Williams products but I just use Zinzeer 123 and never had any issues.
There's no need to tint with that light a color.
Make sure to use flat paint on the ceiling.

Thanks for the great replies! I was planning on eggshell on walls and ceilings, but now the plan is:

Standard SW Drywall Primer, Eggshell on walls, flat on ceiling, satin on trim.

Have I got the right plan?

Thanks again for the quick replies. I appreciate it. Mark

Sounds like a good plan to me. Come back and let us know how it turns out.

First, good for you for educating yourself before starting.

However, what you're suggesting is overkill. You definitely don't need to sand after your first coat of finish paint. You probably don't need to sand after the primer coat either. The reason is that with 2 coats of paint coming, there is enough solids or bulk there to cover any tiny imperfections could cause. Of course it couldn't hurt, especially if there are roller hairs or whatever that have found their way in there. But if you did a decent job, I wouldn't bother.

Now on to your real cost and labor savings. If the drywall finish is good and sanded smooth, you don't really need to use a primer at all if you use 2 coats of a good quality paint. Since you're using eggshell, you will definitely need 2 coats. But with a paint like SuperPaint, 2 coats over bare drywall is fine. Yes, this is acceptable and warranted by Sherwin Williams. (Benjamin Moore is the same way).

I prefer flat in the bedroom, eggshell in the bathroom, and semi-gloss trim, but to each his own. If you prefer the sheen of eggshell in your bedroom that's a personal preference, but you might prefer an "in between sheen" such as Matte, found in SW Duration or BM Aura.

Now I'm even more confused than before.. help! I talked to the painting contractor tonight and told him that I wanted a coat of drywall primer throughout. He said, "You don't need primer... it's just watered down flat paint. Just paint the whole room - ceilings and walls - with flat paint and then put color on the walls. Primer is just a waste of money."

So who is right? I bought a 5'er of SW Drywall Primer and my painter says its totally unnecessary. What do I do??

Help. Please!!

Well I already told you - read my previous post :-)

Of course drywall primer and/or sealer is not just watered down flat paint. But he is correct that drywall primer is often not necessary.

Sherwin Williams SuperPaint is a paint I use often. Read what SW has to say about application

http://www.sherwin-williams.com/docu.../035777036921/

So it is completely warranted and recommended without a primer over drywall. (And yes, satin is the same - 2 coats obviously.)

The contractor is a hack. Primer is primer, made to seal and add a surface for the real paint to stick to. Yes, you could just use the finish paints with multiple coats but look at the cost. The primer is cheaper than the finish coats.I would prime all, paint the ceilings flat, walls matte, trim semi gloss, eggshell for bath and kitchens.

Find a new contractor as soon as possible.

We do this about every 6 months, but let's do it again.

"Real paint" sticks to drywall just fine. The manufacturers agree.

Now as to the cost....

First compare 1 coat of primer and 2 finish coats, with just 2 finish coats. Hopefully this one's obvious - skipping the primer is cheaper.

Now compare a situation that I encounter in the real world with real paint - like Sherwin Williams SuperPaint. Most colors are going to go on in 1 coat. So compare 1 coat of primer and 1 finish coat, with 2 finish coats. Is the primer cheaper now? Not necessarily. Let's say you're painting a master bedroom that's 15x13 with 9' ceilings - pretty typical. This room is too big to cover with 1 gallon - it takes 2. So you need 2 gallons of $15 primer, and 2 gallons of $30 paint, for a total of $90. Guess what? To put on 2 coats of paint takes only 3 gallons, for a total of $90.

Granted, most homeowners can't buy SuperPaint for as low as $30 retail, but there are sales - 20-40% off is not uncommon. Although I haven't used it myself, I've heard reports and seen results of 1 coat coverage with Behr Premium Plus Ultra, and that's in the $30 price range.

And don't forget the added cost and/or cleaning labor of multiple brushes and rollers and roller pans if using separate primer and paint.

And if cost savings is really your bag, then go completely crazy and get 2 gallons of SuperPaint in Flat and just paint 1 coat right over that bare drywall. No, the manufacturer doesn't "warranty" it, but guess what? The paint isn't going to fail, and it is going to work - in most typical colors.

Really don't want to start an argument but I have to totally disagree. I use a lot of super Paint and I think it is a very good paint, especially when it is used as paint. I am not going to do all this prep work then take a chance of flashing on the new mud in the seams and on the corner bead and nail heads. When all I have to do is prime like I contracted to do and I don't have to worry. I feel primer is about the cheapest insurance out there. I am not going to risk my paint job just to save a little bit on primer a product I know will work. I think the last 4 words of you post say a lot.

I was talking about flat paint. Eggshell is going to take a minimum of 2 coats, or primer/sealer and 1 coat to avoid flashing. But the minimum usually works.

I didn't mean them to - since no manufacturer is going to warranty 1 coat over bare drywall. But as a practical matter, it will often work, and anyone can try it out. There's no harm in putting on one coat and seeing what it looks like. If you're happy, you can stop. If not, put on another coat like the manufacturer says.

Brushjockey 01-03-2013 10:07 AM

Sorry Jeff- I do not agree.
A sheened paint, to get full coverage, not just of color but of a sealed enough surface to come to full sheen, takes 3 coats.
You can use all paint, but it is a waste- primer does it better and cheaper.
If you go to touch up a spot on something with 2 coats over raw- the flash will be very dramatic, because the rest of the wall will not be as completely sealed.
There are a couple of exceptions- builders flat, which I would never use for anything, and the highest end paints like Aura. And even with aura I like to prime because is is just better.

And Primer and one coat, even with aura is a bad idea. Seldom works.
