It really depends on the results you get after the first coat. The purpose of primer is to lay down a surface that is uniform and consistent in

  • color, within reason
  • smoothness
  • texture
  • absorption
  • absence of surface contamination

Because if those things are not uniform, the irregularities will print through when you topcoat.

You can get it to stop printing through if you spam enough coats of topcoat... But since that's primer's job, it's better to resolve it at the primer stage, where you are sure to get it in 1 or 2.

You only ever need 1 coat of primer. Many times you'll need 2 (or 3 or even more) coats of paint to get good coverage, depending on the color, but priming is only done once.

On existing walls that currently have paint, you may not even need a primer coat - especially with all of the paint+primer products out there now.

Does Zinsser primer need two coats?

Generally speaking, primer + paint is a bit misleading. All paint (even older paint not billed as having primer) contains the polymers to "stick" to each other (premium paints contain more of them so, in theory, it takes less coats). The catch there is that paint itself is not cheap (you're using a final coating product as an undercoat).

For new drywall, primer is really essential. New drywall is pretty porous (it will absorb more of the paint than a previously painted wall would) and primer helps fill that in before you paint. The good news is that they make a "new drywall only" primer (example) that's pretty cheap (compared to a bucket of normal paint) because it's only trying to fill that porous-ness, not do other things normal primer does, like provide adhesion over something like an oil/wallpaper glue stain.

I always prime with a quality primer , use cheap stuff & you pay in the long run using more topcoat than primer. especially an older house with plaster walls , depending the last time it was painted , you will see the walls "sucking " in the paint ,only sending you for more paint. It can become an expensive project , I always prime new drywall and especially the spackeling ,this uses a few coats . I laughed when they started advertising "paint with primer", like it magically seals the walls ,lol

Zinsser was founded in 1849 and had been dominating the primer and related materials market for more than 150 + years!

Zinsser is based on 3 principles which are Innovation, Quality, and Problem Solving.

One of the unique aspects of this brand is that it listens to real-world problems and brings cutting-edge features like low VOC and patented BIN primer ranges.

When Can I Paint Over Zinsser Primer?

Like most of the other latex primers, Zinsser takes around 35 to 50 minutes to reach the level of touch dry.

  • Wait until the primer dries properly.
  • Good to wait up to 3 hours for this
  • Some of the factors which can increase these drying times are High Humidity and colder temperatures.

Total time requirements for Zinsser Primer 

  • BIN Patent Primer by Zinsser can feel dry to touch within 20 minutes, and one can recoat it easily within the next 45 minutes.
  • In the next 1 to 3 days, dry primer develops completely and is liable to cure after developing full adhesion.

Zinsser Primer and Requirements of coats

  • As with any other primer, one to two coats of primers are more than enough when it comes to interior walls.
  • However, do keep in mind that the quality of paint, wall material, etc., will also suffice the number of coats and change them accordingly.
  • Read the magic number for any new interior painting projects on the Zinsser website for guessing the no. of coats.

The period between paint and priming

  • As we know that latex primers do their job pretty quickly and require less than an hour to dry out.
  • As per the experts, waiting for three to four hours before any next painting coat is ideal.
  • While the oil-based primers need a longer time to dry out.
  • Give 24 hours at least before giving another coat.

Coats of primer for covering dark paint

Two coats of primer are enough to cover or use light paint to cover the dark paint.

However, doing this via primer is the best method.

Primer helps achieve the same tendency and exact shade one desires.

Thinning the Zinsser 123 primes

Some people might not like the thick consistency of Zinsser 123 and prefer to thin it but may not know the proper method to do so.

  • Firstly, the recommendation is to use the primer without any thinning whatsoever.
  • However, if you still want to thin it, never add more than 10% clean water.
  • Stir the above mixture thoroughly.

Note that thinning primers reduce their stain blocking properties.

PS – For cleaning the primer application tools, simply put them in warm water and some liquid detergent/ cleaner.

Using water-based paint over an oil-based primer

As per recommendations from an expert, oil-based paint must go only with an oil-based primer.

Not only this, your paint can peel off later as well.

So, use only an oil-based primer over an oil-based top coating.

However, one can easily use water-based paint as a topcoat in this scenario.

Shelf life of Zinsser’s Bull’s eye 1-2-3- primer 

Zinsser’s bulls eyes have 3 years to 5 years shelf life which is industry-leading, and It dries quickly for a long-lasting finish.

It ages better than its competitors.

Some other questions,

Q1.) Do one needs 2 coats of paint if they use a primer?

Answer: One of the different thinking mechanisms is there.

Use one coat of primer with one coat of paint.

Q2.) What is likely the difference between Zinsser 123 & Zinsser 123+?

Answer: It is a primer-sealer and stain killer.

It is a fast-drying and whitish acrylic-based latex.

The Zinnser Bulls Eye 123 has multi-utility like the exterior, interior, and old or new paint jobs.

Q4.) Should we sand the walls with priming before painting?

Answer: Yes, sanding the primer is a nice option.

It makes it ultra-smooth and evens the texture.

Use fine #220-grit sandpaper to prevent any extra primer lay-off.

Q5.) How many coats of primer for painting the cabinets?

Answer: Give 2 coats to each door and about 1 sanding session between each of the coats.

The first coat of primer may not cover the cabinets entirely.

Q6.) Is Zinsser a good primer or not? Why?

Answer: The whole house primer and sealer Zinsser 123 is an excellent product for any kind of adhesion.

One more good thing about Zinsser 123 is that it works fine with any oil/ latex paint.

Q8.) Can we call Zinsser 123 as oil based primer?

Answer: Yes

Due to this unique formulation, the use of 123 primer increases manifolds on surfaces like latex topcoats.

The oil-based formula seals any water, smoke, nicotine, and tannin leaks.

Q9.) Do we need a perfect primer?

Answer: While the priming should not be an over-hype process, it should still cover all naked spots.

There should be no visible unevenness.

The main idea here is to get a uniform surface of the wall, which absorbs minimal paint and gives off a better finish.

Q10.) Should we do any kind of sand after priming?

Answer: Yes

  • It keeps the surface smooth
  • Eliminates any odd brush marks
  • Even eliminates the small little globs
  • Sandpaper also helps eliminates any little fibers coming out from the wall

Q11.) What is likely to happen if one recoats the latex paint way too soon?

Answer: The most common happenings in such a scenario is paint pulling up as one rolls.

Or worst, some streaks and uneven peeling can be there.

So, wait properly.

Q12.) How long should one wait for the drying of the primer before final sanding?

Answer: Wait for 7 to 12 minutes to let the coat dry and apply 2 to 4 coats.

As per the expert’s recommendation, Let the primer dry for 60 minutes before any kind of dry sanding.

Test in some side areas to make sure you can proceed.

Q13.) How many coats of paint is the upper limit?

Answer: 2

Q14.) Should one cut it with each coat of paint?

Answer: Yes

While one layer of painting is more than enough in most cases, one does not want to see that the finish is poor after the first coat of paint.

Q15.) Does Zinsser primer need to be stirred properly before application?

Answer: A good stir to your primer is necessary before its applications, so go and grab a stick.

This helps in maintaining a uniform texture.

Q16.) How much is the thickness of Zinsser Bull’s eye primer?

Answer:  The Zinsser Bull’s eye primer 1-2-3 is quite thick in its consistency.

A few people may not appreciate the thickness, but the recent versions are of more uniform textures.

Q17.) Should one roll or brush a primer?

Answer: Primer makes up for a smooth foundation, so as a pro tip, it is a good idea to first apply the brush and then cut it in on the edges.

As the last step, use the roller to fill the surface.

Answer: It is plain simple; use synthetic brushes like poly-nylon or polyester blends.

While the brushes suggested above are perfect for any kind of paintings, but they go best with Acrylic or Latex.

Final verdict 

Zinsser’s has been a legacy for over 150 years in primer and related products.

Founded by William Zinsser, the company stands true on the principle of problem-solving till today.

The brand regularly takes input from the leading contractors around the state and brings innovation.

Primer is the most significant part of the painting process. One should take a good-quality primer.

Priming has many benefits; it uniformly fills all the gaps in walls and helps paint to look out with more finish.

Zinsser’s priming capabilities have been known for many years as it sells one of the industry-leading shelf life holder primers.

Priming needs double coats at the most and can reduce paint wastages and hold paint better.

One can do priming via DIY methods, as you just need a basic brush and a roller, to begin with.

Proper timing is key to everything. Usually, primer from the Zinsser’s can dry as early as 20 minutes.

However, waiting for 24 hours to apply the paint layer is ideal as it dries completely by then reducing any wastage.

Remember that more humidity and colder temperatures mean more time needed for drying primer and paint.

Use your conditions and adjust the timings for yourself or, if unsure, apply the coat to an inconspicuous area.

Thanks for reading!

How many coats of Zinsser primer should I use?

In most cases only one coat is necessary to prime most surfaces. If excessive absorption occurs over very porous substrates a second coat may be necessary. Spot priming is recommended only under high-hiding topcoat finishes. For best results, prime entire surface before painting.

How do I know if I need a second coat of primer?

If you're unsure about how many coats of primer you need for the surface you're painting, a paint store can advise you. Otherwise, start with one coat and check the surface after it dries. If it still looks rough, porous or heavily colored, apply another coat.

What happens if you only use one coat of primer?

This is because the primer won't be able to completely eliminate that dark shade. For example, if you have a dark brown wall and you put one coat of primer. The final paint job will have a much darker shade than when you first bought it. This can ruin the entire project and even cost you some money.

Does Zinsser primer need a top coat?

Primer is not formulated to stand up to the elements and should be topcoated within several weeks to ensure proper bonding. If left uncovered for an extended period of time, primer will tend to deteriorate and chalk, which could prevent future coats of paint from adhering properly.
