When To Use Primer Paint

Primer paint can also beneficial if youre working with a glossy surface. These tend to be more difficult for paint to lock onto, but a light sandpapering and a coat of primer paint should do the trick to help the paint stick.

Will Paint And Primer In One Save Money
Self-priming paint is restricted to the more expensive premium paint lines. This is important to note because this immediately drives up costs. You cannot go cheap with self-priming paint, even on a per-gallon basis.
Consider these thumbnail estimates:
- Two Coats of Self-Primer: Apply a coat of self-priming paint at $25 per gallon. Let it dry. Apply the second coat of self-priming paint: $25 per gallon again. For an exterior requiring 10 gallons of paint and primer per coat, your tab is $500.
- Primer and Paint: Apply a coat of primer at $12 per gallon. Let it dry. Apply a coat of exterior acrylic latex paint, non-self-priming, at $17 per gallon. When splitting primer and paint quantities down the middle , the grand total is $290. Even if the job requires a second coat of $17-per-gallon paint, the total cost will be $460, which still saves money over the self-priming option.
In the first scenario, you are using expensive, tinted self-priming paint as your primer vs. less expensive real primer. After all, the tint is another factor that drives up paint costs.

- The paint will not stick very well on the object.

Thus, from the above matter, we can conclude that primer plays an essential role in binding the wall or other material with paint. There are many benefits to using a primer before painting your home. Primer can help the paint to adhere better to the surface, which can result in a longer-lasting paint job. It can also help to cover up any previous paint jobs or stains that may be on the surface and can help to reduce the amount of paint needed for the project. If you are thinking about painting your home, it is highly recommended that you use a primer first. Not only will it help the paint to look better, but it will also help to protect the surface of your home from damage.

The paint and its substrate are both factors. Primers of a sort are typically included in modern metal paints, which prepare the surface for painting. The primers and paints sold separately are less expensive in the long run, but Primed Paints mean you may only need one coat of paint.
Applying two coats of Primer Paint to a metal surface is still recommended for the best coverage and uniformity. The adherence may be satisfactory even if you neglected to use a priming coat, provided the surface was clean and the paint was of sufficient quality.
Problem : New Interior Bare Wood
- Prime bare wood with wood primer to seal the thirsty surface, hide imperfections and bind the wood fibers to make the surface more uniform.
- Pro tip: Slower-drying oil-based primers, such as an enamel undercoat primer, provide better adhesion and are easier to sand than water-based primers. Water-based primer is likely to raise the grain of the wood and require more sanding before you apply the topcoat.

Whats The Function Of A Primer
Before we get to the functions of a primer, it is best to know what it is and why professional painters make so much fuss about it.
A primer is also commonly known as an undercoat, and it is the translucent preparatory coating that we put on materials before painting them.
Priming a surface before coloring ensures that the paint grips the material well, thus ensuring its durability and the ultimate protection of your object from the elements.
So, how does a single product help you achieve all these?
How To Use Primer Paint
Applying primer paint isnt a tough task. Heres the breakdown:
- Prep your space by protecting your space. Move furniture out of the way and cover it with dust sheets. Cover flooring with a canvas sheet.
- Inspect your wall for any holes and cracks. Fill these in and sand down once dry.
- Deal with peeling plaster or flaky paint with a piece of fine sandpaper.
- Sponge down your walls with a soap and warm water mixture. Any grease or grime will lead to the primer paint not sticking as well as it should. Rinse off the soap.
- Cover any bits youre not planning to prime with masking tape.
- Time to apply the primer paint. Stir the pot and pour your primer into a paint tray.
- The application process is pretty much the same as painting. First, make sure your walls are dry from your mammoth cleaning session earlier. Next, roll or brush your primer on in the same way you would for the color coat. Wed recommend using a paintbrush for the edges and a roller for the larger centre.
- Leave your primer paint to dry before reaching for the colored coat.
Still confused about whether to prime or not? The honest truth is – you cant really go wrong with priming. If youre starting out on your painting journey or just want to ensure the absolute best finish, prime. Or if in doubt, prime.

The question of whether or not to apply paint primer before the color coat is difficult because everyone, it seems, has a different view on the matter.
Paint manufacturers nearly always recommend that you brush, roll, or spray one or two coats of paint primer since this is in service of producing a better color coat. Paint contractors charging by the hour might recommend a primer. Yet paint contractors charging by the job might lean toward no primer, especially if they include the materials in the cost.

Benefits Of A Primer Coat
Applying primer over new surfaces seals the original material so that the paint doesn’t soak into it, requiring extra coats. Primer also helps to hide joints, or seams, on new drywall, and it prevents bleed-through from knots and other natural blemishes and coloring in the bare wood. Primer with stain-blocking properties seals over mold stains and other discoloration to prevent them from showing through the finish coats of paint. Primer applied to masonry, metal, and many wood surfaces are essential for proper bonding of the paint job.
Primer is usually white but can be other neutral colors. This is to provide a neutral surface to ensure that paint colors show true. There is no need to color the primer itself, but some paint stores will add a small amount of pigment to the primer to make it closer to your final paint color. This is a good idea when the final color is much lighter than the original color of the surface.
Can I Wait A Week To Paint After Priming
You can wait a week to paint over primer, but it is a big stretch. I recommend coloring your surface immediately after the final coat cures to ensure a flawless paint job. If you leave it bare too long, you may have to prime your surface again before painting it. But how long is too long?
Priming a surface takes as much time and energy as painting it, so it is understandable to feel too tired after the task. You can rest for 24 hours, then resume your project, and you will still achieve good results. A week can also work, but since primers formula cannot stand up to the elements, the coat will slowly deteriorate.
The longest you can leave a primer coat unpainted is 30 days, but this time will vary depending on the primer you have. Primer manufacturers always indicate how long you can safely leave their products uncoated, so always read the instructions before using a product.
If unavoidable circumstances push you to leave a primer coat unpainted for one month, worry not because there are two ways to salvage your project:

Few things are worse than finishing up a project just to realize that your paint isnt sticking to the woodwork, walls, plastic, or metal as it should, or the dried project looks more like your kindergartener took a paintbrush to it.
This is where primer comes in, and choosing the right primer is key to a beautifully finished project. If youre looking for more information on the types of primers available and when and where to use each kind, youve come to the right place.
We have also included a helpful FAQ at the end of the article to answer any further questions you may have. Happy priming!
Why Do I Need To Use Primer
Heres the classic definition of boredom — sitting around and watching paint dry.
But if you knew exactly what happens during those minutes and hours when paint morphs from a sloshing liquid into a thin, glossy film, youd be fascinated.
And it has a lot to do with the primer. If whats underneath the paint is not as it should be, the paint will not dry properly. It could look blotchy with an uneven sheen. It may turn out lumpy with brush marks. It could flake off sooner rather than later. Primer creates a smooth and consistent layer for the paint to be spread over and to bind onto. Its a sturdy interface.
Consider the analogy of clothing and underwear. In addition to covering our bodies for modestys sake and warmth in cold weather, clothing adds beauty, style, personality and color to our persons. Paint can be like that. Underwear, on the other hand, functions as an interface between the skin and the clothing. And just as underwear can correct and mold the body so clothing looks better, primer can correct flawed and uneven surfaces so that the paint looks better and wears better.
So now that you know you need primer to get the best results, how do you know which primer to use? That all depends on your choice of paint.

Interior Walls With Stains
Interior walls need to be spot-primed if they have stains, require extensive patching or drywall repairs, or are damaged. Typically, stains on interior walls are caused by water damage, smoke, mildew, and wood tannin bleeding.
To neutralize interior wall stains, use an oil-based stain block primer from Kilz or Zinsser. When you need to seal in heavily stained walls, use a shellac primer or solvent-based primer & sealer. Remember, stain-blockers are best used in rooms with smoke stains or drywall with water damage.
Also, there are instances where priming can only do so much, like if your basement has flooded. In case of moderate or major flooding damage, its often better to replace the damaged drywall.
The Reality Most Of These Products Dont Contain Any Primer
What makes a paint and primer in one? Usually just a higher concentration of solids, which are the materials in a paint that provide what painters call coverage or hiding ability. So, a self-priming paint is just a thicker paint that is more likely to hide the underlying color that youre painting over.
Well, isnt that what you need to do anyway?? Maybe.
A Lesson on Primer
Many people have heard the general advice that you should prime before painting, but they cant tell you why. Paint and primer are not the same. Paint is the fun stuff, the color coat that provides instant gratification when you roll it on and see your vision for your space come to life. But primer gets your wall ready to paint in the first place. Can you skip it? Most of the time, the answer is No. Heres why:
Your paint might not stick to your surface if its not prepped right. Or it might take you way too many coats to get your color nice and solid. Youre taking a massive gamble just to save a step.
