What is a Spray Paint Primer?

Primer is a substance that is used to prepare surfaces for painting. You need to apply primer to difficult surfaces in order to increase their adhesion abilities. Primer can be applied to any painting surface, including canvas, metal, wood, resin, and others. You dont always need a primer, but it always helps to create a smooth surface for enhanced painting. The main purpose of using the best spray paint primer is to allow the paint to stick better to the surface. Primer also helps the paint to have a longer life and will reduce the risk of peeling or chipping. Spray primer is available in a range of different colors. The color you choose should depend on the type of colors you will be poainting with. Lighter primers work well with lighter paints and dark primers work well with darker paints. The most common primer colors are grey and white.

You will also need to choose a primer based on the type of paint being used, and the surface that you are painting.

Why Use a Primer?

If you start painting without applying a coat of primer, it could result in some very bad results. The paint might not properly stick to the surface, and it could easily get damaged or start fading away. Applying primer helps to increase the adhesion of various surfaces which makes the painting process more effective. It will also help to protect the paint from damage.

Primer is not always needed, and you can often get away without using primer spray paint. However, if you do use primer, these are some of the key benefits:

  • Adhesion: The main purpose of applying primer is to increase the adhesion of the surface for the paint. This is particularly important for smooth surfaces that don’t naturally hold paint very well. This should be decided when considering the type of surface and type of paint used over that.
  • Stronger coating: When applying primer, you have a better surface for the paint colors to come through stronger. If you want to get solid colors without any underlying colors or paints showing through, then a primer is a good idea. Applying primer lets the paint colors shine bolder and more clearly. This allows you to create a more striking artwork.
  • Durability: Primer helps the paint to stick, but it also creates a stronger surface for maintaining and protecting the paint. Because the paint will hold better to the primer, the risk of peeling, chipping, or cracking paint is reduced. This allows you to enjoy a longer and more durable paint lifespan. Especially for painted surfaces that a outdoors and exposed to damaging forces, having the best spray paint primer underneath will add good protection.
  • Easier painting: Primer spray paint also helps to make painting much easier. Thanks to the better level of adhesion, you can work faster with fewer issues. Colors come through stronger and there is less run or drip in the paint. This makes it easier to achieve your desired results.



Benefits of a Spray Paint Primer

You can apply the primer with either a paintbrush/roller or by spraying it on. When you spray the primer, there are many benefits to enjoy.

  • A smoother finish: Primer spray allows you to get a perfectly even coating with greater ease. When you brush on primer, you can get brush marks, runs, and drips forming quite easily. However, a spray primer allows you to coat surfaces perfectly evenly. This is particularly useful for detailed surfaces and hard to reach places.
  • Faster drying: A primer spray paint dries much faster than a primer that has been brushed on. This is because the coats are thinner. When you apply a primer, you will have to add a few coats for good results. Spray primer allows you to add more coats much faster thanks to this.
  • Easy to use: The best spray paint primer is just easier to use. You dont have to worry about getting precision brush strokes and painting a perfectly even surface. There are no brushes to clean up, and the job takes quicker. A primer spray offers a far easier user experience.

Different Types of Spray Paint Primer

When considering which primer to use, there are many different options available. Choosing the right spray primer can be difficult because of this. When looking at primers, there are three different types to choose from. Underneath these categories, there are various different products.


Oil-Based Primers

An oil-based spray primer is a versatile option. These primers can be used over quite a wide range of surfaces, and are suitable for oil-based and latex paints. These can be used as a wood primer spray, or over metal, and any interior and exterior surfaces that have already been painted. The reason that this is a great wood primer spray is that it will seal the porous wooden surface. This stops any tannins that are in the wood from releasing and bleeding into the overlying paint. The primer will help to prevent peeling and blistering from occurring.

Oil-based spray primers are durable which makes them a smart choice for outdoor use. Another benefit is that they work very well in covering up stains and marks. However, it is not recommended to use an oil-based spray primer with water-based paint. They also take a long time to dry and can be quite toxic with high levels of VOCs.


Latex Primers

Latex primer is a water-based product that works well over many surfaces. This is one of the best spray paint primer options thanks to its ability to work well with acrylic and water-based paints. This primer can be applied to brick, concrete, unfinished drywall, softwoods, and galvanized metals. Compared to an oil-based primer, latex primer has some benefits. It is more flexible and less brittle, faster to dry, and is less prone to cracking and blistering. Being water-based, the formula is also safer and less toxic to use. Minor stains can be covered up with latex primer. Being water-soluble, this primer is also easy to clean.


Shellac Primer

Shellac primers have their strengths and downfalls. This type of primer works very well for blocking stains and covering up water and smoke damage. Besides blocking old stains, they also work very well for stopping new ones. Shellac primer can be used on wood, metal, plastic, and plaster. They also offer a wider variety of paint options, as they can be used with oil-based or water-based paints.

Shellac primer is super strong bonding and dries fast. However, this primer lacks versatility compared to other primers, and they emit pretty strong fumes which can be harmful. Shellac is also difficult to clean up.



The Best Spray Paint Primer

Now that you have a better understanding of primers, it’s time to take a look at some of the best options available. The primer you choose should depend on the kind of paint you are using, and the surface that you are painting over.

How to Choose the Best Spray Paint Primer

Primers are not all made equal. Choosing the best spray paint primer should depend on the specific job at hand. The type of paint you use and the surface you will be painting over are the two most important considerations.

Spray Primer vs Paint On

The first thing to decide when using a primer is whether you will spray it on or paint it on. Some primers are available in a can that can be applied with a brush or foam roller. This offers you a nice thick coating and is good for application over a large flat surface. The downsides are that painting on a primer like this makes it harder to achieve a perfectly smooth and even coating. You can get brush marks forming, and applying the primer over detailed areas can cover up some details. The best spray can primer is easier to apply. This type of primer helps you to get a more even coating. It is faster to spray on primer, and the layers are thinner which dries faster. If you will be painting a small object, something detailed, or consisting of many curves and lines, then a primer spray paint is best.


The Type of Paint

The next consideration comes down to the type of paint that you will be using. As a general rule, the primer should match your paint. For example, an oil-based primer should be used with oil-based paint, a water-based primer for water-based paint, and so on. This allows the paint and primer to bond properly together.

Choosing paint and primer from the same brand is often a good idea. Always check the primer’s instructions to see if it is compatible with your paint type.


The Surface

When choosing the best spray can primer, you will need to make sure that it is suitable for the type of surface that you will be painting over. Different surfaces are suitable for different primers, so be sure to choose a product that is compatible. A wood primer spray may be completely different from a plastic primer spray paint. Always check to see if the primer you choose works with your surface.


Covering Stains

Sometimes you will be painting over a surface with dark stains on it. If this is the case, you should use a stain-blocking primer to prevent these marks from coming through on the paint finish. Oil-based primers are best for this.


Choosing the Color

Primers are available in a wide range of different colors. The color that you choose should depend on the color of the paint you will be using. Lighter primers suit lighter paints and darker primers suit darker paints. Otherwise, a neutral grey or white primer will work well with any paint colors.



Applying a Spray Can Primer

The best spray paint primers are very easy to use, allowing you to get an even finish with minimal effort. While the application process may differ between products and surfaces, there are a few basic steps to follow.

  • Start by getting your surface ready for the primer. Depending on the surface, you may have to sand it down a bit for a smooth and even finish. Generally, primer cannot be applied over existing finishes on many surfaces. For this reason, you should try to get the surface bare. Old wood may need some sanding to get the wood smooth and ready.
  • Now it’s time to clean the surface. Make sure that the surface is completely cleaned and dried before adding the primer. This will help with adhesion, and avoid any unwanted dust or dirt from getting trapped underneath the primer.
  • When the surface is ready, you can start to apply the primer spray. Hold the primer spray paint at a set distance from the surface and start to spray it on. You can do a test spray on a piece of paper first to make sure that it is spraying well. When you start spraying, be sure to maintain a steady spray movement. If you stop to spray at one point, you will get a buildup of primer in one spot. This can cause drips and runs.
  • Leave the primer to dry, then you can apply the next coat. Sometimes, people will sand down the dried coat of primer for better adhesion. Continue applying even coats of primer until you reach the desired thickness and finish. Usually, this is around 3 – 4 coats.
