A primer is designed to prepare a surface before the application of paint. This may be wood, metal, canvas, or a surface made from another type of material.
Have you been in the process of completing a painting project only to discover that the paint does not stick to certain parts of the surface, particularly those with an oily or greasy texture?
In some cases, the paint will stick well initially but it will begin to wear and peel sooner.
After dedicating your time to painting the surface or object, such results can of course be deflating as your efforts have not achieved the expected finish.
This is where a spray paint primer comes in. Simply applying one coat of the primer can make a huge difference to the finished appearance of the paint.
The product will act as an adhesive encouraging the paint to seal to the surface in which it has been applied. A primer can also help to minimize the appearance of blemishes.
If you are uncertain of the best spray paint primers on the market you have come to the correct place.

Buyer’s Guide
There are several factors that you will need to consider before choosing your spray paint primer, from when it should be used to the different varieties available. We have identified these factors below.
The Importance of Using A Primer
A paint primer plays an essential role in achieving high quality painting results. While it may be tempting to skip this step and compensate by adding several layers of paint you will experience several issues later on.
Initially applying multiple layers of paint instead of primer will appear pleasing but the paint will begin to chip or flake away.
Using a primer saves you the chore of having to repaint the surface a short time after, instead providing an adhesive layer that the paint can cling to smoothly from the get-go.
For long lasting, superior results, using a primer is super important.
Using a spray paint primer
You may likely be wondering when you should use a spray paint primer. Simply put, this product should be used every time you intend to paint a surface or object.
Using a paint primer will provide the paint with an adhesive surface to which it will stick to for the best results. Proceeding to paint without using a primer will result in uneven coverage.
Applying The Primer
Now you may be questioning when a primer should be applied. The surface that you are going to be painting on must be prepped before you attempt to apply a primer.
Of course, the steps involved in this process are going to differ depending on the type of surface or object that you are going to be painting.
Some primers will not require the surface to have been prepped or sanded down beforehand but others will. If you are going to be painting on wood, it will need to be sanded down and this is particularly important if the wood is still coated with an old layer of paint.
Sanding it down will get rid of any roughness to create a smoother surface that the new layer of paint can stick to.
If you are going to be painting a metal surface you can prime it using mineral spirits as this will remove any greasy patches. If necessary, the metal can also be sanded beforehand to ensure that the surface is smooth for uniform paint application.
Understanding Different Types Of Spray Paint Primers
As there are multiple types of spray paint primers available, it is important to choose the best option for your painting project.
Each type of primer possesses its own qualities that make it best suited to a specific type of surface. Due to the importance of a primer, selecting the best option is paramount in achieving high quality results.
Oil Based Primer
The first and perhaps most popular type is an oil-based primer. A primer of this kind is ideal for interior and exterior purposes and is particularly effective when used on a wooden surface.
By sealing the porous surface it will ensure that the paint sticks effectively. When used on cedar or redwood, an oil-based primer will stop the tannins that these types of woods release from bleeding through to the surface and affecting the overall appearance of the wood.
The versatility of an oil-based primer means that it can be used on a variety of different surfaces. However, there are a few issues to be aware of.
Oil-based primers are known to produce a rather strong smell and they can also be harmful to humans and animals due to the volatile organic compounds that they produce.
Because of this, it is important to ensure that you are kitted out in the necessary safety gear.
Water-based primer
The next type of primer is a waterproof primer, also known as a latex primer. Just like an oil-based primer, a primer of this kind offers excellent versatility when it comes to suitability with different surfaces.
As such, a water-based primer can be used on brick, metal, concrete, and softwoods. When used correctly, a water-based primer performs very well and boasts many advantages.
This includes quick drying properties and a low volatile organic compound content. Aside from this, water-based primers aren’t as brittle so they offer enhanced durability presenting less risk of chipping or peeling.
A great thing about water-based primers is that they are effective in creating a smooth surface for the paint to be applied to, this includes rougher surfaces too.
Just like oil-based primers, there are a few issues to be aware of when it comes to water-based paint primers.
Unfortunately, water-based primers aren’t as resistant to staining as oil-based primers which may provide concerns depending on the surface on which you intend to use it.
Tips For Choosing A Primer
Now that you are informed on the importance of applying a primer and the different varieties available, you may now be wondering exactly how you choose the appropriate primer for your needs.We have listed some tips to aid you in your decision below.
First, it is important to consider the type of surface that the product is going to be used on.
As you can see, both are versatile options when it comes to their compatibility with different surfaces, however, you may find that one offers a better finish.
Choosing the best primer for the surface that it is going to be used on will ensure that superior results are achieved.
Next, you will need to determine where the object that is going to be painted will be placed. If it is going to be placed in areas that are subject to high volumes of traffic it must be able to withstand this contact without deteriorating in quality.
Also, assess the state of the surface, there are of course differences between painted and unpainted surfaces so you will need to select the appropriate primer to coat the specific type.
It is important to consider the type of paint that you are going to be layering on top of the primer. Different types of primers will be better suited to certain types of paint so it is important to bear this in mind when making your selection.
Finally, consider the color of the surface or object that you intend to paint. Most primers are available in a range of colors which offers a broader selection to choose from and also increases the likeliness that you will find a close match to your paint.
Other brands will offer a more limited color selection which will make the task of finding the best color a little more challenging.
