Why choose an oil based primer when using a paint sprayer?
The goal isn’t to use a product that will spray well, although that is important.
The best oil based primers help to create a tighter seal on an item that is going to be painted.
It is the ideal primer paint for wood projects, drywall, and plaster because the primer fills in the porous surface of each.
Instead of a rough surface, you’re left with something smooth that is waiting for your paint. With the best paint sprayer in your arsenal, you can prime and paint quickly and easily.
Several brands offer oil based primers that are suitable for the modern paint sprayer. It is important to ensure the viscosity of the primer will work with your paint sprayer before purchase.
You should never thin primer just to use it with a paint sprayer.

Before you get started with any painting project, a couple layers of primer are generally necessary. Primer allows the paint to apply with better consistency, offering a smoother and flatter surface for a better end result.
For a long-term project, an oil-based primer is a better option. Oil-based primers take more time to dry and require thinning to apply through a spray gun.
The results tend to last much longer compared to other primer types.
Some paint types are incompatible with some primer types. Be sure to follow the recommendations of the manufacturer when using any primer or paint.
Any unfinished surface can benefit from the use of an oil based primer if it is going to be painted in the near future. Porous materials should always be primed before painting.
That means concrete, wood, drywall, and even certain metals need primer.
It can be tempting to skip this step when painting. The results, however, never seem to be as good without primer when compared to having it done.
That means an oil based primer should be used whenever painting needed to be done. There are only a handful of exceptions to this rule.
Oil based primers dry very slowly. In return, they provide a finish that is smooth and protective.
These primers can even benefit woods that tend to have their tannins bleed through over time.
If you’re working with cedar, for example, an oil based primer will help to maintain the integrity of your paint.
You should also use primer paint on painted surfaces that are beginning to fail. It will help to cover any cracking or chalking to offer a lovely visual aesthetic.
Oil primer paint is one of the most powerful tools that are available to painters today. They are also one of the most overlooked tools. It seems like skipping the primer paint is an easy way to save time and money.
It is not. Primer helps the paint stick properly to the surface being worked. It allows for a consistent coat that becomes smooth as it dries.
Primer does more than help the paint. It can also solve the visual aesthetic issues that plague certain walls and wooden surfaces.
A good oil based primer will cover up stains and prevent an old stain from leaking through to the paint.
A good oil based primer will also conceal odors, such as cigarette smoke, that can penetrate the drywall.
Oil based primers can be extremely smelly when being applied. Even a well-ventilated room may not prevent these odors from lingering for a couple of days.
These primers require a thinner for cleaning as well. For consistency, however, there isn’t a better option when dealing with tough pre-existing stains or odors.
It is a good idea to match up your primer with your paint. In some instances, you may not know if the paint is latex or an oil-based variety.
You can check your paint type by saturating a shop rag with non-acetone nail polish remover.
Take the soaked rag and run it over the painted surface in question. If no paint comes off on the rag, then you know for certain that it is an oil-based paint.
If the surface is coated with latex paint, then you’ll have some paint come off on the rag or the surface will feel sticky afterward.
Whether or not a primer can be thinned so it can be applied with a paint sprayer depends on the manufacturer.
If you look at the application instructions on the product, you will find a thinning ratio to follow, assuming it is permitted.
The general rule of thumb for thinning primer paint is to remove about 1.5 cups of primer from a 1-gallon can and then add 1.5 cups of thinning agent to the product.
If the label of the primer does not specify a thinning ratio, then it must be assumed that the primer should be used as it is. Run the undiluted primer through your sprayer to evaluate its thickness.
In most cases, it will spray as a thin mist and you’ll be fine.
If it sprays thickly, then you may need to apply the primer manually.
Attempting to thin a primer that is not intended to be thinned can change how it applies, how it dries, or how it supports a layer of paint in the future.
If you are trying to thin an oil based primer or paint, you cannot use water to do so. Water and oil do not mix. You’ll need to use mineral spirits to get the job done. Follow our instructions on how to thin oil based paint.
With oil primer, always double check and follow the manufacturers instructions on how to thin the paint.
The cost primer paint is comparable to the cost of the paint that you’re planning to use for your project. Expect to pay at least $30 for a 1-gallon container of the best paint primer.
If you have a smaller project in mind, you can purchase primer containers that are pint-sized or below in the $10-$25 range. These small containers are not enough to apply primer to an entire room, though it could be large enough for something like an accent wall.
You may be able to save some cash if purchasing your primer in bulk.
A 5-gallon container is usually about $120. You can also step up to a high-quality product for about $170.
