Education: How To Choose the Best Oil Primer
Oil-based primer sealers come in various shapes and forms, sporting a variety of features. Here is what you may want to keep in mind.
What type of surface is this oil-based primer for? Can you use it only on wood, or is it compatible with multiple other surfaces?
Ideally, you should go for a high hiding formula with multi-surface compatibility. This way, you can work on metal surfaces, for example, after you are finished with the wood.
How many coats of primer do you need to apply? One or two coats of primer? The more coats you need to apply, the more time and product you will use.
Also, can you use any application method (i.e. a sprayer), or should you only use a brush? What kind of brush should you use? Consider these aspects before buying.
You may also want to consider the area of the application. If you want to paint only indoors, then an interior primer is sufficient. However, if you’re priming an outdoor project, opt for an exterior paint primer that will stand harsh weather conditions.
How much does one gallon of that particular product cover? In most cases, just 1 gallon of primer paint should cover 300 square feet of every surface.
However, make sure that you don’t need multiple coats in order to obtain that coverage. A thicker formula might give you more coverage in this case.
4. Drying Time
Each primer has a specific drying time. Unless it completely cures, you may not be able to follow up with the paint.
This is why you may want to consider the drying time of the primer. Some of them may take as little as 30 minutes, whereas others may take hours in order to fully cure.
No one likes strong-smelling primers or paint. These primers make it unbearable for you to apply on a larger surface without a mask. This is why you may want to look for something labeled as “low odor” instead. These are often less toxic and more environmentally friendly.
6. Stain Blocker
If you have watermarks or any visible imperfections on the surface, you might want to get an oil primer with stain blocking properties. Not only will it cover the stain, but it will also thoroughly seal the area so that future existing stains won’t show.
7. Rust Prevention
Is the area that you are planning to paint prone to developing rust? If you are priming metal, particularly on exterior surfaces, you might want to get a product that has a rust protection formula.
Why Use Oil Based Primer?
Some people might say oil based primers tend to be difficult to work with, as you need a lot of ventilation in the area. You will also require a mask that prevents you from breathing in the toxins.
Even with that in mind, an oil primer paint is guaranteed to do a great job. It is why professionals often opt for it in favor of latex based primers or the like.
As long as you prep the surface properly, the oil based primer paint should adhere correctly, sealing any pores and imperfections. It should provide good bonding so that you can follow up safely with the first coat of paint.
Is Oil Based Primer Better than Water Based Primer?
So, oil based or latex primer? Which one is better for your paint project? Well, it depends on various factors.
There are certain circumstances in which you might want to use an oil based primer rather than water based (i.e., latex primer). One thing that you should remember is that oil based paints and primers have a stronger smell and cause more fumes.
Without the proper equipment and good ventilation, this can cause irritation to the skin, nausea, or dizziness. If people are highly sensitive to these smells, then a better choice here would be a water based primer.
Oil based primers are not as fast drying as water based primers, but that is often because they have a thicker formula. If you use high-quality paint, then you may not even have to come back with a second coat of primer-sealer.
Oil based primers are also more efficient when it comes to sealing and covering stains. In comparison to water based primers, they penetrate wood much better, whether it’s new or weathered.
In the end, the choice mostly depends on what you need. Still, quality-wise, it is known that oil based paint and primer have a higher durability level.
Different Types of Primers
Depending on your paint project, there are various types of primers that you might want to go for:
1. Oil Based Primers
These primers are mainly used on wood, as they can enter and seal the porous areas. Other formulas are not usually recommended for these projects, which is why they are often referred to as the best primers for wood.
This is because they dry much faster and may provide a smooth working surface. Once you have the base, you may use oil or latex topcoat paint, whichever you prefer.
In terms of drying time, you can check out how long does it take primer to dry post.
3. Latex Primers
Latex primers are primers that are water-based, and they are perfect for using on interior surfaces like drywall. They dry fast and are perfect for projects that you want to finish fast. They are also low in volatile organic compounds (VOC), which means they have a low toxicity level.
4. Shellac Primers
Shellac primers double as bonding primers, and have great stain blocking properties. They can seal odors and can hide smoke or a water based stain. They can adhere to a variety of interior and exterior surfaces, including wood, metal or plastic.
Benefits of Using an Oil-Based Primer
Each primer type has its own benefits, but there are certain perks that come with using an oil based primer.
Oil paint primer are the perfect option for wood surfaces, as it won’t be so easily absorbed by the porous surface.
Here is what the oil paints will do for you:
- Fill into the small pores and imperfections so that you get a smooth, even finish.
- Coat wood surfaces so that you won’t have to use as much paint afterward.
- Prevents mold or mildew from growing on the wood surfaces.
- Helps paint dry faster
- Seals the exterior wood effortlessly and protects it against harsh weather.
Oil based primers act as a good base, and they are often more durable as compared to water based primers.
Tips for Applying Oil Based Primers
Applying oil based primer can make every surface look flawless, particularly if you apply it right. To make sure your paint job looks the best, here are some application tips that you might want to consider.
- Stir the primer before you use it. If it sat on the shelf for a long time, the oil might have separated from the rest of the formula. You need to mix them completely.
- Pour everything into another container. This way, not only will you further stir the formula, but you will also be able to keep the dirt out.
- If you feel like the primer is much too thick, don’t use water to thin it out. Instead, add some mineral spirits in the mix.
- Don’t use a low quality brush to apply the primer. Not only do you risk it shedding along the way, but it may also leave brush marks on the painted surfaces.
- Don’t paint over wet surfaces. Allow them to dry first. If you unsure,
A primer can prove very efficient, but you need to use it correctly. Make sure that you use the right protective gear. If it has high VOC levels, you might want to use a mask as you are painting.
What Kind of Primer Should I Use Over Oil Based Paint?
If you previously painted with a latex paint, you may easily follow with any kind of primer over it. For more info, check out the latex paint over oil primer guide. However, if your previous paint job was an oil based one, then you should only use an oil based primer sealer.
These primers have higher bonding properties, which means the chances of chipping or peeling as they cure are lower. The only instance when you may use a latex bonding primer is if you are self priming paints over a matte surface.
What is the Best Oil Based Primer for Wood
If you are looking for a good oil primer to finish a paint job, then by efficiency and popular opinion, the Zinsser Cover Stain is the best choice. Still, for those on a budget, the Rust Oleum Bulls-Eye 1-2-3 should also prove efficient.
Think about the surfaces that you will have to paint when you are looking for the best oil primer. Once you calculate all the factors, you should be able to choose the best option for your needs.
