Buying the most expensive paints in the world won't do the trick if the primer you choose is not good enough. There are many things to keep in mind when purchasing the best paint primer. If you want a stunning paint job with an elegant finish, this buying guide will help you pick the best primers out there.
What Qualities to Keep in Mind While Choosing the Best Primer?
There are several primer variants present in the market, different from one another. To ensure that the primer you choose fits best with the surface, here are a few qualities to look for:
Primer Formulas
Currently, there are three primer formulas present in the market:
1. Interior and exterior primers are suitable for both indoor and outdoor paint jobs. They are hot in the market because of their multi-purpose properties. I/E primer is a popular choice among users who want different parts of their house primed and painted.
2. Exterior primers usually come with powerful anti-UV, fading, and weather-resistant properties. Since they are suitable for outdoor use only, this strong coating hardly cracks over the years.
3. Interior primers can only be used inside a building as they do not come with intense properties. It is best to choose milder primer with lesser toxins for indoor priming.
Filling Power
A high-quality undercoat primer can also smoothen the inconsistencies in the surface that is about to be primed. However, you need to make sure that the walls are adequately plastered. Otherwise, the effect can be pretty prominent.
Opacifying Abilities
The primer's opacifying ability is a property that allows you to conceal the base color of the surface. A primer with higher opacifying abilities will definitely result in a more uniform and even-colored coat. A low-quality primer, on the other hand, requires dilution that may result in lower opacifying power. Be careful when choosing one.
Coverage Per Surface Area
Before starting a perfect primer job, it is crucial to estimate how much paint you might need. A liter of standard paint can cover around 6.5 square meters. However, high-quality primers can get a better result and more area covered, and less paint is used. Other than a smooth application, they require significantly lesser retouches allowing you to save some extra bucks.
Tint Capability
Although most primers are available in white and gray, you can purchase a primer that can be tinted to a different shade. A primer with the label ‘Tintable’ can help you achieve a more consistent and plush final result.
Drying Time
The drying time depends on the type of primer you choose. For instance, an oil-based primer will need a couple of hours to dry. A latex primer only needs 45 to 60 minutes to dry out.
What Types of Primers are Available in the Market?
Different primer types showcase a unique base ingredient that completely changes their property and usage.
Acrylic Primers
Acrylic primers are a relatively modern touch to vinyl primers. They are a popular choice for both indoor and outdoor use. Here are some properties of acrylic primers:
- Water-based primers (latex)
- High-performance primer
- Non-flammable
- Used for undercoat and finishing
- Available in matt, gloss, and satin variants
- Quick-dry with no pungent smell
- Easy application
Vinyl Primers
Known for their coating properties, vinyl primers are usually used as an undercoat or to apply a finishing touch. Following are the properties of vinyl primers:
- Water-based primers (latex)
- Low pigmentation
- Quick dry
- Odorless
- Low-performance primers
Glycerophtalic Acid Primers
Glycerophtalic acid primers are strong and must be used only on specific surfaces. Here are the key characteristics of glycerophtalic acid primers:
- Require turpentine solvent that leads to a strong chemical smell
- Oil-based primer
- Easily applied over any kind of paint or surface
- High opacifying power
- Consistent finish
- Take longer to dry
- Cleaning brushes after priming is hard
Which Primer is Best for Each Surface?
You cannot just take any primer you like and apply it on a random surface. For best results, you need to pick a primer suitable for the area you want to paint.
- An oil-based primer is perfect for unpainted and painted wood as it will smooth the surface while leaving a denser color coat
- A latex primer is suitable for drywall as it ensures a smoother and even finishes
- A latex stain-blocking primer is suitable for surfaces that are prone to solvent stains like grease
- Use an oil-based stain-blocking primer for non-solvent stains such as smoke
- A rust-resistant oil-based primer can help the paint stay on for longer while avoiding corrosion
- Glossy surfaces can be even- coated using a latex primer such as acrylic
What Tools are Required When Using a Primer?
It might seem like a hefty task at first. However, with proper tools, you can easily DIY something as challenging as a paint primer. Once you have decided on the best paint primer, some essential tools are required to complete the process.
Safety Equipment
Primers can be poisonous and toxic if they come in contact with your face or skin. You must wear appropriate gear to ensure maximum safety. Safety goggles, masks, gloves, and paint overalls are highly recommended for powerful primers.
Rollers and Brushes
Rollers and brushes can change the outcome of a priming surface altogether. You can choose between:
- Synthetic, bristle, or foam brushes of 1 to 5 inches width depending on the surface area.
- Microfiber, wool, synthetic, or foam rollers between 4 to 9 inches width depending on the surface area you will apply the primer on.
Ladders
A step ladder may come in handy if you plan to apply primer on higher surfaces such as walls and gates.
Final Thoughts
Primers are a mandatory requirement in some paint jobs as they ensure a smooth and flawless finish. There are different variants of primers available in the market. All are suitable for a particular type of surface.
Before buying the best paint primer, you must look at the properties and qualities. Once clear, you can gather all the tools and start working on the walls, making them completely new.
Just make sure that you have a rough estimate of how much primer is required for the entire process. This will not only help you budget properly but also reduce any kind of wastage. Usually, high-quality primers provide better coverage while saving your costs by one good investment.
