While glossy paints provide a lot of aesthetic benefits, they also tend to highlight the imperfections of the surface it’s applied on. Hence, it’s necessary to properly prep a surface you plan to apply this on. Apart from that, the manufacturer recommends keeping the paint overnight before recoating. Sometimes this drying time extends even further depending on the weather. 

4. Rust-Oleum Zinsser 3134

Rust-Oleum, as we mentioned before, is an extremely well-established brand in the paint and home improvement industry. The Zinser 3134 from its range is specifically formulated for households exposed to high humidity and therefore prone to mold and mildew concerns.

Buying Guide For The Best Exterior Primer Paint

With that, we’ve come to the end of our top 7 reviews. But are you still confused about which of these products is the best option for you? To help you answer this question, we have compiled a comprehensive buyer’s guide for you. In this guide, we have listed some of the key factors to consider while purchasing primer paint for your exterior projects. 

So, what are we waiting for? Let’s jump right into it!

1. Environment

The environment you will be working in or the climate that you live in is a very crucial factor to consider while buying primer. The environment determines the temperature of your location and some primers out there have a very specific range of temperatures in which they can be applied. 

Furthermore, the environment contributes to issues such as mold and mildew formation. So, if you’re living in a high-humidity area that is prone to these issues, you might want to buy a paint primer that is mold and mildew resistant.

2. Drying Time

The drying time is the amount of time a primer requires to dry to the touch. Alternatively, cure time is the duration it takes for primers to dry completely after which you can either recoat or apply the topcoat of your project. These are significant when it comes to determining the overall project duration time. 

3. Coverage Provided

This factor includes two very important aspects of primers you need to consider. First of all, how much area one tin of this product can cover and secondly, how many coats you require to cover it. Both of these together determine how much paint you will require to cover a certain surface area. Hence, they also simultaneously help you understand how affordable a primer really is.

4. Finish Of The Primer

Different products offer an assortment of different finishes to your project, ranging from flat, glossy, satin, and so on. Each finish has its own advantages and disadvantages. So, for example, a glossy finish is really easy to maintain but they tend to highlight the imperfections of the surface. 

Alternatively, a flat finish primer offers more coverage and sealing properties but is difficult to maintain in the long run. Hence you need to decide on the finish depending on your surface type and preparation.

5. Versatility

This includes both versatility in paint application surfaces as well as paint application methods. Although this article is specifically for exterior primer paints, there are a lot of products in our guide that caters to a wider variety of surfaces. Similarly, most of our primers support varied application methods and allow you to choose what you’re most comfortable with.

Exterior Primer Paints FAQs

Can I use interior primer for the exterior surfaces of my house?

It’s not recommended because exterior primers are formulated to withstand weather conditions like rain, hail, snow, and sunlight, unlike interior primers.

Is it important to clean the surface before applying exterior primer paint?

Yes, for the primer to adhere properly, the surface should be clean, dry, and free of loose or peeling paint, mildew stains, dirt, and rust.

What's the best way to apply exterior primer paint?

Exterior primer paint can be applied by rolling, brushing, or spraying. Each method has its pros and cons, so choose the one which suits your project and skill level best.

How many coats of primer do I need to apply?

Most of the time, one coat of primer should be sufficient. However, if the surface is highly porous, stained, or if there will be a dramatic color change, additional coats may be necessary.

Conclusion

Understanding the perk of a good-quality exterior primer paint is important if you're looking to wholly revamp the look of your house or even a particular exterior structure. An ideal exterior primer not only serves as a protective layer for your exteriors but also enhances the aesthetic value by providing a smoothened base for the final topcoat. Primers, in general, prevent stains, rust, and peeling, and they also enhance the durability of the topcoat paint.

From the above seven best exterior primer paints, here are the top three expert recommendations:

The Rust-Oleum Zinsser 286258 Bulls Eye primer is an ideal option for those looking for a deceptively simple and versatile primer. This high-performing primer is noted for its smooth coverage, compatibility with a broad range of surfaces, and its water-based formulation that makes it easy to apply and reapply within a short duration. It's ideal for surfaces that have been previously painted, including masonry, wood, metal, and drywall. In spite of some complaints about poor shipping procedures, the overall performance of this primer is commendable.

The KILZ ‎10111, an oil and water-based primer, is a good option for those who desire a blend of premium performance and durability. This primer offers excellent coverage and a highly resistant finish, and it supports various application methods including using a roller, brush, or spray gun. If prepped properly, it adheres and covers brilliantly on surfaces like plywood, fences, and laminates. Despite its long drying time, its enduring finish is worth the wait.

Lastly, for someone who is looking to get the double benefits of a primer and a topcoat, the Prestige ‎E500-9 is the right choice. This two-in-one paint and primer has an easy-to-apply formula with excellent coverage and a high-end finish. It's mildew-resistant, which makes it perfect for high-humidity areas. But for best results, you need to give the surface a good preparation, given its semi-gloss finish tends to highlight imperfections.

While shopping for the right primer, some might compromise on certain factors, but as long as you're aware of what you require in your primer, you'll make the right decision. Each primer mentioned above excels in its quality, versatility, and protection, while also offering aesthetic benefits to your exterior surfaces. Explore each of these options and choose what suits you best.

Remember, a good painting job starts with a good primer. So invest wisely!
