Exterior Primer Paint Buyer’s Guide 

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 temperature 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.

  1. Drying Time

The drying time is the amount of time a primer requires too dry to 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. 

  1. 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.

  1. 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.

  1. 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’s a lot of products on our guide that cater 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.

Verdict

So, it’s clear that there are different kinds of primers available out there. Each kind caters to different types of surfaces and needs. Consequently, you will need to take the final call, depending on which of the functionalities offered by the product meets your specific painting requirements.

Before logging off, we wanted to quickly mention some of our top picks from the guide today. Rust-Oleum 286258, for starters, is the best glossy primer for external surfaces. KILZ ‎L220105, on the other hand, provides the most effective sealing and stain blocking solution that can make painting rough and porous surfaces rather easy.

Finally, we have the Rust-Oleum Zinsser 3134, which is the perfect primer for people living in humid locations. This not only effectively primes and seals your surface but also forms a crack, peel, mold, and mildew-resistant film that is guaranteed to last years. 

That’s all we have for you today! See you next time; until then, happy priming!
