Top 3 Myths About Paint Primer & How To Pick The Best One

The most important thing to remember about priming your walls is that there are a lot of options out there. You can pick from spray-on or roll-on, solvent-based or water-based, siloxanes or acrylics—the list goes on! So how do you know which one to choose? Well, here at HomeAdvisor we have done the research for you and put together this handy guide so that you can make an informed decision on what’s best for your project:

Myth #1: There’s Only One Kind Of Primer.

There are many different types of primers, and each one has a specific purpose. Paint contact primers are used to prepare a surface for painting, which makes them an important part of any painter’s tool kit.

Primers can be used on different materials, including wood and metal (for example, if you want to paint over galvanized steel). They can also be applied to different surfaces like drywall or concrete block walls in addition to bare wood or plaster work surfaces. Some primers even allow you to cover colours as well!

Myth #2: Primer Is Paint.

You may have heard the phrase “primer is paint.” It’s a common misconception that the two are interchangeable. In fact, they’re not even close. Paint contact primer [สี รองพื้น ปูน เก่า, which is the term in Thai] is a base coat and it has nothing to do with your actual paint job! The term “paint” refers to any form of pigment used on surfaces to give them colour or make them look better than they actually are—such as an oil-based paint or acrylics (for example).

Myth #3: You Can Save Time By Skipping The Primer.

One of the most common myths is that you can save time and money by skipping primer. While this is true in some instances, it’s not always the case. If you have a small area to paint or want to get some other work done on your house before painting, then this myth may work for you.

However, if your entire house needs to be painted and you want everything done as quickly as possible (and don’t mind paying more money), then I suggest using primer instead of just painting over whatever surface comes up first.

Paint won’t stick properly without primer—and even if it does go on perfectly smooth and evenly across your surface (which isn’t always guaranteed), chances are high that those pesky chipping marks will show up sooner rather than later anyway! Not only will this affect how long it takes for everything else around them like walls etc., but also their durability over time because if there are any cracks or chips within those areas due.


The best way to pick the right primer is by knowing what you’re looking for in a primer and what type of paint you’re using. If all else fails, ask your local paint store for advice! They can help you find the right product that will work with your project.
