Does Epoxy Paint Need a Primer?

Whether you’re planning a huge home improvement project, or you’re simply sprucing up your floors, it’s extremely important that you take the time to apply a primer prior to using epoxy paint.

Let’s take a look at some of the main reasons why:

This is one of the most common reasons why you should always use a paint primer prior to applying an epoxy paint.

Besides being able to smooth the surface you are planning to paint by ridding it of cracks or imperfections, a high-quality primer will also ensure that the epoxy paint will be able to bond correctly to the surface.

Thanks to that, you’ll be able to have the peace of mind that your painted surface will have a reduced chance of peeling or coat chipping, while also enhancing its life.

The next reason why you should make sure that you use a paint primer before using epoxy paint is that a primer can help to prevent imperfections from arising on the surface whilst it is drying, such as bubbling.

Bubbling can be very common in epoxy paint (especially if you’re using many layers) because self-leveling can occur when the paint is settling, which can lead to air becoming trapped and bubbles rising to the surface.

A primer is specifically designed to aid the paint in properly adhering itself to the surface it is being painted on, while also reducing the chances of any bubbles, peeling, or cracking.

Thanks to this, you’ll be able to enjoy a much longer life of the finished paint job, and won’t need to worry about having to re-apply the paint for many years, although do keep in mind that external factors may speed up the degradation process, such as humidity and general wear and tear.

Nevertheless, the presence of a primer will be able to delay this process for a longer period of time than if you were to paint without one, not to mention ensuring a professional-quality finish free from imperfections.

What are the uses for epoxy paint?

Epoxy paint is well known for imparting a brilliant shine across all of the surfaces that it is applied to, which makes it a wonderful choice for covering areas of the home including patio floors, the bathroom, and even in the kitchen.

In addition to this, epoxy paint is also well known for its ability to resist scratches and exterior damage to its surface, as well as being able to withstand regular exposure to moisture.

Technically speaking, epoxy isn’t technically a paint because it consists of a chemical formula that blends together epoxy resin and hardener, something that neither water-based nor oil-based paints contain.

Due to this unique formula, it means that epoxy paint is able to achieve a durable, high shine, and chemical-resistant finish that is ideal for a wide variety of surfaces including kitchen countertops, marble floors, and bathroom walls.

It can even be used in saunas and pools due to its ability to resist damage caused by abrasion and water.

Can you paint over an epoxy primer without sanding?

Whether or not you will need to sand over your epoxy primer greatly depends on the type of epoxy primer that you have used.

More often than not, you will not usually need to sand over an epoxy primer, as the unique composition of epoxy paint usually means that it is able to bond itself correctly to the primer without any issues.

However, that’s not the case for all epoxy primers on the market, as some do require sanding prior to epoxy paint being applied on top of it, otherwise, the epoxy paint will be unable to adhere itself properly.

If you do need to sand your epoxy primer, you won’t need to use an electrical sander as this could cause you to sand the epoxy primer too far down and require you to have to re-apply a fresh coat of primer.

In contrast, we recommend that you use 320-grit sandpaper (the finer the better) and gently scuff up the surface of the dried epoxy primer in order to give it a little bit of texture.

This will then allow the epoxy paint that gets applied on top of the epoxy primer to be able to properly bond itself and dry correctly.

If you’re ever unsure about whether or not your particular epoxy primer can be painted on without any sanding, we strongly recommend that you refer to the manufacturer’s instructions that you’ll be able to find on either the back of the paint container or by reaching out to its customer service team who will be able to assist you.
