Frequently Asked Questions (FAQ)

Should I use epoxy primer?

Epoxy primer is a great way to ensure a smooth finish and often an important step in the painting process. You need an epoxy primer if you want to achieve a smooth, glossy finish. It also improves adhesion and durability. This is especially useful if you want to protect your painting from heavy use and the elements.

Epoxy primer is usually applied as a very thin layer. Before you paint over your primer, let it dry completely. Once it’s cured, you can apply a finish coat as normal.

If you’re painting over a darker surface, it’s worth choosing a high-quality epoxy primer. The best ones won’t change the pigmentation of your original color.

Does epoxy primer stop rust?

Technically speaking, epoxy primer will not stop rust on bare metal, but it will eliminate rust on painted surfaces. The chemical reaction that takes place between the primer and the rust will stop the corrosion process.

How much epoxy primer do I need?

The amount of epoxy primer you’ll need will vary based on the size of the project or products you’re upgrading. When you’re determining your quantities, you’ll want to consider an additional 20 percent for extra.

If you’re looking to upgrade your kitchen cabinets, you’ll probably need considerably more. If you’re just upgrading your doors, you’ll likely need to spread it a little thinner.

There are three factors that affect how much epoxy primer you’ll need:

Project size if you’re using this for a large job, like your kitchen cabinets, you’ll need to use much more than if you’re just doing a small project.

What is epoxy primer?

When it comes to home improvement projects, most people choose to either oil-based or latex primers to ensure a smooth and clean finish. However, the epoxy primer is more popular than these two, which are also less expensive. This is because it is more durable than both of these primers while offering a smoother and better surface to achieve perfect results with your next paint job.

Epoxy primer is a water-based acrylic material with a noxious odor. This is why it is usually sold in spray cans to help you ventilate the room while applying it. Not only does this primer offer you a smooth and beautiful surface, but it can also last for a long time. It can actually be up to six times stronger than other materials, which is why it is commonly used wherever it’s exposed to heavy traffic. Think of it as a product that will work well for your outdoor patio area, walkways, outdoor furniture, and more.
