5 Questions to Answer Before You Epoxy Your Garage Floor

How many times have you seen your car track in dirt, salt, and sand from the winter roads into your garage? And how easy is it to clean that mess up afterward? If you're like most people, the answer is probably "a lot" and "not very easy." The issue is that most garage floors are made of porous concrete, which allows grime and oil to sink into the surface.

But if you decide to epoxy your garage floor, you can create a protective barrier that resists everything your car throws at it — including engine oil, tire marks, and even chemical spills. This not only makes cleaning easier but also gives your garage a much cleaner and more professional look.

However, before jumping into an epoxy project, there are several important questions you should ask yourself. These decisions can significantly impact both the effort required and the final result. Let’s take a closer look at five key questions to consider before starting your project.

1. DIY or Hire a Pro?

Yes, you might have seen DIY epoxy kits on store shelves, and they seem simple enough. But don’t be fooled — applying epoxy to a garage floor isn’t always as straightforward as it looks. If your garage is large, or if the concrete has issues like cracks or uneven surfaces, hiring a professional might save you time, effort, and potential mistakes.

2. Epoxy or Polyurea?

Epoxy is a popular choice for garage floors because it’s durable and cost-effective. However, polyurea is gaining popularity due to its superior flexibility, faster curing time, and resistance to scratches. Keep in mind, though, that polyurea is generally three times more expensive than traditional epoxy. Consider your budget and long-term needs when making this decision.

3. How Porous is the Concrete?

If your garage floor is already smooth or sealed, you may need to grind it down to increase porosity. This step ensures that the epoxy adheres properly and lasts longer. Without proper preparation, the coating may not stick well and could peel off over time.

4. Are There Cracks in the Floor?

Cracks are common in older garages. If they’re too wide, they can compromise the integrity of the epoxy coating. In such cases, you’ll need to fill the cracks with a suitable sealant before applying the epoxy. This step helps prevent future damage and keeps the floor looking smooth and even.

5. What Will You Do With Everything in Your Garage?

Before you begin, you'll need to empty your garage completely. The process of preparing the floor, applying the epoxy, and allowing it to cure can take several days. That means you’ll need to find temporary storage for your belongings — either in your home or through a short-term rental. Planning ahead will make the entire process smoother and less stressful.

While these questions might seem daunting, taking the time to answer them thoroughly can help ensure a successful and long-lasting epoxy floor. Once you’ve got the answers, you’ll be one step closer to enjoying a clean, durable, and stylish garage floor.
