Epoxy floor coating benefits

Epoxy coatings provide your garage floor with exceptional durability and protection. This finish is impervious to damage from moisture, chemicals, abrasions, and UV light. Plus, the glossy surface is easier to clean than other types of flooring so you can keep it looking great for years!

Not only that, but epoxy coatings come in a variety of colors so you can customize the look of your garage. This product also gives off less fumes than traditional paints and sealers, making it safer to use in enclosed spaces.

There are a ton more benefits to epoxy coatings, but we’ve already written up an entire article about it, so let’s get into the upsides and downsides of doing it yourself.

DIY vs. professional application

So, we obviously wrote this guide to help you epoxy your garage floor yourself. But for some people, that may be a feat they’re not sure they are up to. Frankly, it’s hard to tell if it’s even worth the effort of doing it yourself. There are quite a few factors you need to keep in mind when deciding whether you should DIY or have a professional do it.


It should be quite obvious that doing it yourself is more cost-effective than having a professional installer come out and do it for you. You only need to buy the epoxy coating you’re going to use (we have suggestions here), as well as renting or buying the tools that’ll help you out.

A professional installer, on the other hand, will have you pay for both the materials and the labor. You won’t need to pay for the tools that they use, which is a plus, but the labor costs tend to outweigh the benefits if you have even a slight idea of what you’re doing.


If this is your first time epoxying a floor or anything in general, it’ll take substantially more time for you to do than for a professional to do it. You’ll need to go through basic steps like familiarizing yourself with the process, getting necessary materials, and potentially make mistakes multiple times before getting it done correctly.

Professionals, on the other hand, typically complete the project in 1-3 days, depending on their experience level. But, since they do it for a living, they will always be quicker than you can be.

Skill level

This is the biggest point of contention and the one that’ll likely convince you to either do it yourself or hire a pro. If you’re confident in your ability to epoxy a garage floor, then go ahead! But if not, then hiring an experienced professional installer would be much safer for both you and your wallet.

Final results

This may also be a huge factor to keep in mind – if you mess up when you epoxy your garage floor, that screwup will be there for a long time. If the result is unevenly applied, the adhesion could be weak or more susceptible to damage and lead to the epoxy wearing more quickly than it should.

Regardless, we still think doing it yourself makes the most sense – it’s a good learning experience, and why not?

Tips for epoxy floor coatings

Now that you know the pros and cons of DIY vs. professional application, let’s get into the actual steps for applying your epoxy floor coating.

What you’ll need

There are a few things you’ll need before getting started on your epoxy garage floor.

Equipment / tools

First and foremost, you’ll need the necessary tools and equipment to properly apply the epoxy coating. This includes a power washer or heavy duty mop, an electric sander or grinder, floor primer (if applicable), paint roller and tray (useful for making sure you get an even coat), mixing bucket, measuring cup, stir sticks, rubber gloves and mask. Additionally, if you plan on applying a decorative finish, you’ll need a decorative concrete sealer.


You will also need the necessary materials for the job. This includes your epoxy coating, floor cleaner, degreaser, acid etching solution (if applicable), and floor patch (also if applicable). If applying a decorative finish, you’ll need an acrylic or urethane sealer.

Now that you’ve acquired all of your materials and tools, the steps to epoxy your garage are quite simple.

Remove dust, dirt, and debris

The first step is to make sure that the surface you plan on coating is completely clean of all foreign particles. This includes removing any dirt, dust, and debris with a broom or vacuum cleaner.

Degrease the garage floor

If there is any grease or oil on the floor, you’ll need to use a degreaser before proceeding. Make sure to follow the instructions on the packaging and let it sit for at least 10 minutes before rinsing it off with a power washer or rag.

Apply primer (optional)

Once the surface is clean and dry, you may need to apply a floor primer. This will depend on the type of epoxy coating you plan to use, so be sure to check the manufacturer’s instructions before proceeding.

Etch the concrete (optional)

If you are applying an epoxy coating to a concrete surface, you will need to etch the floor using an acid-based solution. This process helps create a rough surface so that the epoxy can better adhere to it. Again, make sure to follow the instructions on the packaging and use all necessary safety gear when handling this type of chemical – it’s not necessary to do, but will ensure your epoxy lasts significantly longer if done properly.

Mix the epoxy coating

Now comes the fun part – it’s time to mix your epoxy. Make sure you’re following the manufacturer’s instructions for mixing and applying, as different types of coatings may require different methods.

Apply the epoxy coating

Once everything is mixed together, it’s time to apply your coating! Depending on the type of epoxy you are using, you may need to use a roller or brush to get an even coat. Again, make sure that all instructions are followed from the manufacturer and use all necessary safety gear when handling this material.

Add color chips (optional)

If desired, color chips can be added to the epoxy before it sets. This allows you to customize your garage floor and add a decorative finish. Be sure to follow the manufacturer’s instructions for adding these chips, as different types of coatings may require different processes.

Allow cure time

Once you have finished applying the epoxy, you will need to allow it to cure. This can take up to 72 hours, so make sure that you plan accordingly and don’t walk on or use the floor until it has completely cured. This will vary by brand, so make sure to read the manufacturer’s instructions to ensure you don’t mess up this part of the process.

Conclusion on epoxy for your garage floor

Epoxy is a great way to protect and enhance the look of your garage floor. With the right tools, materials, and process you can have a beautiful and durable garage floor in no time! Just remember to always follow the manufacturer’s instructions for mixing and applying the epoxy, as well as allowing adequate cure time before walking on or using your garage floor. Good luck and

happy epoxy-ing!
