Can you use epoxy resin on concrete?

If you’re reading this article, then the chances are that you already know what concrete is and why it’s so popular. But do you know what epoxy resin is? Did you know that epoxy resin can be used to coat surfaces of different materials, such as wood or metal, and give them special properties? One of these properties is the ability to make a surface waterproof. If you are looking for a way to take advantage of all the benefits of concrete while giving it waterproofing properties at the same time, then there’s good news: yes, you can use epoxy resin on concrete.

But why would someone want to use epoxy resin on concrete in the first place? And how exactly can it be done? To answer these questions, we will first need to understand what makes epoxy resin so unique.

Can you use epoxy resin on concrete?

Installing epoxy on a concrete floor is a tricky business. If you don’t follow the steps correctly and in order, your hard work will most likely end up with a bubbled, uneven mess that needs to be stripped off. However if you do it right, the floor will have a gorgeous glossy finish that’s tough as nails and easy to keep clean.

First steps

Before applying any sort of epoxy coating, you need to make sure the surface is completely dry and dust-free. Any moisture or dust particles can interfere with the bond between the epoxy and concrete. We recommend using an industrial vacuum cleaner with a HEPA filter to get rid of all traces of dust before starting any work (remember that your vacuum cleaner should also be equipped with a HEPA filter).

Can you pour resin over concrete?

The short answer is no, you cannot pour resin over concrete without priming it first. To get the best results with your epoxy project, you should apply a primer to the concrete before pouring in your resin. Concrete that is not properly primed will prevent the epoxy from curing and may result in the product yellowing or losing its transparency.

You can prepare your concrete by using a chemical etching agent to prime it. This solution will eat into the surface of the concrete and make it easier for any coating, such as epoxy, to properly adhere to it. The etching agent must be neutralized afterwards or else it can continue eating into your surface!

Can you epoxy outdoor concrete?

Yes, you can apply the epoxy resin on outdoor concrete. However, you need to take some precautions:

  • Try to avoid direct sunlight or UV rays.
  • Avoid rain or high humidity.
  • Use a concrete sealer to prevent moisture from penetrating your concrete slab.
  • Use a moisture barrier in combination with a dehumidifier to keep your epoxy application dry while curing.

You should only apply the epoxy during the day when the temperature is above 50°F (10°C).

How do you apply epoxy to concrete floor?

To apply epoxy to concrete, first you’ll need to prepare your floor by cleaning it as thoroughly as possible. You’ll also need to repair any holes or cracks in your concrete. Then, apply a concrete etching solution with a brush and allow it to soak for about 15 minutes. Once the etching solution has soaked, rinse it off with water.

Next, you’ll need to apply a primer to the floor in accordance with the instructions provided by the manufacturer of your specific brand of epoxy. Then, roll on the epoxy using a paint roller in accordance with the instructions provided by your manufacturer. When applying both the primer and epoxy be sure not to leave any puddles behind as they can result in unattractive patches where they dry separately from the rest of your floor.

Finally, wait until your epoxy has fully dried before walking on it or moving anything over it.

Will epoxy stick to smooth concrete?

Epoxy resin is great for a number of different uses, including sealing concrete floors. However, it will not bond to smooth concrete.

If you have a smooth concrete floor, you’ll have to etch it with acid first in order for the epoxy resin to adhere properly. This is easy enough to do even if you’re inexperienced with this type of task. A simple solution of muriatic acid and water (following the instructions on the packaging) will do the trick.

Can I apply epoxy resin on my driveway?

Yes, you can apply epoxy resin not only to a garage floor but to your driveway as well. In fact, if you have concrete driveways that look worn out and damaged, using epoxy resin is an excellent option for covering up the cracks and making the floors look more beautiful.

The thing about applying epoxy over concrete floors is that it is not easy to do. This means that if you want to use epoxy over your driveway, it’s better to hire someone who knows how to do it properly so as not to mess things up and waste money in the process. For this reason, many homeowners opt not to do it themselves but have a professional handle their floors instead.

Can you epoxy over rough concrete?

Yes, you can apply epoxy to rough concrete. In fact, you don’t even need to do anything to the surface of your concrete before covering it with epoxy, as long as it’s clean and dry. You may want to fill in any cracks or holes in the concrete first, though. If you’re doing this job yourself, then you can rent an epoxy injection kit from a hardware store and fill the cracks with it; if the holes are too big for this (or if there isn’t one available at your local hardware store), then you can use foam crack filler instead.

If you have a large area of rough or uneven concrete that needs to be covered with epoxy flooring, then you should know that there are several different ways that you can do so:

• The most common way is to pour your epoxy onto the floor and let it sit overnight so that it will cure at room temperature; however, this method has some downsides—it takes longer than other methods because of how slow curing happens without heat. You’ll need two people helping each other out if using this technique due to its size (and some heavy lifting). Finally, since drying times vary depending on humidity levels outside/inside where application takes place – wait times might be anywhere from 12-24 hours!

How long does epoxy last on concrete?

The durability of epoxy on concrete is a hotly debated topic that lacks conclusive scientific data, so you’ll have to make an educated guess about how long it will last. Some say that the lifespan of your epoxy coating depends on its quality and the protective layer it offers. In this case, high-quality epoxy can last between 30 to 40 years. On the contrary, low-quality ones can last for less than 10 years.

You should also consider the environmental conditions where you plan to apply your epoxy coating. For instance, if there’s constant movement and exposure to moisture, your epoxy coating will not last long. The same goes for surfaces exposed to constant vibrations or heat and cold fluctuations that exceed 40 degrees F every day (that’s 5 degrees C). Otherwise, you can expect your epoxy flooring to perform well for up to 20 years or more with proper care and maintenance.

On average most garage floor coatings have a lifespan between 4 and 12 years depending on foot traffic and other factors like sunlight exposure etc..


In this article, you learned what epoxy resin is and how to determine whether your concrete surface is strong enough to apply it. You also learned that there are several ways to fix any issues with strength before applying the epoxy resin. In addition, you discovered a few tips for those who wish to use epoxy resin outdoors. Finally, we discussed some of the benefits of using epoxy resin on concrete surfaces both indoors and outdoors.

If you take care to prepare your concrete surface properly, then you will be well on your way to making it shine with an attractive new coat of epoxy resin.
