Does epoxy make concrete waterproof?

In this article, we’re going to answer the question: Does epoxy make concrete waterproof?

We’ll begin by describing what epoxy is and how it works. From there, we’ll talk about its effectiveness as a sealer and when you should use epoxy. We’ll also discuss different application methods for epoxy and how you can figure out which one will work best for your project.

Finally, we’ll share some helpful tips for using epoxy, so you can get the best results from your project every time.

Is epoxy good for waterproofing?

Is epoxy good for waterproofing?


Yes, it does. Epoxy is a resin that is mixed with a hardening agent. In contact with water, the resin and hardener react to form a strong, waterproof bond. This means epoxy is often used for waterproofing surfaces, waterproofing concrete, waterproofing roofs, waterproofing basements and waterproofing pipes.

Is epoxy floor waterproof?

Is epoxy floor waterproof

Many people wonder if epoxy is waterproof. When we talk about waterproofing a surface, we often only mean that the substance lives up to its name; it’s a surface that repels water in some way. Epoxy resin is generally non-porous and water-resistant, but it isn’t inherently waterproof. Through proper application, though, you can make epoxy floors waterproof and mold resistant. However, if you expect your floor to be exposed to sunlight or UV rays frequently (ex: an outdoor patio), you’ll need additional protection for the floor.

Epoxy surfaces are easy to clean, durable and protect against water damage—however, they’re not immune to wear as time goes by. If you plan on using epoxy on your basement floor or patio surface, make sure your ground has been appropriately leveled prior to installation so that any cracks or crevices don’t compromise the smoothness of the surface after it cures completely.

As with anything important in life, there are drawbacks too: epoxy floors are susceptible to slipping because of their smooth texture and slick nature when wet (so be careful where you install it). Additionally, epoxy floors should not be exposed regularly to UV rays as these will break down the compound over time (served best for indoor or covered outdoor applications).

Can epoxy be used on concrete?

Epoxy is a versatile material that can be applied on concrete. The term epoxy refers to a two-part adhesive, coating and filler material. The common denominator for all epoxy materials is that they contain at least one epoxide group per molecule, which makes them chemically reactive. Epoxies are known for their strong adhesion and durability, which makes them popular in industrial and commercial applications.

How long until epoxy is waterproof?

To answer the question, no, epoxy is not waterproof. But it’s not meant to be.

Epoxy is a material that works as a barrier between moisture and concrete. It’s commonly used in basements or other areas where water issues are present or expected. When applied properly according to manufacturer specifications, it will let the concrete breathe while preventing moisture from passing through to the flooring system above. The amount of time it takes for an epoxy coating to cure can vary by brand and product, but it’s generally between 24-72 hours.

What makes epoxy waterproof?

What makes epoxy waterproof

Here is what makes epoxy waterproof:

  • It is dense. Water can’t penetrate the surface of a concrete surface coated in epoxy. Instead, water just sits on the surface and eventually evaporates.
  • It is durable. Epoxy coating resists wear and tear, stains and scratches that could allow water to seep through it.
  • It is flexible. If there are tiny hairline fractures in your concrete floor or wall, the flexibility of an epoxy coating will prevent those cracks from spreading deeper into the concrete or letting water pass through them.
  • It is resistant to abrasion, chemicals and UV rays. Of course all these things can damage your concrete surfaces, but if your surfaces are coated in epoxy they will be protected from any erosion that could expose them to water damage (or just general disrepair).

Epoxy flooring is one of the most durable flooring options on the market. It is also one of the most desirable and comes in many different styles, finishes, and colors. Epoxy floors can last for as long as 20 years with proper maintenance. This makes it a good option for both indoor and outdoor flooring needs.

When it comes to waterproof epoxy floors, they are very strong and durable. They are resistant to water, chemicals, and dirt. They also offer a non-slip surface that helps prevent slips and falls in wet or slippery conditions. In addition to being waterproof, epoxy floors are easy to clean up after spills or messes because they don’t allow liquids or debris to penetrate into their surfaces

How long does an epoxy floor last?

How long an epoxy floor lasts depends on several factors, including the quality of the epoxy, the type of epoxy used and how well your floor was prepared before application. If your floor was not properly cleaned before installation, the new finish will not adhere properly. If it has not been properly maintained after installation, it could start peeling up prematurely. We’ve seen floors last anywhere from 15 years to a few months; it all depends on what you put into it!

Is garage epoxy waterproof?

Is garage epoxy waterproof?

The short answer is yes and no.

The long answer is: the concrete needs to be clean, dry, and in good condition before applying any epoxy coating. If all of this is true, then the chances are that you will have a waterproof floor.

If the concrete isn’t properly prepared before applying epoxy, it may lead to bubbling or peeling of your epoxy coating.

But if you take the time to prepare your concrete correctly, you can be sure that your garage floor will look amazing for years to come and won’t be absorbing water anymore!


Epoxy flooring can be waterproof, but not on its own. In order for an epoxy coating to make a concrete surface waterproof, the epoxy layer needs to be thick enough so that no moisture can penetrate it. Properly sealing the concrete beforehand is also essential in preventing cracks or holes from developing in the concrete. While epoxy flooring is durable and long-lasting, it is not indestructible and will degrade when exposed to harsh chemicals or abrasives.

While this may seem like a lot of information, following these steps will ensure that your DIY project gives you years of reliable service. Whether you’re looking at applying an epoxy membrane inside your home or protecting your patio outdoors, this guide will take you through all of the steps necessary to ensure that your next project goes off without a hitch.
