how thick should epoxy be on garage floor?

Epoxy is a great way to make your garage floor look more professional and last longer. It’s also great for preventing oil and gas leaks from being absorbed into the concrete.

However, it can be difficult to know how much epoxy you should use when applying it to a new or existing concrete floor.

There are some things that you need to consider before deciding exactly how thick your garage floor should be coated with epoxy.

How thick can epoxy be poured garage floor?

The thickness of epoxy is important because it determines how flat and smoothes your floor will be. The thicker the layer, the less likely that you’ll see bumps or dips on your final product.

It’s recommended that you use a 3/8″ trowel when applying the epoxy. This allows for enough room for all of the material to flow between trowels without leaving too much behind in one area and risking uneven results.

You also want to use good-quality epoxy so that it won’t mix with air bubbles when poured onto your garage floor (and cause cracking).

How many coats of epoxy do you put on a garage floor?

The number of coats of epoxy you will need to apply depends on the type of floor you are coating and the color you select.

The standard garage floor application is 3 coats, but this can vary because some applications may require more or less depending on the condition of your garage floor.

When choosing a color it is important to consider how many coats are needed because different colors require different amounts of material applied.

For example, if a white epoxy is being used you will only need 2 coats when using an 18 ounce kit, but if a darker color was used like black then 3 full kits would be required at least.

How much thickness does epoxy add?

Epoxy is a thick liquid that is poured on the garage floor. It’s made of two parts: one part hardener, and one part resin.

The hardener and resin combine to make a thick liquid, which is poured into molds that form the concrete surface of your garage floor.

When it’s dry, epoxy becomes hard and durable enough to protect against most wear and tear. That’s why epoxy coatings are often used for floors exposed to cars in garages, parking lots and other areas where vehicles spend time driving over them regularly (like driveways).

Can you put a second coat of epoxy on garage floor?

Yes, you can apply a second coat of epoxy on your garage floor. For example, if you want to increase the thickness of your epoxy by about three quarters of an inch, then yes; you can put a second coat on top of the first one.

While this may not be necessary for most people and most garage floors, it may be worth doing if:

  • You want to make sure there are no bubbles in your first layer (this would be harder to do after applying two layers)
  • You want a thicker coating on your floor

How thick should a garage floor be?

How thick should a garage floor be? That depends on what you plan to use it for. If you’re only storing some stuff, then you don’t need the same thickness as if you are working on your car.

The reason for this is that a thicker epoxy will have more cushion and be less likely to slip and fall when someone trips over an object in their way or when they’re putting something down on the floor.

This can also prevent accidents with kids playing around inside of your storage space, where they might otherwise get hurt by falling objects hitting them in the head or back if there was no protection from impact damage while walking around inside of your garage area at home.

How thick does a resin floor need to be?

The thickness of your epoxy flooring will vary depending on what you want the finished product to look like. The thicker your epoxy, the harder it will be and the more expensive it will be. Here’s a quick breakdown of what each thickness will produce:

1/4″ Thick – This is often called “half-inch” because it’s half as thick as a normal 1/2″ product. You can use this if you have already laid down some sort of vinyl or carpeting overtop of your concrete slab.

It doesn’t show any seams when installed correctly and doesn’t require any special tools beyond standard hand tools (a drill) or power tools if you prefer that route instead.

Do I need to Prime garage floor before epoxy?

You need to prime the garage floor before you apply the epoxy. Before you can do that, however, you’ll need to clean and sand your concrete.

If there are cracks or holes in your concrete (and there probably are), then use a sandable primer to fill them up. This will make it easier for the epoxy to stick when you put it down later on.

Note: Some people skip this step because they think it will save them time and money, but if done correctly it could actually help save both!

Should epoxy garage floor be smooth?

Epoxy is not a smooth finish. In fact, it’s the opposite of smooth. Epoxy is a porous surface that will have texture to it and even small bumps in the flooring material.

The purpose of this is to prevent spills from soaking into the epoxy and causing an unsightly mess when they dry out over time.

The texture also makes sure that there are no glistening spots on your garage floor—a common complaint among people who have poured too much liquid epoxy into their garage floors.

So if you’re looking for a perfectly smooth finish all throughout your garage, then you need to look elsewhere (like maybe concrete).

But if you’re okay with leaving some imperfections in your garage floor because they come with benefits like increased traction, then read on!


The thickness of epoxy on a garage floor depends on your application. If you are using it as a sealer, then a thin film is sufficient.

If you want to lay down epoxy as a smooth and flat surface for paint or other coatings, then 2 inches would be the minimum recommended depth of epoxy required to achieve that level of smoothness.
