How many gallons of paint do I need for a 2 car garage floor?

Congratulations on deciding to paint your garage floor! You probably have some questions like: “What is the size of my garage?”, “What type of paint am I using?”, or “Am I going to oil my garage floor or use a water-based paint?”. These are all important questions and the answers will help you determine how much paint you will need for your project.

In this article, we’ll discuss some important information about painting and how to prepare your garage floor for painting.

How much paint do I need to paint my garage floor?

Luckily for you, Polycuramine is pretty easy to measure out.

One gallon will cover 400 square feet and the kit we used came with two gallons.

To determine how much paint you need for your garage floor, first determine the square footage of your garage.

It should be fairly simple to do if your garage is just concrete and not already painted since that’s all it needs to be measured in feet.

If you have a two car garage then it will most likely be around 350-400 sq. ft and that means one gallon of paint will cover 80% of what you need with some extra space left over, but if your garage is a little bigger or smaller then use this formula: Number of feet wide x Number of feet long / 400 = Gallons Needed

Because we were planning on painting both our walls and our ceiling white, we had to account for that too.

We wanted our colors to all match so we made sure to buy the same brand of paint so everything would look cohesive together even though we were using different types of paint for each application (drywall vs concrete).

We ended up using 3 gallons total before tax was added in at $27 per gallon which totaled $81 plus tax which was way cheaper than what we had been quoted by a professional painter ($800) who specifically paints garages only in the area!

What kind of paint should I use on my garage floor?

  • Concrete paint
  • Masonry paint
  • Epoxy paint
  • Latex paint
  • Polyurethane paint
  • Acrylic paint

How many square feet does a gallon of garage floor paint cover?

Garage floor paints are typically sold in one gallon cans. These paints often have a thick consistency (check out this link for more information about the different types of garage floor paint and how to pick the right one for your project).

This thick consistency is designed to ensure that there is a higher build on the surface itself so you don’t need two coats. It also means that you can expect around 350-400 square feet of coverage per gallon.

So how many square feet do you need? Well let’s take a look at an average 2 car garage as a reference example. A 2 car garage will typically measure 20′ x 20′, or 400 square feet. Garage floor paint covers about 400 square feet of surface area per gallon, so most projects will require only 1 gallon!

How many square feet is a 2 car garage floor?

To find out how many square feet is a 2 car garage floor, you do some simple math: multiply your garage’s length by its width. A typical 2 car garage is 20 x 20 feet, so this comes out to 400 square feet.

If you’re painting the walls or the ceiling too, remember that those measurements are different. The wall space of a 2 car garage typically measures 40 x 20 feet (800 square feet), while the ceiling space usually measures just 20 x 20 feet (400 square feet).

How much paint do I need for 600 square feet?

Now that you know the basic formula for calculating how much paint you need, let’s go over some common scenarios.

If your garage floor is 600 square feet, you’ll need one gallon of paint. If it’s 1,200 square feet, two gallons; if it’s 1,800 square feet, three gallons; and so on. A good rule of thumb to remember is this: One gallon covers about 300 square feet.

How much does it cost to paint a two-car garage?

The cost of painting a two-car garage depends on the size of the garage, the cost of paint, and how much of it is required. If you are painting both the walls and floors in your two-car garage, it may cost more than if you were just painting the floor.

However, because two cars usually park in a two-car garage and car tires leave marks on painted surfaces, it’s best to paint both the walls and floors.

What type of paint is best for garage walls?

The paint you choose for your walls should be durable and easy to clean. You also want the paint to resist mildew, mold, and stains. Latex or acrylic paints are fine for garage walls. Oil-based paint is a good choice if you want something that is stain resistant.

You may also want to choose glossy paint for your garage walls since it’s easier to clean as well. Another option is enamel or epoxy-based wall paints because they’re easy to apply and can handle the wear and tear of being in a garage.


In summary, the amount of paint you need for a 2 car garage floor depends on several factors: 1) how big the area is, 2) how many coats you’re applying, 3) whether or not you’ll be using primer, and 4) whether or not your project involves two-car garage walls as well.

If you’re looking to paint only your garage floor, we recommend a minimum of one gallon per coat—but if you’re painting walls too, then we’d suggest getting enough to cover all surfaces (including the ceiling).
