The amount of epoxy you need depends on the surface you want to use. If you want to create an epoxy countertype, wall, or floor you need around 10 mil thickness. To determine the exact epoxy you will need to multiply the floor length by the width and depth of the pour. After this, you will then convert the result to liters. Below we will discuss the needed epoxy for the different surfaces you might want to use it for.

Epoxy Flooring System Coverage Rate Amount of Epoxy Needed (for 1 coat)
Self-Leveling Epoxy 50-100 sq. ft. per gallon 1.5-3 gallons per 100 sq. ft.
Epoxy Mortar 25-50 sq. ft. per gallon 4-8 gallons per 100 sq. ft.
Quartz-Filled Epoxy 50-60 sq. ft. per gallon 2-3 gallons per 100 sq. ft.
Metallic Epoxy 50-60 sq. ft. per gallon 2-3 gallons per 100 sq. ft.
Chip Epoxy Flooring 30-40 sq. ft. per gallon 2.5-3.5 gallons per 100 sq. ft.
Solid Color Epoxy 50-60 sq. ft. per gallon 2-3 gallons per 100 sq. ft.
Epoxy Terrazzo 50-60 sq. ft. per gallon 2-3 gallons per 100 sq. ft.

It’s important to note that the actual amount of epoxy needed may vary depending on several factors, such as the condition of the substrate, the thickness of the coating, and the desired aesthetic result.

Factors Affecting Epoxy Flooring Coverage

  1. Substrate condition: The condition of the substrate, such as its cleanliness, smoothness, and porosity, can affect the amount of epoxy needed to cover it.
  2. Epoxy thickness: The thickness of the epoxy coating can also affect the amount of material needed to cover the substrate.
  3. The desired aesthetic result: The desired aesthetic result, such as the color, texture, and pattern, can affect the amount of epoxy needed.
  4. Room dimensions: The size of the room or space where the epoxy flooring will be installed will affect the amount of material needed.

Calculating the Amount of Epoxy Flooring Needed

  1. Measure the length and width of the room or space where the epoxy flooring will be installed using a tape measure.
  2. Multiply the length by the width to get the total square footage of the area to be covered. For instance, if the length of the room is 20 feet, and the width is 10 feet, the total square footage will be 200 sq. ft.
  3. Determine the coverage rate of the epoxy flooring system you’ll be using. The coverage rate is the number of square feet that can be covered by one gallon of epoxy.
  4. Divide the total square footage of the area to be covered by the coverage rate of the epoxy flooring system. For example, if the coverage rate of the epoxy system is 50 sq. ft. per gallon, divide 200 sq. ft. by 50 sq. ft. to get the total number of gallons needed. In this case, you’ll need 4 gallons of epoxy flooring for one coat.

How much epoxy is required for a countertop?

To determine the epoxy needed for a countertop, you will measure the square footage of the countertop. If you don’t know how to do that, you can read some online tutorials that will give you the right measurements.

Don’t also forget to take into account if you need a skim coat. Depending on the material of the countertop, which can be wood or concrete, you should seal the surface with a coat of epoxy. If you have a countertop epoxy, a full gallon of epoxy should be enough.

However, if you want a thick epoxy marble countertop, you should get two gallons of epoxy, metallic powders, charcoal, and the base color.

How much epoxy is needed for an epoxy wall?

To know how much epoxy per square foot is needed for a wall, you should measure all square footings of your countertop. A Quart of epoxy will cover about 70 square feet of your wall. If you want a thick epoxy wall, you could get one and a half gallons of epoxy, pearl, and base color. For an 82 ft wall, it is recommended you get about three gallons of epoxy. If you want your wall to have amazing 3D effects, you should apply an extra coat of epoxy over the wall.

How much epoxy do I need for a river table?

The exact estimate you need for your river table depends on the volume of the river. To get an accurate idea to measure the length, width, and depth of the river table. Once this is completed, multiply your answers together. A good example is when you have a river table of 10.75 inches by 10.75 inches and about 2 inches deep. For this river table, you will need a gallon of epoxy.

How much epoxy do I need for a floor?

To have an idea of how much you need for a floor, you will need to get the right measurements. For an average floor surface, a full gloom of 100% epoxy coating should be enough for a 1600 sq ft. The thickness of the epoxy will also determine how much it will cover the floor. A good estimate is :

  • An epoxy gallon at 1-millimeter thickness will cover a 1600 sq ft floor
  • A gallon of epoxy at 5 millimeters thickness will cover 320 sq ft of floor
  • A Gallon of epoxy at 10 milliliters will cover 160 sq ft floor

The above numbers are based on an ideal floor setting in most homes. Also, floor epoxy coverage depends on the substrates. Also for harsh floor surfaces like concrete and wood, you will need to skim-coat the surface. A quart of skim coat will cover about 72 square feet.

Conclusion

Having an epoxy floor is highly recommended for most public buildings. We have discussed the amount of epoxy you will need based on different surfaces. These epoxy are resistant to many chemicals, cope well with harsh weather conditions, and are highly decorative. Also, they are easy to clean, maintain and cope appropriately with underfloor heating.
