Ever wondered how much does a gallon of paint weigh? If you’re like me and enjoy thinking about the weight of products, then this post is for you!

It’s impossible to figure out an exact weight because there’re different types of paint and also because paints vary in thickness.

To get a good idea of the overall weight of a gallon, we’ll need to calculate some averages, and I think you’re going to be surprised at how much your gallon of paint weighs. Let’s find out.

How Much Does a Gallon of Paint Weigh?

Calculating the weight of a gallon of paint depends on how thick or thin it is. Acrylic Latex Paint weighs between 6 and 12 pounds, oil enamel paint weighs around 15 pounds, egg tempera 2 pounds, and watercolor weighs around 4 pounds.

How Much Does One Gallon of Paint Weigh?

Paint is either sold in quarts or gallons. You need to know the exact quantity of paint in gallons you will need for your complete project.

If you’re buying a large quantity of paint or if you have a large painting job, such as a boat, this information can help.

The paint type and brand also have an impact on the weight. On average, a gallon-sized paint weighs 6 to 12 pounds.

In the medium size, you’ll most likely come across latex paints and enamel paints. Tempera paints are available in either half-gallon or gallon containers. On the other hand, acrylic and oil-based paints are often available in smaller quantities.

Latex and acrylic paint may be combined in a single paint on occasion. The difference between latex paints and vinyl is, they’re acrylic-based rather than vinyl.

Because vinyl is cheaper than acrylic paint, its hue may fail to adhere properly to surfaces. The best paint is gallon-sized latex/acrylic paints, which are considered high quality.

To choose the best paint type for your job, pay attention to the paint’s technical details to get an idea of its weight. When purchasing online, the weight is usually listed on the section with product information.

You can also inquire about the load-bearing capacity of your existing flooring. You might even ask for assistance calculating the weight at a local hardware store.

What Are the Standard Paint Measurements?

Before we get into the various paint options, let’s talk about common paint measurements. Gallons are the most common unit of measurement for paint. The most common sizes are one and five gallons, found in almost any hardware store.

A gallon is a measurement of volume, or the amount of space paint takes up. Because volume is unaffected by the paint’s density or weight, the gallon size remains the same regardless of the substance you’re measuring.

For instance, a gallon of water is the same as a gallon of paint or milk. The term gallon, however, is sometimes used to designate three different quantities worldwide. It might refer to:

  • U.S. gallon
  • U.S. dry gallon
  • Imperial gallon

In certain parts of the Caribbean and Canada, people use imperial gallon, about 4.5 liters, as the standard paint measurement. In the United States, a gallon is about 3.8 liters.

A dry gallon is a volume unit for measuring the weight of a liquid when it solidifies. It’s the amount of water in one pound per US quart, or 4.4 liters in an imperial gallon. The US dry gallon, on the other hand, is seldom used.

To measure volume, you must convert gallons to pounds. In addition, weights are regulated differently from country to country. In the United States, pound is used as the primary unit of measure for weight.

Actual Weight of Paint Gallons

The actual weight of a gallon depends on the type of paint you choose. A full-sized gallon can weigh as little as 6 pounds or as much as 12 pounds.

Latex paint is lighter than oil-based paint because it’s made from water, and acrylic resin is dispersed throughout the substance. In addition, oil-based paint is composed of varnish, which is denser than latex.

Refer to this list of common paint amounts available on the market:

  • 1 quart (2 pounds)
  • 1 gallon (8 pounds)
  • 2 gallons (16 pounds)
  • 5 gallons (40 pounds)
  • 10 gallons (64 pounds)
  • 20 gallons (96 pounds, used for railroad cars)
  • 40 gallons (192 pounds, used for bus models)
  • 60 gallons (288 pounds, used for big boats and planes)
  • 80 gallons (384 pounds, used by the army as a standard pack size of paint)

How Much Do Five Gallons of Paint Weigh?

Paint in a five-gallon paint bucket weighs more than a gallon, usually around 40 to 60 pounds. The weight will vary depending on the type of paint and the manufacturer.

A five-gallon container of latex paint, for example, weighs around 56 pounds. The bucket weight adds roughly 10 to 15 pounds to the overall load.

How to Convert From Gallons to Pounds

Because liquids have different densities, weights, and temperatures, converting them also varies.

To determine the weight of each gallon, you’d need to keep track of the gravity and the ratio of substrate density to water density.

On the portion of the physical characteristic of a paint’s safety data sheet, you’ll find an indication of the paint’s gravity. For pounds per gallon, multiply 8.35 by the number of gravity.

For latex paint and other liquids, you may use a pounds gallons converter.

Factors Affecting Weight of Paint 

The two main factors affecting weight of paint are pain type and paint base.

The paint’s composition is the reason for the difference in weight. Oil and water-based paints are the two most common types. In every paint, there’s a liquid and a pigment.

Some paints, on the other hand, include additions like rust or oil that give them color and aid in their priming capabilities.

The base is the liquid component in which all of the other components will dissolve. Thus, as the names imply, water-based paints include water, whereas oil-based paints include oil or solvent.

Usually, water-based paints are heavier than oil-based paints. It is also less hazardous because water dries faster and has few volatile organic compounds (VOCs). It can also be washed easily using water and soap.

Oil-based paint has natural linseed oil and synthetic solvent, and other harsh chemicals than water-based paint. Ensure you use it in an area with proper ventilation. Add either paint thinner or mineral spirits to improve its consistency.

Acrylic paint has an acrylic resin. It uses acrylic polymer emulsion, so it naturally contains more acrylic. Unfortunately, acrylic paints are rarely sold in gallon quantities unless they’re combined with latex paint.

Is Paint Heavier Than Water?

Paint weight is derived from non-water chemicals, although some are water-based. Paints can be lighter than water while maintaining a higher weight.

Paint is heavier than water; that’s why one gallon weighs 8.35 pounds or more. Assuming latex paint has 20% more density, it means a gallon is 10 pounds.

An oil-based transparent varnish, on the other hand, doesn’t contain paint pigments. The density of a gallon of water is 6.7 pounds, about 80% that of water.

When Does the Weight of Dry Paint Matter?

Dry paint weighs less. A gallon of dry latex paint, for example, weighs about four pounds, while a gallon of wet paint weighs around 11.3 pounds.

Paint loses much of its weight when it dries. The weight of the dry paint, on the other hand, may have a significant influence on the painting you’re working on. This will not have an effect when painting furniture.

If you’re working on a big job such as a boat, you need to understand dry paint weight. For this, you have to determine whether your enamel paint is oil-based or acrylic.

To find out the weight of your dried paint, check the safety data sheet of the paint distributor. The sheet has percentages of solids found in paint.

If the paint has 40% water, it means the remaining 60% are solids. The solids, or solid components, account for the paint’s weight once it has dried.

If you don’t use the entire gallon, it’s still possible to find the weight of your dry paint. Multiply the amount of paint you have used by the total solid weight.

Weight of Paint per Liter

Acrylic and oil-based paints are smaller in size, so you’ll want to consider the weight of your paint in liters. Acrylic paint is heavy, weighing about three pounds per liter.

However, because ounces are the most popular size, they are used as a standard measurement. The amount of weight varies somewhat by manufacturer and color.

FAQs 

How much does a 5lb bucket of paint weigh?

A 5 lb bucket of paint weighs around 50-60 pounds. A 1 lb bucket weighs around 11 pounds. The simple math brings us to our approximated figure of 50-60 pounds. The weight will vary depending on the type of paint and the quality of the container used.

How much does a full 5-gallon bucket weigh in pounds?

The weight of a full bucket will vary depending on the container, but it’d go up to 50 pounds depending on the substance filled. When filled with water, the five-gallon bucket will weigh 42 pounds. When filled with paint, the bucket will weigh 50-60 pounds.

How many pounds in 4 gallons of paint?

One gallon of enamel paint weighs around 11 pounds. 4 gallons would therefore weigh approximately 44 pounds. These are approximations because the buckets used may be different. Expect an error of either one or two because of this. The type of paint may also bring a slight difference.

How much does 1 gallon of water weigh?

A gallon of water weighs approximately 8.33 pounds, so if you have one gallon of water, it’s going to weigh around 8 pounds and 3 ounces. That’s around three kilograms. This, however, is subject to change depending on the temperature and pressure of water.

Does paint weigh less when dry?

Yes, the weight of paint when dry is usually lower than the wet measurement. That means when you’re checking out how much it weighs before buying, the measurements given are for dry paint. When the paint dries, the water that takes around 12% evaporates—the weight decreases as a result. So, on average, the final dry weight is around 2 pounds less than its wet counterpart.

How much does a 5-gallon bucket of Sherwin Williams paint weigh?

A 5-gallon bucket of Sherwin Williams paint weighs around 50 pounds. The weight of the bucket itself isn’t included in this figure, so you will have to add it depending on where you’re getting your measurements.
