How Much Does One Can Of Spray Paint Cover?

Are you wondering how much coverage you can expect from one can of spray paint? The amount of coverage that a can of spray paint provides can vary depending on a number of factors, such as the surface being painted, the type of spray paint, and the technique used.

In general, one can of spray paint covers around 25-35 square feet, but this can vary depending on the factors mentioned above. In this article, we will explore the factors that affect the coverage of spray paint and provide tips on how to get the most out of your can of spray paint.

Whenever people purchase spray paint, they usually ask for the number of cans to complete their projects. It is sometimes difficult to assess how many cans are needed as spray paint is highly variable and depends on how you apply it. It also depends on the amount of overspray you generate.

Number of Spray paint cans; overall square footage of surface

Keep in mind that the number of spray paint cans is usually dependent on the overall square footage of the surface you have to cover. On the other hand, the number of spray paint cans also depends on the amount of paint in each spray can and the number of coats you need to apply. 

Amount of Spray paint per can

Typically, the amount of spray paint can be very easy to estimate. Spray paint manufacturers quickly state the estimated square footage of deciding whether spray paint can work in the market.

The number of coats needed

The number of coats required should also be considered. These coats have to be painted on a particular surface, such as a wall or furniture, as we all know that we get the best results when applying multiple thin coats.

So whenever you want to purchase spray paint cans, keep in mind that you must need at least two coats. Two coats are enough for dark color paints, but if you are going for lighter colors such as yellow or orange, you must plan for an additional 1 to 2 coats. So we conclude that if we use bright colors, we usually need 5 to 6 coats. 

Overall square footage area

Along with the number of coats, the number of spray paint cans also depends on the overall square footage of the surface area. So you must figure out the overall square footage of the area by using some geometry.

You can do this easily by figuring out your square footage and breaking your surface into different rectangles. We all know that the rectangle area is determined by a length in weight; it is usually measured in feet.

Then we have to multiply the length by the width, and it is your square feet. After that, you have to add up all the rectangles, and then you will get your overall square feet area.

Then you have to divide that square feet area by 20 square feet, and then we can quickly evaluate the number of spray cans needed to spray the particular area.

Measuring the area in inches

To calculate the area in inches, we must multiply the length by the width to get the total square inches. After getting the results, we have to divide it by 144 and convert it into the total square feet. 

You must know that some surfaces have more surface area than the length by width indicates. Also, consider whether the surface you are painting has openings or not because while painting the openings, you will end up with overspray.

To determine the number of spray paint cans, you will need, multiply the number of coats by the number of cans you determine.

If you have custom spray paint, adding a margin factor-like 30%, is good to account for waste. Ensure you order enough spray paint for your entire project to prevent batch variations. Normally, the number of spray paint cans is usually dependent on the surface you are covering.
