Will Spray Paint Kill Grass?

Spray paint is commonly used to mark the ground during construction or simply as a type of decoration. Often this is done without considering the potential harm spray paint could do to your lawn. Only after the fact do most people think, “Will spray paint kill grass?” Further, not all spray paints have the same effect on a lawn. No matter what type of spray paint you have, you can learn whether or not it’s likely to kill your lawn below.

Will Spray Paint Kill Grass?

Spray paint will not kill grass if used in moderation. If you empty an entire can of standard-formula spray paint on a very small, specific area and make sure to coat all sides of each blade of grass, then you will kill that small patch of grass.

What Will Spray Paint Do to a Lawn

Will Spray Paint Ruin Grass Over Time?

So far you know that using spray paint as a marker, a little decoration, or as an accidental overspray shouldn’t harm your lawn. What happens if you intentionally spray paint your entire lawn? If you spend the money to have enough paint and equipment on hand, you can spray paint an entire lawn in just a few hours. It could be a healthy green or a ghoulish purple at the end of the treatment but will the grass survive?

How to Get Spray Paint Off of Grass

There are 3 decent ways to get spray paint off of your lawn before, during, and after it has dried.

• Mow Your Lawn – Often, spray paint will not cover more than an inch down on a blade of grass. Mowing this portion of the grass off will get rid of the appearance of the spray paint and leave no lasting residue. All paint-covered clippings should be bagged or swept up and discarded as they will not break down in the same way that typical grass clippings will.
• Use a Power or Pressure Washer – A pressure washed on a low setting can cause most types of spray paint to peel off of healthy grass.
• Scrub with Soap and Water – Using soap, not detergent or “dish soap”, a sponge, and some lukewarm water should allow you to easily scrub spray paint from grass.
• Acetone, Goof-Off, Paint Remover – The chemicals in all of these products will require further treatment after application and are often not a good choice to remove paint from your lawn. Further, acetone or paint remover applied in a sunny location will discolor grass if not immediately rinsed away while Goof-Off Graffiti Remover is not meant for use on plant life, according to its packaging.

Is Spray Painting Grass Illegal?

No, spray painting your lawn is not illegal. However, there may be certain covenants where you live, especially if you are part of an HOA, that may discourage or legally prevent you from changing the color of your lawn over a period of time.

Spray painting the grass in a public space or on property that is not yours could be considered vandalism or graffiti and is illegal, even if the spray is light or a temporary type of paint is used.
