Factors to Consider Before Choosing a paint for Lawn Mower Deck

When you are in the market for unique paint for your lawn mower deck, there are things to consider which will help you make the right choice. Here are a few of them:

Mower deck type


One of the key factors to consider before buying your next lawn mower deck paint is to know your mower deck type. Knowing your mower deck can help you decide on the paint that will be a good fit for it.

If you get the wrong choice for it, it might not do a satisfactory job, worse, it could damage your mower deck’s surface. 

Check the chemical(s) of the product

You have to confirm if the chemicals of the spray paint are not toxic and hazardous. Make sure that it is also safe for inhalation. 

Some chemicals can be terribly harmful to the extent that they can cause permanent eye damage, irritation or further injuries that occur as a result of contact with the product. 

Tips to Paint a Mower Deck


There are important steps in preparing a mower deck for painting. These steps include: 

  • Apply primer if necessary

Although some spray paints do not require a primer. Check the label to confirm if it requires you to prime the metal surface. You may also go for a two-in-one solution (paint and primer).

  • Give it some time

Give it some time after applying the primer (if necessary). This will allow the product to sit on the surface. You need to allow it to dry so that you won’t ruin the whole process.

  • Take your paint brush or spray can

If the mower deck is ready for painting, you can take out your paint brush or spray can and begin to paint the surface. Put several newspapers or clothes on the floor to avoid stains. Apply paint on the deck in an even manner. You can go over the painting process if another thin paint coat is needed.

  • Divide the painting process into two coats

It is important to undercoat the mower deck so that it can provide a strong footing to the final colour. In addition, it gives a fine boundary between the primer and the outer coat.

  • Give it a top coat

You can give it a top coat when the inner coat is completely dry. A cheap paint topcoat is okay for rarely used mowers while an “eggshell” type of paints are used for roughly used mowers to give it a new look.

How to Keep Grass from Sticking to Mower Deck

When grass clippings accumulate in your mower’s deck, it might make it less efficient. This build-up results in corrosion. Here are some tips to prevent grass from sticking to the mower deck:

  • Clean the deck

You can clean your deck with a pressure washer and a piece of cloth. Water aids in the removal of the accumulated clippings. However, the use of a garden hose coupled with soft bristle and soapy water will remove these clippings with ease.

  • Keep the surface dry

Exposure to water vapor and damp environments can cause corrosion. It is recommended that you keep the surface of your mower dry. Ensure that you empty the tanks before you start your preventive maintenance.

  • Tilting the mower

When there are rusts on the decks and blades, the mechanism is always slow, thus, producing less desirable results. Tilt the mower to check the rusted parts and clean grass clippings from them.

  • Spray with paint

Use the tip of your spray paint container to dry the underneath of your mower’s deck. Allow them to dry and treat all the rusty surfaces with primer before applying the coat. You can apply the coat with bush-on spray paint, spray lubricant or mask rust. After covering the affected parts, allow the coat to soak the surface and make sure that it is properly dried. This will save the deck from rusting.

  • Check the mower’s air filter

Always check the mower’s air filter for any grass clippings or debris. This will make you clean the mower deck easily.

The Importance of Applying Spray or Brush-On Paints for Lawn Mower Decks

Although there are some long grass clippings on decks and undersides of the mowers, wet grasses get stuck more than dried grasses. This affects the level of efficiency of the mower deck. It causes unnecessary delays in cleaning and removing grasses from the mower deck. 

The application of non-stick paints is one of the effective ways to keep your mower deck from rusting. They reduce the accumulation of grasses and debris on mower decks. These paints prevent clogging and make it easy for you to clean.

In addition, it helps you to maintain a consistent surface irrespective of any weather condition. This will enhance the durability of the mower deck and make it less prone to rust. 

One of the differences between spray and lubricants is that lubricants can be sticky while spray or brush on pants doesn’t promote grass build-up. Spray or brush on paints enables the surfaces to be hardened.
