Buyers Guide For The Best Lawn Mower Deck Spray

While the information mentioned above can help you choose the best lawn mower deck spray, you must know what to look for in a deck spray before buying it. Mentioned below is a complete buyer’s guide for buying a lawn mower deck spray, so read on below to make an informed decision.

Corrosion And Rust Prevention

When buying the best lawn mower deck spray, the most important feature you need to consider is checking if it offers corrosion and rust prevention. This feature is essential, especially if your grass is moist when using your mower. Moisture can harm your equipment, and riding mower decks can easily get corroded or rusted in a short time. Wet grass causes premature corrosion, and with a rust and corrosion prevention spray, you can deal with this issue easily.

Corrosion And Rust Prevention

Easy Application

Another thing to keep an eye on when buying a lawn mower deck spray is easy application. Now, most sprays come with a fragrance-type nozzle and are easy to use; however, there are some that do not allow easy application. Some do not have a ready-made formula that can increase the use time and make it a chore to apply on your mower.

Furthermore, your product must be quick to dry because you do not want to wait for days or even hours for the deck to dry before you use it. Instead, opting for a spray with a short drying time and easy application will allow you to look forward to using it.

Non-Stick Formula

The worst thing that can happen to your lawn mower deck is to get it sticky. Stickiness can make a mess since grass clippings can get stuck on it, and it will take more time to clean it. To avoid grass or debris sticking on the mower, you must opt for a non-sticking formulation for lawn deck spray. This way, your deck will be free from debris and remain safe and clean for us.

Smooth Finish

Apart from making sure you get a non-stick formula, you must also lookout for a smooth and clean finish. Nobody wants a mower with a weird texture or leaves behind a color. A clear finish will give your mower an attractive look and won’t make the spray stand out. In fact, your mower will look exactly like it usually does but get the benefits of rust and corrosion prevention.

Smooth Finish

Long-Lasting And Waterproof Nature

When you buy a spray for the deck to deal with rust and corrosion, you want it to be long-lasting regardless of the product’s price. Longevity ensures that you do not have to reapply the product and its waterproof nature allows you to leave the mower outdoors even during monsoon season. Furthermore, rust can occur over a few weeks, and so long-lasting nature can prevent this easily even if you forget to apply it after some time.


While you may be buying a spray only for your lawn mower, it won’t hurt to get a multi-purpose product. This way, you can use it on other tools and machinery. Some sprays can be used on electrical components, which makes it a great investment, and since they keep rust and corrosion away, you can use them on other machinery if you want.

How To Apply A Lawn Mower Deck Spray

Now that you know what to look for in the best lawn mower deck spray, you must also know how to apply it. The application for this product is fairly simple, and with the steps mentioned below, you can easily follow it and do it on your own, so keep on reading.

How To Apply A Lawn Mower Deck Spray

Wipe The Deck

You need to thoroughly wipe the deck to eliminate any debris, dirt, or clipping present on the surface. This step will allow the liquid sealant to cling to the surface properly. However, allow it to completely dry before moving to the next step.

Apply The Spray

When the deck is all dry, you can now start with applying the product. A spray will allow you to get an even coat, and all you need to do is keep the spray a few inches away and cover the entire deck with it. However, do not go back and forth with the product but try to apply a single layer only.

Apply The Spray

Wait For It To Dry

Once the product is applied, wait for it to completely dry. Depending on the product you get, drying time can be anything from a few days to even a couple of hours.

Apply It Again

Once the entire surface is dried down, you can move forward with the second coat. The first coat is enough for the industrial-grade spray but for your peace of mind, applying a second coat is a good idea. Two coats offer you greater protection and keep your deck better.

Allow It To Dry Down

When the second coat is applied, you must again allow it to dry completely. Usually, a second coat can take more time, but the deck is protected and can be freely used once it dries down.


How can I clean a lawn mower deck?

The easiest way to clean a deck is by wiping it with a wet rag and some soapy water. You can also use a high-pressure garden hose and wash down the deck to avoid water entering the machinery. The pressure from the water will remove the toughest dirt and grime and allow easy application of the spray.

How long does a spray last?

The spray longevity depends entirely on the manufacturing company. Some sprays can last for months, whereas some last for a few weeks. Also, quality plays a huge role in it and so choosing a high-quality spray is a smart idea and doesn’t require frequent reapplications.

Are there signs that show when you need to reply to the spray?

There are obvious signs that will allow you to know when the deck needs a reapplication. These signs will be that the grass clippings will start getting stuck on the deck, and the mower will not spin smoothly. Also, if the deck is getting corroded or rusty, then it is time to reapply the spray.
