What Ruins Composite Decking?

In this article, we will detail the various types of factors that lead to damage to composite decks. Understanding these can help you extend the life of your deck.

6 Common Practices That Ruin Composite Decking

Typically, the main cause of ruined composite decking is incorrect practices by homeowners. For example, cleaning incorrectly can damage the surface of the deck. Here are some common missteps.

Placing Metal Items on The Deck

Metal furniture placed on a composite deck for a long period of time can create a serious rust problem. When metal surfaces are continuously exposed to moisture, it accelerates the oxidation process. The rust it produces may penetrate inside the composite deck material. This will cause the deck to be stained with rust stains that are difficult to remove and affect the aesthetics. Therefore, it is recommended that you give preference to aluminum or stainless steel outdoor furniture.

These materials offer better resistance to rust. You can also add rubber or plastic protective pads to the bottom of your metal furniture. In addition, check the condition of the surface coating of metal items regularly and refill the paint in time. Metal items should be moved to a dry place for storage during rainy or wet seasons. These tips will prevent metal items from damaging the deck.

If rust has developed on the surface of the composite deck, you can use a special cleaner with a soft brush to gently scrub it. If the rust has penetrated deep into the material, you may need to consider partial replacement of the deck boards.

Failure to Timely Clean up Leaves, Grass Clippings, and Other Debris

Leaves, grass clippings, and other organic materials decompose in a humid environment to produce tannic acid and other coloring substances. At the same time, they also provide an ideal growth environment for molds and fungi. Acidic substances secreted by microorganisms during metabolism can also corrode the deck surface.

Therefore, it is recommended that you clean the deck surface regularly. Especially during the leaf season, increase the frequency of cleaning. In addition, check the deck seams regularly to prevent the accumulation of debris. For mold spots that have formed, you can use professional cleaners to treat them.

Wrong High-Pressure Cleaning Method

Some homeowners like to use high-pressure water guns to clean their decks. However, we would like to remind you that improper use of a high-pressure water gun can cause damage to a composite deck. For example, too much water pressure can cause the surface material to peel off. It can even cause gouge marks if sprayed too close.

In addition, a high-pressure water gun may damage the sealing of the deck joints. For this reason, we recommend that you use a garden hose with a soft-bristled brush to clean your composite deck. Even if you use high-pressure cleaning, you should pay attention to the following points:

  • Choose a fan nozzle.
  • Control the pressure at 1500-2000 PSI.
  • Keep a distance of at least 20cm from the deck.
  • Ensure adequate drying after cleaning, especially at the joints.

Using a Metal Shovel to Clear Snow

In winter, snow may often accumulate on composite decks. Snow penetration and snow removal operations also pose a risk of damage. Many metal tools can scratch the protective surface layer. Therefore, it is important to remove ice in winter to prevent long-term water buildup.

Use a plastic snow shovel when removing snow. When removing snow, keep it oriented parallel to the deck boards. This will avoid damaging the surface texture of the deck. In addition, avoid using corrosive snowmelt salt.

Use of Corrosive Cleaning Agents

The choice of cleaning agent is also important for composite decks. Chlorine bleaches can damage composite deck surfaces. They may degrade and discolor the deck surface. In addition, corrosive cleaners may damage the metal fasteners of the deck. In severe cases, they can even damage the deck structure.

Therefore, read the instructions provided by the deck manufacturer before using the cleaner. Choose a pH-neutral composite deck cleaner or mild soapy water. Rinse well after cleaning to avoid cleaning agent residue.

Placing Potted Plants on Composite Decks for Long Periods of Time

Sometimes, you may place some plants on your deck to decorate your outdoor space. But this can lead to some problems. Prolonged wetness at the bottom of the pots can lead to moisture retention. This can cause localized mold. Damage may also result from the bottom of the planter rubbing against the deck surface.

The solution is to use an outdoor planter with a water reservoir. You can also place water barrier trays underneath regular planters. It is important to move the position of the planter regularly to avoid fixing it in one place for a long time. In addition, choosing planters made of lightweight materials can also reduce scratches.

How can I Extend The Life of My Composite Deck?

In addition to avoiding the above practices, you can also adopt some methods to extend the service life of composite decks.

Regular Inspection

Although composite decks do not require frequent maintenance and care, regular inspections are necessary. You can check whether the deck fixings are loose once a month. At the same time, pay attention to whether the deck is deformed or sunken. In addition, the deck’s drainage system and bottom ventilation should also be checked frequently. Timely maintenance when problems are found can prevent serious damage.

Use High-quality Composite decking

The quality of composite decking determines its durability. Choose composite decks from good manufacturers such as EVODEK and Trex. They have better quality and warranty. You don’t have to worry about damage caused by daily use.

Conclusion

Proper usage and maintenance practices are key to ensuring that your composite deck is beautiful and durable for a long time. Avoid these practices that ruin composite decking if you want to keep your outdoor space looking its best.
