Composite decking is known for its high-quality durability and low maintenance. It is also very resistant to mold, so many people choose composite decking material as their building material. Although it has good resistance to mold, like other materials, it can become moldy in extremely humid environments. But don’t worry, composite decking board has a protective layer on the surface, so mold will not cause serious damage to the interior of the deck. However, mold can affect the aesthetics of the outdoor space and can even make the surface of the deck more slippery, posing a health risk. So it’s important to take steps to keep mold away from your outdoor deck. In the next article, we will discuss how to keep mold off the composite deck and bring you ways to clean it.
Like wood and wood decking, composite decking material contains wood fibers and can develop mold. Mold is a fungus, a plant without leaves and stems, and in a suitable climate, this natural spore grows very easily.
Warm, moist air and water pooling on composite decks are conditions in which they can survive very easily. Mold on composite decks is not common, but that doesn’t mean it doesn’t happen. In the right conditions, mold can grow on the surface of the deck and leave very unsightly spots. But don’t worry, mold on composite decking is very easy to clean up.
Keeping your outdoor deck regularly clean is one of the most effective ways to prevent mold growth. You need to regularly sweep the deck surface of debris such as leaves, dirt, and oil stains. which can easily trap water and create a suitable environment for mold growth. In addition, you need to use a hose to regularly clean the deck of stains and dirt. For some stubborn stains, you can use a plastic deck brush and warm soapy water to clean them. It is important to note that you must not use metal brushes or sharp objects to clean, as this can cause wear and tear on the deck surface. When rinsing the deck, be sure to rinse off the soapy water thoroughly, as the residue may also lock in moisture and cause mold growth.
Another of the most effective ways to address mold is to make sure that the water on the deck surface drains in a timely manner. This means that you need to install composite deck boards with the right slope to ensure that the moisture on the surface drains away in a timely manner. This is an effective and simple way to ensure that water does not easily remain on the surface of the deck. If you find that the composite decking board surface still retains water. Then you need to re-adjust the slope of the deck surface or install an additional drainage system. For example, install drainage tiles or a drainage system that can easily drain water from the deck.
Mold can only survive in a moist, warm environment. So maintaining good air circulation between the deck and the framing can be effective in preventing mold growth. Keeping air flowing means you can’t place plants, potted plants, or dense furniture on the deck surface. These items will interfere with air circulation. Alternatively, you can install a ventilation system around the composite decks, which is a very effective way to keep the air flowing. You need to leave space for the ventilation system on the side when installing composite decking boards.
If you install composite decks in a very wet, rain-prone area and notice that mold has started to form on the surface of the deck. Then you may need to use a mold inhibitor to prevent the growth of mold. Be sure to note that the mold inhibitor should not contain any chemicals that could cause serious damage to the composite deck material. When using a mold inhibitor, read the manufacturer’s instructions carefully. Different mold inhibitors will vary in how they are used and how long they take effect.
Choosing composite deck materials that are naturally mold resistant. It can be effective in preventing mold from forming on your deck, some composite decking is specifically designed to resist mold growth. Which is a better option for some homeowners who live in a humid environment. It allows you to stop wasting time with mold on the deck surface and be able to better enjoy living in your outdoor space.
When it comes to the best way to remove mold on composite deck surfaces, it looks a lot different than the traditional way of cleaning a deck.
When preparing to remove mold, consult with your supplier first about deck cleaning considerations. Make sure that the cleaning method you use will not cause harm or damage to the composite decking. Generally speaking, composite decking is very easy to clean, using detergent, warm soapy water, and a soft deck brush to remove the mold easily.
We do not recommend using a pressure washer to clean. If you have a mold problem on composite decks, pressure washing may cause the mold problem to worsen. Because composite deck has a softer texture than natural wood, using a pressure washer may cause damage to the deck.
If you need to use a pressure washer. Be sure to use a lower pressure value to reduce the possibility of damaging the deck. And make sure the washer is at least 6 inches away from the balcony.
