What Causes Mold And Algae On Decking?
Mold and algae often form on surfaces that are exposed to excess moisture and humidity for long periods of time. The presence of these organisms can lead to a slippery surface and discoloration of the decking material, leaving your deck looking aged and unappealing.
Here are some of the most common factors that contribute to the growth of mold and algae on decking-
- Lack of sunlight: Mold and algae thrive in damp, shady areas with little to no sunlight. If your deck is located in a shaded area, it may be more prone to the growth of these organisms. Likewise, if you always cover your patio with a tarp or other material, it may not get enough sunlight to keep the mold and algae away.
- Exposure to excessive moisture: Moisture from rain, snow, or even watering plants on the deck can accumulate on the surface and provide a suitable environment for mold and algae to grow.
- Poor ventilation: Lack of proper air circulation can also contribute to mold and algae growth on the decking material. If you live in a humid climate or have a lot of trees near your deck, it may be difficult to get enough air circulation across the surface.
- Organic debris: Leaves, twigs, and other organic debris that accumulate on the deck can provide a food source for mold and algae to grow. Always clear away debris after intense or prolonged periods of rain.
- Water pooling: Standing water on the surface of your deck can be a prime breeding ground for mold. To avoid such a situation, ensure your deck is pitched correctly and the drainage pathways are clear.
Step By Step Guide On How To Clean Mold And Algae Off Your Decking
Mold and algae are a health hazard and can leave you and your family exposed to dangerous toxins. Fortunately, it’s relatively simple to clean them off your decking with a few basic cleaning supplies. Here’s a step-by-step guide on how to do it-
Prepare The Area
Remove any outdoor furniture, planters, area rugs, and other objects from your deck to protect them from coming into contact with the cleaning solution. Once your deck is clear, take a broom and sweep off any loose debris and leaves from your deck’s surface and any visible mold and algae. You should also ensure that all the drainage pathways are clear of debris so that your cleaning water can flow off the deck properly.
Gather Your Cleaning Supplies
Here are the cleaning tools you will need to clean mold and algae off your decking:
- Garden sprayer or stiff-bristled brush: You can use a garden sprayer to apply the cleaning solution evenly over the affected areas of your decking. Alternatively, you’ll need a stiff-bristled brush to scrub the deck’s surface.
- A large bucket: You will need a large bucket to mix your cleaning solution.
- Cleaning solution: You can use a solution of one-part bleach to three parts water or a specialized deck cleaner formulated to remove mold and algae. Hydrogen peroxide is also a great alternative to bleach because it’s environmentally friendly and doesn’t produce harmful fumes.
- Garden hose or pressure washer: You’ll need a garden hose or pressure washer to rinse off the cleaning solution once you have scrubbed the deck. The pressure washer is also great for removing stubborn stains and dirt from your deck’s surface.
- Broom: You will need a broom to sweep off any loose debris and leaves from your deck’s surface and any visible mold and algae.
- Protective gear: You should wear gloves, safety glasses, and a mask to protect yourself from the cleaning solution and any mold or algae spores that may become airborne during the cleaning process.
Protect Yourself
Before you do anything, ensure you wear gloves, safety glasses, and a mask to protect yourself from mold and algae spores. Inhaling mold and algae spores can cause respiratory problems, and touching them with bare hands can cause skin irritation, rashes, and even fungal infections on open wounds.
Wear chemical-resistant gloves made of a durable material like nitrile to protect your hands from the cleaning solution and any sharp debris on your deck. It’s also important to wear long-sleeved clothing and pants to protect your skin from exposure to the cleaning solution and debris. Avoid wearing sandals or open-toed shoes, and opt for closed-toe shoes, such as rubber boots, with a good grip to prevent slipping on wet surfaces.
Mix The Cleaning Solution
Using a metal bucket or other non-porous container, mix the cleaning solution according to the manufacturer’s instructions. If you’re using a deck cleaner that contains chlorine bleach, use caution, as bleach can be corrosive and may discolor any objects it comes in contact with.
And if you prefer a homemade solution, use one part laundry detergent, one part bleach, and four parts water. You can also use hydrogen peroxide and water, but keep in mind that this solution is less corrosive and won’t be as effective at removing tough stains.
Apply The Cleaning Solution
Using a garden sprayer or a stiff-bristled brush, apply the cleaning solution to the affected deck areas, saturating the surface evenly. Allow the mixture to sit for 20 to 30 minutes to kill any weeds, algae, and moss that may be present.
Scrub The Deck Surface
Using a stiff-bristled brush, scrub the deck surface to remove any dirt, algae, and mold, paying close attention to areas where the decking boards are nailed or screwed in. For stubborn mold and algae patches, use a pressure washer and an appropriate cleaning solution or detergent to remove them.
Once you’ve completely scrubbed the deck surface, rinse it off with a garden hose or a pressure washer, making sure to rinse off all of the cleaning solution and debris.
Apply A Protective Finish
Allow the deck to dry completely for at least 48 hours before applying a protective finish such as a water sealer or a deck stain to prevent future mold and algae growth. Make sure to read the product labels and directions carefully before applying.
How To Prevent Mold And Algae Growth On Your Decking
Cleaning mold and algae off your deck can be a tedious job, so preventing the growth in the first place is the best way to go. Sadly, there is no magic spell to ensure your deck is free of these organisms, but there are several steps you can take to slow done the growth. These steps include the following-
- Keep your deck clean: Debris, leaves, and other organic materials often hold moisture and provide food for mold and algae, so make sure to regularly sweep and clean your terrace to reduce their growth.
- Provide adequate ventilation: Decks should have at least 1 inch of airspace between the underside and your home’s foundation. This space ensures there is proper airflow, which can help impede mold and algae growth. Remember, mold and algae prefer moist, dark places.
- Use mold and algae-resistant materials: By choosing products that are labeled as being “mold and algae resistant,” such as composite decking, you can help to reduce the risk of mold and algae growth.
- Allow your deck to dry properly after each wash: Most people think the washing process is complete once the deck is dry to the touch. However, it’s essential to allow your deck to completely dry before bringing back your furniture and rags. After an extensive wash, give it a few days to make sure it’s completely dry.
- Perform regular maintenance: Regular maintenance can help to keep your deck clean and free of any potential growth. So, schedule a regular clean every two months during the warmer months to keep your deck looking its best.
