How To Get Rid Of Black Mold On Pool Deck

Concrete Pool Deck Cleaning

How to Remove Mold and Mildew from a Patio (without using a pressure washer)!

Cleaning a concrete pool deck is a pretty straight-forward process. Take the hose and rinse the surface to wash away dirt and debris leftovers away from the pool. Then, take a stiff brush and a water-bleach mix or water-mild detergent mix. When done cleaning the deck, take your time to inspect it and look for cracks. If you find it, it may be best to contact a professional to help you solve the issue. Once you finish all the repairs, use a concrete sealant to finish the cleaning process off.

Use This Bleach Solution

Professional pressure washers use a prewash cleaning mix of bleach, water, and a surfactant. The surfactant prevents the solution from evaporating too quickly. This allows time for the bleach to kill the algae and other undesirables.

You can make your own mix by combining 1.5 cups of bleach and 1tsp of blue dawn dish detergent to a 1-gallon container. Fill the remainder of the container with water.I use a 1-gallon lawn spray because it allows precise application. I can get every spot that I need without getting any overspray on my plants and lawn.

The bleach solution will kill algae almost immediately. It also brightens surfaces and makes concrete and driveways look refreshed.

If you are concerned about bleach causing damage to your plants, you should know that bleach very quickly neutralizes to into salt, oxygen, and water.

Giving the plants and lawn a nice pre-soaking of water. Apply the treatment on a calm and overcast day, and allow it to rest for several hours before rinsing away. This will give it plenty of time to work and plenty of time to neutralize.

Ive been using the bleach solution for years and have yet to experience any negative effects on plants or lawn.

Best For:

Works wonderfully on concrete, stones, and pavers, and other hard surfaces.

Where to Avoid:

Avoid using bleach on stained concrete or on surfaces that you dont want to lighten/brighten. Always do a spot test.

Is Green Mold Harmful

Contrary to popular belief, black mold is not the only type of mold that is harmful. Green mold has dangerous effects on humans who have been contaminated or accidentally ingesting it. They release airborne spores that can cause allergies, asthma, and other related respiratory concerns.

It is not safe to leave mold growths unaddressed, especially if they are located near your home. They have toxins that can even lead to blood poisoning and brain infections. Although it may not necessarily kill you, it can still seriously affect you and your familys well-being.

One Start With A General Cleaning

Ideally, your vinyl deck should be cleaned at least four times per year using Duradek vinyl cleaner which is available from your authorized Duradek contractor or directly from Duradek. Follow the directions on the label.

This cleaner is designed for vinyl and will NOT leave a harmful chemical residue like many household cleaners may. Use warm water and a stiff broom, scrubbing in a circular motion to loosen the dirt. Spray with a garden hose to wash away the loose dirt. Flush thoroughly with clean water.

Note:It is very important to remove all residue from cleaners used on your deck. While the cleaner itself may be gentle enough, it is when the sun bakes the chemicals into the surface that your deck can experience discoloration.

  • Make sure the area is relatively dry. Wear protective gloves and/or goggles if needed.
  • Combine approximately 1 tablespoon of dishwashing detergent with 1/4 gallon of warm, tap water.

  • Preventing Green Mold Moss And Green Algae Growth

    You can save yourself time and money by being proactive – protecting your deck from mold, moss, mildew and algae before it takes hold. Here are a few simple ways to keep unwanted deck growths from moving in:

    • Apply a deck stain or sealer: seal over your deck boards to keep moisture out. Thats a big deterrent for fungi and plants, which need damp environments to survive.
    • Clean your deck regularly: fungi like mold and mildew feed on organic matter – and a deck covered in leaves, pine needles and dirt is like a buffet table for these deck pests. Regularly sweeping debris off your deck will starve out any potential fungal invaders.
    • Choose composite deck boards: one huge advantage of composite deck boards are their protective shells, which keep water from seeping into your boards. Compared to wood boards, composite boards require less cleaning and less maintenance to keep fungi and deck growths away.

    Use A Pressure Washer

    If you have a small amount of mold or algae, you may find that the first two steps of drying out and sweeping the area is enough to remove it. If this is not the case, pressure washing is often quite effective in removing mold and algae from pavers, bricks or concrete.

    If you do not have a pressure washer, you can purchase one relatively inexpensively to have on hand for this and future projects. You can also rent one or hire someone to power wash your surfaces for you. If you are pressure washing paving stone patios, walkways or driveways, you may need to replenish the joint sand between the pavers after cleaning them. This is typically included in a professional clean and seal paver service.

    Pressure washing is often all you need to remove mold or algae from hardscapes, but if this does not work, there are other options.

    Black Mold And Why It Grows In Certain Deck Stains

    How to clean green algae / mould off Decking – Quickest and easiest way to clean Decking

    Moldy Deck

    Exterior deck stains are subjected to the elements making them prone to natural contaminants. A deck stain is there to shield the wood from harsh weather and the damage it can cause such as rot and decay. In providing protection sometimes the deck stain itself can be compromised.

    Black mold is one of the natural occurrences that can affect wood stains effectiveness and longevity. There are several reasons why black mold can grow on or in a deck stain but here are the most common reasons.

    Over Applying Deck Stain

    When a deck stain is over-applied to the wood it can affect the curing or drying time of the stain. When this happens the deck stain remains tacky for several days or longer allowing dirt and tree pollen to become embedded. Once these contaminants have intruded the stain they can attract and begin to grow black mold even after the stain finally cures.

    Tips: To avoid curing issues by over applying a wood stain, work in small areas or one board at a time. Let the stain soak into the wood for several minutes then use a brush or a stain rag to wipe any excess drips or puddles.

    Inexpensive or Cheap Deck Stain

    Going with a cheap deck stain may save you money initially but may cost you more in the long run. Cheaper deck stains consist of a cheap grade linseed oil that lacks the mildewcides that help fight black mold.

    Tips: Do some research and buy a quality deck stain that is not prone to mold and mildew.

    Brush Your Pool Again And Again

    Brush your pool at least 3 to 4 times a week, concentrating on where you first spotted the algae. Remember, black algae has deep roots that can be embedded into your pool walls. It may look like its gone, but its probably still there. Just keep brushing. Continue brushing for several days after you see it starting to dissipate.

    This is, however, not a guarantee. Black algae is relentless and could continue to infect your water. If it does, you know how to kill it, just be more aggressive next time. Perhaps consider an additional dose of acid and chlorine and constant brushing.

    Don’t forget to use some Black Spot Remover to make sure that the not only does the black algae brush off easier, but they stay off as well.

    How Do You Remove Black Algae From Concrete

    Scrub and loosen the black algae on the affected concrete, using the push broom with short strokes and heavy pressure. Prepare a strong detergent solution. Saturate the black algae with the solution without any of it spilling over onto nearby plants. Leave the bleach solution to sit for 20 minutes.

    Can Black Mold Damage My Deck

    Black mold isnt just unsightly. If left unchecked, it can and will eventually destroy a deck as black mold is usually accompanied by wood-eating fungus.

    Black Algae Treatment, Get Rid of Black Algae in Your Pool

    Care needs to be taken when using cleaning products with composite wood to avoid damaging the deck. Pressure washers should never be used on composite decking as the force of the water can easily imprint the plastic in the decking, ruining it.

    Its also a bad idea to use bleach on decking. Most composite decking manufacturers warn that bleach will discolor their products, especially if used in sunlight. Chlorine bleach can also affect the composition of the decking, causing it to crack or chip prematurely.

    Instead, use a mix of dishwashing liquid and water, which will remove the mold but is mild enough not to harm the deck. As with cleaning stained and painted decking, apply vinegar with a spray bottle after cleaning to prevent future mold growth.

    Protecting Plants During Treatment

    Since I am listing several chemical treatments to get rid of algae and/or mold and mildew, I feel it is important to stress the need for plant protection. Each option listed above will present its own unique potential for damaging your plants. You will need to judge which option is safest.

    However, it is incredibly important that you always do a pre-soaking on your plants and/or lawn when using any chemicals. The water will help to protect leaves and to saturate the soil in an attempt to dilute any runoff.

    It is also important that you be mindful of the direction of your water runoff and act accordingly. Focus most of your pre-soaking on areas that will receive the brunt of runoff.

    Always use a controlled application container, such as this lawn treatment sprayer.* And always do your treatments on calm days. Any breeze can carry mists of chemicals to plants that you want to protect.

    Cleaning Solutions That Remove Algae

    When it comes to removing algae from your wooden deck, you have quite a few options. The most common youll hear is bleach, but bleaching your deck can alter its color and even corrode the metal fasteners keeping your deck together. For these reasons and more, bleach is not recommended by the Occupational Safety and Health Administration for algae and mold removal.

    If youre looking for alternative algae cleaning solutions, here are a few suggestions:

    • Moss and algae removal products: There are quite a few different products on the market that are designed specifically to remove moss and algae from decks. Many of these products allow you to wet it and forget it, but tend to be more expensive than DIY cleaning solutions.
    • Hydrogen peroxide: Another cleaner you probably already have in your home is hydrogen peroxide. However, its important to understand that hydrogen peroxide alone wont kill algae growth instead, it creates a foamy surface that helps lift the algae away from the surface, making it easier to scrub away.
    • White distilled vinegar: White vinegar is a popular natural cleaner that can be used both inside and outside. Simply combine one gallon of water with one cup of white vinegar and scrub the deck with the solution to remove algae, mold, and mildew.
