Step to Follow on How to Get Rid of Black Mold on Pool Deck
Step One: Make Sure the Mold is Black Mold
Mold, in general, needs heat energy to grow. Therefore, black mold tends to appear on surfaces that are cooling down or wet for an extended period. This means pools after swimming and decks around pool areas are prime candidates for black mold growth.
To check if your deck’s black mold is truly black mold, take a small amount of the mold between your fingers and strongly rub it. It is not true black mold if it comes off on your skin or you see smears. It may be another type of surface fungus, but you should still treat it using the same methods as the true black mold.
Step Two: Clean the Pool Area
Start by scrubbing the deck with a stiff brush. Scrubbing will remove any mold or dirt that might be holding it to the surface and remove any dead mold spores. Do not use soap because it can react with any leftover chlorine in the water and become toxic.
You also do not want to use a power washer because the water under pressure could push the mold into the wood and make the issue worse by allowing it to penetrate more deeply. If you want to use a power washer, use the lowest pressure setting and make sure to dry off the deck afterward with a towel.
Step Three: Treat Black Mold on Pool Deck
Next, mix one cup of bleach in one gallon of water and apply directly to any visible or suspected mold patches using a spray bottle or garden sprayer. You will need to reapply the bleach every day for three consecutive days regardless of whether you see any black mold returning or not.
If at any point during treatment you start seeing growth again, then repeat the process further. Cleaning the deck with regular soap is inadequate because most soaps do not affect mold spores once they are dry. Bleach is a powerful oxidizing agent, which will kill mold spores and help to prevent new spores from growing.
Step Four: Keep the Mold Away
While bleach kills surface mold, it also destroys paint and can cause damage to decks painted with acrylics or water-based latex paints. If you live in an area where rain is scarce for much of the year, then painting your deck with water-based paint is an excellent way to prevent mold from returning.
You also need to remember that bleach can be hazardous if you breathe it in or get it on your skin or clothes. So wear rubber gloves and safety goggles when applying bleach as well as during any cleaning afterward. It may sound a bit extreme for a deck, but safety first will prevent more serious problems from occurring.
Step Five: Be Patient
You may have heard mold can be removed from a surface in as little as twenty-four hours. In reality, it takes much longer because the bleach needs time to kill all of the spores. This means you should treat black mold on your pool deck for at least seven days, even if you do not see any more black mold returning after one day.
If the black mold on your pool deck is still there after one week, treat it again with bleach for another seven days. If you still see mold after that point, treating the surface again is unlikely to result in any different outcome. In this case, you will need to replace your deck boards. This will help in how to get rid of black mold on pool deck.
Step Six: Prevent the Mold from Coming Back
If this is your first bout with black mold on your pool deck, then you may be able to prevent future growth by painting the deck with acrylic or water-based latex paint. However, if you have already tried this and still see new patches of black mold, the most likely cause is that there was not enough bleach on the surface to kill mold spores growing on the underside of the deck boards.
In this case, you will need to remove all of the damaged boards and place them in a pile to avoid touching any other deck boards. Then treat your entire pool deck with bleach until it runs off the sides of the pool decking, wait at least seven days, and replace the boards.
Step Seven: Replace Deck Boards
Use a chisel, flat bar, or stiff paint scraper to pry up the deck boards. Please place them in one pile so that you do not accidentally glue or nail them back down where they are touching any other deck boards. Once you have all of the extra boards out of the way, treat the entire pool deck with bleach, waiting at least seven days before you replace the boards.
If your pool deck is small enough to tackle by yourself, it is possible to do the job in one day. If not, treat all of the moldy boards with bleach for at least ten days before removing them. The strength of bleach diminishes after ten days, which means that you risk contaminating the soil or nearby bodies of water if you try to remove all of the boards at once.
The most important thing to remember is that you don’t want the mold to come back. However, if it does, there are more drastic measures like taking out all the wood and replacing it with fresh lumber or tearing down your deck altogether.
Be sure to follow these simple steps for prevention if you notice black mold on your pool deck again! The conclusion paragraph is informative and provides information on how to get rid of black mold on pool deck.
