A concrete pool deck is often exposed to water. Although it gets a chance to dry out, certain circumstances can cause the surface to develop mold and mildew. Concrete is naturally porous. Water can penetrate the surface, causing concrete to hold in moisture longer. It creates the perfect setting for mold and mildew to grow and spread.
The Dangers of Mold and Mildew
Mold and mildew can cause concrete to discolor. It will either be green or black, making the surface look dirty and unkempt. It also makes the surface slimy and slippery even if it is topped off with a stamped concrete overlay or a spray knockdown texture coating.
If neglected, it can spread to other areas of the concrete pool deck and it would be a lot harder to clean. It takes more than just scrubbing or washing to take out mold and mildew on concrete.
Removing Mold and Mildew from Concrete
When it comes to cleaning the pool deck, mold and mildew are probably the worst you would have to deal with. It may seem difficult but it is possible. There are two things needed in this process: a mold and mildew cleaner and a concrete sealer.
Cleaning – Choose a cleaner that is designed for mold and mildew. Spray it on the affected area, whisk it with a stiff broom or brush, and powerwash it to remove any trace of mold or mildew. If there are some left, repeat the process until it is all gone. Make sure to store the cleaner in a place that kids and pets could not reach.
Sealing – Air dry the pool deck first before sealing it. A concrete sealer is designed to provide a protective barrier against moisture, dust, and other harmful elements that could penetrate the surface of the deck. A sealed pool deck will resist any future growth of both mold and mildew. It will also make the surface easier to clean and maintain.
Do not let anything ruin your pool deck. It may take extra effort to protect the surface and maintain its appearance and functionality, but it will save you from unnecessary repairs and accidents. Make sure to have your deck inspected for any damage and signs of mold and mildew. Always have a concrete surface sealed to keep harmful elements from wreaking havoc and creating safety hazards.
