Deck mildew is not only common but can spread quickly. One of the main problems with owning a deck is that mildew is a very common occurrence. Mildew will grow even faster on a deck that is located in an environment that gets a lot of moisture and bouts of heat.
If you own a pool or hot tub then deck mildew is also most likely going to be a problem. Moisture from rain and snow will seep into the grain of the wood and the result, over time, will be mildew. It is important that mildew is dealt with properly as it can rot the wood that the deck is made from but also lead to the formation of mold. The information contained in the article below will share with you tips on how you can prevent deck mildew from forming and being a problem.
1. Remove Dirt
Considering that if a deck is located outside it is also reasonable to believe that the deck will become dirty. This can be anything from falling leaves to mud that you inadvertently tracked on the deck. Either of these things can easily cause mildew to grow. As the elements attack the wood and the leaves and dirt decompose, the mildew will take hold.
Always use a broom to push off any water that is left on the deck. Also be sure to do the same with any leaves or debris. If you choose to use a hose to help with the process make sure you brush away the water when you are finished.
2. Replace and Repair
If mildew is left too long on a deck it will eventually turn into mold and will then eat away at the structure of the wood. Once deck mildew has gone this far you will have a structure that is unstable and dangerous in parts. It is important to replace any planks that are covered in mold or are rotting as a result of mildew. The initial instinct is to simply clean the mildew away but once it has gotten in the grain there is not much you can do to salvage it.
3. Special Cleaners
Deck mildew can be prevented if you wash the deck regularly with a special homemade solution. Mix together a bucket of water with one cup of bleach per gallon. To that add vinegar and baking soda. Use a mop to clean the deck with the solution. This will not only clean the deck but also kill any signs of mildew that you may have spotted. To stop the chemical reaction use plain water and then brush it off the deck so it can air dry.
4. All-Weather Sealant
Owning a wood deck is an invitation for mold and mildew to grow on the surface and eventually eat away at the wood. Deck mildew is easily prevented by covering the deck with a sealant that is waterproof as well as mildew and mold resistant. When you apply the sealant make sure you do so under the deck if possible.
