Learning your deck has attracted unwanted mold and algae can be disheartening but it is not the end of the world. These contaminants can be removed to reveal a beautiful surface once again. How to remove mold and algae from decks is a common question asked by homeowners. But with the right knowledge, it can be done over a weekend with no problem.
The key to removing mold and algae from decks is using a quality deck cleaner. Deck cleaners are designed to loosen debris like dirt and gray wood fibers and also rid the deck of contaminants like mold and algae. If the proper cleaner is not used then the mold and algae will continue to grow and will reappear in no time. A deep clean is necessary to get to the root of the mold and algae spores. Not only will a good deck cleaner remove these problematic pollutants, it will also help deter them from coming back so quickly. This is especially important if you are staining the deck. Improper cleaning can mean mold and algae get trapped below the new deck stain and begin to eat away at the wood causing rot and decay.
Apply the deck cleaner thoroughly to the surface as directed. Allow the cleaner adequate time to work. Remove the loosened soil and contaminants with a pressure washer or scrub brush. This should remove any mold, algae, mildew, and graying to reveal clean bare wood. Once the mold and algae have been removed from the deck it can then be stained if desired. Certain deck stains can actually help prevent mold and algae from returning so quickly. However, over time if the pollutants reoccur simply wash the deck again in the same manner. Normally every couple of years the deck should be cleaned for maintenance. The key is to not let mold and algae take over but to clean it often enough to prevent it.
