Removing mold from your wooden decking Canberra or Canberra pergolas

Although mold is a pretty common occurrence on most wooden decks in Canberra homes, there is no permanent solution to it at least not yet.

Step 1 Cleaning the wooden Canberra decking suppliers

To remove mold formation from your wooden decking, you need to first clear your deck of all furniture including flower pots and other decorative fixtures.

Step 2 Scrubbing the mold off your wooden deck and pergola

Use a hard broom to sweep your wooden decking clear of any dirty and mud particles. Then you need to get down on your hands and knees and use a stiff brush over the entire Canberra deck plans. Give special attention to corners and underside of the skirting as this is where mold and algae have a good grip.

Step 3 Chemical application

If you are satisfied that your decking and pergola is clear of mold buy an algae removing chemical from your local decking contractor. You need to do this because despite the scrubbing, microscopic colonies of algae will still exist and unless you clear them out with a strong anti-algae product, it will once again take hold over your entire wooden decking.

Step 4 Buying the right chemical or product

Anti-algae products are available in two options regular (factory made chemical), and environmentally friendly (usually produced from natural sources). Whichever product you select, read the instruction carefully as most anti-algae products come in concentrated form and need to be diluted before application.

If you are in doubt, seek the advice of your local decking supplier of which, there are many available in Canberra. Most would be happy to come over and look at your decking before advising you on a choice of anti-algae product.

Step 5 Application

Brush or lightly spray the chemical so it covers the entire wooden decking. You will usually need to leave the decking alone for a couple of days so as to allow sufficient time for the chemical or anti-algae product to do its job. Follow instructions mentioned on the product package.

Some owners of Canberra homes remove mold the old fashioned way using bleach in a water solution. While this is a low-tech, low expense approach, it has the potential of causing some damage to your expensive wooden decking.
