If your concrete patio has recently fallen victim to mold, it is important to take steps to get rid of it. Mold growth is unsanitary and it destroys the look of an otherwise beautiful patio. Follow the few simple steps below to quickly get yours mold-free.
Step 1 - Clean First
You will need to give your patio a thorough cleaning before proceeding to remove the mold. Begin by using a vacuum cleaner to remove any caked-on dust deposits, making sure to use a mini vac or feather duster to remove any from crevices or difficult-to-reach areas. You can also use a wet/dry vac in lieu of a vacuum cleaner, as these devices typically work well with concrete surfaces.
Once the dust has been purged from your patio, produce a homemade cleaning solution of mild liquid soap and warm water. Apply it and allow it to set in for several minutes before you give the patio a vigorous scrubbing with a hard-bristled scrub brush. Should you encounter any exceptionally stubborn stains, try using a wire brush instead. Follow up the cleaning by using a garden hose to rinse away any remaining traces of your homemade solution.
Step 2 - Apply Your Bleach Solution
Now that you've removed all the dirt, dust, and debris from your patio, you're ready to begin cleaning off the mold. Begin this step by producing a mixture of one cup of bleach and one gallon of warm water inside of a clean bucket.
When working with bleach, it is recommended that you wear a paper breathing mask and a pair of rubber gloves to protect yourself from overpowering fumes and skin irritation. Also, if you feel yourself becoming lightheaded or weak against the fumes at any point during the process, make sure to take a break far away from your work area, in fresh air.
Now, apply your bleach solution to any areas plagued by mold, and after allowing it to set in for 10 to 15 minutes, proceed to vigorously scrub the mold deposits with the scrub brush. If it proves unyielding, you may need to incorporate the aid of the wire brush again.
Step 3 - Apply Your Finishing Touches
Having gotten rid of all the mold, use a garden hose to rinse off your bleach solution. Once it has been vigorously rinsed, you'll need to dry the surface as much as you can with a clean cloth or paper towels. Moisture is among the leading causes of mold formation, so when performing this step, make a point of being as thorough as possible. Alternatively, if you own a wet/dry vac, this handy tool can be used to instantly suck up any remaining moisture.
