When it comes to cleaning your backyard brick fence in Melbourne you have several different options. There are two options that we recommend. This is because these two options are the quickest, and easiest.
The first option is by using a pressure washer. This is by far the easier (and most fun) method for cleaning a brick wall.
The second options require a little bit more elbow grease. It is cleaning a brick wall with bleach. Make sure you be very careful if using this method and take safety precautions.
How to Clean a Brick Wall Using A Pressure Washer
- Spray the wall with a low-pressure hose to saturate it. Spray the wall to saturate it with water. The maximum pressure of your hose should not be more than 700 psi. Too much pressure can damage the wall of the brick.
- Add the detergent according to the instructions of the manufacturer. Use a brick-safe detergent to wash your pressure. Check the instruction manual of your pressure washer to find out how to properly add the detergent. In some cases, the solution may be applied directly to the wall without diluting it. To be sure, check the products instruction manual.
- Spray on the detergent solution and leave on for up to 15 minutes (or according to manufacturers instructions). Use the detergent solution in your pressure washer to saturate the wall again. Use a side-by-side sweeping motion to fully saturate the brick wall. Allow the detergent to sit on the wall for up to 15 minutes before rinsing, but do not let the detergent dry on the wall. Make sure you keep the pressure washer at low pressure while you’re doing this.
- Spot any tough stains with a scrub brush. If you notice tough stains or grim spots on the wall after saturating it with a detergent, use a scrub brush to work on them. Apply medium pressure to the brush and rub it back and forth on the stain. You may need to apply some extra detergent solution to these areas to make it easier to remove dirt.
- Rinse the detergent and dirt off the wall. After the time is up and you spot the wall washed, spray the wall with water. Start spraying at the top and move down. Make sure you remove all of the detergents. Go over the wall several times to make sure the detergent is gone. You might want to focus on a small area at a time, rather than spraying the wall all over.
How to Clean A Brick Wall With Bleach
- Mix water and bleach together in a spray bottle. Use approximately 1 part of the bleach for every 6 parts of the water to achieve the right concentration. Shake the bottle to make sure the solution is mixed properly. Keep your spray bottle pointed away from your face at all times. Caution must be observed when handling bleach. It’s going to be a good idea to wear gloves, face masks and eye protection to defend against potential splashes. Dense build-up caused by moss or mould growth is typically resistant to gentler cleaning methods and will require a more intensive strategy.
- Spray the bleach solution on the wall. Apply the mixture liberally to areas of the wall where the moss or mould growth is the densest. Bleach is a potent disinfectant and is mildly caustic—not only will it kill whatever grows on the brick, but it will also eat away at its wall hold. Test the bleach solution at an out-of-the-way spot on the wall to confirm that it won’t ruin the appearance of your brick. Wet the wall thoroughly before you mist it with bleach. This prevents the bleach from soaking in the brick where it can create structural weakness. Be careful not to inhale or contact your bare skin with bleach.
- Allow the solution to sit down overnight. Give the bleach 8-12 hours to take effect for best results. As it sits on the wall, it chokes the growth of the moss or the mould and makes it easier to remove it without the need for a lot of tiresome scrubbing. The longer you allow the bleach to remain on the wall, the better it will be to release sluggish grime.
- Wash the wall with a hose. Once treated with bleach, the moss and the mould should simply be rinsed under a powerful stream of water. Remove any remaining bits by hand using a plastic spatula or scraper, then rinse again. Allow the wall to dry and apply a silane-based sealant to protect against future growth if desired. Dust and spray your brick wall regularly after it has been thoroughly cleaned with bleach to keep the moss and the mould from returning.
