Remove mold from the wall

One of the elements that would be recommended is pressurized water, since any technique that we use will give us more satisfactory results if we manage to rinse with plenty of water and the pressure of a pressure washer, Apart from the convenience of rinsing, it will save us a lot of manual brushing action which is always essential.

Whether cleaning mold from floors or walls, the cleaning efficiency of a pressure washer is guaranteed by the pressure and flow of the water. An ordinary garden hose can vaporize 10 atmospheres of water at a rate of a few milliliters per second., and the trick of “choking” the pipe with your thumb will not help. However, with a pressure washer we can reach pressures of hundreds of bars and flow rates much higher than those that conventional taps can provide.

These are “weapons” that allow you to fight scale, mold and moss. I recommend you ask a friend or neighbor to tell you about one of these machines, or if you prefer, you can search for one of the best pressure washers and buy your own.

Clean mold with natural products

Mold can be effectively eliminated with certain natural products. The most useful and easy to find is baking soda, a natural bleach and fungicide that can be mixed with lemon juice (or other citrus extracts), hydrogen peroxide and essential oils to create a very powerful natural mold inhibitor.

Let’s see 2 basic recipes that we can prepare at home:

Recipe 1

  • 2 tablespoons baking soda
  • 700ml water
  • 2 tablespoons fine salt
  • 2 tablespoons hydrogen peroxide (30 or 40 rolls)

To use, dissolve baking soda and salt in water and pour into a spray bottle. Now add the hydrogen peroxide and gently shake the spray bottle.

Recipe 2

  • 1 cup of water
  • ½ cup white vinegar
  • 1 tablespoon baking soda
  • 5 drops of lavender essential oil
  • 5 drops of lemon essential oil

The mixture should be prepared by first dissolving the baking soda in the water, then adding the vinegar and finally adding the essential oil. Mix well and place in a container fitted with a sprayer and ready to use. Either way, just apply it to the mold-affected surface and let it sit for a few hours.

This compound imparts a pleasant aroma thanks to the action of the essential oil, which it also has antibacterial properties and counteracts the formation of mold, while bicarbonate has a strong whitening effect. This solution softens the layers of the mold and facilitates their separation. It is very important to gently shake the mixture before use.

In some cases the mold is more localized and a cleaning paste can be used. In this case, one can mix equal parts baking soda, salt and hydrogen peroxide, apply in a fan, leave for a few hours and rinse thoroughly with water, preferably with a pressure washer.

Cleaning to remove mold from the wall

Whether your exterior is brick, wood, vinyl siding, concrete, etc. Mold growth may occur. Even if you treat the exterior walls with a fungicide, as you often do with wood paint to prevent rot, mold can easily grow in joints and corners.

Relatively easy to remove, a hose with enough pressure will kill mold in no time, be sure to run the residue down the drain or after sweeping, or you’ll promote its growth in other areas. It is recommended to regularly clean the exterior walls with a hose to prevent the accumulation of organic matter on the exterior walls.

The frequency of exterior wall cleaning depends on several factors. If parts of the facade are in dark or very dark areas, then you need to water once a month. However, in areas exposed to the sun, mold is less likely to develop, so cleaning twice a year is sufficient.

Keep in mind that mold tends to show up in seams and corners, since this is where organic matter is most likely to settle, you should therefore pay attention to the lower areas of the facades, the areas behind the gutters and awnings, etc. If you let the mold problem slide, you’ll end up with a big black stain on your exterior wall that’s hard to remove, so the key is to not let the problem slide and find a solution when it’s easy to fix. .

How to Prevent Mold

As with everything, prevention is better than cure. To prevent mold from forming, it is ideal to apply a mixture of water and vinegar to the walls every four months, which will naturally disinfect the walls and eliminate most bacteria that can cause mold. In addition to watering, there are other ways to help prevent mold from forming on your facade.

  • Keep trees, plants and shrubs close to the facade well pruned and try not to let the branches get too close or touch it. This keeps the facade more airy and prevents the accumulation of organic matter on it, which makes it difficult for mold to appear.
  • Avoid directing sprinkler systems toward your home, as humidity can increase the risk of mold and mildew growth.
  • When laying the coating, ask your installation company what they would recommend to prevent mold growth.
  • Prevention is better than cure. Seeing mold anywhere in your home, inside or outside, is a detrimental situation as it can cause additional problems. With proper prevention and treatment, you can keep your outdoors clean and provide a safer environment for your family.
