How To Use A Power Washer To Clean A Brick House

Power washing a brick house can be an arduous task. There are many different types of bricks, mortar, and stone to deal with; each one requiring a different approach. For example, sandstone should never be pressure washed because it will chip or even crumble under force.

The type of brick is also important as the surface texture is what dictates how much water needs to be applied to avoid damaging the brick while maintaining sufficient cleaning power. This blog post will highlight some tips on how you can make your job easier when pressure washing a brick home.

A pressure washer is a type of power tool that uses water under high pressure to remove dirt and grime from surfaces. Using a pressure washer can make your brick home look new, and it’s an easy way to get rid of tough stains. It will also kill any mold, mildew, or algae (such as black spots) on the brick house walls.

There are different types of pressure washers. They perform best for cleaning, washing, sandblasting, sanitizing, and even degreasing surfaces in a matter of minutes.

Safety Precautions Before Pressure Washing Brick walls And Sidings

  • Clean up any loose debris on the ground and around the house. Make sure the area where you will be working is safe and free of debris.
  • Ensure that there are no people or animals nearby when you’re washing your house as they may get hurt by the high water pressure.
  • Make sure you stay safe while pressure washing brick walls and house! Always wear long pants, closed-toed shoes, and any other protective gear that you may need in order to prevent injury from the dirt or debris in your home. Gloves are usually recommended as well for added protection against sharp objects.
  • Always keep an eye out for any cracks in the surface of your bricks – if it’s too deep, don’t continue cleaning those areas until they’ve been repaired.

A Good Washer Is Important For Pressure Washing Brick Walls

  • The first thing you need to do is find a pressure washer that has enough power to clean the brick.
  • You can use a good gas pressure washer for power washing your home walls but at the same time, a precise and quality electric power washer like Sun Joe SPX 3000 can also do this task with great efficiency.

How much PSI do you need to power wash your brick home?

  • PSI is a crucial factor when it comes to choosing a pressure washer for brick washing and cleaning. Right here, people often do something wrong. It’s possible that you will damage your brick walls if you use a high PSI pressure washer like 4000PSI or more.
  • Therefore experts recommend a pressure washer with a PSI ranging between 800 and 2000 PSI. If you have an electric pressure washer for deck cleaning, you can easily use it on your brick walls. In any case, avoid exceeding 3200 PSI when using different pressure washers.

Always patch the mortar near cracks before pressure washing

The preparation of the brick walls prior to pressure washing is extremely important. Why? Because it is not a good idea to let water penetrate into its inner surface. The wall can suffer huge damage if this happens.

Mortar is the material that is used to fill the gaps between bricks and is usually a type of cement or concrete. Brick mortar is prone to damage over time so before starting, you must inspect the bricks for missing mortar or any cracks. It is important to always patch mortar near cracks before pressure washing a brick wall. If you don’t, the water pressure can cause the mortar to crumble and the bricks to fall off.

This is a common problem with older brick walls, and it can be a real hassle to fix. So, make sure to take the time to patch the mortar before you start pressure washing!

For best results perform this task almost 5 to 7 days before you want to pressure wash your home.

Pressure Wash Your Brick Walls In Simple Steps

When it comes to how do you power wash brick home, there are several steps that should take in order to safely clean the exterior of your home. If done improperly, pressure washing can cause damage and permanently discolor your home. Here’s how to pressure wash a brick house properly:

Wet The Brick Wall

Soaking your brick walls is important before pressure washing it. This is great to prepare the surface for cleaning so there won’t be any issues with streaking when applied to a wet or damp area of the house. Below are tips to wet the wall properly:

  • When spraying your house, start from the bottom going upwards. This way you can ensure an even application of water that will not run down unevenly and not cause streaking.
  • When using your pressure washer on bricks, use a low-pressure setting and work in small sections at a time.
  • If your bricks have never been cleaned before, start with a high water temperature so dirt can come off more easily without damaging them. Moreover, this may clean your walls without using any chemicals.
  • Spray down all surfaces of the brick until they are clean. If you are not satisfied, apply a soap solution recommended for pressure washing to remove dirt, mold, algae, lichens, and other substances that can be harmful to your home’s exterior.

Apply Detergent For Thorough Cleaning Of Walls

Cleaning walls can be a tedious task. It becomes more difficult if the walls are stained and dirty. In such a case, applying pressure washer detergent can be of great help. Detergent can easily remove all the dirt and stains from the walls and make them look clean and new.

Always choose a compatible soap or detergent for your walls. Incorrect detergent can damage your bricks and mortar.

Before applying the detergent, it is important to test it on a small area of the wall. If the detergent is not causing any damage to the paint or wallpaper, it can be safely applied on the entire wall. It is also important to avoid using too much detergent, as it can make the cleaning process more lengthy.

Now give it a time to sit properly for 8 to 10 minutes at least. This will help the bricks and wall to soak the soap well so that the dirt and grime can loose completely.

Use a Scrub Brush To Remove Tough Stains

Use a scrub brush to clean areas that are caked with dirt or loose paint. This is an additional option to get better results. Oil, grease, mold, and moss are difficult to remove with mere water pressure. Using a rotary scrubbing brush along with a good brick and mortar detergent can ease your job. Scrubbing helps greatly to loosen this type of stains with less effort while power washing your house.

Rinse the Wall With A Delicate Pressure

Now that the soap has done its job, rinse off detergent and residue from bricks using a delicate pressure for safety of your wall. This is too much important because high pressure can damage your walls. Follow these tips to rinse your wall properly:

  • Start pressure washing using a lowest pressure setting and gradually increase the setting until you deem it good for your wall.
  • Wash the bricks from top to bottom to remove soap and residue.
  • Move-in circular motions while spraying off on tough stains so that the wall remains safe from the constant pressure.
  • Work your way around until all sides of the house have been cleaned.
  • If you think some spots and stains are missed then wait for the wall to dry completely before applying another coat of soap. As you can not judge the stains if the bricks are still wet.

Apply Brick And Mortar Sealant After Power Washing

After pressure washing your home, it is important to seal the bricks and mortar with a quality sealant. It will help to protect the bricks and mortar from future staining and damage.

There are a few different types of brick-and-mortar sealants available on the market. You will want to select one that is specifically designed for masonry surfaces. Be sure to read the instructions carefully, and follow all safety precautions.

Apply the sealant in a thin coat, using a brush or roller. Allow it to dry completely before applying a second coat.

Inspect The Walls After Power Washing

Inspect each surface of your home before you leave to know it is safe to enter your home again.
