Can You Power Wash Brick House Exteriors? Dos and Don'ts

Can you power wash brick? Understanding the versatility and effectiveness of power washing encompasses various surfaces, among which brick holds a prominent position. Power washing, a high-pressure water-based cleaning method, offers an appealing solution for reviving and cleaning different surfaces; brick is no exception.

Addressing Safety Concerns of Power Washing Brick:

Water Pressure: Power washers generate high-pressure streams of water, which can cause injury if not handled properly. When using a power washer on brick surfaces, it's essential to adjust the pressure settings to a level that effectively cleans without damaging the bricks or causing harm.

Protective Gear: Ensure you wear appropriate safety gear, including goggles, gloves, and sturdy footwear, to protect yourself from debris and potential splashes.

Electrical Hazards: Be cautious of electrical outlets or wires near the power-washed area. Keep the power washer away from these elements to avoid electric shock.

Slippery Surfaces: The water used during power washing can make surfaces slippery. Take precautions to prevent accidents, such as placing warning signs and cordoning off the area until it's dry.

Suitable and Unsuitable Brick Surfaces for Power Washing:

Suitable Surfaces: Solidly constructed brick surfaces in good condition, such as exterior walls, walkways, or patios, are generally suitable for power washing. Ensure the mortar is in good shape and not crumbling.

Unsuitable Surfaces: Avoid power washing fragile or damaged brick surfaces, as the high-pressure water can exacerbate existing issues. Avoid using a power washer on historical or delicate bricks, as it can cause irreversible damage.

Potential Risks and Precautions:

Damage to Bricks: High-pressure water can chip or erode brick surfaces, especially if the bricks are old or fragile. Test a small, inconspicuous area first and adjust the pressure as needed to avoid damage.

Mortar Damage: Intense water pressure can dislodge or damage mortar between bricks. Check the condition of the mortar beforehand and avoid direct spraying at mortar joints to prevent weakening or dislodging.

Chemical Cleaners: Some cleaning solutions used in power washing may be too harsh for certain types of bricks. Check manufacturer guidelines and use mild detergents to avoid discoloration or damage.

Environmental Precautions: Consider the environmental impact of power washing. Use eco-friendly cleaning solutions and be mindful of where the runoff water goes, ensuring it doesn't harm plants or enter storm drains.

Is Power Washing Safe for Brick?

Impact of Power Washing on Brick Structures:

Abrasion Potential: Brick surfaces vary in hardness and composition. High-pressure water can potentially erode softer bricks or damage mortar if not used properly.

Water Pressure: Adjusting the pressure is crucial. Excessive pressure can force water into the brick's pores, leading to moisture retention and potential structural damage over time.

Cleaning Agents: Some detergents or chemicals used in power washing might affect the integrity of the bricks or the mortar. The wrong cleaners can cause discoloration or erosion.

Factors Influencing the Safety of Power Washing for Bricks:

Pressure Settings: Using the right pressure setting is key. Lower pressure settings combined with wider nozzles can minimize the risk of damage.

Distance and Angle: Maintain a safe distance from the surface and an optimal angle to prevent direct, forceful impact on the bricks.

Testing: Before full-scale cleaning, test a small, inconspicuous area to determine the impact of the power washing on the specific brick type.

Experience and Skill: Professional expertise matters. Trained individuals understand how to handle different brick compositions and adjust the power washing accordingly.

Steps for Power Washing a Brick Surface

Preparing the brick surface for power washing:

Clear the area: Remove any obstacles, debris, or furniture from the area you'll be cleaning. Cover nearby plants or delicate surfaces to protect them from the pressure washer.

Inspect the surface: Check for any cracks, loose mortar, or damage to the bricks. Repair any damages before starting the power washing process to prevent further deterioration.

Soak the surface: Before power washing, wet the surface with water. This helps to loosen dirt and makes the cleaning process more effective.

Necessary equipment and tools for power washing brick:

Pressure washer: Choose a gas or electric pressure washer with an appropriate psi (pounds per square inch) for bricks. Lower psi (around 1500-2000) is suitable to prevent damage to the bricks.

Nozzles: Use a 25- or 40-degree nozzle for brick surfaces to distribute the pressure evenly without causing damage.

Safety gear: Wear safety goggles, gloves, and sturdy footwear to protect yourself from debris and high-pressure water.

Cleaning solution: Use a brick-safe detergent or cleaning solution specifically designed for pressure washers.

Step-by-step guide for safely power washing a brick surface:

Set up the pressure washer: Connect it to a water source and plug it in (if electric). Test the spray pattern on a small, inconspicuous area to ensure it won't damage the bricks.

Apply the cleaning solution: Fill the detergent reservoir or use an appropriate attachment to apply the cleaning solution to the brick surface. Let it sit for a few minutes to break down dirt and grime.

Start power washing: Begin at the lowest pressure setting and hold the nozzle at a consistent distance (around 12-18 inches) from the surface. Use sweeping motions, overlapping each pass to ensure even cleaning. Work from top to bottom to prevent streaks.

Rinse thoroughly: Once you've cleaned the entire area, switch to a plain water nozzle and rinse the surface thoroughly to remove any remaining cleaning solution.

Tips to prevent damage and ensure effective cleaning:

Maintain a safe distance: Keep the nozzle at a safe distance from the surface to avoid chipping or damaging the bricks.

Work systematically: Divide the area into sections to ensure complete and even cleaning.

Avoid high pressure: Use low to medium pressure to clean brick surfaces. High pressure can cause damage by eroding the mortar or chipping the bricks.

Regular maintenance: Consider power washing your brick surfaces annually or as needed to maintain their appearance and prevent excessive buildup of dirt and grime.

Can You Power Wash Brick Houses?
