How to Pressure Wash Brick Driveways and Walkways

After build-up years of wear and tear, you may notice unsightly stains and settlement on concrete or brick that can weaken the surface of your driveway. For efficient and fast outdoor cleaning, a pressure washer is a great tool to strip away any stubborn stains. It has more force and power but uses less water than a regular garden hose. Be careful when using a pressure washer because they are designed to clean any substances away from outside surfaces like rooted plants and grime. It is important to know how to handle a pressure washer, and if misused, it could cause an injury.


Materials and Tools Needed For Pressure Washing a Driveway:

  • Broom
  • Pressure washer
  • Pressure-washer detergent
  • Safety glasses
  • Protective gloves
  • Work boots
  • Painter’s tape
  • Tarp
  • Garden hope
  • Waterproof sealer
  • Spray bottle of degreaser
  • Stiff brush
  • Paint roller
  • Paint roller extension

Here are a few simple steps that can help you learn how to pressure wash brick driveways and walkways quickly

Step 1: Prepare and Clean the Surface

Using the broom, clear any loose debris and excess dirt from the surface. If your driveway or walkway is connected to any walls or doors, you may want to cover them with a tarp and some painters tape to protect their surfaces from accidents or flying debris.

Step 2: Read Safety Manual

Thoroughly read your specific pressure washer’s safety manual to ensure you have properly assembled the pressure washer. Each one is different and requires its special preparation and steps.

Step 3: Degrease the Surface

To ensure proper cleaning, you need to spray an even coat of degreaser, keeping a distance of 6 inches from the surface. Applying a degreaser will help loosen stains and allow you to easily pressure it away. After successfully spraying the degreaser, using a stiff brush or attachment tool, scrub the degreaser into the surface.

Step 4: Prepare the Pressure Washer

If your pressure washer came with instructions, follow those to the specific model you are using. You’ll need to connect the spray wand to the washer using a pressure hose. Then connect the washer to a water supply using a spare gardening hose. Turn on the water to make sure it is working. Apply the detergent by using the low-pressure nozzle, and for rinsing, use the high-pressure nozzle. The high-pressure nozzle should not be used on brick surfaces because it can damage them. 

Step 5: Begin Spraying Detergent

Slip-on protective safety gloves and begin to apply the detergent by handling the spray handle. Keep a consistent 8 to 18 inches of distance from the surface. Work back and forth in smooth and controlled strokes. Overlap each stroke by 6 to 8 inches. After completing, let the sprayed detergent sit on the surface for 30 minutes to an hour. 

Step 6: Rinse the Surface

It is time to wash the surface. Switch to the high-pressure nozzle and set to its rinse mode. Start at the higher end of the driveway and work your way down. Point the wand at the surface and squeeze the trigger. Sweep the nozzle back and forth across the surface, like the detergent, and overlap each stroke. For heavier stains, be sure to sweep over them multiple times. Rinse the surface till all the detergent is gone.

Step 7: Seal the Surface

Before you seal, make sure the surface has dried completely. Pour waterproof sealer into a paint pan and assemble the roller to the extender pole. Start in the middle of the area and begin rolling the waterproof sealer out from the middle to all the edges of the surface. The sealant will help protect and keep future stains from appearing. After an even coat to the surface, allow a full 24 hours before using or parking on the surface. 

How to Pressure Wash a Brick Driveway

Brick driveways require different and gentler treatment. When pressure cleaning a brick driveway, you want to soak the driveway down with water. After this, use your most delicate spray nozzle and spray the entire brick surface wet. This doesn’t allow any detergent to absorb in the brink. While wet, apply the proper detergent with nozzle and let it soak for 5 minutes. Attach a rinsing nozzle to remove all the dirt, grime, and detergent. Make sure you don’t destroy the mortar to ensure your brick driveway is still staying strong.
