10 Step-by-step Guidelines on How to Power Wash Fence

Step 1: Prepping the Area

First things first, cover any surrounding plants and surfaces in plastic sheeting or a drop cloth to protect them from the power washer. Use duct tape to secure it all in place if necessary.

Cover Any Surrounding Plants

You wouldn’t want to accidentally chip away paint or damage neighboring surfaces in the process of cleaning your fence. It’s always better to take precautions before you start. This step is crucial to avoid any collateral damage. Before you start, make sure there are no electrical outlets or cords around the area.

Step 2: Preparing the Pressure Washer

Connect your electric or gas-powered pressure washer to a water source with a garden hose. Ensure that all connections are tight so there are no leaks when you turn it on.

It will also be a good idea to test out the pressure washer first by spraying it on an inconspicuous area to ensure it’s working properly. You don’t want to switch the machine on and realize that it needs repairs in the middle of cleaning your fence.

Step 3: Adding Detergent

Choose a biodegradable detergent that is safe for plants and pets. Add the specified amount of detergent into the pressure washer’s soap tank or attach a separate detergent container. It’s always better to use environmentally friendly detergents than harsh chemicals that might harm your plants.

But if your fence is extremely dirty, you might need to use a stronger detergent. In that case, make sure to test it on an inconspicuous area first. This will help you determine the appropriate concentration to use without damaging your fence.

Step 4: Choosing the Right Nozzle

The nozzle tip you use will determine the strength and spread of your water stream. Use a 25-degree nozzle or a 40-degree nozzle for cleaning your fence, depending on the level of dirt and grime build-up. It’s always safer to start with a wider-angle nozzle and then switch to a more concentrated one if necessary. You can also use the soap nozzle for tough stains or mold buildup.

Step 5: Starting at the Top

Starting at the top of your fence, hold your pressure washer wand at a 45-degree angle and begin spraying in broad strokes. Make sure to keep a consistent distance of about 1 foot away from the fence throughout the process. However, remember to adjust the distance as necessary if your fence is softer or weaker than usual. You don’t want to blast away chunks of wood in the process.

Step 6: Power Washing Your Fence

Continue moving your power washer down your fence in a sweeping motion while maintaining a steady pace. It’s important to not linger on one spot for too long as you could end up causing damage to the wood. It’s also important to not neglect the bottom of your fence, which is usually more susceptible to dirt and grime buildup.

Step 7: Hard-to-Reach Areas

For areas that are harder to reach, use a scrub brush with a long handle and manually scrub while spraying with your pressure washer. This will ensure that all parts of your fence receive equal amounts of cleaning. You can also use the scrub brush for tough stains or mold buildup. But if the stains are too stubborn, you can switch to a narrower nozzle for more concentrated cleaning.

Step 8: Rinsing the Fence

Once you have gone over your entire fence, it’s time to rinse off any remaining dirt or detergent. Switch your nozzle tip to a 25-degree setting and start at the top again. It’s important to thoroughly rinse off all the detergent to avoid leaving any residue on your fence. But at the same time, make sure to not cause any damage by blasting high-pressure water directly onto your fence.

Step 9: Finishing Touches

After rinsing, switch the nozzle tip to a 40-degree setting and go over your fence one last time for an overall clean finish. You can also use this time to inspect your fence for any remaining dirt or stains. If necessary, go over tough spots with the scrub brush again. Always remember to keep a consistent distance and not linger in one spot for too long.

Step 10: Drying Your Fence

Allow your fence to dry completely before applying any paint or stains. This will ensure that the wood has absorbed all the excess moisture and will allow for a smooth application.

For quicker drying, you can use a leaf blower or allow for natural air drying. Once your fence is completely dry, you can admire the end result – a clean and fresh-looking fence that adds to the overall aesthetic of your home.

Following these steps on how to power wash fence will guarantee a beautiful and clean fence that will make you the envy of all your neighbors!

Remember to always take safety precautions, wear protective gear, and test out the pressure washer before starting. With these tips in mind, power washing your fence has never been easier. So go ahead, bring new life to your old wooden fence with power washing!
