Pressure washing is a fast and effective way to clean outdoor surfaces, and PVC decking is no exception. PVC decking is a popular choice for homeowners due to its durability, low maintenance, and resistance to rot and insects. However, like any outdoor surface, it can accumulate dirt, grime, and mildew over time, making it necessary to clean it periodically.

Pressure washing a PVC decking requires some preparation and the right technique to avoid damaging the surface. In this article, we will guide you through the steps to pressure wash your PVC decking safely and effectively, so you can restore its original beauty and prolong its lifespan.

Step 1: Prepare the Area

Before you begin pressure washing, it’s important to prepare the surrounding area. Remove any furniture, plants, or decorations from the deck to give yourself enough space to work. Cover nearby plants and shrubs with plastic sheets or tarps to protect them from the pressurized water and any cleaning solutions you may use.

Start by sweeping the deck to remove loose dirt, leaves, and debris. Next, give the decking a thorough rinse with a garden hose to remove any remaining loose dirt. Be sure to spray the water in the direction of the deck boards, following the grain, to prevent any potential damage.

Step 3: Apply Cleaning Solution

Depending on the level of dirt and grime on your PVC decking, you may want to use a cleaning solution to help break it down. There are various commercial deck cleaners available, or you can create a homemade solution using mild detergent and water. Apply the cleaning solution to the deck surface and let it sit for a few minutes to penetrate the dirt.

Step 4: Pressure Wash

Now it’s time to pressure wash the PVC decking. Use a pressure washer with a fan or wide-angle nozzle, as a narrow nozzle can dig into the deck surface and cause damage. Hold the pressure washer wand about 12-18 inches above the deck surface and work in a sweeping motion, starting from one end and moving towards the other. Keep the wand moving at a steady pace to avoid streaking or uneven cleaning.

Remember to work in small sections to ensure thorough cleaning and to prevent the cleaning solution from drying on the deck surface. After pressure washing, give the deck a final rinse with a garden hose to remove any lingering cleaning solution.

Following these steps will help you pressure wash your PVC decking safely and effectively, leaving it looking clean and vibrant. Remember to always read the manufacturer’s guidelines for your specific decking product and consult a professional if you have any concerns or questions.

Preparing for Pressure Washing

Before you begin pressure washing your PVC decking, it’s important to take some time to prepare the area and gather the necessary supplies. Follow these steps to ensure a successful cleaning process:

1. Clear the deck

Remove any furniture, plants, or other items from your PVC decking. This will give you a clear and unobstructed workspace.

2. Sweep the deck

Use a broom or brush to sweep away any loose dirt, leaves, or debris from the deck surface. This will help prevent clogging the pressure washer and provide a better cleaning result.

3. Cover delicate plants and surfaces

If you have any delicate plants or surfaces near your PVC decking, cover them with plastic sheeting or drop cloths. This will protect them from any potential damage caused by the pressure washer’s spray.

4. Inspect the decking

Take a close look at your PVC decking for any signs of damage or loose boards. If you notice any issues, it’s best to address and repair them before pressure washing to avoid further damage during the cleaning process.

5. Gather supplies

Make sure you have all the necessary supplies for pressure washing, including a pressure washer with an appropriate nozzle for PVC decking, a garden hose, and a cleaning solution specifically formulated for PVC surfaces. Additionally, consider wearing protective clothing, goggles, and gloves to protect yourself during the cleaning process.

By properly preparing your PVC decking before pressure washing, you can ensure a more effective and efficient cleaning process and maintain the integrity of your deck for years to come.

Gathering the necessary equipment

Before you begin pressure washing your PVC decking, it is important to gather all the necessary equipment. Having the right tools and materials will ensure that the job is done efficiently and effectively.

Here are the essential items you will need:

Pressure washer: Invest in a high-quality pressure washer with a PSI (pounds per square inch) rating suitable for cleaning PVC decking. Make sure it has adjustable pressure settings to prevent damage.
Nozzle: Use a wide-angle nozzle or a fan tip to distribute the pressure evenly and avoid concentrated streams that can cause damage.
Cleaning solution: Select a PVC-safe cleaning solution or a mild detergent specifically designed for outdoor use. Avoid using harsh chemicals that can discolor or degrade the decking.
Safety equipment: Wear protective gear such as goggles, gloves, and closed-toe shoes to shield yourself from debris and cleaning agents.
Broom or brush: Use a stiff-bristled broom or brush to loosen any stubborn dirt or debris before pressure washing.
Water source: Ensure you have access to a water source, such as an outdoor faucet, with enough pressure and volume to operate the pressure washer effectively.
Tarp or plastic sheeting: Lay down a tarp or plastic sheeting to protect surrounding areas or plants from overspray or cleaning solution runoff.

By gathering all the necessary equipment beforehand, you’ll be ready to tackle the job without interruptions and ensure a successful PVC deck cleaning.

Clearing the deck and surrounding areas

Before starting the pressure washing process, it is important to clear the deck and its surrounding areas to ensure a safe and effective cleaning session.

First, remove any furniture, plants, or decorative elements from the deck. This will not only give you more space to work but also protect them from potential damage caused by the pressure washer.

Next, sweep the deck to remove any loose debris such as leaves, twigs, or dirt. Use a broom or a leaf blower to make sure the surface is clean and ready for pressure washing.

It is also recommended to cover any electrical outlets, light fixtures, or other vulnerable areas with plastic or waterproof tape. This will prevent water from damaging these sensitive elements during the cleaning process.

In addition, take a moment to inspect the surrounding areas of the deck. If there are any delicate surfaces such as windows, glass doors, or delicate plants, consider covering them or protecting them with plastic sheets or drop cloths to avoid accidental damage.

By taking these simple steps to clear the deck and its surroundings, you will create a safe and well-prepared environment for the pressure washing process, ensuring the best possible results without any unnecessary damage.

Pressure Washing the PVC Decking

Cleaning your PVC decking regularly is essential to keep it looking its best. One effective method for deep cleaning is pressure washing. Pressure washing removes dirt, grime, and stains that can accumulate on the surface of your PVC decking over time.

1. Preparation

Before pressure washing your PVC decking, it’s important to prepare the area properly. Start by removing any furniture, plants, or other items from the deck. This will ensure that nothing gets damaged during the cleaning process. Next, sweep the deck to remove loose debris like leaves and dirt.

2. Choosing the Right Nozzle

When pressure washing your PVC decking, it’s crucial to select the right nozzle for the job. Using too much pressure can damage the surface, while using too little pressure may not effectively clean the decking. A medium-pressure nozzle is typically a good choice for PVC decking.

3. Testing a Small Area

Before pressure washing the entire PVC decking, it’s a good idea to test a small, inconspicuous area first. This will help you determine the appropriate pressure and distance to use for the best results. Adjust the pressure and distance accordingly based on the test results.

4. Pressure Washing Technique

When pressure washing your PVC decking, you should start at one end and work your way towards the other end systematically. Hold the nozzle at a distance of about 2 feet from the surface and maintain a steady, sweeping motion. Keeping the nozzle moving will help prevent any damage to the PVC decking.

5. Cleaning Solution

In some cases, using a mild cleaning solution may enhance the results of pressure washing. Before applying any cleaning solution, check the manufacturer’s instructions to ensure that it is safe for use on PVC decking. Apply the solution evenly, let it sit for a few minutes, and then pressure wash as usual.

6. Rinse Thoroughly

After pressure washing your PVC decking, it’s important to rinse the surface thoroughly. This will remove any remaining cleaning solution or debris. Use a hose or bucket of water to rinse the decking, starting from one end and working your way towards the other end.

By following these steps, you can effectively pressure wash your PVC decking and keep it looking clean and beautiful for years to come.

Setting the pressure washer to the correct settings

Before you start pressure washing your PVC decking, it’s important to set the pressure washer to the correct settings to avoid damaging the surface. Follow these steps to ensure you are using the appropriate pressure:

Step 1: Choose the right pressure washer

Ensure that you have a pressure washer that is suitable for cleaning PVC decking. Look for a pressure washer with a PSI (pounds per square inch) rating of 1500 to 2000. This will provide enough pressure to effectively clean the surface without causing any damage.

Step 2: Adjust the pressure

Most pressure washers come with an adjustable pressure setting. To clean PVC decking, it is recommended to set the pressure between 1200 and 1500 PSI. Lower pressure settings can be used for delicate areas or for areas with stubborn stains, while higher settings may be necessary for tougher stains and dirt.

Step 3: Test the pressure

Before you start pressure washing the entire decking, it’s a good idea to test the pressure on a small, inconspicuous area to ensure that it doesn’t cause any damage. Start with the lowest pressure setting and gradually increase it if needed. Keep an eye out for any signs of damage, such as splintering or discoloration.

Step 4: Use the correct nozzle

Choose a nozzle that provides a wide spray pattern, such as a 40-degree nozzle. This will distribute the pressure evenly and prevent any concentrated spots that may cause damage. Avoid using a narrow nozzle or a turbo nozzle, as they can be too powerful and lead to surface damage.

Step 5: Maintain a safe distance

When pressure washing PVC decking, it’s important to maintain a safe distance between the pressure washer and the surface. Hold the nozzle approximately 12-18 inches away from the decking to ensure that the pressure is evenly distributed and to minimize the risk of damage.

Note: Always read the manufacturer’s instructions for your specific pressure washer model and follow their recommendations on pressure settings and usage. If you are unsure, it’s best to consult a professional or contact the manufacturer for guidance.
