Can You Pressure Wash Composite Decking?
One of the most common questions asked is whether or not it is safe to pressure wash composite decking. Following are the benefits and risks of pressure washing composite decking, as well as provide tips for safely and effectively cleaning your composite deck.
Pros of pressure washing composite decking
Pressure washing composite decking can have several benefits, including:
- Efficient cleaning: Pressure washing can quickly and effectively remove dirt, grime, and other debris from the surface of composite decking.
- Cost-effective: Compared to hiring a professional cleaning service, investing in a pressure washer can save you money in the long run.
- Saves time: Cleaning a large area of composite decking can be a time-consuming task. Pressure washing can significantly reduce the time and effort required.
- Environmentally friendly: Pressure washing uses less water than traditional cleaning methods, making it a more eco-friendly option.
- Preserves the deck’s lifespan: Regular pressure washing can help remove buildup that could cause long-term damage to the deck’s surface, potentially extending its lifespan.
Cons of pressure washing composite decking
While pressure washing may seem like a quick and efficient way to clean your composite decking, there are some potential downsides to consider. One of the main concerns is that the high pressure of the water can damage the surface of the decking, causing scratches or even removing the protective layer.
Furthermore, pressure washing can sometimes push water deep into the composite material, leading to mold or mildew growth that can be difficult to remove. Lastly, if you are not careful, pressure washing can also lead to uneven cleaning, with some areas of the deck appearing cleaner than others.
To avoid these issues, it’s best to use a gentle cleaning solution and a soft-bristled brush to clean your composite decking.
Types of composite decking that can be pressure washed
Composite decking is a popular choice for homeowners due to its low maintenance requirements and durability. While pressure washing can be an effective way to clean composite decking, not all types of composite decking can withstand the pressure. The following types of composite decking can be pressure washed:
- Capped composite decking: Capped composite decking has a protective outer layer that can withstand the pressure from a pressure washer.
- PVC decking: PVC decking is made from 100% plastic and can withstand the pressure from a pressure washer.
Note that while pressure washing can be effective, it should be done with caution to avoid damaging the decking. Using the wrong pressure setting or nozzle can cause damage, follow the manufacturer’s guidelines and recommendations.
How to Pressure Wash Composite Decking
Here is the step-by-step process to pressure wash composite decking.
Equipment needed for pressure washing
Pressure washing composite decking requires specific equipment to ensure a thorough and effective cleaning. The following tools are essential for pressure washing composite decking:
- Pressure washer: Choose a pressure washer with a PSI (pounds per square inch) of 1,500 to 2,000 and a GPM (gallons per minute) of 1.4 to 1.6. This will provide enough power to remove dirt and grime without damaging the composite material.
- Nozzle: Use a 25-degree fan tip nozzle for pressure washing composite decking. This nozzle will provide a wider spray pattern that is ideal for cleaning large areas.
- Cleaning solution: Use a cleaning solution specifically designed for composite decking. This will help remove stubborn stains and keep the surface looking new.
- Safety gear: Wear protective gear, such as goggles, gloves, and closed-toe shoes, to prevent injuries while pressure washing.
By using the right equipment, you can safely and effectively pressure wash your composite decking, restoring it to its original beauty.
Preparation before pressure washing
Before pressure washing composite decking, prepare the surface properly to avoid any damage. This includes clearing the area of debris and loose dirt, inspecting the decking for any damage or cracks, and selecting the appropriate pressure washing equipment and cleaning solution.
Also, take safety precautions such as wearing protective gear and testing the pressure washer on a small area before beginning the full cleaning process. By properly preparing the decking and taking necessary precautions, pressure washing can be an effective method for cleaning and maintaining composite decking.
Pressure washing technique for composite decking
To pressure wash composite decking, follow a specific technique to avoid damaging the material. First, make sure to use a pressure washer with a maximum pressure of 3,000 psi and a fan tip nozzle to distribute the water evenly. Before starting, remove any debris and furniture from the deck and cover any nearby plants or surfaces with plastic sheeting.
Begin by spraying the deck with water to remove loose dirt and debris, then apply a composite deck cleaner and let it sit for a few minutes. Use the pressure washer to rinse off the cleaner and dirt, working in sections to ensure even cleaning.
Avoid using hot water, a concentrated nozzle, or getting too close to the surface, as this can cause damage to the material. Allow the deck to dry completely before using it again.
Safety tips when pressure washing
When pressure washing composite decking, it’s important to prioritize safety to avoid accidents or damage to the deck.
Some safety tips to keep in mind include wearing protective gear such as eye goggles and closed-toe shoes, testing the pressure washer on a small area first, using the appropriate nozzle and pressure setting, and avoiding aiming the pressure washer directly at people, pets, or plants. Be mindful of electrical hazards and keep the pressure washer away from electrical outlets or cords.
By following these safety tips, you can effectively clean your composite decking without any mishaps.
