When it comes to maintaining the appearance and longevity of your outdoor spaces, few things are as effective as pressure washing. Decks and patios, in particular, endure a lot of wear and tear from the elements, foot traffic, and the accumulation of dirt, algae, and grime. Pressure washing is a fast, efficient way to keep these surfaces looking their best while protecting them from damage. In this guide, we’ll cover everything you need to know about pressure washing for decks and patios.
Why Pressure Washing Is Important for Decks and Patios
Both decks and patios are exposed to harsh outdoor conditions, including sun, rain, wind, and dirt. Over time, this exposure can lead to a buildup of dirt, mildew, and algae, which not only dulls the appearance of your outdoor space but can also make surfaces slippery and unsafe.
By pressure washing your deck or patio regularly, you can:
- Enhance Appearance: Pressure washing restores the original look of your wood or stone surface, making it look clean, fresh, and inviting.
- Prevent Damage: Dirt and grime can cause long-term damage if not removed. Algae, for example, can degrade wooden decks and cause cracks in stone patios.
- Improve Safety: Pressure washing removes algae, moss, and other slippery substances, reducing the risk of slips and falls.
- Prepare for Sealing or Staining: If you’re planning to reseal or stain your deck, pressure washing is an essential first step to ensure proper adhesion.
How Often Should You Pressure Wash Decks and Patios?
For most homeowners, a once-a-year pressure washing is sufficient to keep decks and patios looking their best. However, if your outdoor area is heavily used, exposed to a lot of shade, or near a garden where dirt is frequently tracked, you may need to pressure wash more often. The best time to pressure wash is typically in the spring, right after the rainy season and before you begin outdoor entertaining.
Pressure Washing Tips for Decks
Wooden decks require special care when pressure washing, as the high-pressure spray can easily damage the wood if not used correctly. Here’s how to do it safely:
- Choose the Right Pressure Setting: Wood is a soft material compared to stone or concrete, so use a lower pressure setting, usually around 500 to 600 psi (pounds per square inch).
- Use a Fan Tip Nozzle: A fan tip distributes the water in a wider spray, preventing damage to the wood. Keep the nozzle at least 30 cm away from the surface.
- Test a Small Area First: Before cleaning the entire deck, test the pressure on a small, hidden section to ensure you won’t damage the wood.
- Wash Along the Grain: Move the pressure washer in long, even strokes, following the grain of the wood to avoid splintering.
- Consider Using a Cleaning Solution: For stubborn stains or algae, use a wood-safe detergent before pressure washing to break down the grime.
Pressure Washing Tips for Patios
Patios, usually made of stone, concrete, or pavers, can handle more pressure than wooden decks, but they still need careful handling to avoid damage:
- Use a Medium Pressure Setting: Stone and concrete can typically handle pressures between 1500 and 2500 psi, depending on how dirty the surface is.
- Use a Rotary or Turbo Nozzle: For deeper cleaning of stone or concrete, a rotary nozzle helps break up tough stains without damaging the surface.
- Pre-Treat Stains: If your patio has oil stains, rust, or mildew, use a concrete cleaner or a specialised patio cleaner to pre-treat the area before pressure washing.
- Rinse Thoroughly: After cleaning, be sure to rinse the patio thoroughly to remove all detergent residues, which can leave streaks or discolouration.
When to Call in the Professionals
While DIY pressure washing can be a great way to maintain your outdoor space, some situations call for the help of a professional. If your deck or patio has deep-set stains, significant wear, or you’re concerned about damaging the surface, hiring a professional service can save you time, effort, and potential repair costs.
