Outdoor spaces like our decks are the heart of summer gatherings, a perfect spot for morning coffee, and a marvellous extension of our homes. Yet, with its brutal winters and often humid summers, our city's unique climate can take a heavy toll on these wooden sanctuaries.

With time, decks usually become covered with dirt, grime, and mould, losing their original charm. They can also become slippery hazards for individuals stepping on them. If you are also noticing your deck looking a bit dull or perhaps have been admiring how clean and vibrant your neighbours’ deck looks compared to yours, it is time to consider transforming your deck using pressure washing.

In this blog, we have discussed how to effectively pressure wash your deck to ensure it remains a safe outdoor retreat for seasons to come.

5 Reasons to Pressure Wash Your Deck

Pressure washing your deck doesn't only make it look neat. But it's a vital maintenance task that offers many benefits for your outdoor living space. Some of the benefits of pressure washing your deck are as follows:

Restoring Aesthetics

You can get the most immediate and satisfying result by pressure washing your deck. Pressure washing helps get rid of years of accumulated dirt, discolouration, mould, mildew, and grime, revealing the wood's original colour and charm. Your deck will look revitalised and almost new, giving it an absolute aesthetic vibe.

Increasing the Lifespan of the Deck

Organic growths like mould and mildew don't just look unsightly; they actively contribute to the decay and rot of your deck boards. Once you remove them, pressure washing helps prevent moisture retention while stopping the degradation process, significantly extending the lifespan of your deck.

Preparing for Colouring or Sealing

Pressure washing is essential if you plan to colour or seal your deck. It creates a clean surface that allows colours and sealers to penetrate properly, ensuring a durable finish that protects the wood. Without pressure washing, your chosen sealing will not look very appealing.

Enhancing Safety

Algae and mildew growth can make a deck incredibly slippery, especially when wet. Using a pressure washing procedure can eliminate these hazardous growths, making your deck a much safer place for family and friends to enjoy, with zero risks of slips and falls.

Improving Hygiene

Mould and mildew can contribute to poor outdoor air quality and trigger allergies. Pressure washing can remove these harmful growths and provide a healthier environment around your home. It will also be helpful for those with respiratory sensitivities.

The 3-Step Pressure Washing Process

Once you have all the necessary tools to pressure wash your deck, you are ready to bring your deck back to life. Here's a three-step deck-washing process that makes your deck neater!

Apply Cleaning Solution

You need to attach the soap nozzle to your pressure washer. If your machine has a detergent tank, fill it with your chosen deck cleaning solution.

Begin by applying the soapy solution across a small section of your deck. You need to start working from one end to the other. Ensure the deck surface is thoroughly saturated. Now, allow the cleaning solution to stay for the time recommended by the product manufacturer, which is usually between 10 and 20 minutes.

Remember not to let the solution dry on the deck, as this can leave unsightly stains. If it starts to dry, lightly mist it with water.

Pressure Wash the Deck

Now, you need to switch to the washing nozzle to start pressure washing the deck. Start with the nozzle approximately 6-12 inches away from the deck surface. The closer you hold the wand, the higher the pressure. Hold the wand at a slight angle, around 45 degrees, to the deck surface, moving in long, consistent, overlapping strokes.

Work from one end of a single board to the other, maintaining a steady pace. Avoid staying in one spot longer, as this can cause etching or gouging.

Always work your way from the part of the deck nearest to your house outwards and from the highest point downwards, allowing dirty water to flow away.

Rinse Thoroughly

Once you have cleaned a section, rinse it properly to remove all traces of the cleaning solution and loosen dirt. You can continue to use the nozzle for rinsing, or if you prefer a gentler approach, switch to a standard garden hose with a spray nozzle.

Ensure all residue is washed away. Double-check for any overspray on your house siding, plants, or windows, and rinse them thoroughly.

Post-Pressure Washing for Better Results

Once the pressure washing is complete, the work isn't quite over. Proper drying and sealing are crucial for protecting your deck and maximising its lifespan, especially given Winnipeg's weather patterns.

• Allow to Dry Completely: Before applying any stain or sealer, this step is essential. Depending on the weather conditions in Winnipeg, your deck will need to dry for at least 24-48 hours, sometimes even longer. The wood must be completely dry to the touch, or else the stain/sealer will not penetrate or adhere properly, leading to peeling or an uneven finish. Aim for a wood moisture content below 15% if you have a moisture meter.
  

• Inspect the Deck: Once dry, take a moment to inspect your deck closely. Look for any areas you might have missed or spots where stubborn grime remains. These can often be touched up with a careful, brief re-application of the pressure washer. Also, check for any raised wood fibres or splintering that might have occurred during the wash, and lightly sand these areas smooth.
  

• Apply Sealer or Stain: For wooden decks in Winnipeg, applying a good-quality sealer or stain is vital for protection against moisture, UV damage, mould, and the freeze-thaw cycles. Choose a product that is clear, semi-transparent, or solid colour to suit your aesthetic preference and offers excellent protection. Follow the manufacturer's instructions precisely for application, paying attention to temperature guidelines and coverage rates. This final layer will protect your investment and keep your deck looking fantastic for years to come.
