A well-maintained deck can be the centrepiece of your outdoor space, providing a beautiful area for relaxation, entertainment, and family gatherings. But, to keep it looking great and protect it from the elements, it’s essential to treat your decking regularly. Proper treatment can extend the life of your deck, enhance its natural beauty, and help prevent costly repairs down the road. Here’s a step-by-step guide to treating your decking so it can stand the test of time.
1. Start with a Thorough Cleaning
Before applying any treatment, make sure your decking is clean and free of debris. Here’s how:
- Clear the Surface: Remove furniture, planters, and any other items on your deck.
- Sweep Away Dirt: Use a broom to remove loose dirt, leaves, and debris.
- Wash the Deck: Use a pressure washer on a gentle setting or scrub with a deck-cleaning solution and a stiff brush. Be cautious with pressure washing; high pressure can damage softer wood.
- Remove Mildew and Algae: If you see green or dark spots, apply a deck cleaner specifically designed for mould or algae.
Allow the deck to dry thoroughly before moving on to the next step.
2. Sand the Surface (if needed)
For older or rough surfaces, sanding is a good option to create a smoother finish and ensure the treatment adheres well:
- Use the Right Grit: For softwoods, a medium grit (80-120) works well, while hardwoods may need a finer grit (120-150).
- Focus on Rough Spots: Sand down any splintered or rough areas.
- Remove Dust: After sanding, thoroughly sweep or vacuum the surface to remove all dust.
3. Choose the Right Treatment: Stain, Oil, or Sealant
Choosing the right treatment depends on your decking material, climate, and desired look. Here’s a breakdown of the options:
- Decking Oil: Oils penetrate the wood deeply, nourishing and protecting it from within. They enhance the wood’s natural colour and are ideal for weather resistance. Oils are especially suited for hardwoods and are great for regions with harsh weather.
- Wood Stain: A stain adds colour and provides UV protection, preventing your deck from fading. Choose a stain if you want to change the colour of your deck or add richness to its appearance. Stains typically provide a thin layer of protection on the surface.
- Sealant: Sealants create a water-resistant barrier on the surface of your deck, protecting it from rain and moisture. They’re suitable for areas with heavy rainfall or moisture exposure but may need to be reapplied more often.
Tip: Make sure the treatment you choose is specifically designed for outdoor decking, as it will offer better durability and UV resistance.
4. Apply the Treatment
Applying your chosen treatment correctly is essential for maximum protection:
- Use a Brush, Roller, or Sprayer: Brushes allow for more control, while rollers and sprayers can cover larger areas quickly. Ensure even application by working along the grain.
- Apply Thin, Even Layers: Start with a thin layer; thicker applications can result in sticky surfaces or uneven absorption.
- Follow Manufacturer’s Instructions: Every product is slightly different, so check drying times and recommended number of coats.
Allow ample drying time before applying a second coat or placing items back on the deck. Multiple coats may be necessary depending on the condition of your wood and the treatment you’ve chosen.
5. Perform Regular Maintenance
Regular care will keep your deck looking its best between treatments:
- Sweep and Clean: Frequently remove dirt and leaves, which can trap moisture and lead to mould or rot.
- Re-treat as Needed: Most decking benefits from a new treatment once a year, especially after winter or rainy seasons. Look for signs like fading, water absorption, or rough patches to determine if it’s time for reapplication.
- Cover or Store Furniture: During harsh weather or the off-season, consider covering or moving items to avoid moisture build-up.
Additional Tips for Deck Longevity
- Avoid High-Pressure Washing: Pressure washing on high settings can damage the wood. Use low pressure or a soft brush for routine cleaning.
- Mind the Weather: Don’t apply treatments when rain is expected or in extreme temperatures, as this can impact drying and absorption.
- Inspect for Repairs: Regularly check for loose boards, protruding nails, or signs of rot, and address any issues before they worsen.
By investing a little time and effort into treating and maintaining your decking, you’ll protect it from the elements and keep it looking beautiful year-round. Plus, you’ll be able to enjoy a safe and stunning outdoor space for many years to come!
