Applying decking oil is a straightforward process essential for protecting and enhancing the look of your wooden deck. It involves preparation, careful application, and allowing adequate drying time.
Here is a breakdown of how to apply decking oil effectively:
1. Prepare the Deck Surface
Before applying any oil, the deck must be properly prepared. This is crucial for ensuring the oil penetrates the wood evenly and achieves a lasting finish.
- Clean Thoroughly: Sweep away debris, leaves, and dirt. Use a dedicated deck cleaner and a stiff brush to remove grime, mildew, and old finishes. Rinse the deck completely with water.
- Allow to Dry: The wood must be completely dry before applying oil. Check the product instructions for recommended drying times, but typically this can take 24-48 hours depending on weather conditions.
- Sand (If Necessary): If the deck surface is rough or has stubborn stains or old peeling finishes, a light sanding may be required. Sweep or vacuum away all sanding dust.
- Check the Weather: Ensure no rain is forecast for at least 24-48 hours after application. Avoid applying in direct hot sun, which can cause the oil to dry too quickly and unevenly.
2. Apply the Decking Oil
Once the deck is clean and dry, you can begin applying the oil.
- Shake the Oil: Start by giving the oil a good shake to ensure pigments and binders are well mixed.
- Pour Out Oil: Pour it out into a suitable container or paint tray. Using a container can help manage the amount of oil applied.
- Choose Your Applicator: While rollers or pads can be used, the video reference notes that to save time, you'll want to use a large paint brush. A brush allows for good control and working the oil into the wood grain.
- Work in Sections: To avoid overlap marks, focus on three to four boards at a time. This allows you to maintain a wet edge and blend sections seamlessly.
- Apply Thinly and Evenly: Apply the oil along the length of the boards, following the wood grain. Apply a thin, even coat, ensuring complete coverage without allowing the oil to pool or puddle.
- Wipe Excess: After a short period (check product instructions, usually 15-30 minutes), wipe away any excess oil that hasn't soaked into the wood using a clean, lint-free cloth. This prevents sticky patches.
3. Drying and Second Coat
Allow the first coat to dry according to the manufacturer's instructions. Drying times vary significantly based on the product and weather conditions.
- Test Dryness: Test a small, inconspicuous area to ensure it's dry before walking on it or applying a second coat.
- Apply Second Coat (If Needed): Many decking oils recommend a second coat for enhanced durability and colour depth. Apply the second coat following the same method as the first, focusing on thin, even coverage and wiping excess.
- Final Drying: Allow the deck to dry completely before replacing furniture or heavy items.
Key Application Tips
- Always work along the length of the boards.
- Maintain a wet edge when working in sections to avoid visible lines.
- Don't apply too much oil at once; multiple thin coats are better than one thick coat.
- Always follow the specific instructions on your decking oil product tin.
Following these steps, including shaking the oil, pouring it out, using a large brush, and focusing on 3-4 boards at a time to prevent overlap marks, will help you achieve a well-protected and beautiful deck finish.
