Behr Penetrating Oil – Long-Lasting Deck Protection
May 27, 2025 in Property Managers & Landlords
At Oxford County Handy People, we recommend Behr Penetrating Oil for customers who want deeper protection, longer-lasting results, and a beautiful deck for decades.
Unlike surface coatings, this oil soaks into the wood fibres, preserving the structure from the inside out.
🔧 Why We Use Penetrating Oil
✅ 1. Protects Against Rot, Splitting, and Warping
Wood left untreated can begin to split, cup, or rot in just 5–8 years, especially in Canada’s wet and cold climate. Penetrating oil locks out moisture and helps the wood expand and contract naturally with seasonal changes.
✅ 2. Preserves Colour and Texture
UV rays and water exposure cause decks to turn gray and rough over time. Regular oiling keeps the grain sharp, the surface smooth, and the natural tones rich — no heavy sanding needed.
✅ 3. Nourishes the Wood
Penetrating oil doesn’t just coat — it feeds the wood, helping prevent internal drying and long-term cracking.
🧼 Maintenance That Pays Off
We recommend reapplying every 1.5 to 2 years, depending on sun exposure and usage.
| Maintenance Cycle | Deck Lifespan | Notes |
|---|---|---|
| No sealing or oil | 5–8 years | Grays quickly, rots in shaded areas |
| Oiled every 3–4 years | 10–15 years | Better than nothing, but sanding is needed |
| Oiled every 1.5–2 years | 15–25 years | Long life, smooth surface, clean look |
🔁 Think of Oiling Like Dental Cleaning
Just like skipping the dentist leads to bigger bills later, skipping oiling leads to:
Gray wood and water damage
Worn seal and flaking in just one season
More prep time and $1–2 per square foot in extra labour down the road
💡 Bottom Line
If your goal is to protect your investment and avoid costly deck repairs or full replacement:
Stick to a 1.5–2 year cycle
Choose penetrating oil for long-term value
Enjoy a rich finish that looks almost new for years to come
