Best Oil for Cedarwood – Long-Lasting Protection with Osmo 420 UV Extra
Cedarwood is a premium material widely used for outdoor cladding, garden furniture, fencing, and architectural features due to its natural beauty, durability, and resistance to decay. However, even cedar needs protection to maintain its appearance and structural integrity over time. If you're searching for the best oil for cedar wood cladding or outdoor cedar furniture, look no further than Osmo 420 UV Extra Protection Oil Clear Satin.
Why Cedarwood Needs Protection
Cedar contains natural oils that make it more weather-resistant than other softwoods, but exposure to sun and moisture will eventually cause fading, greying, and surface damage. Without proper treatment, your cedar cladding or furniture can lose its rich colour and smooth texture.
This is why choosing the best oil for cedarwood is essential—not just for appearance, but for long-term performance.
What Makes Osmo UV Protection Oil Extra 420 Ideal for Cedar
Osmo 420 UV Extra is a clear, satin-matt exterior wood oil that offers exceptional UV protection while preserving the natural look of cedar. Here's what makes it stand out:
✔️ UV Protection for Outdoor Cedar
One of the most critical features for cedarwood oil finishes is UV resistance. Osmo 420 offers a UV protection factor of 12 (compared to untreated wood) when applied in two coats, significantly delaying the greying process caused by sun exposure.
✔️ Microporous & Weather-Resistant
This oil is microporous, meaning it allows the wood to breathe while repelling water. It won’t crack, peel, or blister over time, making it the perfect oil for cedar cladding, garden furniture, and outdoor cedar structures exposed to the elements.
✔️ Active Mould and Algae Resistance
Cedar can be prone to mould, algae, and fungal attack in damp environments. Osmo 420 is enhanced with active ingredients to protect against these threats—ideal for coastal or shaded properties.

How to Apply Osmo 420 on Cedarwood
To get the best results, follow these key steps when applying Osmo 420 on your cedar wood surface:
-
Surface Preparation: Ensure the cedar is clean, dry, and sanded no finer than P120 grit. Let fresh cedar weather naturally for a few weeks to enhance absorbency.
-
Base Coat (Optional): For improved UV protection and colour tone, apply a coloured base coat such as Osmo Natural Oil Woodstain before using Osmo 420.
-
Application: Use a flat brush or microfiber roller to apply two thin coats along the grain. Allow 12 hours drying time between coats.
-
Maintenance: Recoat every 2–4 years, or when signs of wear appear. No sanding is needed for reapplication—just clean and apply one thin coat.
