Radial Timber Sealer | Clear Oil Sealer for Natural Weathering
The professional solution for stabilising timber while achieving a natural silver-grey aesthetic.
Radial Timber Sealer is a high-performance, Australian Made clear oil sealer. Unlike pigmented oils that mask the ageing process, Radial Timber Sealer is designed to help your timber age gracefully. It provides essential moisture control to minimise checking, splitting, and cupping, while allowing the sun to naturally weather the timber into a beautiful, uniform silver-grey.
Why Choose Radial Timber Sealer?
- Natural Silver-Grey Look: Contains no UV absorbers or pigments. It is the perfect standalone product for achieving a fashionable “grey patina” without the structural damage of unprotected wood.
- Essential Moisture Protection: Controls the rate at which timber dries. This reduces the internal stresses that lead to dimensional instability, such as cupping and surface splitting.
- Machine Compatible: Formulated for high-efficiency application; it can be used in commercial coating machines for pre-oiled timber projects.
- Inbuilt Mouldicide: Treated with high-strength mouldicides to prevent the “black spotting” and fungal discolouration that occurs when timber is left entirely untreated.
- Designed for Green Timber: Originally engineered to help green timber season gracefully in situ. It is the ideal choice for Radial Timber board and batten cladding or natural edge weatherboards, allowing them to stabilise while they air-dry after installation.

Frequently Asked Questions
- Can I change my mind and add colour later?
Yes. Radial Timber Sealer is fully compatible with our pigmented range. If you decide you want a different look soon after application or even years down the track, you can over-coat it with Aussie Clear, Aussie Clear Light, or Walnut Timber Finish. - How do I prepare the timber if I want to switch to a pigmented finish?
If the timber has already started to weather, you must use Grey Deck Cleaner first. This strips away the greyed fibres and ensures the new pigmented oil can bond deeply with the fresh wood for a stunning result. - Does this sealer stop timber from turning grey?
No. Radial Timber Sealer is intentionally unpigmented to allow timber to weather to a natural silver-grey while protecting it from splitting and mould. - How well does Radial Timber weather over time?
Radial Timber Sealer allows for a very consistent transition to grey. The photo below demonstrates the natural weathering process occurring from top to bottom in 6-month intervals, reaching a full silver-grey at 18 months.
