Exterior Oils
Choose Treatex Exterior Oils to achieve a premium finish for your outdoor wooden surface. Our Exterior Oil is ideal for adding the final touch to a range of home installations, including decking, wooden doors or cladding. Our water-repellent formula is designed to seep through timber surfaces, clinging to the wood capillaries and offering solid defence against the elements - all while preventing the development of cracks and swelling.
Treatex Exterior Oils also help to provide an effective weather resistant coating, where our formula is both waterproof and protective against UV light. Our impressive colour range includes a multitude of shades including champagne, bay and buckskin, so you’re guaranteed to find the perfect match for your space.
Features
Easy to apply
UV resistant (excluding Clear)
Highly water resistant
Contains no biocides or preservatives
Safe for use on children's toys
Can be finished with Treatex Anti Slip Decking Oil or Treatex UV Oil
Sheer is a lightly tinted clear finish with UV inhibitors
Exterior Oil colours can be overcoated with Exterior Oils Clear for extra wear protection
‘Clear’ is not a UV protective finish and timbers treated only with Clear will break down and bleach in sunlight much quicker than any of the other options in the range. Clear should only be used to overcoat one of the colour options in the Exterior Oils range. For a near clear finish with UV protection, please use ‘Sheer’ or for the best protection, use one of our more pigmented options.

Prep/Application
Preparation
This product works best on unfinished timber. Exotic and pressure treated timbers should be allowed to weather for approximately 3 months before finishing. Previously porous finishes should be thoroughly cleaned or lightly sanded with all flaking and peeling removed before application. Ensure the surface is dry and free from any contaminants. Make sure you buy sufficient product to complete the whole project and mix multiple tins together before use to achieve the same finish.
If you find decay, mould or fungi, this should be treated first with Treatex Preservative. Exterior timbers with high tannin levels should be treated with Treatex Stain Inhibitor. Timber must have a moisture content below 18% and the temperature should be between 8 and 24 degrees celsius during application and drying.
Application
Make sure the tin/tins are stirred thoroughly before and during use.
Use a brush or roller to evenly apply the Treatex Exterior Oils, moving in the same direction as the wood grain. If possible apply the first coat to all sides of the wood before installation, paying particular attention to any end grain. Apply liberally on the end grain to fully seal.
After 12 hours of drying, a second coat can be applied. After this coat, leave for approximately 12-24 hours to dry. Don’t apply too thickly.
For decking, we recommend applying Treatex Anti-Slip decking oil.
