UV Oil
Being exposed to the elements all year round, our outdoor wood surfaces go through a lot. In particular, the effects of sun bleaching can completely ruin the appearance of wood, and can even warp it in some cases. Fortunately, Treatex UV Oil acts as a reliable shield against harsh UV rays. Made from a combination of natural, refined oils, our expert formula is effective at penetrating into even the most dense types of timber, providing a strong, long-lasting defence.
Alongside its durable properties, Treatex UV Oil has a clear finish, allowing you to make the most of your timber’s natural beauty. It’s also highly water-resistant, so you can count on it to protect your wood come rain or shine. This UV wood protection product is suitable for most vertical timber applications, including fencing, doors, windows and other outdoor structures. Please note that because of the use of sustainably sourced natural oils, Treatex UV Oil is not suitable for horizontal surfaces.

Best applied with a brush or roller
Protects the timber from water ingress and silvering
Product Specs
Usage/coverage
Suitable for: internal and external use
Recommended timbers: Suitable for use on most timbers - please check if unsure. Timbers with a high tannin content such as air dried Oak may still leach tannin in the early stages.
Applications: Cladding, doors, windows. shingles and other exterior joinery - not suitable for decking or other walkways
1L will cover approximately 25m² in one coat depending on timber and method of application (rough sawn/planed may consume more)
2.5L will cover approximately 50m² in one coat depending on timber and method of application (rough sawn/planed may consume more)
Preparation/Application
Preparation
Treatex UV Oil works best on unfinished timbers. Previous finishes which stop UV Oil penetrating into the timbers (e.g. paints and other ‘closed’ finishes) must be fully removed prior to application. Previous porous finishes should be lightly sanded to 120 grit before over coating. When over coating a previously finished surface, a trial application is essential. Flaking or peeling finishes must be fully removed prior to application. Ensure the timber is dry and free from possible contaminates e.g. algae, grease, dirt, dust etc.
We advise that when using Treatex UV Oil, sufficient product is purchased to complete the whole project and when more than one tin is required it is advisable to mix them together before use. The timber must have a moisture content below 18% and the timber must have a moisture content around 18% or lower and the ambient temperature must be between 8c and 25c during application and drying. Ensure that no rain is forecast before, during or after application or that timber is treated in a dry environment. We strongly recommend a trial application prior to starting the project.
Application
Stir tins thoroughly, before and during use. Use a brush or roller to evenly apply Treatex UV Oil in the same direction as the wood grain. Pay particular attention to the end grain, where you should apply liberally. If possible, coat all sides of the timber at least once. After approximately 12 hours the first coat can be overcoated. Apply with a brush or roller a second coat of Treatex UV Oil, and leave for approximately 12-24 hours to fully dry. A third coat can be applied for further longevity but is not necessary.
Tips
Treatex brushes and rollers are available. Wet brushes and rollers can be cleaned with Treatex Thinner or white spirit.
Store tins in a cool and frost free environment. Unopened tins will last for five years. Once tins are opened, transfer contents to a smaller airtight container. Treatex UV Oil can be used as a protective top coat of applications of Treatex Exterior Oils and Classic Colours
