UV Oil

Treatex UV Oil is a clear, exterior wood finish that offers high-level protection against UV rays and weathering. Formulated with natural oils, it penetrates deeply into the timber, which preserves its natural appearance while providing a water-resistant barrier. Ideal for cladding, doors, and windows, it prevents greying and maintains the wood's integrity over time. Easy to apply and maintain, Treatex UV Oil is a reliable solution for safeguarding your exterior wooded surfaces.

Preparation/Application

Preparation

Treatex UV Oil works best on unfinished timbers, as previous finishes will stop the UV oil from penetrating the timbers properly. So previous finishes should be lightly sanded and removed before any application. Ensure the timber is dry and clean, removing dirt, grease, algae and any other contaminants.

Mix multiple tins together for large jobs and ensure you have enough product before starting the project. We recommend a trial application before starting the full project. The timber must have a moisture content below 18% and the ambient temperature should be between 8 and 25 degrees celsius during application and drying.

Application

  1. Stir cans thoroughly beforehand and during use.

  2. Apply Treatex UV OIl using a brush and roller, ensuring you are moving in the same direction as the wood grain. Apply liberally to the end grain and coat all sides at least once.

  3. Leave for 12 hours, then apply another coat of UV wood protection. Leave this for 12-14 hours to fully dry.

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

External Oak Protection

While our External Oak Protection was highly successful, it was limited to treating timbers such as Oak or Idigbo. Our UV Oil replaces the External Oak Protection as it is a more diverse product, providing a clear, UV resistant and weatherproof finish to most timbers.

You can use it to treat external oak surfaces, softwoods and hardwoods. You can also use it to apply a clear finish or change colour.
