Drying time: approx. 3-6 hours dependent on climatic conditions, drying times can be decreased by increasing temperature introducing air flow to the applied area.

Uses: Suitable for use on: Claddings, doors, windows. shingles and other exterior joinery - not suitable for decking or other walkways - horizontal timbers may wear sooner.  compatible with 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. 

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 ambient temperature must be between 8oc and 25oc during application and drying. 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.


Insider 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
