Treatex Exterior Oils work best on unfinished timbers. Exotic and pressure treated timbers should be allowed to weather for approximately 3 months before finishing. Previous finishes which stop Exterior Oils 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 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. Timbers susceptible to mould and fungi should be treated first with a suitable preservative. We advise that when using Exterior Oils, 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.
Stir tins thoroughly, before and during use. Use a brush, roller or spray to evenly apply Treatex Exterior Oils in the same direction as the wood grain. Pay particular attention to the end grain, where you should apply liberally. After approximately 12 hours the first coat can be overcoated. Apply with a brush or roller a second coat of Exterior Oils.After the second coat leave for approximately 12 hours to dry. A third coat can be applied if necessary. Finishing with Exterior Oils Clear will add further protection against wear and abrasion. For decking, we recommend applying Treatex Anti-slip Decking Oil. Treatex Exterior Oils are not a surface building product, please don’t apply too thickly!
