FAQ
Why is it important to use a timber preservative for cut ends?
Cutting or drilling timber exposes untreated wood that is vulnerable to moisture, fungi, and insect attack. Using a timber preservative for cut ends seals these exposed areas, maintaining the timber’s durability and warranty protection. Without resealing, the timber’s lifespan and performance can be significantly reduced.
Can XJ Timber Preservative be used on all types of outdoor timber?
XJ is ideal for resealing cut ends of LOSP treated pine, blue pine, and other non-durable timbers like Oregon and Meranti. It is suitable for all above-ground outdoor timber applications where protection from decay and insects is needed. Always apply to dry, clean surfaces for best results.
How often should I reapply XJ Timber Preservative on cut ends?
Reapplication depends on exposure and weather conditions but is generally recommended in high hazard or heavily weathered situations. Check timber regularly and reapply if the cut ends appear dry or unprotected. Following label guidance ensures ongoing protection.
XJ Timber Preservative is the trusted timber preservative for cut ends that helps maintain the strength and durability of your outdoor timber projects. By resealing exposed surfaces, it ensures your timber resists decay, borers, and termites for years to come. Use XJ to protect window frames, doors, fences, and more with confidence.

Q & A
XJ Timber Preservative
Hey Graham,
Do not use XJ Timber Preservative on a beehive box. This product contains Permethrin, which is an insecticide, and will kill the bees.
Hey Nick,
XJ Timber Preservative is an oil-based product so an oil-based paint is recommended however, you will need to make sure the solvent has flashed off before applying any paint. It’s also a good idea, as in most cases, to apply paint to a small out of the way section first. For more tailored advice, I would recommend speaking with a paint expert on this one first if you have a large job to do.
