PROTECTING FENCING TIMBER WHERE IT MATTERS MOST

A small step that makes a big difference to timber performance.

Every fencing contractor knows that timber’s biggest weakness isn’t on the surface — it’s at the ends. Every time a post, rail, or gate board is cut or drilled, the protective envelope created during pressure treatment is broken, exposing the end grain to moisture, decay fungi, and insect attack.

Left untreated, these vulnerable points can quickly lead to premature failure, discolouration, or costly replacements — even in the best pressure-treated timber.

That’s why Koppers developed PROTIM® WB7, a high-performance, water-based end coat that seals and protects exposed timber ends, helping fencing timber perform exactly as it should.

Seal, Protect, and Preserve
PROTIM WB7 works in harmony with factory-treated timber. It soaks into the exposed end grain to re-establish the protective barrier applied during treatment, preventing water ingress and maintaining long-term performance.

Quick to apply and fast-drying, it provides instant, visible protection on-site — ideal for fencing installers, farmers, and landscapers who need reliable performance without downtime.

Benefits include:
• Prevents moisture ingress and decay
• Maintains warranty compliance
• Improves consistency of colour and finish
• Extends service life and reduces call-backs

Built for Fencing Professionals
Designed for practical use in the yard or on-site, PROTIM WB7 is low odour, water-based, and easy to apply by brush, dip, or spray.

Available in Green, Brown, and Clear finishes, it complements the look of treated timber, giving a clean, professional result every time.

Ideal for:
• Fence posts and rails
• Gate frames and feather-edge boards
• Agricultural, domestic, and commercial fencing projects

Small Effort, Big Results
End-grain sealing is often overlooked, yet it’s one of the most cost-effective ways to extend the life of fencing timber. Contractors who use PROTIM WB7 not only protect their materials — they protect their reputation.

End-grain protection might seem minor, but it’s the difference between a fence that lasts a few seasons and one that stands the test of time.
