SPONSOR | SOFTWOOD TRADER OF THE YEAR
Koppers
treated timber exposes the end grain – the point where wood is most porous, and where moisture, decay fungi, and insect attack are most likely to take hold. Left untreated, these exposed areas can compromise the structural integrity, appearance, and lifespan of even the highest-quality timber. That’s why Koppers developed PROTIM®
W WB7 — a high-performance,
water-based end coat formulated to seal and protect timber’s most exposed surfaces.
Precision protection for exposed timber PROTIM WB7 is designed to work in harmony with preservative-treated timber. By soaking into the end grain, it forms a durable barrier that restores the protective envelope created during the pressure treatment process. Whether applied immediately after cutting or to existing structures requiring a maintenance coat, it enhances durability and helps maintain aesthetic consistency. This added layer of defence ensures timber performs as intended, extending its service life and helping reduce maintenance or costly replacements. The end grain of timber behaves differently from the rest of the board. It’s more absorbent, more vulnerable, and more exposed to weathering and fungal ingress. Even the best industrial treatments can’t fully protect freshly exposed timber once it’s cut or drilled on-site. Applying PROTIM WB7 at these critical points helps: • Prevent moisture ingress and preservative leaching

hether you’re building a deck, fence, or cladding system, one truth holds: timber’s greatest vulnerability lies at the ends. Every cut, notch, or borehole made on

• Maintain warranty compliance • Reduce the risk of premature decay • Improve the consistency of colour and finish
Simple to apply, built to last PROTIM WB7 is water-based, low odour, and fast-drying — making it ideal for use on-site without the need for specialist equipment. Whether applied by brush, dip, or spray, it provides instant, visible protection to notches, cuts, boreholes and cross-cuts. Available in Green, Brown, and Clear options, it
complements the appearance of treated timber without compromising protection. It’s an ideal choice for timber used in: • Decking and balustrades • Fencing and gates • Garden furniture • Cladding and structural timbers
A small step that makes a big difference End-grain protection is often overlooked — but it’s a small, cost-effective step that can make a significant difference to timber performance over time. Tradespeople, specifiers and contractors who use PROTIM WB7 demonstrate care and quality in their craftsmanship, helping projects stand the test of time. ■
