Walther Strong HD Timber Coating

Protect timber from moisture ingress, ground rot, and UV degradation with Walther Strong Heavy Duty Timber Coating. Formulated for high-exposure outdoor applications, this trade-grade coating forms a durable, water-repellent barrier over fence posts, gravel boards, retaining wall sleepers, and cut timber ends. Its deep-penetrating formula bonds directly to wood fibers to prevent splitting, checking, and fungal decay, especially in critical ground-contact zones. Available in convenient 1L tins for end-grain touching up and 4L tubs for large-scale timber treatment.
