An innovative solution for protecting timber details against moisture and rot, particularly in areas that are challenging to tape. This rubberised waterproof liquid is designed for ease of use, requiring only a brush or roller for application, with no need for specialist tools.

It effectively seals timber with a single coat, providing a durable moisture barrier that extends the life of wood structures. Ideal for treating end grains, cut ends, posts, stair stringers, and ledger boards, this coating is versatile and efficient, ensuring that even the most vulnerable timber components receive reliable protection against the elements. Paired with Walther Strong Deck Tape, HD Timber Coating forms a robust timber protection system, addressing both taped and untaped areas with equal efficacy. Its quick drying formula, capable of becoming touch dry in just 20 minutes under optimal conditions, makes it an excellent choice for both professionals and DIY enthusiasts. Each 4kg container covers around 150m of timber, offering extensive coverage and exceptional value. The low-VOC composition adds an eco-friendly edge, while also ensuring easy clean-up with warm soapy water. With HD Timber Coating, you can confidently protect and preserve your timber structures, enhancing their longevity and resilience against harsh weather conditions.
