Description
Walther Strong HD Timber Coating is a quick drying, rubberised waterproof liquid designed to protect hard to tape timber areas such as exposed ends, ledger boards, stringers, posts, notches, wall plates, and sleeper retaining walls. It forms a durable moisture barrier that helps prevent water ingress, rot, and decay, extending the service life of timber structures exposed to harsh conditions.
HD Timber Coating is ideal for sleeper retaining walls, providing a tough waterproof barrier that helps extend the life of sleepers exposed to ground moisture and weather. It is fast to apply and can save significant time on site, especially on larger sleeper projects. Simply brush or roll it on to seal joins, cut ends, and exposed sections where water typically penetrates first.
For decking installations, HD Timber Coating can also be used alongside Walther Strong Deck Tape for complete timber protection. Deck Tape is designed to protect joists by creating a consistent barrier along the top surface, helping prevent moisture build-up around fastener penetrations. HD Timber Coating is then used to seal the vulnerable areas that are difficult or impractical to tape.
HD Timber Coating covers approximately 3–4m² per litre/kg, making it highly efficient for professional and DIY applications.
