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.

Clean-Up: Clean skin and tools immediately with warm soapy water.

Safety: Keep out of reach of children and pets. Wear gloves and eye protection during use, and avoid contact with clothing. In case of eye contact, rinse thoroughly with clean water. If irritation persists, seek medical advice. If swallowed, call a doctor or poison centre immediately.

Drying time may vary depending on temperature and humidity.

Product Instructions

Application:

Walther Strong Timber Coating can be applied with a standard paint brush or a heavy duty roller. For best results, apply a generous and even single coat directly onto clean, dry timber. Use above 4°C in dry conditions, and avoid application on damp or contaminated surfaces.

The coating is quick drying, becoming touch dry in as little as 20 minutes*, and will fully cure within 24 hours at 21°C with average humidity. Once cured, the surface may remain slightly tacky to the touch – this is normal and will not affect performance.

(*Drying time may vary depending on temperature and humidity.)
