Rustins Wood Hardener is suitable for interior and exterior usage. It is a solvent based moisture curing polymer solution designed to penetrate deeply and harden rotten or decayed wood. Once fully dried, it strengthens and reinforces the deteriorated wood to support the use of wood filler and provide a seal against further moisture penetration. It extends the life of rotted wood. Can dry in 2 hours to allow rapid completion of repair work. 

Intended Use: Rustins Wet Rot Wood Hardener is designed to penetrate deeply into and harden rotten or decayed wood. Once fully dried, the polymer strengthens and reinforce the deteriorated wood to support the use of wood filler and provide a seal against further moisture penetration.

Available in both 250ml and 500ml or 1 liter

Usage Instructions:
Preparation: Remove loose, decayed or very soft wood until a fairly sound base is exposed. Rustins Wet Rot Wood Hardener is moisture-hardened, however the wood should be reasonably dry and free from grease, dirt and oil.
Application: Shake well before use. Apply liberally by brush, saturating the wood. Wait until each coat has been absorbed by the wood and reapply. Ideally this should be done as a continuous process for maximum penetration depending on the absorbency of the wood. Continue with repeated applications until a surface film is formed.
Coats: Multiple coats. This is a continuous application process, (see above).
Drying Time: 5 minutes, (see above). Allow a minimum of 2 hours before applying Rustins Wood Filler over Rustins Wet Rot Wood Hardener or until hardener film becomes fairly touch-dry.
Re-coating Time: 5 minutes, (see above). Allow a minimum of 2 hours before applying Rustins Wood Filler over Rustins Wet Rot Wood Hardener or until hardener film becomes fairly touch-dry.
Application Temp: Ideally between 15-25ºC. Do not apply below 10ºC.
Coverage: Not applicable. Dependent on condition of rotting wood.
Compatibility: Avoid contact with metal, glass, plastic and painted surfaces.
Settlement: Shake well before use.
Shelf-life/Storage: Many years if suitably stored unopened in original container. NOTE; this is a moisture-hardened product so storage life of opened tins is limited.
Clean-Up: Clean equipment with Rustins Cellulose Thinners. Turpentine or White Spirit are unsuitable.
