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. Suitable for interior and exterior use. Rustins Wood Hardener extends the life of rotted wood, therefore being a cost effective alternative to wood replacement.
