Wood hardener is used on construction sites to stabilise timber that’s been affected by decay, impact, or moisture. It reinforces compromised wood by soaking into the fibres and setting solid. Builders apply it before filling, repairing or repainting exterior and interior timber, especially in windowsills, door frames, fascia boards, and cladding. In modern practice, it’s a preparatory step that saves replacing entire sections of wood. It can also serve as a primer on weathered timber to provide a reliable base for coatings or finishes. 
Most wood hardeners are solvent-based liquids designed for use on softwood or hardwood. Some are fast-drying, while others allow more working time before curing. Wet rot wood hardener is a specialist type used to treat rot-damaged areas in structural and decorative timber. It’s more efficient than older techniques like splicing or scarf-jointing, especially where complete removal of decay isn’t feasible. Choose between general-purpose or rot-specific products depending on your site needs and timber condition.
