## Overview

Rustins Wood Hardener is a solvent-based, fast-acting formula designed to penetrate and reinforce wet-rot-damaged timber. It cures within an hour to create a solid base for fillers and paint, suitable for both indoor and outdoor wood repairs. Easy brush-on application and moisture resistance make it a must-have for professional-grade wood restoration.

## Description

Penetrates deep into wood to revitalize and fortify weakened or decaying areas, creating a solid foundation for any wood project. Ideal for indoor and outdoor use.

## Features

- Causes serious eye irritation.
- Causes skin irritation.
- Harmful if inhaled.
- Harmful in contact with skin.
- Highly flammable liquid and vapour.
- May cause allergy or asthma symptoms or breathing difficulties if inhaled.
- May cause an allergic skin reaction.
- May cause drowsiness or dizziness.
- How It Works: A low-viscosity resin that soaks into soft, wet-rot-damaged timber and cures to re-solidify the wood fibres from within - creating a firm base that holds screws, filler, and paint, instead of crumbling. Use Before Wood Filler or Paint
- Cure Time: Touch-dry in around 1 hour and ready for wood filler or overcoating the same day (confirm exact timing on the tin before publishing) - so most repairs can be filled and painted in a single session.
- Simple Brush-On Application: Apply liberally with a brush to soft, dry, sound-enough timber until it stops absorbing - no mixing, no special tools, ready for wood filler once cured.
- Indoor & Outdoor Use: Wet Rot Repair, suitable for window sills, door frames, skirting, decking, fence posts and fascia boards, both indoors and outdoors, once painted or sealed over for exterior protection.
