Rustins Wood Hardener for Rotted 500ml (Packaging may vary)

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. Wet Rot vs Dry Rot: Formulated to consolidate wet-rot-damaged timber (soft, decayed wood from moisture) as part of a standard filler-and-repaint repair - not a treatment for active dry rot fungal infestation, which needs specialist removal.
