Earl’s Wood Hardener — Restore Soft, Rotted Timber Like New
Bring weakened, decayed timber back to life with Earl’s Wood Hardener. This water-based consolidator penetrates deep into soft, rotted fibres and bonds them into a tough, stable base that’s ready for filling, sanding, and painting. Use it to save windowsills, frames, posts, decking boards, furniture, fences, and more—without costly tear-outs or replacements.
Why Customers Love It
Repairs instead of replacing: Restores soft, crumbly timber to near original strength so you can patch and repaint.
Water-based formulation: Low odour, no volatile organic compounds, and non-toxic when cured.
Ready to use: Pre-mixed; just shake and apply—no diluting or measuring.
Works inside and out: Ideal for interior and exterior timber exposed to weathering.
Versatile application: Pour, brush, spray, or syringe to saturate deep into affected areas.
Long shelf life: Stays usable for extended periods when stored correctly.
Proudly Australian made: Developed for local conditions and everyday DIY and trade use.
Where to Use
Window sills and sashes, door frames, posts, fences, balustrades, fascia boards, decking edges, outdoor furniture, indoor furniture, trims, mouldings—any non-structural timber showing soft rot or fibre breakdown.
How It Works
The thin, penetrating formula wicks into softened timber fibres. As it cures, it binds those fibres together to form a firm, stable base that can be filled, sanded, and coated. No need to carve out all the rot—thorough saturation does the heavy lifting.
Directions
Prep: Ensure the area is dry. Remove dirt, dust, grease, loose paint, varnish, and flaky wood. Mask adjacent finishes if needed.
Apply: Shake well. Generously pour, brush, spray, or syringe the hardener into the affected timber. Repeatedly saturate to drive product deep into fibres.
Cure: Allow to cure until solid and no longer tacky to the touch. Extremely soft timber may need multiple treatments.
Repair: Fill voids with a compatible wood filler, let set, then sand smooth.
Finish: Prime/seal and paint or coat as desired.
Pro Tip
For deep penetration around a localized patch of rot, mark approximately 75 mm either side of the soft area and drill small holes between those points. Brush, spray, or syringe the hardener into the holes until saturation is achieved.
Clean-Up & Safety
Clean tools and drips with water while wet.
Use above 7 °C and in well-ventilated areas.
Non-toxic when cured. Always follow label directions and keep out of reach of children.
Compatibility
Once cured, the hardened substrate accepts most timber fillers and putties. After filling and sanding, it can be primed and top-coated with typical timber paints and finishes. Always test on a small area for compatibility.
Limitations
Not for structural load-bearing repairs.
Not recommended for constant water immersion or areas that cannot be dried prior to application.
Timber must be reasonably sound after consolidation; heavily degraded material may require multiple treatments or replacement.
