Ronseal High Performance Wet Rot Wood Hardener Clear, 250ml

Ronseal High Performance Wet Rot Wood Hardener Clear 250ml

Rotten or decaying wood doesn't always mean the entire piece of timber needs replacing. Ronseal High Performance Wet Rot Wood Hardener is specially formulated to strengthen weakened wood, helping you restore damaged areas and prepare them for lasting repairs.

Ideal for tackling wet rot damage around wooden doors, window frames and other interior or exterior timber, this powerful wood hardener penetrates deep into soft and decayed wood fibres. Once dry, it sets rock hard, reinforcing the remaining timber and creating a firm, stable surface ready for filling.

Whether you're repairing a rotten window frame, restoring a wooden door or dealing with small areas of deteriorating timber, Ronseal Wood Hardener helps make the repair process more straightforward.

Its clear, solvent-based formula is applied using a paintbrush and requires just one thorough application. With a drying time of approximately two hours, you can move on to filling cracks, gaps and damaged sections without an unnecessarily long wait.

For the best results, remove loose or crumbling wood before applying the hardener, ensuring the remaining timber is dry. Once hardened, the treated area can be repaired using a suitable wood filler, such as Ronseal High Performance Wood Filler.

How to Use

1. Prepare the wood: Remove any loose, soft or crumbling timber and ensure the remaining wood is completely dry.

2. Improve penetration: For deeper repairs, drill small holes into the affected wood to help the hardener soak further into the timber.

3. Shake thoroughly: Shake the tin well before use and pour a small amount into the plastic lid.

4. Apply generously: Using a paintbrush, apply the wood hardener until the affected wood is thoroughly saturated.

5. Allow to dry: Leave the treated wood for approximately two hours to harden.

6. Prepare for filling: Remove excess surface hardener using a wire brush, then fill any remaining holes or cracks with a suitable wood filler.

7. Clean your tools: Clean application equipment using white spirit, following the product instructions.
