West System Wood Rot Repair Kit

Damaged or rotten wood does not always need to be replaced. With the West System Wood Rot Repair Kit, you can repair and strengthen wood affected by rot. The low-viscosity epoxy penetrates deep into weakened wood fibres and bonds them back together. This allows you to repair damaged wooden components without having to replace them completely.

The epoxy is 100% solvent-free and remains slightly flexible after curing. This allows the repair to accommodate the natural movement of the wood. Suitable for boats, window frames, motorhomes, caravans, furniture and other wooden structures.

Benefits of the West System Wood Rot Repair Kit

• Strengthens wood fibres affected by rot.
• Low-viscosity epoxy penetrates deep into porous wood.
• 100% solvent-free.
• Remains slightly flexible after curing.
• Can be combined with West System fillers.
• Suitable for filling voids and rebuilding missing sections.
• Can be sanded and finished after curing.

Repairing wood rot without replacing the entire component

Wood rot is often localised. If enough sound, solid wood remains, you can repair the affected area instead of replacing the entire component.

West System Wood Rot Repair Epoxy penetrates the porous, weakened wood structure and consolidates the remaining wood fibres. Once cured, it creates a solid base on which you can continue to build up and finish the repair.

Repairing missing wood and larger holes

Are sections of wood missing or have larger voids developed? Mix the wood rot repair epoxy with a suitable filler. This thickens the low-viscosity epoxy into a paste that can be used to fill voids or rebuild missing sections.

Once cured, the repair can be sanded, shaped and finished as required.

Applications

The West System Wood Rot Repair Kit is suitable for applications including:

• Boats and yachts.
• Window frames and exterior joinery.
• Motorhomes and caravans.
• Furniture and woodwork.
• Wooden components and structures.
• Restoration and repair projects.

Instructions for repairing wood rot

1. Remove any loose, soft or severely affected wood.
2. Make sure the remaining wood is sufficiently sound and solid to provide a suitable base for the repair.
3. Mix the epoxy resin and hardener in the specified ratio.
4. Apply the low-viscosity epoxy to the affected wood and allow it to penetrate the weakened wood fibres.
5. If necessary, fill larger holes or missing sections with epoxy thickened with a suitable filler.
6. Allow the repair to cure completely.
7. Sand the repair to shape and finish the surface as required.

Application and curing

At an ambient temperature of approximately 22 °C, the following values can be used as a guide:

• Recommended application temperature: 22 °C.
• Minimum application temperature: 10 °C.
• Working time at 22 °C: 30–40 minutes.
• Further build-up: after approximately 3 hours.
• Overcoatable when applied in a thin layer: after at least 12 hours.
• Sandable: after approximately 24 hours.

Actual working and curing times depend on factors including the temperature and the amount of epoxy applied.
