How to strengthen wet rot wood

Before you start

Wear protective gloves to avoid getting hardener on your skin. Open your doors and windows for added ventilation.

1. Remove loose or crumbling wood and make sure the area is dry.
2. For the best repairs, drill small holes into the wood so hardener can get in deeper.

Application

1. Give the tin a thorough shake.
2. Pour some of the hardener out into the plastic lid.
3. Apply it with a paint brush. Make sure you get enough on so that it completely soaks into the rotten wood.
4. Leave it to dry for two hours.
5. Scrub with a wire brush to get rid of any excess hardener.

Aftercare

Once you’ve used the hardener, you can focus on repairing the wood and filling any holes or cracks with Ronseal wood filler.

Cleaning

Clean your tools with white spirit.
