  • Wear protective gloves to avoid getting hardener on your skin. Open your doors and windows for added ventilation. Remove loose or crumbling wood and make sure the area is dry. For the best repairs, drill small holes into the wood so hardener can get in deeper.

Leave it to dry for two hours. Scrub with a wire brush to get rid of any excess hardener. Clean your tools with white spirit.
