West System® 12 oz Wood Rot Repair Kit. For small repairs or single spots. A penetrating epoxy system designed to stabilize rotted, deteriorated wood without requiring full replacement. It soaks deep into damaged wood, reinforcing it from the inside out. The flexible formulation moves naturally with the wood so it won't crack over time. The epoxy has a working time of 30-40 minutes (at 72 degrees Fahrenheit), giving it plenty of time to migrate through the wood before it begins to cure. Each kit includes a reusable mixing bottle with pre-printed measurements making it easy to mix and apply. Kit comes with gloves and detailed instructions.
