What Customers Are Saying

The wood hardener appears to effectively restore and strengthen damaged wood, allowing users to fill holes, cracks, and other issues. It was described as easy to apply with a quick drying time, and worked well on various wood types including exterior surfaces. However, some users reported issues with the product turning the wood surface white or chalky after getting wet, and difficulties with the packaging. Overall, the wood hardener seems to be a reliable solution for repairing rotted or damaged wood, as long as instructions are followed carefully.

This really works well! I was pleasantly surprised how well it solidified some plywood on my home-built boat.
