I love this stuff and have used it for years! Its great for fighting dry-rot in thresholds, mouldings, door casings, and window frames. it makes a huge mess if you spill in though! I use a small mixing container and a 1/2" disposable brush to apply it generously and then give it plenty of time to seep in and dry. It works best in porous wood.

Yep it worked

I was doing a repair project for my wife’s wooden porch swing. The arm rests had quite a bit of rot with one I thought would need replacing. I heard about Minwax Wood Hardener so I thought I’d give it a try before ripping pieces apart. I was pleasantly surprised at how well it actually worked. I followed the directions and it is amazing how stable the wood became. It took a little effort to shape one of the rests after applying a wood filler but with patience and a good sanding I got it right. I applied the hardener to one seat slat and a few other spots and it’s like concrete! I actually placed a couple of screws through some areas and it’s holding up. It saved me from having to buy limber and making saw cuts. You can even paint over it. Very satisfied.
