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.

This product is used to stabilize punky or slightly rotted wood. I use in wood turning when I want to stabilize a piece that has interesting color but is a bit soft. The hardener will soak in and must be allowed to dry before using. I have also used it for repairs (house, e.g. window frames usually on the bottom where water has caused some damage. Once the liquid has dried the wood has hardened and can be repaired if needed with corresponding filler product, sanded and refinished. Drill first if using screws. Liquid is very sticky and can be brushed on. I use two "coats" when the damage is extensive. The filler drys very hard so try to get the filling smooth and use two fillings if damage is deep.
