Review: Amazing Stuff - 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.
Review: Really hardens rotted wood and allows repair. - 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.

## Questions & Answers

**Q: Can you apply this over painted ends of fascia boards to prevent dry rot?**
A: I have been using this product for almost 20  years.  (see my review). I doubt if using it over 'painted' wood would be of value as you want the polycarbonate to penetrate into the end grain. I have facia boards that have been in place for more than 15 years and they show no signs of decay. I live in Mobile, AL. We get over 60 inches of rainfall a year. On facia work, I install clear, pressure treated wood. Once the ends are cut, I liberally treat the end grain.  I then prime both sides of the board, including the cut, with an oil base (alkyd) primer. Lastly, I overcoat with one coat of the finish paint.  Then I assemble and put the finish coat on the outside. Yes, it is a lot of trouble but years later the facias are still in like new condition.

**Q: My question is two part: 1st; is this product clear? 2nd; has anyone used it for stabilizing small wooden pieces under vacuum?**
A: Yes it is clear.  Yes I have used it under vacuum on 3/4 X3/4 X2 1/4 inch pieces of wood.  I make wood pens. DO NOT use it after you drill the hole and put in the brass tube. I does dissolve the epoxy glue.  I left my vacuum over night.

**Q: Can this be injector through carpet into a bad spot of wood?**
A: This product loves to attack literally degrade and melt many plastic and man made materials as well as rubber like substances especially if they also have a plastic polymer in their formulation. Anyway carpet often has polyester and urethane materials not to mention foam backings or some kind of material painted over the back to stabilize it. This product most likely would attack all of those. Pull your carpet up from the edges rolling it back to where the wood needs treatment. Once it's dry and smoothed out then roll the carpet back and rent a stretcher to reapply the carpet properly back into place. Buy extra nail board if that was used along the sides of wall tow all carpet. Or glue strips of that was used instead. You also run the risk of super glued down carpet that hardens and sets to the wood and when you would need to replace the carpet it would tear bits of wood if not chunks of wood up with it as you tear the carpet or attempt to tear it out. So the best answer directly to your question is "NO."  Treat the wood not the carpet.

**Q: Is this water soluble?**
A: It acts similar to CA (superglue) in that it displaces the water in the wood.  Definitely not water soluble as water tends to increase the reaction time.

### ⭐⭐⭐⭐ Easy to apply, Good for light duty jobs
*by R***Y on May 9, 2018*

Definitely does the job, and it's easy to use. I bought it primarily to seal some of the boards on my wooden deck. It's good for sealing the end grains of the boards, and to waterproof the areas when water drips on the deck. You can paint or stain over the wood after the hardener dries. For serious wood issues like insect damage or rot, I get better results from a two-part wood hardener. But for light duty, this is great stuff. I like that it is thinner than the two-part epoxies and can be applied with a syringe. If you see some wood getting soft, just drill some small holes in the affected areas and squirt some hardener in with a syringe. Fill the hole with wood putty and its good as new after a coat of paint. This works great and will save you hours of work. It takes hours to dry, but that's good because it takes time to penetrate the wood fibers. If you are looking at it, give it a try.
