Rated 5.0 out of 5 by 5 reviewers.
Rated 5.0 out of 5.0 by Great Product I use this primarily as a stabilizer for heavily / overly spalted hard woods and as a hardener for soft porous woods. For small spalted crafts pieces, I soak them overnight in a large mason jar, or for larger pieces, in a custom made container. Once thoroughly dried, even spongy soft pieces are similar in hardness to White Oak. PROS: > Dries Quickly > Penetrates deep into the wood > Sands well after 24hr drying > Does not seem to affect glues when thoroughly dried. CONS: > Needs to be used out-doors due to very strong odor. > Quickly gums up sandpaper if not thoroughly dried before sanding. > When liquid, can dissolve any products that use Acetone as a solvent, especially with prolonged exposure. > Doesn't come in Gallon size August 21, 2012
Rated 5.0 out of 5.0 by For Craft People Besides wood...if you do any cardboard projects, paint this stuff on...cardboard will get hard as plastic and can be sanded smooth. Do this outdoors as this stuff is a bit smelly. May 8, 2011
Rated 5.0 out of 5.0 by Minwax Wood Hardener There were a couple pieces of railing out on my front porch that were starting to soften and eventually rot right through. I really hated to replace the boards just for a couple small patches. I looked this product up and decided to try it. I applied the hardener and within a couple hours it had dried. I recommend two coats, but even with one coat the product worked very well! The once soft patches are now very hard and durable. February 29, 2012
Rated 5.0 out of 5.0 by Minwax Wood Hardner I have used this product in several exterior jobs and it has stabilized the wood, and saved my having to replace that piece. It takes a finish fairly well, and saves a lot of work! June 3, 2010
Rated 5.0 out of 5.0 by Great Stuff! I used this stuff to repair custom window sills in customer's home. The great thing about this hardner is that it dries super-fast! May 15, 2012
