Minwax High Performance Wood Hardener, 1 Pint

works quickly and works miracles. its a great for beautiful but neglected wood floors. a small section of the bedroom where a camber pot was set up (and obviously spilled and never cleaned) will still need to be replaced but two other spots in the house that werent properly cared for but urined on wont. im confident the worst area wont crumble further while saving up for a professional to replace it.

works well and as intended. good value

Great for paint prep on punky surfaces such as decks railings and window sashes.

I'm a gourd artist. Even though gourds have a hard, thin, sometimes brittle, outer shell, the inside part of the shell is soft and porous. After cleaning out the seeds and pulpy "gunk", I coat the gourd's interior with Minwax High Performance Wood Hardener. Once dry, the gourd can be easily carved.

[This review was collected as part of a promotion.] Standing in the stain isle you see a number of Minwax products. I often wondered how some of the products performed so I finally decided to test them out before my next project. The hardener has a low viscosity, easily spreads and quickly soaks into wood fibers. It is tacky within minutes and dry enough to sand or use Minwax's high performance wood filler in about two hours. The vapors smell similar to a pvc primer but with good ventilation, it isn't something that lingers. You need multiple coats but they happen fairly quickly. The hardener makes the surface easier to sand and prepare for finishes. After the product has cured, it makes a slightly higher pitched sound when you tap it. I applied solid stain and have the following observations on the difference between hardened word and bare wood. The hardener seals up the wood but remains ready to accept a finish. The solid stain did not seem to soak into the wood but it did adhere strongly to the surface. The color was fairly even and the final finish was richer. The unfinished wood side was rougher, duller and needed more coats to even out the color. The Minwax hardener is like a thin, clear, nail polish. It helps you sand rough wood and stops moisture absorption which is great for areas where you need to use a hard filler. It makes a strong interface between two dissimilar materials and helps preventing the patch from failing. It is worth the investment for use on repairs or finishing end grain.

Works great on old wood to harden it.

Needs only a small amount to be effective. I use a syringe with a plastic tube connected to facilitate minimal useage. Hardens rotted wood.

Had a garden shovel with wooden handle severely weathered from being left outside,thought it was beyond recovery with linseed oil. Treated with multiple applications of Minwax wood hardener and brought it back to life. Now feels as solid as new.

Product works great, I have used to to repair rotted sills etc. But the cap can be almost impossible to remove. I had to throw away my first partially used bottle because the cap was glued on. Now I clean the lip and cap carefully before recapping. Even then it takes much too much downforce for the safety cap to work properly. For my most recently purchased bottle I had mount the new bottle in a vise, and use all of my weight as a down force to eventually open it. But now the thin metal of the cap and spout look stripped. We will see if I am able to open it later.

Frustrating! The lid says to push down and turn to open. I did this..over and over...tried different angles...varied amount of force. After 10 minutes of struggle I was still unable to open it. I went online to try to find a video of how to open the product. No luck...just other reviewers stating they had the same problem. Glad to know I'm not the only one.
