PC Products PC-Petrifier Water-Based Wood Hardener, 32 oz, Milky White 324448

We use this to harden and petrify old wood and found drift wood out of the river. No odor to speak of, goes on easy with brush and gives a nice tone to the wood. The wood goes a little darker and richer. Quick to dry. Only thing to be careful with is that it is very thin and if not careful you lose a lot off the brush trying to get it on wood. The advantage of being thin is that it seeps into cracks and crevices well. Have used it on old deck wood as well. Would recommend.

Great product. I used it for hardening some dead wood to create few decorative craft projects. Worked so well that it was tougher than original fresh wood!! I mean, I had to saw off some to fine tune the craft item and I realized how hard it was. Before hardening the old log was so dead I had to be so careful not to break it while gentle cleaning.

Works better than expected, easy to apply and doesn't make a mess. I had to repair a very large raised wood deck that had significant dry rot and insect damage. I cleaned out all of the damaged wood then tried this product to one of the beams. At first I couldn't see any effect, then when the first coat was cured, I applied a second, heavier coat and saw the results. The wood had become very hard and dense where the rot had been and prevented additional rot by weather proofing the wood. Particularly effective on the very porous board ends that have a tendency to rot as they absorb water. The board ends now are water tight. I also tried the traditional rot solution that required a two part epoxy to be mixed. This was fine for heavily rotted areas that needed to be filled, but was a lot of work and too expensive for large areas. Application Tip: I found that a plastic "glue" needle plunger worked great to inject the wood hardener into holes in the wood, left by pests or ones I drilled to get deep into the wood. Very inexpensive, and effective way to prolong the life of important wood that will not be visible (substructure, or surface coated).

great stuff. i pulled a toilet that had a bad wax seal so water was leaking onto the subfloor under toilet. who ever built the house left a large cutout and the toilet flange. now i had to dry out all the exposed wood. scraped the soft water logged wood away. once it was dry i used this petrifier. it was sucked right inthe wood and 24 hours later the wood was hard as concrete. this allowed me to fill in around the new flange i put in with gorilla all porpose wood filler. once the area dried and level , the flange was not free floating anymore. i was able to screw the flange thru the woodfiller to the petrified wood unde the putty. this petrified product worked great and i didn't have to cut out the old floor and replace with new plywood and lay a new finished floor. highly recommended product

This is a good product.It worked well for me

I am repairing 125 year old rotted wood old growth fir window sills. PC Hardener soaks right into the wood and hardens in a few hours. After it drys you can tell if you missed a spot by sticking your finger nail or a screw driver in to see if in resists. Easy to apply to a horizontal surface. You need a brush for vertical surfaces where it tends to drip or narrower areas like window trim that is fluted. I bought a box of cheap chip brushes to work with the hardener. Virtually no odor! I bought the smaller size 32 oz to see how it worked and how far it would go. Photos are before and after on west and east facing windows and typical of the rotted weathered sills on my house [30" wide 6" deep] with deep cracks, some of which go almost al the way trough 2" thick wood. One 32oz container hardened four window sills and the 24oz PC Woody epoxy filler set was enough to fill those four sills. Easy to clean up spatulas and hands with denatured alcohol. Easy to sand the epoxy with 80 grit sandpaper. It feels like a great surface to paint too.

This product is meant to be used for wood that is rotted or starting to rot. I read one review in which claimed that it was like water and ran down the board. It isn't meant to be used on healthy wood. I have exterior staircase all wood that have started to rot where the screws were put in. I have followed the instructrions and used a screw driver to pull out all of the rotted wood and made sure what was left was dry. I have used a glass spray bottle and a squirt bottle to put on to both small areas and large areas of rot. This product soaks into the wood like a sponge - you have to let it dry and then reapply until the product pools in the area where there is rot. The next step after treating the rotted wood with this product is to use PC Products 2 part epoxy to then fill the area or hole where the wood was rotted. I was looking at close to $5,000 in replacement costs for the stairs and deck. I did replace approximately 12 boards that could not be saved. The rest are all being treated with the two products and the results are absolutely amazing. Even if I only get another 5 years out of the stairs and deck I will be happy. But now that I know what the problem is I am working to stop the rot before it has a chance to spread. I am guessing the overall cost to me for materials will be $600 which is well worth it. It is labor intensive so it is not for lazy people who would rather pay someone to just replace the wood.

Faced with the prospect of having to tear out the joists of my wooden deck, I was ready to try anything. Luckily, I tried this stuff. And, to my surprise, it really, really works. Sure, I should have used pressure-treated wood; I erred on the side of budget -- and ended up paying for it a few years later. But this spray-on, pour-on solution has given me, hopefully, several more years of utility from my decking and joists. (I did have enough forethought to use treated lumber for the beams.) I wire-brushed the fungus and punk wood away, exposing a porous surface; sprayed the vertical surfaces and poured a thin stream into the grain of the horizontal ones. Waited for it to harden, then gave it another coat. The wood appears solid and rock-hard now (or at least wood-hard). Cleanup is easy with water before it hardens. The liquid is thin enough to work with a hand spray-bottle and to soak into the wood, and milky when wet. A thin coat dries mostly clear.

i love this stuff. i do quiling and it makes all my creations go from paper to a stiff almost like wood,

Product is good but unfortunately the time to deliver is way too long!

I sanded as much as possible with some opaque outdoor wood stain remaining on the window sills to be treated. Then I brushed on the product which seems to soak ok into the wood. But looking at the treated sills a year later, I notice that the product has lifted parts of the remaining stain, meaning that I have to redo the job. I think I will stick with 2 part epoxy. Too bad, I liked the simplicity of this product.

Does exactly what it says. Easy to use and works

This seems to do what is written on the bottle. It does hard on the wood but does not leave it as hard as natural wood. It seems a bit pricey for the size of bottle.
