PC-Petrifier Water-Based Wood Hardener, 8 oz, Milky White 84441

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.

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

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).

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.

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.

I used in a tank sprayer on the rotten ends of my redwood deck boards. I'll see this winter if it actually works. Easy water cleanup.

Worked great

Best Wood Hardner I have used easy to put on.

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!

C'est vraiment utile ce produit. Je l'utilise fréquemment dans ma vieille maison. Ça permet de solidifier le vieux bois qui est en place et ça nous permet de faire une réparation très durable. À combiner avec le PC-Woody.

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.

I have used this product extensively for repairing various types of wood including partially wood window frames, weakened plywood, and severely weathered garage doors and window sills. It can restore the integrity of the wood and create a strong new surface to which paint can easily bond. On old wood window frames, it allowed me to reuse the old frames (they've been in use now for 7 years and are still fine. The PC-Petrifier restored rigidity to old very weathered plywood that I thought I must replace. After applying the product, I primed and painted the plywood and it remains in very good condition after 2 years. A neighbor and I also used it on our garage doors to restore the integrity of rotted wood before repainting the doors. The doors look like they are new again, and I expect them to last another 25 years. This is a great product.
