Pc-petrifier Water-based Wood Hardener, 470ml Bottle, Milky White

Works very well used it on woodworm damaged wood and rotten exterior wood. Takes longer to dry then solvent based products but has almost no smell so is brilliant to use indoors. Expensive but goes a long way. Won't be using solvent based hardener indoors ever again.

Ich suchte schon immer einen guten Härter. Ich mache in meiner Freizeit Papier Schmuck, und dafür suchte ich einen guten Härter um meine Schmuckstücke Alltags tauglich zu machen. Mit diesem Holzhärter hat es nach langen ausprobieren mit anderen Produkten endlich geklappt. Er Riecht nicht unangenehm und trocknet sehr schnell

Clean-up Tip for PC-Woody 2-pt epoxy – Wear disposable gloves. Use nail polish remover (acetone based) to clean working tools. (You can also use denatured alcohol). As soon as you’re finished using the 2-pt epoxy, wet a paper towel with nail polish remover and wipe your tools (metal or plastic); the sticky epoxy immediately melts away. In 2010 I first used PC-Woody petrifier and 2-pt epoxy filler to repair a cedar fence post and cedar gate which were splitting. Also, the screws for the gate hinges & latches were loose and falling out due to the cedar softening from old age (26 yrs). I applied 2 coats of the petrifier solution to harden the deteriorated sections and then filled the areas with 2-pt epoxy. Worked great – now 5 yrs later in 2016, the posts and screw holes are still hard as rock and the hinges & latches haven’t budged. In 2011 the fence was painted with 2 coats of water-based exterior solid stain which covered the repaired areas very well; still looks good today. This year my rough-cedar exterior stairs has tiny vegetation growing on top of the top two treads, as well as on top of my cedar picnic table. I have no idea what type of plants they are (could be lichen), but they have bright tiny orange/yellow flowers with short white roots. Warning – get rid of plant growth in wood as soon as you see it! Unfortunately, if left too long the vegetation eats and rots the wood from inside out making it soft and spongy. I sprayed twice with 50/50 bleach & water solution to kill the vegetation and covered the area with plastic to keep out the rain. After the vegetation died, I dug out the soft rotted wood portions, which left huge voids in the treads. I applied 3 applications of PC petrifier which hardened the rotted sections. Using a plastic putty knife/spatula, I filled the voids with PC 2-pt epoxy on 3 different days in order to build up the damaged area and allowed the epoxy to dry 24-hrs between each application. The epoxy is now hard as rock ready to sand and paint. After sanding with coarse-grit sandpaper, I painted using Benjamin Moore water-based solid stain, which covered the repaired areas without any problem. The stain on the repaired areas dried slightly lighter than the wood, but it’s by far a vast improvement over the rot-damaged look. The finished top tread looks a bit rougher in grain texture, rather than totally smooth, but I needed the rest of the epoxy to repair the picnic table. Since the stairs are made from rough cedar, I’m not too concerned, as the wood already has a naturally rough appearance. Time will tell as to whether it will maintain its weight-bearing strength and although the top tread sustained considerable wood rot, it now feels completely solid and safe. For the stairs I used 1 1/3 (16-oz) bottles of petrifier and 1 1/3 (12-oz) cans of 2-pt epoxy; the remainder I used for the picnic table. Overall, I’m very pleased with the finished result and highly recommend PC-Woody petrifier and 2-pt epoxy for similar repairs.

Using this to stabilize old rotted timbers on a 100-year-old Tudor-style exterior. I had been using the Bondo wood stabilizer, which is a good product but it's spirit-based and smells awful and not good to breathe. This product is water based but still manages to absorb into the wood very effectively. Dries overnight (the Bondo product is faster, a couple of hours) You can kind of squirt it on a horizontal surface and brush it in. For vertical surface, I have found that the best method is to pour a little of this stuff into a party cup and use a cheap bristle brush (1 inch artist's brush works well) and just kind of dab it into the wood. The main purpose of this product is to harden the surface of rotted wood so there's a stable base for an epoxy putty (bondo or any of the specialty play-doh type putties.) which you use to fill the holes and recreate the shape of the wood. The putty itself is rock hard so it needs something hard to hold on to, otherwise the whole thing would fall apart when you shape and sand the hardened putty. Anyway I like this and the price (while not cheap) seems reasonable. This bottle will probably handle 5 or 5 square feet of wood surface that needs to be treated.

Use for outdoor window area . Strong. Worked as described. Easy to use. Two applications.
