Used on mull posts on my front entry door. The bottoms had rotted about 4-5 inches up. The kit was perfect for what I needed. The initial product hardens the rotted wood, after you remove the worst of it. You apply it the day before the epoxy. I applied the epoxy 3 times in order to get it properly shaped. Each layer bonded well to the prior layer. The initial layer bonded well to the rotten wood. It shapes and sands well after it hardens. Hardening time varies a lot depending on the temp, but that's okay and to be expected. Also, the instructions were well written, informative, and easy to follow. The only downside is that you don't get much epoxy.

Ok. This is tentative until spring. I have no idea how it will really work until it gets through the winter. However, this is a great package. Its got everything you need to make repairs from large to small. Its very easy to work, you've got plenty of time to work before it sets, and it sands and paints very well. They sell larger quantities if you got more than a few repairs to make but this allowed me to fill in two large rot spots in my deck and repair about two inches of the bottom of a 1x6 that had rotted out. The little tube of caulk like patch is quite interesting. Its actually an epoxy with two different layers held together until they're worked. Overall a very nice package

Superb product for small wood rot repairs. I had minor wood rot in the usual places - lower door jam where it meets the threshold. I scraped out the rotted wood, used the wood hardener, and then filled it in with the epoxy filler. I figure the volume was about 2 cubic inches total. 24 hours later I sanded it smooth and painted it. Looks like new. I did another small project where a steel door had some rot in the inner wood core on the hinge side and it filled than in perfectly. Some tips: When you apply the epoxy, don't put it on too thick because it is hard to sand it. After it dried I just scraped it with the edge of a utility knife to get the shape (a sharp blade at 90 degrees to the epoxy works great to scrape off layers much quicker than sanding) I wanted and then it sanded out. This also makes it easy to get an edge on a board to make it look like one piece of wood. Great product and would recommend this to anyone! markowaleski.com

Very good stuff, you can repair just about any type of rotting or rotten wood with it. Obviously, surfaces have to be dry and free of debris, but other than that this stuff will get it done for you. And no, nobody paid me to write this review and nobody gave me free stuff either - I bought these full price so my money is where my mouth is. I vote we ban the paid reviews on products, who's with me? Anyway, I repaired my deck and couldn't be happier with the process - very simple, just apply elbow grease and you can turn old, creaky, dry-rot into solid, like-new wood textured surfaces. Sanding and painting optional.

This stuff is perfect for those places that you don't want to replace, but which are rotted. I fixed an outside window sill that was completely rotted away. It was a complex, mitered angle on a bow window. With some patience, a rasp and a sander, i was able to make it look like new. When it is painted it will be indistinguishable. This comes out of the can like peanut butter, but when it is hardened it works just like wood.
