J-B Weld 40006 Wood Restore Premium Epoxy Putty Kit - 32 oz.

I really like this stuff. I have read reviews that struggle with mixing or applying this putty. I guess that I have a lot of practice and have used different versions of J-B Weld Epoxy and now I have needed the wood restore product to replace areas of wood in quite a few places in our home. When it sets - it is much firmer, denser, and sturdier than other wood putties because it is "Epoxy"! There are just a few tricks to its use. I use nitrile gloves to both mix it and apply for a small amount. If I need more, then I mix it in a container but the gloves are much easier. I use a putty knife to apply the putty to gaps in wood whether on a corner or on a flat surface. To make sure adhesion is occurring, it helps to really smash the putty against the surface being filled because it is dense but it will stick! If it doesn't pull off, then it has stuck. Usually it is possible to get the material somewhat close to the desired contour but it sands well if not. If the areas is quite large, then several layers will be beneficial. Then the material won't be setting with the result of fighting with it. The material adheres to itself as well as the wood. Once set, it can be drilled, sanded, painted. It will NOT rot! If you live in a humid climate and have to stay on top of exterior wood, this material is a huge help.

I honestly prefer the abatron product but it’s often twice the price.I used this product after soaking the rotted wood with abatron liqui-wood. Products appear to be compatible. I think the liquiwood or a similar product is essential to stabilize the surrounding wood.I used approximately two gallons of this stuff this summer to repair rot that was 3”-4” deep under some windows along front of my house. Alternative would have involved rebuilding 30’ of wood paneling and windows, so I’m glad this stuff exists.This jb weld product dries to be sandable overnight though sometimes I used a heat gun in the morning to complete the cure. Sanded surface was smooth, the material is extremely tough and primer went over it well. Much much faster than rebuilding with new wood.I let the material puff out of the hole slightly, then sand flush once it is cured. I used a 1/4 sheet detail sander and 120 grit paper to prep for primer. I wiped with anhydrous isopropyl before applying aqua lock acrylic primer, final coat was Benjamin Moore latex.Can’t tell repair occurred, the jb weld looks better than the cedar.

This is a good product. It is easy to mix, doesn't tend to stick to your hands if you mix without gloves, and takes paint well.I'm an electrician and from time to time in residential and commercial applications need to fill a hole or patch a wall and this stuff sets up relatively quickly; it doesn't set up as fast as Bondo or relatively dry mixed Water Putty but does reach a hard set within 40 minutes or so.While this isn't as hard when set as Bondo it is just as, if not more, weather resistant and can be drilled nicely.My only downsides are two fold it is of a strange consistency, not thin and not thick, this can be an upside but means it can't easily be troweled or flattened with a putty knife to get as neat of a finish, without sanding, as Bondo, and it also isn't as thick as J-B Welds stick epoxies meaning it can't be rough formed as well either.I find I use this to fill gaps then cover with either Bondo, Water Putty, or Spackle depending on need.While this will set underwater it is much to thin to do so as effectively as their Marine Stick, but it has worked in the rain with a little protection.I like this, even though it is MUCH more expensive than Duct Seal, to fill gaps and penetrations that don't need a fire rating, as it sets relatively hard.*I would not this is electrically non-conductive and proves a good insulator under CAT III/IV conditions up to and probably even past 1,000 Volts. in a pinch I used this to temporarily fix a glass insulator which broke and for which I didn't have a spare on hand; it worked so well with 0 bleed I almost considered leaving it.
