WoodEpox Kit - 2 Pint - 2-Part Structural Epoxy Adhesive Filler - Wood Filler Putty

This product is great if you need to match the profile of the non-rotted wood. I used it to repair the rotted wood corner of a door, which I thought would be impossible to repair without replacing the wood. It has a long work time, unlike some epoxies and is easy to sand, especially with a Drexel Multi-Max. You can shape it with tools. I actually used a paint stick and popsicle sticks to match the existing door edges. You want to make sure you mix the two parts well and is a solid tan color. If you don’t mix well, you won’t get a good cure and the stuff will crumble. Found that out on my first attempt using the product. It is expensive compared to other wood fillers, but the ability to work it really stands out. Bondo wood filler works well to fill large areas, but is better on flat surfaces because it sets up too fast and is too mushy to work before it hardens. QuikWood is easy to use and works well for filling holes, but much firmer so hard to use to match a profile. The non-epoxy wood fillers have not given me lasting repairs on exterior wood. The stuff also goes a long way. I’ve used the same small containers to make multiple repairs. You also want to make sure you use a wood hardener on the rotted wood (e.g. LiquidWood) to give the epoxy a firm surface to stick to. If possible, I drive stainless steel screws into the hardened rot into the fresh wood underneath, leaving the screw head and part of the screw out to give the epoxy more to adhere to and provide a stronger repair.

I actually like this stuff for filling "happy accidents" in paint grade projects. I will note that what I have is very soft and easy to mix the two parts in your hand. I suggest to the reviewers that are saying the product is dry, crumbly, difficult to mix. etc that they have bad product and should return it. This stuff, when right, is easy to combine and easy to place. I seriously don't recommend replacing huge sections of rotted wood with it though, the cost is prohibitive for that. Saw out the bad lumber and replace it. Use this stuff to conceal the joints, screw holes and the like. If you happen to drill a hole in the wrong place, this product works great to make that go away. It does cure rather slow, so don't expect 5 minute epoxy. Not the answer to every problem but worth having around the shop for sure.

I have used all sorts of materials for filling and patching rotted or damaged wood. This stuff is the best I have used. It is easy to mix, doesn't kill half my brain cells from heavy fumes and finishes off nicely with sanding and paint. My initial impression when I first handled it was that it was too light and fluffy to make substantial repairs. It also seemed like it couldn't possibly bond to the wood very well. Once dried though it was solidly bonded and hard but sandable. Once painted you wouldn't know there is a repair. Adding the two part LiquidWood to the project makes it even better. You can use that to consolidate spongy wood and increase the ability for the filler to bond. Add a tiny bit of the liquid to the filler to thin it for a more spreadable consistency. Overall this is a great system for wood repair.

Product worked great to patch older wood failures on 1950s home.

This is the best wood filler and reconstruction filler on the market. It works incredibly well and can be hand worked, or tool applied. It's possible to thin the material with wood harder, or their product thinner. You can also extend the hardening time to more easily work in the material into deeper areas or rotted wood that has been pre-hardened. It is best to put this in the area to be filled while the wood harder is still a little tacky. This product does have quite a learning curve, but that's because there is nothing else like it out there.

Seemed dubious at first but wow .. this stuff eventually sets up into a rock-hard but workable material. Amazing stuff, worth the money for what it can accomplish.

My front door faces west and catches the sun, it's original to the house and 50 years old. The spar protective finish had faded and over time there was a bit of wicking from the bottom and veneer seams had opened in a couple of places. This epoxy was just what I needed. You can work a little stain into the epoxy so the color matches the wood. Easy to use and good results, new spar finish adhered just fine and doors look great.

It is surprisingly light weight. It is workable for a reasonable time, curing much more slowly than liquid epoxies, bondo paste, or the usual wood fillers. It sands and shapes easily, and for complex profiles should yield better and easier results than alternatives. However, I question its bonding power and durability. It's difficult to apply without leaving small voids, it isn't as sticky as other products, and it is softer. Screw hold will probably be pretty weak. Tooling requires wetting your tool with alcohol with each pass to get a smooth-ish profile. It will hold in place and keep its shape far better than softer or more liquid alternatives. You'll want to power sand with finer grit to get a smooth surface before priming and painting. Using wood hardener before applying is likely more critical for bond than with liquid epoxy and is recommended in the directions. All in all, I judge it a good product for use in the right application. Whether that includes my rot repair to a wood storm window panel -- exposed to sun and weather -- remains to be seen. After trying the product, I think I'd avoid using in locations that see big temperature swings or vibration. For repairs to damaged trim, such as indoors or on a protected doorframe, however, it seems a very good product and DIY friendly. Unfortunately, mine had been previously opened and used.
