System Three Wood Flour, 5 Qt Tub, Brown

I'm very happy to have found this product! I had no idea something like this even existed. I used it in a different way than I have read others have. I made a custom plywood strip floor in my tiny house. Even though I was very precise with the cuts, there was still very small gaps between some of the strips. I mixed this product with a waterproof wood glue until I had a thick paste, which you can see in the photos I've uploaded. I used a body filler spreader to spread the mixture into all the cracks between the boards. Then simply wiped over the top with a damn cloth to lessen any sanding later. It was lighter than my floor color when I first applied, only because the floor had already been polyurethaneed over once before. Once I polyurethaneed the floor again, the mixture soaked up the poly, and is completely invisible! Now my floor has no open seams in it anywhere. No more dirt can get stuck between the boards. Excellent product that can be used in many different ways.

Thickening epoxy can be expensive, right? A tub of this will help if wood flour is acceptable for your application. It is very fine. Fillets come out a little rougher, but not at all bad.

It’s great for simple wood working projects.

UPDATE: Still holding up just fine years later!I used this with wood glue to make putty to repair an antique china cabinet with a broken wooden door pull. It was my only option other than having a new pull hand made from a woodworker. It has worked well so far a month or so out. I have not tugged on this yet but will be trying that out next. I bought this container and used very little for my project, so I am curious to find another use for an almost full container. Definitely will use for a filler where needed in the future.

I understand what this is really designed to do, and we totally used this inappropriately to fill larger gaps and cracks in 100 Year old flooring. We used with Wood Flour Cement which I purchased locally. We made a thicker paste almost like oatmeal, and it's been holding up very well so far. When used like it was designed to, it would even be better

I was mixing up epoxy to fill rotted beams in the structure of my deck. This stuff used as a thickener was just fantastic. I could mix the epoxy to whatever consistency the job needed by just adding an appropriate amount of wood flour. Really, really, impressed, and it solved a big problem for me, i.e. pouring epoxy into a rotted area without having it run out through every little nook and cranny. Do your first coat with straight epoxy to get good penetration into the wood, but subsequent fill applications can be thickened.

This is a lot of wood flour and it mixes into epoxy well. I built a stitch and glue rowboat and hardly made a dent in the tub. I have enough left to do probably another half dozen boat projects. But be aware that this is dark material. I guess that's why they call it brown. The fillet material comes out chocolate colored. Of course I don't care b/c I'm going to paint my boat but if you want natural color his will matter.

I use this to stop minor leaks in my cedar hot tub. Just take out the filter, then throw in the whole bucket of wood dust and turn off the pump. After a couple of days, a fair amount of grit settles. But I reinstall the filter and sweep all the crud into the drain, and after a couple of rounds, it's all good.
