Scott Dunsworth Posted February 25, 2019 Report Share Posted February 25, 2019 Anyone ever used woodworking filler under epoxy? I always use epoxy with some sort of filler, but this job I'm doing is a little different. I have some screw holes in the deck of my spindrift deck that after the screws are in there just isn't enough room to bung them. My decking is 1/4 inch Birdseye maple and I want to finish it bright. The wood is very blond and the epoxy fillers are just to dark. Anyway Im thinking of using regular wood filler which I can get to match pretty good. Myself I can't see any problem with using it, but most of the time I don't think about everything. Quote Link to comment Share on other sites More sharing options...
Mike Vacanti Posted February 25, 2019 Report Share Posted February 25, 2019 Is the filler oil-based? Quote Link to comment Share on other sites More sharing options...

Chick Ludwig Posted February 25, 2019 Report Share Posted February 25, 2019 I mix wood flour from my sander with cabosil and epoxy to make putty. Of course the wood flour comes from sanding the same kind of wood that I want to match. Quote Link to comment Share on other sites More sharing options...
Hirilonde Posted February 25, 2019 Report Share Posted February 25, 2019 Since you are covering it all in epoxy, and this is just cosmetic, then as long as you are confident the putty bonds well I don't see an issue. Keep in mind that if you can make a repair, you can repair your repair later as well. But like Chick just mentioned, I wouldn't give up on making an epoxy filler that matches quite yet.

Scott Dunsworth Posted February 25, 2019 Author Report Share Posted February 25, 2019 Chick the hardwood flour I got is maple and when mixed it turns dark brown, the pine flour turns light brown. I tried some dust from sanding of this maple and it also turn dark brown. I haven't tried mixing other items with it yet. Quote Link to comment Share on other sites More sharing options...
Reacher Posted February 26, 2019 Report Share Posted February 26, 2019 Scott, I'd say try the plastic wood filler if it gives the color you want. Just let it fully dry before coating it with epoxy. I don't like using a filler with cabosil for spots like screw heads because it is harder than the surrounding surface and therefore doesn't sand the same. Some epoxies mixed with wood flour shrink as they cure and the next season you will see dimples on the surface. And, as you noted, epoxy will darken the wood flour.

Chick Ludwig Posted February 26, 2019 Report Share Posted February 26, 2019 When I mix my filler, I use mostly Cabosil with a little of the wood flour. It seems to stay pretty close to the color i want. You can also use Q-cell with, or instead of the Cabosil if you want it to sand easier.

Scott Dunsworth Posted February 26, 2019 Author Report Share Posted February 26, 2019 Got some filling today on some areas that get painted, I'll do a little experimenting and see what I come up with Chic. Know what you mean on the softer wood around the filler Reacher. My first boat was an Penobscot 14 planked with Okoume which is super soft, ended up with a finish not that great.

Scott Dunsworth Posted February 27, 2019 Author Report Share Posted February 27, 2019 Chic I used off white glass bubbles from Raka then mixed maple flour slowly till it was close. Worked pretty good, thanks for the help all. Sanded real easy, looks good now sanded, we'll see what it looks like after everything is coated. Might have a picture tonight on a new spindrift thread. 1 Quote Link to comment Share on other sites More sharing options...
