Topic tags/keywords: question

I have a knot to fill a bout the size of a quarter in the workbench top I am working on. The top is cherry and I want to fill the hole with black or a very dark brown epoxy. I have some black oil based paint and walnut oil based stain and was wondering if a couple drops of either of these can be used as an acceptable method to color epoxy.

Any help and direction is appreciated.

You can usually color epoxy but I would do a test first and see how it comes out.

I havent tried using epoxy, but I have used a mixture of polyurethane glue and fine sawdust from the wood I was filling. I filled some knots and it worked great. I tinted the whole mixture with the stain that I was going to eventually use on the piece. Then when I stained the piece I went right over the patched spots again and it turned the knot holes slightly darker than the rest of it.

Matching sawdust would be pretty good. One thing that they use is graphite. It will color it and be kind of slick too. I would not use other chemicals. Inert solids only.

I recently tried this tint called Mixol at WoodCraft.
It can be added to epoxy and comes in a wide variety of colors.
The small bottles, 20 ml, are $5.50 and one to two drops is all you need.
I found it still allowed the epoxy to set up good and hard, and sanded well.
I used black to fill some voids in ebony without a trace of suspicion of being filled.

I just use acrylic craft paint. I was worried about using water based stuff, but it did fine.
Some use artist’s oils.
When I use saw dust, I stain the saw dust to match the wood’s final finish first. that’s only if the repair(?) is not decorative. Most often the defects become a “design element”...hehehe. When you work with mesquite, you find a whole lot of “design elements!

I have to fill knots all the time. Epoxy is the best way to do it without a doubt. I use T-88 fast cure and tint them black either with a black tint from T-88 or brown using T-88 and bit of walnut sanding dust. Mix it up in a small serving cup (like you see catsup come in at the fast food places) with a popsicle stick (found at Wal-Mart craft area). I’ve used artist’s oils with great results too. This technique can also be used for joint mistakes as long as the gap isn’t too big. If its humongous then use stained epoxy and slip in small slivers of wood into the joint.

Good Luck!

You can get many different epoxy tints from ceramic tile supply companies. I use it at times and it works great. Just mix it with epoxy and hardener in the normal way.

Hey Jocks,

Well I did it. I tried the stain and it look a little milky so I tried the toner and it worked good.

Thanks for the help!

Marc,

There are also powdered dyes you can try out there. Remember though, additives can effect the cure time of your epoxy.

A 2nd for Milo’s approach. I much prefer the powdered dyes mixed with epoxy as I’ve had less predictable results using any liquid dyes, etc. For small fills, powdered sawdust and CA works fairly well.
