Amazing Clear Cast stays clear [amazon link]. It is slow setting so gives air bubbles more of a chance to get out.

It is hard to say whether yours turned white because it cures that way, or because it just cured fast and ended up with a lot of air bubbles.

Can’t offer any advice on epoxy but I will offer a different approach to crack filling.

Try packing the crack/hole with fine sanding dust and then drenching with CA. It will harden nicely and turn a very dark brown or black. It can be sanded smooth and it’s very difficult to tell that a repair was made.

This works well with dark woods or knots but the crack line is visible on lighter woods. Can be used as an accent feature, if desired.

The sanding dust/CA glue method mentioned earlier works great. Be sure to use thin CA. You can also get colored pigments for your epoxy to help blend in with where you’re applying it. System Three makes some, or you can use Mixol pigments available at Woodcraft.

Finally, epoxy putty is available in many colors that can be blended to further extend the color range. They are stable and sand easily.

For that dark brown knot, mix your epoxy well, then add in some used coffee grounds. You can tint epoxy with any number of things you may have around the house.

You could go dumpster-diving out back of your local Denny’s. Just don’t get caught. It’d be hard to explain.

Edit: On second thought Starbucks might offer a wider array of grounds to choose from. It could become your signature look.

It doesn’t have to be used… I just hate wasting good coffee :)

You can color epoxy with just about anything. Chalk works well and can be had in a ton of different colors. Sawdust works as well, and will be darker than original. Metal shavings, crushed rock, various spices found in your cabinet, talcum powder, graphite (from pencil shavings), many paints, inks and dyes, shredded fabrics, aluminum foil, etc… just use your imagination and if unsure, test a small sample first.

Cheers,
Brad

Honestly, you’re joking, right? This is LumberJocks, not Martha Stewart.

Like I said, there are pigments for epoxy that you can blend to any color.

Nope.. dead serious – they all work and work well. Coffee however is probably the most common.
